ffmpeg-statigo

Real FFmpeg bindings for Go. Not a wrapper. Not a CLI tool. The actual libraries.

Cross-platform, static FFmpeg libraries bundled directly into your Go binary. Hardware acceleration included. Zero runtime dependencies. Ship it and forget it.

Why This Exists

Every other Go ffmpeg projects wrap the ffmpeg command, ffmpeg-statigo gives you the actual FFmpeg C libraries with proper Go bindings. Build once, deploy anywhere. No hunting for system FFmpeg. No version mismatches. Predictable codec support.

Features

FFmpeg 8.0.1 - Latest release with AV1, H.265, H.264, VP8/9
Truly static - Builds into your binary (just needs system m and stdc++ libraries)
Cross-platform - Linux and macOS (arm64, amd64)
Hardware acceleration - NVENC/NVDEC, QuickSync, VA-API, VideoToolbox, and Vulkan support
GPL build - x264, x265, and all the good codecs included
Auto-generated - Thin, predictable bindings directly from FFmpeg headers
Preserved documentation - Original FFmpeg comments in your IDE

Hard fork of the excellent csnewman/ffmpeg-go, modernised with FFmpeg 8.0.x, Go 1.24, hardware acceleration, ~85% FFmpeg API coverage, and a 99.5% smaller git history.

Installation

Static libraries (~100MB per platform) cannot be distributed via go get. Use as a git submodule with a replace directive:

Add submodule: git submodule add https://github.com/linuxmatters/ffmpeg-statigo third_party/ffmpeg-statigo
Add replace directive to go.mod: replace github.com/linuxmatters/ffmpeg-statigo => ./third_party/ffmpeg-statigo
Download libraries: cd third_party/ffmpeg-statigo && go run ./cmd/download-lib
Configure git for submodule-friendly pulls: git config pull.ff only && git config submodule.recurse true
Build: go build ./...

Step 4 prevents git pull --rebase from breaking submodule references. Fast-forward only pulls ensure submodule commits stay in sync with the parent repository.

Static libraries are gitignored—only the submodule reference is committed.

See docs/DEVELOPMENT.md for CI/CD integration, cross-compilation, and troubleshooting.

Codec Inclusion Policy

ffmpeg-statigo provides a curated FFmpeg static library focused on the core strengths of FFmpeg: decoding, processing, and encoding audio and video streams. ffmpeg-statigo is designed for Go developers building modern streaming applications. The pattern is:

Generate content in Go - Text, graphics, effects using Go's excellent libraries
Feed frames to FFmpeg - Use ffmpeg-statigo for encoding and stream processing
Let FFmpeg handle codecs - Hardware acceleration, format conversion, container muxing

What's Included

Decoders: All contemporary formats (H.264, H.265, AV1, VP8/9, Opus, AAC, MP3)
Encoders: Modern codecs for streaming and transcoding (x264, x265, dav1d, rav1e, vpx, lame, opus)
Hardware acceleration: NVENC, QuickSync, VA-API, VideoToolbox, Vulkan Video
Containers: MP4, MKV, WebM, DASH, HLS, and all major formats
Filters: Video scaling, colour conversion, audio resampling, and processing filters
Streaming protocols: RTMP, SRT, HLS, DASH

Building something that deals with video? You're probably covered:

Streaming platform (your own Twitch/YouTube/Owncast)
Content management system with media handling
Social media app with video uploads
Video conferencing service
Transcoding pipeline for your media library
Home media server ripping DVDs/Blu-rays
Web-based media player
Broadcasting tool or modern content creation workflow

What's Intentionally Absent

Some FFmpeg features commonly found in the ffmpeg CLI tool are not included because they're better implemented in Go:

❌ drawtext filter - Use Go's image/draw + golang.org/x/image/font packages instead
❌ Font libraries (freetype, harfbuzz, fontconfig) - Not needed when rendering in Go
❌ subtitles and ass filters - Use separate subtitle streams instead
❌ libass - Subtitle rendering library not needed
- FFmpeg can still copy, extract, and mux subtitle streams without libass.

The excluded features can be added back if a compelling use case emerges. ffmpeg-statigo is a living project and the curated library evolves based on real-world needs.

If you need complete FFmpeg with all filters, use the official FFmpeg distribution. If you need modern streaming codecs with Go integration, ffmpeg-statigo is designed for you.

Licensing

The Go binding code is MIT licensed. However, the bundled FFmpeg libraries are compiled with GPL-licensed components like x264 and x265. Any project using ffmpeg-statigo inherits the GPL requirements from FFmpeg through this linking, making the combined work subject to GPLv3 licensing obligations.

Documentation ¶

Overview ¶

Package ffmpeg provides Go bindings to FFmpeg 8.0 libraries.

This package includes static FFmpeg libraries with hardware acceleration support (NVENC, VideoToolbox, Vulkan, QuickSync) and contemporary codecs (H.264, H.265, VP8/9, AV1).

The package provides direct access to FFmpeg's C API through CGO bindings. All FFmpeg functions are available with their original names prefixed with AV*.

Example usage:

import "github.com/linuxmatters/ffmpeg-statigo"

func main() {
	var ctx *ffmpeg.AVFormatContext
	url := ffmpeg.ToCStr("input.mp4")
	defer url.Free()

	_, err := ffmpeg.AVFormatOpenInput(&ctx, url, nil, nil)
	if err != nil {
		panic(err)
	}
	defer ffmpeg.AVFormatFreeContext(ctx)
}

For complete examples, see the examples/ directory.

                  - `1` is replaced by the maximum value for automatic storage
                      any large value means that the internal buffer will be
                      reallocated as needed up to that limit
                  - `-1` is converted to `UINT_MAX`, the largest limit possible.
                  Check also `AV_BPRINT_SIZE_*` macros.

func AVBprintInitForBuffer ¶

func AVBprintInitForBuffer(buf *AVBPrint, buffer *CStr, size uint)

AVBprintInitForBuffer wraps av_bprint_init_for_buffer.

Init a print buffer using a pre-existing buffer.

func AVBprintIsComplete ¶

func AVBprintIsComplete(buf *AVBPrint) (int, error)

AVBprintIsComplete wraps av_bprint_is_complete.

Test if the print buffer is complete (not truncated).

It may have been truncated due to a memory allocation failure
or the size_max limit (compare size and size_max if necessary).

func AVBsfAlloc ¶

func AVBsfAlloc(filter *AVBitStreamFilter, ctx **AVBSFContext) (int, error)

AVBsfAlloc wraps av_bsf_alloc.

@return >=0 on success, negative AVERROR in case of failure

func AVBsfListFinalize ¶

func AVBsfListFinalize(lst **AVBSFList, bsf **AVBSFContext) (int, error)

AVBsfListFinalize wraps av_bsf_list_finalize.

Finalize list of bitstream filters.

This function will transform @ref AVBSFList to single @ref AVBSFContext,
so the whole chain of bitstream filters can be treated as single filter
freshly allocated by av_bsf_alloc().
If the call is successful, @ref AVBSFList structure is freed and lst
will be set to NULL. In case of failure, caller is responsible for
freeing the structure by av_bsf_list_free()

@param      lst Filter list structure to be transformed
@param[out] bsf Pointer to be set to newly created @ref AVBSFContext structure
                representing the chain of bitstream filters

@ref AVBSFContext describing the whole chain of bitstream filters.
Resulting @ref AVBSFContext can be treated as any other @ref AVBSFContext freshly
allocated by av_bsf_alloc().

@param      str String describing chain of bitstream filters in format
                `bsf1[=opt1=val1:opt2=val2][,bsf2]`

func AVBsfReceivePacket ¶

func AVBsfReceivePacket(ctx *AVBSFContext, pkt *AVPacket) (int, error)

AVBsfReceivePacket wraps av_bsf_receive_packet.

Retrieve a filtered packet.

@param ctx an initialized AVBSFContext
@param[out] pkt this struct will be filled with the contents of the filtered
                packet. It is owned by the caller and must be freed using
                av_packet_unref() when it is no longer needed.
                This parameter should be "clean" (i.e. freshly allocated
                with av_packet_alloc() or unreffed with av_packet_unref())
                when this function is called. If this function returns
                successfully, the contents of pkt will be completely
                overwritten by the returned data. On failure, pkt is not
                touched.

@return
 - 0 on success.
 - AVERROR(EAGAIN) if more packets need to be sent to the filter (using
   av_bsf_send_packet()) to get more output.
 - AVERROR_EOF if there will be no further output from the filter.
 - Another negative AVERROR value if an error occurs.

@note one input packet may result in several output packets, so after sending
a packet with av_bsf_send_packet(), this function needs to be called
repeatedly until it stops returning 0. It is also possible for a filter to
output fewer packets than were sent to it, so this function may return
AVERROR(EAGAIN) immediately after a successful av_bsf_send_packet() call.

func AVBsfSendPacket ¶

func AVBsfSendPacket(ctx *AVBSFContext, pkt *AVPacket) (int, error)

AVBsfSendPacket wraps av_bsf_send_packet.

Submit a packet for filtering.

After sending each packet, the filter must be completely drained by calling
av_bsf_receive_packet() repeatedly until it returns AVERROR(EAGAIN) or
AVERROR_EOF.

@param ctx an initialized AVBSFContext
@param pkt the packet to filter. The bitstream filter will take ownership of
the packet and reset the contents of pkt. pkt is not touched if an error occurs.
If pkt is empty (i.e. NULL, or pkt->data is NULL and pkt->side_data_elems zero),
it signals the end of the stream (i.e. no more non-empty packets will be sent;
sending more empty packets does nothing) and will cause the filter to output
any packets it may have buffered internally.

@return
 - 0 on success.
 - AVERROR(EAGAIN) if packets need to be retrieved from the filter (using
   av_bsf_receive_packet()) before new input can be consumed.
 - Another negative AVERROR value if an error occurs.

AVBufferDefaultFree wraps av_buffer_default_free.

Default free callback, which calls av_free() on the buffer data.
This function is meant to be passed to av_buffer_create(), not called
directly.

func AVBufferGetOpaque ¶

func AVBufferGetOpaque(buf *AVBufferRef) unsafe.Pointer

AVBufferGetOpaque wraps av_buffer_get_opaque.

@return the opaque parameter set by av_buffer_create.

func AVBufferGetRefCount ¶

Return 0 otherwise.
A positive answer is valid until av_buffer_ref() is called on buf.

func AVBufferMakeWritable ¶

func AVBufferMakeWritable(buf **AVBufferRef) (int, error)

AVBufferMakeWritable wraps av_buffer_make_writable.

Create a writable reference from a given buffer reference, avoiding data copy
if possible.

@param buf buffer reference to make writable. On success, buf is either left
           untouched, or it is unreferenced and a new writable AVBufferRef is
           written in its place. On failure, buf is left untouched.
@return 0 on success, a negative AVERROR on failure.

func AVBufferPoolBufferGetOpaque ¶

func AVBufferPoolBufferGetOpaque(ref *AVBufferRef) unsafe.Pointer

AVBufferPoolBufferGetOpaque wraps av_buffer_pool_buffer_get_opaque.

Query the original opaque parameter of an allocated buffer in the pool.

@param ref a buffer reference to a buffer returned by av_buffer_pool_get.
@return the opaque parameter set by the buffer allocator function of the
        buffer pool.

@note the opaque parameter of ref is used by the buffer pool implementation,
therefore you have to use this function to access the original opaque
parameter of an allocated buffer.

func AVBufferPoolUninit ¶

func AVBufferPoolUninit(pool **AVBufferPool)

AVBufferPoolUninit wraps av_buffer_pool_uninit.

Mark the pool as being available for freeing. It will actually be freed only
once all the allocated buffers associated with the pool are released. Thus it
is safe to call this function while some of the allocated buffers are still
in use.

@param pool pointer to the pool to be freed. It will be set to NULL.

func AVBufferRealloc ¶

func AVBufferRealloc(buf **AVBufferRef, size uint64) (int, error)

AVBufferRealloc wraps av_buffer_realloc.

Reallocate a given buffer.

@param buf  a buffer reference to reallocate. On success, buf will be
            unreferenced and a new reference with the required size will be
            written in its place. On failure buf will be left untouched. *buf
            may be NULL, then a new buffer is allocated.
@param size required new buffer size.
@return 0 on success, a negative AVERROR on failure.

@note the buffer is actually reallocated with av_realloc() only if it was
initially allocated through av_buffer_realloc(NULL) and there is only one
reference to it (i.e. the one passed to this function). In all other cases
a new buffer is allocated and the data is copied.

func AVBufferReplace(dst **AVBufferRef, src *AVBufferRef) (int, error)

AVBufferReplace wraps av_buffer_replace.

Ensure dst refers to the same data as src.

When *dst is already equivalent to src, do nothing. Otherwise unreference dst
and replace it with a new reference to src.

@param dst Pointer to either a valid buffer reference or NULL. On success,
           this will point to a buffer reference equivalent to src. On
           failure, dst will be left untouched.
@param src A buffer reference to replace dst with. May be NULL, then this
           function is equivalent to av_buffer_unref(dst).
@return 0 on success
        AVERROR(ENOMEM) on memory allocation failure.

func AVBufferUnref ¶

func AVBufferUnref(buf **AVBufferRef)

AVBufferUnref wraps av_buffer_unref.

@param ctx pointer to a context of a buffersink or abuffersink AVFilter.
@param frame pointer to an allocated frame that will be filled with data.
             The data must be freed using av_frame_unref() / av_frame_free()

@return
        - >= 0 if a frame was successfully returned.
        - AVERROR(EAGAIN) if no frames are available at this point; more
          input frames must be added to the filtergraph to get more output.
        - AVERROR_EOF if there will be no more output frames on this sink.
        - A different negative AVERROR code in other failure cases.

func AVBuffersinkGetFrameFlags ¶

func AVBuffersinkGetFrameFlags(ctx *AVFilterContext, frame *AVFrame, flags int) (int, error)

func AVBuffersinkGetSamples(ctx *AVFilterContext, frame *AVFrame, nbSamples int) (int, error)

AVBuffersinkGetSamples wraps av_buffersink_get_samples.

Same as av_buffersink_get_frame(), but with the ability to specify the number
of samples read. This function is less efficient than
av_buffersink_get_frame(), because it copies the data around.

@param ctx pointer to a context of the abuffersink AVFilter.
@param frame pointer to an allocated frame that will be filled with data.
             The data must be freed using av_frame_unref() / av_frame_free()
             frame will contain exactly nb_samples audio samples, except at
             the end of stream, when it can contain less than nb_samples.

@return The return codes have the same meaning as for
        av_buffersink_get_frame().

@warning do not mix this function with av_buffersink_get_frame(). Use only one or
the other with a single sink, not both.

exactly the specified number of samples, or AVERROR(EAGAIN) if there is
not enough. The last buffer at EOF will be padded with 0.

func AVBuffersrcAddFrame ¶

func AVBuffersrcAddFrame(ctx *AVFilterContext, frame *AVFrame) (int, error)

AVBuffersrcAddFrame wraps av_buffersrc_add_frame.

Add a frame to the buffer source.

@param ctx   an instance of the buffersrc filter
@param frame frame to be added. If the frame is reference counted, this
function will take ownership of the reference(s) and reset the frame.
Otherwise the frame data will be copied. If this function returns an error,
the input frame is not touched.

@return 0 on success, a negative AVERROR on error.

@note the difference between this function and av_buffersrc_write_frame() is
that av_buffersrc_write_frame() creates a new reference to the input frame,
while this function takes ownership of the reference passed to it.

This function is equivalent to av_buffersrc_add_frame_flags() without the
AV_BUFFERSRC_FLAG_KEEP_REF flag.

func AVBuffersrcAddFrameFlags ¶

func AVBuffersrcAddFrameFlags(bufferSrc *AVFilterContext, frame *AVFrame, flags int) (int, error)

AVBuffersrcAddFrameFlags wraps av_buffersrc_add_frame_flags.

ownership of the reference(s) and reset the frame. This can be controlled
using the flags.

If this function returns an error, the input frame is not touched.

@param buffer_src  pointer to a buffer source context
@param frame       a frame, or NULL to mark EOF
@param flags       a combination of AV_BUFFERSRC_FLAG_*
@return            >= 0 in case of success, a negative AVERROR code
                   in case of failure

func AVBuffersrcClose ¶

func AVBuffersrcClose(ctx *AVFilterContext, pts int64, flags uint) (int, error)

AVBuffersrcClose wraps av_buffersrc_close.

Close the buffer source after EOF.

This is similar to passing NULL to av_buffersrc_add_frame_flags()
except it takes the timestamp of the EOF, i.e. the timestamp of the end
of the last frame.

func AVBuffersrcGetNbFailedRequests ¶

func AVBuffersrcGetNbFailedRequests(bufferSrc *AVFilterContext) uint

AVBuffersrcGetNbFailedRequests wraps av_buffersrc_get_nb_failed_requests.

A failed request is when the request_frame method is called while no
frame is present in the buffer.
The number is reset when a frame is added.

func AVBuffersrcParametersSet ¶

func AVBuffersrcParametersSet(ctx *AVFilterContext, param *AVBufferSrcParameters) (int, error)

AVBuffersrcParametersSet wraps av_buffersrc_parameters_set.

Initialize the buffersrc or abuffersrc filter with the provided parameters.
This function may be called multiple times, the later calls override the
previous ones. Some of the parameters may also be set through AVOptions, then
whatever method is used last takes precedence.

@param ctx an instance of the buffersrc or abuffersrc filter
@param param the stream parameters. The frames later passed to this filter
             must conform to those parameters. All the allocated fields in
             param remain owned by the caller, libavfilter will make internal
             copies or references when necessary.
@return 0 on success, a negative AVERROR code on failure.

func AVBuffersrcWriteFrame ¶

func AVBuffersrcWriteFrame(ctx *AVFilterContext, frame *AVFrame) (int, error)

AVBuffersrcWriteFrame wraps av_buffersrc_write_frame.

Add a frame to the buffer source.

@param ctx   an instance of the buffersrc filter
@param frame frame to be added. If the frame is reference counted, this
function will make a new reference to it. Otherwise the frame data will be
copied.

@return 0 on success, a negative AVERROR on error

This function is equivalent to av_buffersrc_add_frame_flags() with the
AV_BUFFERSRC_FLAG_KEEP_REF flag.

func AVCalloc ¶

func AVCalloc(nmemb uint64, size uint64) unsafe.Pointer

AVCalloc wraps av_calloc.

Allocate a memory block for an array with av_mallocz().

@param buf_size size in bytes of the buffer.
@param channel the AVChannel whose description to get
@return amount of bytes needed to hold the output string, or a negative AVERROR
        on failure. If the returned value is bigger than buf_size, then the
        string was truncated.

func AVChannelDescriptionBprint ¶

Check whether two channel layouts are semantically the same, i.e. the same
channels are present on the same positions in both.

be constructed without using this.

@param channel_layout the layout structure to be initialized
@param nb_channels the number of channels

@param buf pre-allocated buffer where to put the generated string
@param buf_size size in bytes of the buffer.

func AVChannelLayoutFromMask(channelLayout *AVChannelLayout, mask uint64) (int, error)

AVChannelLayoutFromMask wraps av_channel_layout_from_mask.

Initialize a native channel layout from a bitmask indicating which channels
are present.

@param channel_layout the layout structure to be initialized
@param mask bitmask describing the channel layout

@return 0 on success
        AVERROR(EINVAL) for invalid mask values

func AVChannelLayoutFromString ¶

func AVChannelLayoutFromString(channelLayout *AVChannelLayout, str *CStr) (int, error)

AVChannelLayoutFromString wraps av_channel_layout_from_string.

Initialize a channel layout from a given string description.
The input string can be represented by:
 - the formal channel layout name (returned by av_channel_layout_describe())
 - single or multiple channel names (returned by av_channel_name(), eg. "FL",
   or concatenated with "+", each optionally containing a custom name after
   a "@", eg. "FL@Left+FR@Right+LFE")
 - a decimal or hexadecimal value of a native channel layout (eg. "4" or "0x4")
 - the number of channels with default layout (eg. "4c")
 - the number of unordered channels (eg. "4C" or "4 channels")
 - the ambisonic order followed by optional non-diegetic channels (eg.
   "ambisonic 2+stereo")
On error, the channel layout will remain uninitialized, but not necessarily
untouched.

@param channel_layout uninitialized channel layout for the result
@param str string describing the channel layout
@return 0 on success parsing the channel layout
        AVERROR(EINVAL) if an invalid channel layout string was provided

Get the index in a channel layout of a channel described by the given string.
In case multiple channels are found, only the first match will be returned.

This function accepts channel names in the same format as
@ref av_channel_from_string().

@param channel_layout input channel layout
@param name string describing the channel whose index to obtain
@return a channel index described by the given string, or a negative AVERROR
        value.

func AVChannelLayoutRetype ¶

func AVChannelLayoutRetype(channelLayout *AVChannelLayout, order AVChannelOrder, flags int) (int, error)

AVChannelLayoutRetype wraps av_channel_layout_retype.

Change the AVChannelOrder of a channel layout.

Change of AVChannelOrder can be either lossless or lossy. In case of a
lossless conversion all the channel designations and the associated channel
names (if any) are kept. On a lossy conversion the channel names and channel
designations might be lost depending on the capabilities of the desired
AVChannelOrder. Note that some conversions are simply not possible in which
case this function returns AVERROR(ENOSYS).

The following conversions are supported:

Any       -> Custom     : Always possible, always lossless.
Any       -> Unspecified: Always possible, lossless if channel designations
  are all unknown and channel names are not used, lossy otherwise.
Custom    -> Ambisonic  : Possible if it contains ambisonic channels with
  optional non-diegetic channels in the end. Lossy if the channels have
  custom names, lossless otherwise.
Custom    -> Native     : Possible if it contains native channels in native
    order. Lossy if the channels have custom names, lossless otherwise.

On error this function keeps the original channel layout untouched.

@param channel_layout channel layout which will be changed
@param order the desired channel layout order
@param flags a combination of AV_CHANNEL_LAYOUT_RETYPE_FLAG_* constants
@return 0 if the conversion was successful and lossless or if the channel
          layout was already in the desired order
        >0 if the conversion was successful but lossy
        AVERROR(ENOSYS) if the conversion was not possible (or would be
          lossy and AV_CHANNEL_LAYOUT_RETYPE_FLAG_LOSSLESS was specified)
        AVERROR(EINVAL), AVERROR(ENOMEM) on error

func AVChannelLayoutSubset ¶

func AVChannelLayoutSubset(channelLayout *AVChannelLayout, mask uint64) uint64

AVChannelLayoutSubset wraps av_channel_layout_subset.

Find out what channels from a given set are present in a channel layout,
without regard for their positions.

@return amount of bytes needed to hold the output string, or a negative AVERROR
        on failure. If the returned value is bigger than buf_size, then the
        string was truncated.

func AVCodecAlignDimensions ¶

func AVCodecAlignDimensions(s *AVCodecContext, width *int, height *int)

AVCodecAlignDimensions wraps avcodec_align_dimensions.

buffer that is acceptable for the codec if you do not use any horizontal
padding.

func AVCodecDecodeSubtitle2 ¶

func AVCodecDecodeSubtitle2(avctx *AVCodecContext, sub *AVSubtitle, gotSubPtr *int, avpkt *AVPacket) (int, error)

AVCodecDecodeSubtitle2 wraps avcodec_decode_subtitle2.

Decode a subtitle message.
Return a negative value on error, otherwise return the number of bytes used.
If no subtitle could be decompressed, got_sub_ptr is zero.
Otherwise, the subtitle is stored in *sub.
Note that AV_CODEC_CAP_DR1 is not available for subtitle codecs. This is for
simplicity, because the performance difference is expected to be negligible
and reusing a get_buffer written for video codecs would probably perform badly
due to a potentially very different allocation pattern.

Some decoders (those marked with AV_CODEC_CAP_DELAY) have a delay between input
and output. This means that for some packets they will not immediately
produce decoded output and need to be flushed at the end of decoding to get
all the decoded data. Flushing is done by calling this function with packets
with avpkt->data set to NULL and avpkt->size set to 0 until it stops
returning subtitles. It is safe to flush even those decoders that are not
marked with AV_CODEC_CAP_DELAY, then no subtitles will be returned.

@note The AVCodecContext MUST have been opened with @ref avcodec_open2()
before packets may be fed to the decoder.

@param avctx the codec context
@param[out] sub The preallocated AVSubtitle in which the decoded subtitle will be stored,
                must be freed with avsubtitle_free if *got_sub_ptr is set.
@param[in,out] got_sub_ptr Zero if no subtitle could be decompressed, otherwise, it is nonzero.
@param[in] avpkt The input AVPacket containing the input buffer.

func AVCodecDefaultGetBuffer2 ¶

func AVCodecDefaultGetBuffer2(s *AVCodecContext, frame *AVFrame, flags int) (int, error)

AVCodecDefaultGetBuffer2 wraps avcodec_default_get_buffer2.

The default callback for AVCodecContext.get_buffer2(). It is made public so
it can be called by custom get_buffer2() implementations for decoders without
AV_CODEC_CAP_DR1 set.

func AVCodecDefaultGetEncodeBuffer ¶

func AVCodecDefaultGetEncodeBuffer(s *AVCodecContext, pkt *AVPacket, flags int) (int, error)

AVCodecDefaultGetEncodeBuffer wraps avcodec_default_get_encode_buffer.

The default callback for AVCodecContext.get_encode_buffer(). It is made public so
it can be called by custom get_encode_buffer() implementations for encoders without
AV_CODEC_CAP_DR1 set.

func AVCodecEncodeSubtitle ¶

func AVCodecEncodeSubtitle(avctx *AVCodecContext, buf unsafe.Pointer, bufSize int, sub *AVSubtitle) (int, error)

AVCodecEncodeSubtitle wraps avcodec_encode_subtitle.

func AVCodecFillAudioFrame ¶

func AVCodecFillAudioFrame(frame *AVFrame, nbChannels int, sampleFmt AVSampleFormat, buf unsafe.Pointer, bufSize int, align int) (int, error)

AVCodecFillAudioFrame wraps avcodec_fill_audio_frame.

Fill AVFrame audio data and linesize pointers.

The buffer buf must be a preallocated buffer with a size big enough
to contain the specified samples amount. The filled AVFrame data
pointers will point to this buffer.

AVFrame extended_data channel pointers are allocated if necessary for
planar audio.

@param frame       the AVFrame
                   frame->nb_samples must be set prior to calling the
                   function. This function fills in frame->data,
                   frame->extended_data, frame->linesize[0].
@param nb_channels channel count
@param sample_fmt  sample format
@param buf         buffer to use for frame data
@param buf_size    size of buffer
@param align       plane size sample alignment (0 = default)
@return            >=0 on success, negative error code on failure
@todo return the size in bytes required to store the samples in
case of success, at the next libavutil bump

func AVCodecFlushBuffers ¶

func AVCodecFlushBuffers(avctx *AVCodecContext)

AVCodecFlushBuffers wraps avcodec_flush_buffers.

Reset the internal codec state / flush internal buffers. Should be called
e.g. when seeking or when switching to a different stream.

@note for decoders, this function just releases any references the decoder
might keep internally, but the caller's references remain valid.

@note for encoders, this function will only do something if the encoder
declares support for AV_CODEC_CAP_ENCODER_FLUSH. When called, the encoder
will drain any remaining packets, and can then be reused for a different
stream (as opposed to sending a null frame which will leave the encoder
in a permanent EOF state after draining). This can be desirable if the
cost of tearing down and replacing the encoder instance is high.

func AVCodecFreeContext ¶

func AVCodecFreeContext(avctx **AVCodecContext)

AVCodecFreeContext wraps avcodec_free_context.

Free the codec context and everything associated with it and write NULL to
the provided pointer.

func AVCodecGetHWFramesParameters ¶

func AVCodecGetHWFramesParameters(avctx *AVCodecContext, deviceRef *AVBufferRef, hwPixFmt AVPixelFormat, outFramesRef **AVBufferRef) (int, error)

AVCodecGetHWFramesParameters wraps avcodec_get_hw_frames_parameters.

Create and return a AVHWFramesContext with values adequate for hardware
decoding. This is meant to get called from the get_format callback, and is
a helper for preparing a AVHWFramesContext for AVCodecContext.hw_frames_ctx.
This API is for decoding with certain hardware acceleration modes/APIs only.

The returned AVHWFramesContext is not initialized. The caller must do this
with av_hwframe_ctx_init().

Calling this function is not a requirement, but makes it simpler to avoid
codec or hardware API specific details when manually allocating frames.

Alternatively to this, an API user can set AVCodecContext.hw_device_ctx,
which sets up AVCodecContext.hw_frames_ctx fully automatically, and makes
it unnecessary to call this function or having to care about
AVHWFramesContext initialization at all.

There are a number of requirements for calling this function:

- It must be called from get_format with the same avctx parameter that was
  passed to get_format. Calling it outside of get_format is not allowed, and
  can trigger undefined behavior.
- The function is not always supported (see description of return values).
  Even if this function returns successfully, hwaccel initialization could
  fail later. (The degree to which implementations check whether the stream
  is actually supported varies. Some do this check only after the user's
  get_format callback returns.)
- The hw_pix_fmt must be one of the choices suggested by get_format. If the
  user decides to use a AVHWFramesContext prepared with this API function,
  the user must return the same hw_pix_fmt from get_format.
- The device_ref passed to this function must support the given hw_pix_fmt.
- After calling this API function, it is the user's responsibility to
  initialize the AVHWFramesContext (returned by the out_frames_ref parameter),
  and to set AVCodecContext.hw_frames_ctx to it. If done, this must be done
  before returning from get_format (this is implied by the normal
  AVCodecContext.hw_frames_ctx API rules).
- The AVHWFramesContext parameters may change every time time get_format is
  called. Also, AVCodecContext.hw_frames_ctx is reset before get_format. So
  you are inherently required to go through this process again on every
  get_format call.
- It is perfectly possible to call this function without actually using
  the resulting AVHWFramesContext. One use-case might be trying to reuse a
  previously initialized AVHWFramesContext, and calling this API function
  only to test whether the required frame parameters have changed.
- Fields that use dynamically allocated values of any kind must not be set
  by the user unless setting them is explicitly allowed by the documentation.
  If the user sets AVHWFramesContext.free and AVHWFramesContext.user_opaque,
  the new free callback must call the potentially set previous free callback.
  This API call may set any dynamically allocated fields, including the free
  callback.

The function will set at least the following fields on AVHWFramesContext
(potentially more, depending on hwaccel API):

- All fields set by av_hwframe_ctx_alloc().
- Set the format field to hw_pix_fmt.
- Set the sw_format field to the most suited and most versatile format. (An
  implication is that this will prefer generic formats over opaque formats
  with arbitrary restrictions, if possible.)
- Set the width/height fields to the coded frame size, rounded up to the
  API-specific minimum alignment.
- Only _if_ the hwaccel requires a pre-allocated pool: set the initial_pool_size
  field to the number of maximum reference surfaces possible with the codec,
  plus 1 surface for the user to work (meaning the user can safely reference
  at most 1 decoded surface at a time), plus additional buffering introduced
  by frame threading. If the hwaccel does not require pre-allocation, the
  field is left to 0, and the decoder will allocate new surfaces on demand
  during decoding.
- Possibly AVHWFramesContext.hwctx fields, depending on the underlying
  hardware API.

Essentially, out_frames_ref returns the same as av_hwframe_ctx_alloc(), but
with basic frame parameters set.

The function is stateless, and does not change the AVCodecContext or the
device_ref AVHWDeviceContext.

@param avctx The context which is currently calling get_format, and which
             implicitly contains all state needed for filling the returned
             AVHWFramesContext properly.
@param device_ref A reference to the AVHWDeviceContext describing the device
                  which will be used by the hardware decoder.
@param hw_pix_fmt The hwaccel format you are going to return from get_format.
@param out_frames_ref On success, set to a reference to an _uninitialized_
                      AVHWFramesContext, created from the given device_ref.
                      Fields will be set to values required for decoding.
                      Not changed if an error is returned.
@return zero on success, a negative value on error. The following error codes
        have special semantics:
     AVERROR(ENOENT): the decoder does not support this functionality. Setup
                      is always manual, or it is a decoder which does not
                      support setting AVCodecContext.hw_frames_ctx at all,
                      or it is a software format.
     AVERROR(EINVAL): it is known that hardware decoding is not supported for
                      this configuration, or the device_ref is not supported
                      for the hwaccel referenced by hw_pix_fmt.

func AVCodecGetTag ¶

func AVCodecGetTag(tags **AVCodecTag, id AVCodecID) uint

AVCodecGetTag wraps av_codec_get_tag.

Get the codec tag for the given codec id id.
If no codec tag is found returns 0.

@param tags list of supported codec_id-codec_tag pairs, as stored
in AVInputFormat.codec_tag and AVOutputFormat.codec_tag
@param id   codec ID to match to a codec tag

func AVCodecIsDecoder ¶

func AVCodecIsDecoder(codec *AVCodec) (int, error)

AVCodecIsDecoder wraps av_codec_is_decoder.

@return a non-zero number if codec is a decoder, zero otherwise

func AVCodecIsEncoder ¶

func AVCodecIsEncoder(codec *AVCodec) (int, error)

AVCodecIsEncoder wraps av_codec_is_encoder.

@return a non-zero number if codec is an encoder, zero otherwise

func AVCodecIsOpen ¶

func AVCodecIsOpen(s *AVCodecContext) (int, error)

AVCodecIsOpen wraps avcodec_is_open.

@return a positive value if s is open (i.e. avcodec_open2() was called on it),
0 otherwise.

func AVCodecOpen2 ¶

func AVCodecOpen2(avctx *AVCodecContext, codec *AVCodec, options **AVDictionary) (int, error)

AVCodecOpen2 wraps avcodec_open2.

Initialize the AVCodecContext to use the given AVCodec. Prior to using this
function the context has to be allocated with avcodec_alloc_context3().

The functions avcodec_find_decoder_by_name(), avcodec_find_encoder_by_name(),
avcodec_find_decoder() and avcodec_find_encoder() provide an easy way for
retrieving a codec.

Depending on the codec, you might need to set options in the codec context
also for decoding (e.g. width, height, or the pixel or audio sample format in
the case the information is not available in the bitstream, as when decoding
raw audio or video).

Options in the codec context can be set either by setting them in the options
AVDictionary, or by setting the values in the context itself, directly or by
using the av_opt_set() API before calling this function.

Example:
@code
av_dict_set(&opts, "b", "2.5M", 0);
codec = avcodec_find_decoder(AV_CODEC_ID_H264);
if (!codec)
    exit(1);

context = avcodec_alloc_context3(codec);

if (avcodec_open2(context, codec, opts) < 0)
    exit(1);
@endcode

In the case AVCodecParameters are available (e.g. when demuxing a stream
using libavformat, and accessing the AVStream contained in the demuxer), the
codec parameters can be copied to the codec context using
avcodec_parameters_to_context(), as in the following example:

@code
AVStream *stream = ...;
context = avcodec_alloc_context3(codec);
if (avcodec_parameters_to_context(context, stream->codecpar) < 0)
    exit(1);
if (avcodec_open2(context, codec, NULL) < 0)

func AVCodecReceiveFrame ¶

func AVCodecReceiveFrame(avctx *AVCodecContext, frame *AVFrame) (int, error)

AVCodecReceiveFrame wraps avcodec_receive_frame.

Return decoded output data from a decoder or encoder (when the
@ref AV_CODEC_FLAG_RECON_FRAME flag is used).

@param avctx codec context
@param frame This will be set to a reference-counted video or audio
             frame (depending on the decoder type) allocated by the
             codec. Note that the function will always call
             av_frame_unref(frame) before doing anything else.

@retval 0                success, a frame was returned
@retval AVERROR(EAGAIN)  output is not available in this state - user must
                         try to send new input
@retval AVERROR_EOF      the codec has been fully flushed, and there will be
                         no more output frames
@retval AVERROR(EINVAL)  codec not opened, or it is an encoder without the
                         @ref AV_CODEC_FLAG_RECON_FRAME flag enabled
@retval "other negative error code" legitimate decoding errors

func AVCodecReceivePacket ¶

func AVCodecReceivePacket(avctx *AVCodecContext, avpkt *AVPacket) (int, error)

AVCodecReceivePacket wraps avcodec_receive_packet.

Read encoded data from the encoder.

@param avctx codec context
@param avpkt This will be set to a reference-counted packet allocated by the
             encoder. Note that the function will always call
             av_packet_unref(avpkt) before doing anything else.
@retval 0               success
@retval AVERROR(EAGAIN) output is not available in the current state - user must
                        try to send input
@retval AVERROR_EOF     the encoder has been fully flushed, and there will be no
                        more output packets
@retval AVERROR(EINVAL) codec not opened, or it is a decoder
@retval "another negative error code" legitimate encoding errors

func AVCodecSendFrame ¶

func AVCodecSendFrame(avctx *AVCodecContext, frame *AVFrame) (int, error)

AVCodecSendFrame wraps avcodec_send_frame.

Supply a raw video or audio frame to the encoder. Use avcodec_receive_packet()
to retrieve buffered output packets.

@param avctx     codec context
@param[in] frame AVFrame containing the raw audio or video frame to be encoded.
                 Ownership of the frame remains with the caller, and the
                 encoder will not write to the frame. The encoder may create
                 a reference to the frame data (or copy it if the frame is
                 not reference-counted).
                 It can be NULL, in which case it is considered a flush
                 packet.  This signals the end of the stream. If the encoder
                 still has packets buffered, it will return them after this
                 call. Once flushing mode has been entered, additional flush
                 packets are ignored, and sending frames will return
                 AVERROR_EOF.

                 For audio:
                 If AV_CODEC_CAP_VARIABLE_FRAME_SIZE is set, then each frame
                 can have any number of samples.
                 If it is not set, frame->nb_samples must be equal to
                 avctx->frame_size for all frames except the last.
                 The final frame may be smaller than avctx->frame_size.
@retval 0                 success
@retval AVERROR(EAGAIN)   input is not accepted in the current state - user must
                          read output with avcodec_receive_packet() (once all
                          output is read, the packet should be resent, and the
                          call will not fail with EAGAIN).
@retval AVERROR_EOF       the encoder has been flushed, and no new frames can
                          be sent to it
@retval AVERROR(EINVAL)   codec not opened, it is a decoder, or requires flush
@retval AVERROR(ENOMEM)   failed to add packet to internal queue, or similar
@retval "another negative error code" legitimate encoding errors

func AVCodecSendPacket ¶

func AVCodecSendPacket(avctx *AVCodecContext, avpkt *AVPacket) (int, error)

AVCodecSendPacket wraps avcodec_send_packet.

Supply raw packet data as input to a decoder.

Internally, this call will copy relevant AVCodecContext fields, which can
influence decoding per-packet, and apply them when the packet is actually
decoded. (For example AVCodecContext.skip_frame, which might direct the
decoder to drop the frame contained by the packet sent with this function.)

@warning The input buffer, avpkt->data must be AV_INPUT_BUFFER_PADDING_SIZE
         larger than the actual read bytes because some optimized bitstream
         readers read 32 or 64 bits at once and could read over the end.

@note The AVCodecContext MUST have been opened with @ref avcodec_open2()
      before packets may be fed to the decoder.

@param avctx codec context
@param[in] avpkt The input AVPacket. Usually, this will be a single video
                 frame, or several complete audio frames.
                 Ownership of the packet remains with the caller, and the
                 decoder will not write to the packet. The decoder may create
                 a reference to the packet data (or copy it if the packet is
                 not reference-counted).
                 Unlike with older APIs, the packet is always fully consumed,
                 and if it contains multiple frames (e.g. some audio codecs),
                 will require you to call avcodec_receive_frame() multiple
                 times afterwards before you can send a new packet.
                 It can be NULL (or an AVPacket with data set to NULL and
                 size set to 0); in this case, it is considered a flush
                 packet, which signals the end of the stream. Sending the
                 first flush packet will return success. Subsequent ones are
                 unnecessary and will return AVERROR_EOF. If the decoder
                 still has frames buffered, it will return them after sending
                 a flush packet.

@retval 0                 success
@retval AVERROR(EAGAIN)   input is not accepted in the current state - user
                          must read output with avcodec_receive_frame() (once
                          all output is read, the packet should be resent,
                          and the call will not fail with EAGAIN).
@retval AVERROR_EOF       the decoder has been flushed, and no new packets can be
                          sent to it (also returned if more than 1 flush
                          packet is sent)
@retval AVERROR(EINVAL)   codec not opened, it is an encoder, or requires flush
@retval AVERROR(ENOMEM)   failed to add packet to internal queue, or similar
@retval "another negative error code" legitimate decoding errors

In other words, compare the least significant `log2(mod)` bits of integers
`a` and `b`.

av_compare_mod(0x11, 0x02, 0x20) > 0 // since 0x11 % 0x20 (0x11) > 0x02 % 0x20 (0x02)

country code, terminal provider codes, and application identifier.
@param s A pointer containing the decoded AVDynamicHDRPlus structure.
@param data The byte array containing the raw ITU-T T.35 data.
@param size Size of the data array in bytes.

@return >= 0 on success. Otherwise, returns the appropriate AVERROR.

func AVDynarrayAdd ¶

func AVDynarrayAdd(tabPtr unsafe.Pointer, nbPtr *int, elem unsafe.Pointer)

AVDynarrayAdd wraps av_dynarray_add.

Add the pointer to an element to a dynamic array.

The array to grow is supposed to be an array of pointers to
structures, and the element to add must be a pointer to an already
allocated structure.

The array is reallocated when its size reaches powers of 2.
Therefore, the amortized cost of adding an element is constant.

In case of success, the pointer to the array is updated in order to
point to the new grown array, and the number pointed to by `nb_ptr`
is incremented.
In case of failure, the array is freed, `*tab_ptr` is set to `NULL` and
`*nb_ptr` is set to 0.

@param[in,out] tab_ptr Pointer to the array to grow
@param[in,out] nb_ptr  Pointer to the number of elements in the array
@param[in]     elem    Element to add

but it doesn't free memory on fails. It returns error code
instead and leave current buffer untouched.

@return >=0 on success, negative otherwise
@see av_dynarray_add(), av_dynarray2_add()

func AVEncryptionInfoAddSideData(info *AVEncryptionInfo, sideDataSize *uint64) unsafe.Pointer

AVEncryptionInfoAddSideData wraps av_encryption_info_add_side_data.

Allocates and initializes side data that holds a copy of the given encryption
info.  The resulting pointer should be either freed using av_free or given

@return The new side-data pointer, or NULL.

func AVEncryptionInfoFree ¶

func AVEncryptionInfoFree(info *AVEncryptionInfo)

AVEncryptionInfoFree wraps av_encryption_info_free.

in a parsed expression.

@param e the AVExpr to track user provided functions in
@param counter a zero-initialized array where the count of each function will be stored
               if you passed 5 functions with 2 arguments to av_expr_parse()
               then for arg=2 this will use up to 5 entries.
@param size size of array
@param arg number of arguments the counted functions have
@return 0 on success, a negative value indicates that no expression or array was passed
or size was zero

func AVExprCountVars ¶

func AVFastMalloc ¶

func AVFastMalloc(ptr unsafe.Pointer, size *uint, minSize uint64)

AVFastMalloc wraps av_fast_malloc.

Allocate a buffer, reusing the given one if large enough.

Contrary to av_fast_realloc(), the current buffer contents might not be
preserved and on error the old buffer is freed, thus no special handling to
avoid memleaks is necessary.

`*ptr` is allowed to be `NULL`, in which case allocation always happens if
`size_needed` is greater than 0.

@code{.c}
uint8_t *buf = ...;
av_fast_malloc(&buf, &current_size, size_needed);
if (!buf) {
    // Allocation failed; buf already freed
    return AVERROR(ENOMEM);
}
@endcode

@param[in,out] ptr      Pointer to pointer to an already allocated buffer.
                        `*ptr` will be overwritten with pointer to new
                        buffer on success or `NULL` on failure
@param[in,out] size     Pointer to the size of buffer `*ptr`. `*size` is
                        updated to the new allocated size, in particular 0

`size_needed` is greater than 0.

@param[in,out] ptr      Pointer to pointer to an already allocated buffer.
                        `*ptr` will be overwritten with pointer to new
                        buffer on success or `NULL` on failure
@param[in,out] size     Pointer to the size of buffer `*ptr`. `*size` is
                        updated to the new allocated size, in particular 0
                        in case of failure.
@param[in]     min_size Desired minimal size of buffer `*ptr`
@see av_fast_malloc()

func AVFastPaddedMalloc ¶

func AVFastPaddedMalloc(ptr unsafe.Pointer, size *uint, minSize uint64)

AVFastPaddedMalloc wraps av_fast_padded_malloc.

Same behaviour av_fast_malloc but the buffer has additional
AV_INPUT_BUFFER_PADDING_SIZE at the end which will always be 0.

In addition the whole buffer will initially and after resizes
be 0-initialized so that no uninitialized data will ever appear.

func AVFastPaddedMallocz ¶

func AVFastPaddedMallocz(ptr unsafe.Pointer, size *uint, minSize uint64)

AVFastPaddedMallocz wraps av_fast_padded_mallocz.

Same behaviour av_fast_padded_malloc except that buffer will always

func AVFastRealloc ¶

func AVFastRealloc(ptr unsafe.Pointer, size *uint, minSize uint64) unsafe.Pointer

AVFastRealloc wraps av_fast_realloc.

Reallocate the given buffer if it is not large enough, otherwise do nothing.

If the given buffer is `NULL`, then a new uninitialized buffer is allocated.

If the given buffer is not large enough, and reallocation fails, `NULL` is
returned and `*size` is set to 0, but the original buffer is not changed or
freed.

A typical use pattern follows:

@code{.c}
uint8_t *buf = ...;
uint8_t *new_buf = av_fast_realloc(buf, &current_size, size_needed);
if (!new_buf) {
    // Allocation failed; clean up original buffer
    av_freep(&buf);
    return AVERROR(ENOMEM);
}
@endcode

@param[in,out] ptr      Already allocated buffer, or `NULL`
@param[in,out] size     Pointer to the size of buffer `ptr`. `*size` is
                        updated to the new allocated size, in particular 0
                        in case of failure.
@param[in]     min_size Desired minimal size of buffer `ptr`
@return `ptr` if the buffer is large enough, a pointer to newly reallocated
        buffer if the buffer was not large enough, or `NULL` in case of
        error
@see av_realloc()
@see av_fast_malloc()

        into the FIFO. More data may be written when the
        AV_FIFO_FLAG_AUTO_GROW flag was specified at FIFO creation, but this
        may involve memory allocation, which can fail.

In case nb_elems > av_fifo_can_write(f) and the AV_FIFO_FLAG_AUTO_GROW flag
was not specified at FIFO creation, nothing is written and an error
is returned.

Calling function is guaranteed to succeed if nb_elems <= av_fifo_can_write(f).

@param f the FIFO buffer
@param buf Data to be written. nb_elems * av_fifo_elem_size(f) bytes will be
           read from buf on success.

AVFilterFilterPadCount wraps avfilter_filter_pad_count.

Get the number of elements in an AVFilter's inputs or outputs array.

func AVFilterFree ¶

func AVFilterFree(filter *AVFilterContext)

@return >= 0 in case of success, a negative AVERROR code otherwise

func AVFilterGraphCreateFilter ¶

func AVFilterGraphCreateFilter(filtCtx **AVFilterContext, filt *AVFilter, name *CStr, args *CStr, opaque unsafe.Pointer, graphCtx *AVFilterGraph) (int, error)

AVFilterGraphCreateFilter wraps avfilter_graph_create_filter.

A convenience wrapper that allocates and initializes a filter in a single
step. The filter instance is created from the filter filt and inited with the
parameter args. opaque is currently ignored.

In case of success put in *filt_ctx the pointer to the created
filter instance, otherwise set *filt_ctx to NULL.

@param name the instance name to give to the created filter instance
@param graph_ctx the filter graph
@return a negative AVERROR error code in case of failure, a non
negative value otherwise

@warning Since the filter is initialized after this function successfully
         returns, you MUST NOT set any further options on it. If you need to
         do that, call ::avfilter_graph_alloc_filter(), followed by setting
         the options, followed by ::avfilter_init_dict() instead of this
         function.

func AVFilterGraphFree ¶

func AVFilterGraphFree(graph **AVFilterGraph)

AVFilterGraphFree wraps avfilter_graph_free.

Free a graph, destroy its links, and set *graph to NULL.
If *graph is NULL, do nothing.

func AVFilterGraphParse ¶

func AVFilterGraphParse(graph *AVFilterGraph, filters *CStr, inputs *AVFilterInOut, outputs *AVFilterInOut, logCtx unsafe.Pointer) (int, error)

AVFilterGraphParse wraps avfilter_graph_parse.

Add a graph described by a string to a graph.

@note The caller must provide the lists of inputs and outputs,
which therefore must be known before calling the function.

@note The inputs parameter describes inputs of the already existing
part of the graph; i.e. from the point of view of the newly created
part, they are outputs. Similarly the outputs parameter describes
outputs of the already existing filters, which are provided as
inputs to the parsed filters.

@param graph   the filter graph where to link the parsed graph context
@param filters string to be parsed
@param inputs  linked list to the inputs of the graph
@param outputs linked list to the outputs of the graph
@return zero on success, a negative AVERROR code on error

func AVFilterGraphParse2 ¶

@param[in]  filters string to be parsed
@param[out] inputs  a linked list of all free (unlinked) inputs of the
                    parsed graph will be returned here. It is to be freed
                    by the caller using avfilter_inout_free().
@param[out] outputs a linked list of all free (unlinked) outputs of the
                    parsed graph will be returned here. It is to be freed by the
                    caller using avfilter_inout_free().
@return zero on success, a negative AVERROR code on error

@note This function returns the inputs and outputs that are left
unlinked after parsing the graph and the caller then deals with
them.
@note This function makes no reference whatsoever to already
existing parts of the graph and the inputs parameter will on return
contain inputs of the newly parsed part of the graph.  Analogously
the outputs parameter will contain outputs of the newly created
filters.

func AVFilterGraphParsePtr ¶

func AVFilterGraphParsePtr(graph *AVFilterGraph, filters *CStr, inputs **AVFilterInOut, outputs **AVFilterInOut, logCtx unsafe.Pointer) (int, error)

AVFilterGraphParsePtr wraps avfilter_graph_parse_ptr.

Add a graph described by a string to a graph.

In the graph filters description, if the input label of the first
filter is not specified, "in" is assumed; if the output label of
the last filter is not specified, "out" is assumed.

@param graph   the filter graph where to link the parsed graph context
@param filters string to be parsed
@param inputs  pointer to a linked list to the inputs of the graph, may be NULL.
               If non-NULL, *inputs is updated to contain the list of open inputs
               after the parsing, should be freed with avfilter_inout_free().
@param outputs pointer to a linked list to the outputs of the graph, may be NULL.
               If non-NULL, *outputs is updated to contain the list of open outputs
               after the parsing, should be freed with avfilter_inout_free().
@return non negative on success, a negative AVERROR code on error

func AVFilterGraphQueueCommand ¶

func AVFilterGraphQueueCommand(graph *AVFilterGraph, target *CStr, cmd *CStr, arg *CStr, flags int, ts float64) (int, error)

AVFilterGraphQueueCommand wraps avfilter_graph_queue_command.

Queue a command for one or more filter instances.

@param graph  the filter graph
@param target the filter(s) to which the command should be sent
              "all" sends to all filters
              otherwise it can be a filter or filter instance name
              which will send the command to all matching filters.
@param cmd    the command to sent, for handling simplicity all commands must be alphanumeric only
@param arg    the argument for the command
@param ts     time at which the command should be sent to the filter

@note As this executes commands after this function returns, no return code
      from the filter is provided, also AVFILTER_CMD_FLAG_ONE is not supported.

func AVFilterGraphRequestOldest ¶

func AVFilterGraphRequestOldest(graph *AVFilterGraph) (int, error)

AVFilterGraphRequestOldest wraps avfilter_graph_request_oldest.

Request a frame on the oldest sink link.

If the request returns AVERROR_EOF, try the next.

Note that this function is not meant to be the sole scheduling mechanism
of a filtergraph, only a convenience function to help drain a filtergraph
in a balanced way under normal circumstances.

Also note that AVERROR_EOF does not mean that frames did not arrive on
some of the sinks during the process.
When there are multiple sink links, in case the requested link
returns an EOF, this may cause a filter to flush pending frames
which are sent to another sink link, although unrequested.

@return  the return value of ff_request_frame(),
         or AVERROR_EOF if all links returned AVERROR_EOF

func AVFilterGraphSegmentApply ¶

func AVFilterGraphSegmentApply(seg *AVFilterGraphSegment, flags int, inputs **AVFilterInOut, outputs **AVFilterInOut) (int, error)

AVFilterGraphSegmentApply wraps avfilter_graph_segment_apply.

Apply all filter/link descriptions from a graph segment to the associated filtergraph.

This functions is currently equivalent to calling the following in sequence:
- avfilter_graph_segment_create_filters();
- avfilter_graph_segment_apply_opts();
- avfilter_graph_segment_init();
- avfilter_graph_segment_link();
failing if any of them fails. This list may be extended in the future.

Since the above functions are idempotent, the caller may call some of them
manually, then do some custom processing on the filtergraph, then call this
function to do the rest.

@param seg the filtergraph segment to process
@param flags reserved for future use, caller must set to 0 for now
@param[out] inputs passed to avfilter_graph_segment_link()
@param[out] outputs passed to avfilter_graph_segment_link()

@retval "non-negative number" success
@retval "negative error code" failure

@note Calling this function multiple times is safe, as it is idempotent.

func AVFilterGraphSegmentApplyOpts ¶

func AVFilterGraphSegmentApplyOpts(seg *AVFilterGraphSegment, flags int) (int, error)

AVFilterGraphSegmentApplyOpts wraps avfilter_graph_segment_apply_opts.

Apply parsed options to filter instances in a graph segment.

Walk through all filter instances in the graph segment that have option
dictionaries associated with them and apply those options with
av_opt_set_dict2(..., AV_OPT_SEARCH_CHILDREN). AVFilterParams.opts is
replaced by the dictionary output by av_opt_set_dict2(), which should be
empty (NULL) if all options were successfully applied.

If any options could not be found, this function will continue processing all
other filters and finally return AVERROR_OPTION_NOT_FOUND (unless another
error happens). The calling program may then deal with unapplied options as
it wishes.

Any creation-pending filters (see avfilter_graph_segment_create_filters())
present in the segment will cause this function to fail. AVFilterParams with
no associated filter context are simply skipped.

@param seg the filtergraph segment to process
@param flags reserved for future use, caller must set to 0 for now

@retval "non-negative number" Success, all options were successfully applied.
@retval AVERROR_OPTION_NOT_FOUND some options were not found in a filter
@retval "another negative error code" other failures

@note Calling this function multiple times is safe, as it is idempotent.

func AVFilterGraphSegmentCreateFilters ¶

func AVFilterGraphSegmentCreateFilters(seg *AVFilterGraphSegment, flags int) (int, error)

AVFilterGraphSegmentCreateFilters wraps avfilter_graph_segment_create_filters.

Create filters specified in a graph segment.

Walk through the creation-pending AVFilterParams in the segment and create
new filter instances for them.
Creation-pending params are those where AVFilterParams.filter_name is
non-NULL (and hence AVFilterParams.filter is NULL). All other AVFilterParams
instances are ignored.

For any filter created by this function, the corresponding
AVFilterParams.filter is set to the newly-created filter context,
AVFilterParams.filter_name and AVFilterParams.instance_name are freed and set
to NULL.

@param seg the filtergraph segment to process
@param flags reserved for future use, caller must set to 0 for now

@retval "non-negative number" Success, all creation-pending filters were
                              successfully created
@retval AVERROR_FILTER_NOT_FOUND some filter's name did not correspond to a
                                 known filter
@retval "another negative error code" other failures

@note Calling this function multiple times is safe, as it is idempotent.

func AVFilterGraphSegmentFree ¶

func AVFilterGraphSegmentFree(seg **AVFilterGraphSegment)

AVFilterGraphSegmentFree wraps avfilter_graph_segment_free.

Free the provided AVFilterGraphSegment and everything associated with it.

@param seg double pointer to the AVFilterGraphSegment to be freed. NULL will
be written to this pointer on exit from this function.

@note
The filter contexts (AVFilterParams.filter) are owned by AVFilterGraph rather
than AVFilterGraphSegment, so they are not freed.

func AVFilterGraphSegmentInit ¶

func AVFilterGraphSegmentInit(seg *AVFilterGraphSegment, flags int) (int, error)

AVFilterGraphSegmentInit wraps avfilter_graph_segment_init.

Initialize all filter instances in a graph segment.

Walk through all filter instances in the graph segment and call
avfilter_init_dict(..., NULL) on those that have not been initialized yet.

Any creation-pending filters (see avfilter_graph_segment_create_filters())
present in the segment will cause this function to fail. AVFilterParams with
no associated filter context or whose filter context is already initialized,
are simply skipped.

@param seg the filtergraph segment to process
@param flags reserved for future use, caller must set to 0 for now

@retval "non-negative number" Success, all filter instances were successfully
                              initialized
@retval "negative error code" failure

@note Calling this function multiple times is safe, as it is idempotent.

func AVFilterGraphSegmentLink ¶

func AVFilterGraphSegmentLink(seg *AVFilterGraphSegment, flags int, inputs **AVFilterInOut, outputs **AVFilterInOut) (int, error)

AVFilterGraphSegmentLink wraps avfilter_graph_segment_link.

Link filters in a graph segment.

Walk through all filter instances in the graph segment and try to link all
unlinked input and output pads. Any creation-pending filters (see
avfilter_graph_segment_create_filters()) present in the segment will cause
this function to fail. Disabled filters and already linked pads are skipped.

Every filter output pad that has a corresponding AVFilterPadParams with a
non-NULL label is
- linked to the input with the matching label, if one exists;
- exported in the outputs linked list otherwise, with the label preserved.
Unlabeled outputs are
- linked to the first unlinked unlabeled input in the next non-disabled
  filter in the chain, if one exists
- exported in the outputs linked list otherwise, with NULL label

Similarly, unlinked input pads are exported in the inputs linked list.

@param seg the filtergraph segment to process
@param flags reserved for future use, caller must set to 0 for now
@param[out] inputs  a linked list of all free (unlinked) inputs of the
                    filters in this graph segment will be returned here. It
                    is to be freed by the caller using avfilter_inout_free().
@param[out] outputs a linked list of all free (unlinked) outputs of the
                    filters in this graph segment will be returned here. It
                    is to be freed by the caller using avfilter_inout_free().

@retval "non-negative number" success
@retval "negative error code" failure

@note Calling this function multiple times is safe, as it is idempotent.

func AVFilterGraphSegmentParse ¶

func AVFilterGraphSegmentParse(graph *AVFilterGraph, graphStr *CStr, flags int, seg **AVFilterGraphSegment) (int, error)

AVFilterGraphSegmentParse wraps avfilter_graph_segment_parse.

Parse a textual filtergraph description into an intermediate form.

This intermediate representation is intended to be modified by the caller as
described in the documentation of AVFilterGraphSegment and its children, and
then applied to the graph either manually or with other
avfilter_graph_segment_*() functions. See the documentation for
avfilter_graph_segment_apply() for the canonical way to apply
AVFilterGraphSegment.

@param graph Filter graph the parsed segment is associated with. Will only be
             used for logging and similar auxiliary purposes. The graph will
             not be actually modified by this function - the parsing results
             are instead stored in seg for further processing.
@param graph_str a string describing the filtergraph segment
@param flags reserved for future use, caller must set to 0 for now
@param seg A pointer to the newly-created AVFilterGraphSegment is written
           here on success. The graph segment is owned by the caller and must
           be freed with avfilter_graph_segment_free() before graph itself is
           freed.

@retval "non-negative number" success
@retval "negative error code" failure

func AVFilterGraphSendCommand ¶

func AVFilterGraphSendCommand(graph *AVFilterGraph, target *CStr, cmd *CStr, arg *CStr, res *CStr, resLen int, flags int) (int, error)

AVFilterGraphSendCommand wraps avfilter_graph_send_command.

Send a command to one or more filter instances.

@param graph  the filter graph
@param target the filter(s) to which the command should be sent
              "all" sends to all filters
              otherwise it can be a filter or filter instance name
              which will send the command to all matching filters.
@param cmd    the command to send, for handling simplicity all commands must be alphanumeric only
@param arg    the argument for the command
@param res    a buffer with size res_size where the filter(s) can return a response.

@returns >=0 on success otherwise an error code.
             AVERROR(ENOSYS) on unsupported commands

func AVFilterGraphSetAutoConvert ¶

func AVFilterGraphSetAutoConvert(graph *AVFilterGraph, flags uint)

AVFilterInitDict wraps avfilter_init_dict.

Initialize a filter with the supplied dictionary of options.

@param ctx     uninitialized filter context to initialize
@param options An AVDictionary filled with options for this filter. On
               return this parameter will be destroyed and replaced with
               a dict containing options that were not found. This dictionary
               must be freed by the caller.
               May be NULL, then this function is equivalent to
               avfilter_init_str() with the second parameter set to NULL.
@return 0 on success, a negative AVERROR on failure

@note This function and avfilter_init_str() do essentially the same thing,
the difference is in manner in which the options are passed. It is up to the
calling code to choose whichever is more preferable. The two functions also
behave differently when some of the provided options are not declared as
supported by the filter. In such a case, avfilter_init_str() will fail, but
this function will leave those extra options in the options AVDictionary and
continue as usual.

func AVFilterInitStr ¶

func AVFilterInitStr(ctx *AVFilterContext, args *CStr) (int, error)

AVFilterInitStr wraps avfilter_init_str.

Initialize a filter with the supplied parameters.

@param ctx  uninitialized filter context to initialize
@param args Options to initialize the filter with. This must be a
            ':'-separated list of options in the 'key=value' form.
            May be NULL if the options have been set directly using the
            AVOptions API or there are no options that need to be set.
@return 0 on success, a negative AVERROR on failure

func AVFilterInoutFree ¶

func AVFilterInoutFree(inout **AVFilterInOut)

AVFilterInoutFree wraps avfilter_inout_free.

Free the supplied list of AVFilterInOut and set *inout to NULL.
If *inout is NULL, do nothing.

AVFindBestStream wraps av_find_best_stream.

Find the "best" stream in the file.
The best stream is determined according to various heuristics as the most
likely to be what the user expects.
If the decoder parameter is non-NULL, av_find_best_stream will find the
default decoder for the stream's codec; streams for which no decoder can
be found are ignored.

@param ic                media file handle
@param type              stream type: video, audio, subtitles, etc.
@param wanted_stream_nb  user-requested stream number,
                         or -1 for automatic selection
@param related_stream    try to find a stream related (eg. in the same
                         program) to this one, or -1 if none
@param decoder_ret       if non-NULL, returns the decoder for the
                         selected stream
@param flags             flags; none are currently defined

@return  the non-negative stream number in case of success,
         AVERROR_STREAM_NOT_FOUND if no stream with the requested type
         could be found,
         AVERROR_DECODER_NOT_FOUND if streams were found but no decoder

@note  If av_find_best_stream returns successfully and decoder_ret is not
       NULL, then *decoder_ret is guaranteed to be set to a valid AVCodec.

func AVFindDefaultStreamIndex ¶

func AVFindDefaultStreamIndex(s *AVFormatContext) (int, error)

AVFindDefaultStreamIndex wraps av_find_default_stream_index.

func AVFindInfoTag ¶

AVFormatAllocOutputContext2 wraps avformat_alloc_output_context2.

Allocate an AVFormatContext for an output format.
avformat_free_context() can be used to free the context and
everything allocated by the framework within it.

@param ctx           pointee is set to the created format context,
                     or to NULL in case of failure
@param oformat       format to use for allocating the context, if NULL
                     format_name and filename are used instead
@param format_name   the name of output format to use for allocating the
                     context, if NULL filename is used instead
@param filename      the name of the filename to use for allocating the
                     context, may be NULL

func AVFormatFindStreamInfo ¶

func AVFormatFindStreamInfo(ic *AVFormatContext, options **AVDictionary) (int, error)

AVFormatFindStreamInfo wraps avformat_find_stream_info.

Read packets of a media file to get stream information. This
is useful for file formats with no headers such as MPEG. This
function also computes the real framerate in case of MPEG-2 repeat
frame mode.
The logical file position is not changed by this function;
examined packets may be buffered for later processing.

@param ic media file handle
@param options  If non-NULL, an ic.nb_streams long array of pointers to
                dictionaries, where i-th member contains options for
                codec corresponding to i-th stream.
                On return each dictionary will be filled with options that were not found.
@return >=0 if OK, AVERROR_xxx on error

@note this function isn't guaranteed to open all the codecs, so
      options being non-empty at return is a perfectly normal behavior.

@todo Let the user decide somehow what information is needed so that
      we do not waste time getting stuff the user does not need.

func AVFormatFlush ¶

func AVFormatFlush(s *AVFormatContext) (int, error)

AVFormatFlush wraps avformat_flush.

Discard all internally buffered data. This can be useful when dealing with
discontinuities in the byte stream. Generally works only with formats that
can resync. This includes headerless formats like MPEG-TS/TS but should also
work with NUT, Ogg and in a limited way AVI for example.

The set of streams, the detected duration, stream parameters and codecs do
not change when calling this function. If you want a complete reset, it's
better to open a new AVFormatContext.

This does not flush the AVIOContext (s->pb). If necessary, call
avio_flush(s->pb) before calling this function.

@param s media file handle
@return >=0 on success, error code otherwise

func AVFormatInitOutput ¶

func AVFormatInitOutput(s *AVFormatContext, options **AVDictionary) (int, error)

AVFormatInitOutput wraps avformat_init_output.

Allocate the stream private data and initialize the codec, but do not write the header.
May optionally be used before avformat_write_header() to initialize stream parameters
before actually writing the header.
If using this function, do not pass the same options to avformat_write_header().

@param s        Media file handle, must be allocated with
                avformat_alloc_context().
                Its \ref AVFormatContext.oformat "oformat" field must be set
                to the desired output format;
                Its \ref AVFormatContext.pb "pb" field must be set to an
                already opened ::AVIOContext.
@param options  An ::AVDictionary filled with AVFormatContext and
                muxer-private options.
                On return this parameter will be destroyed and replaced with
                a dict containing options that were not found. May be NULL.

@retval AVSTREAM_INIT_IN_WRITE_HEADER On success, if the codec requires
                                      avformat_write_header to fully initialize.
@retval AVSTREAM_INIT_IN_INIT_OUTPUT  On success, if the codec has been fully
                                      initialized.
@retval AVERROR                       Anegative AVERROR on failure.

spec.

See the "stream specifiers" chapter in the documentation for the syntax
of spec.

@return  >0 if st is matched by spec;
         0  if st is not matched by spec;
         AVERROR code if spec is invalid

@note  A stream specifier can match several streams in the format.

func AVFormatNetworkDeinit ¶

once for each time you called avformat_network_init.

func AVFormatNetworkInit ¶

func AVFormatNetworkInit() (int, error)

AVFormatNetworkInit wraps avformat_network_init.

Do global initialization of network libraries. This is optional,
and not recommended anymore.

This functions only exists to work around thread-safety issues
with older GnuTLS or OpenSSL libraries. If libavformat is linked
to newer versions of those libraries, or if you do not use them,
calling this function is unnecessary. Otherwise, you need to call
this function before any other threads using them are started.

This function will be deprecated once support for older GnuTLS and
OpenSSL libraries is removed, and this function has no purpose
anymore.

func AVFormatOpenInput ¶

func AVFormatOpenInput(ps **AVFormatContext, url *CStr, fmt *AVInputFormat, options **AVDictionary) (int, error)

AVFormatOpenInput wraps avformat_open_input.

The stream must be closed with avformat_close_input().

@param ps       Pointer to user-supplied AVFormatContext (allocated by
                avformat_alloc_context). May be a pointer to NULL, in
                which case an AVFormatContext is allocated by this
                function and written into ps.
                Note that a user-supplied AVFormatContext will be freed
                on failure and its pointer set to NULL.
@param url      URL of the stream to open.
@param fmt      If non-NULL, this parameter forces a specific input format.
                Otherwise the format is autodetected.
@param options  A dictionary filled with AVFormatContext and demuxer-private
                options.
                On return this parameter will be destroyed and replaced with
                a dict containing options that were not found. May be NULL.

@return 0 on success; on failure: frees ps, sets its pointer to NULL,
        and returns a negative AVERROR.

@note If you want to use custom IO, preallocate the format context and set its pb field.

AVFormatSeekFile wraps avformat_seek_file.

Seek to timestamp ts.
Seeking will be done so that the point from which all active streams
can be presented successfully will be closest to ts and within min/max_ts.
Active streams are all streams that have AVStream.discard < AVDISCARD_ALL.

If flags contain AVSEEK_FLAG_BYTE, then all timestamps are in bytes and
are the file position (this may not be supported by all demuxers).
If flags contain AVSEEK_FLAG_FRAME, then all timestamps are in frames
in the stream with stream_index (this may not be supported by all demuxers).
Otherwise all timestamps are in units of the stream selected by stream_index
or if stream_index is -1, in AV_TIME_BASE units.
If flags contain AVSEEK_FLAG_ANY, then non-keyframes are treated as
keyframes (this may not be supported by all demuxers).
If flags contain AVSEEK_FLAG_BACKWARD, it is ignored.

AVFormatStreamGroupAddStream wraps avformat_stream_group_add_stream.

Add an already allocated stream to a stream group.

When demuxing, it may be called by the demuxer in read_header(). If the
flag AVFMTCTX_NOHEADER is set in s.ctx_flags, then it may also
be called in read_packet().

When muxing, may be called by the user before avformat_write_header() after
having allocated a new group with avformat_stream_group_create() and stream with
avformat_new_stream().

User is required to call avformat_free_context() to clean up the allocation
by avformat_stream_group_add_stream().

@param stg stream group belonging to a media file.
@param st  stream in the media file to add to the group.

@retval 0                 success
@retval AVERROR(EEXIST)   the stream was already in the group
@retval "another negative error code" legitimate errors

an output media file.

@param s        Media file handle, must be allocated with
                avformat_alloc_context().
                Its \ref AVFormatContext.oformat "oformat" field must be set
                to the desired output format;
                Its \ref AVFormatContext.pb "pb" field must be set to an
                already opened ::AVIOContext.
@param options  An ::AVDictionary filled with AVFormatContext and
                muxer-private options.
                On return this parameter will be destroyed and replaced with
                a dict containing options that were not found. May be NULL.

@retval AVSTREAM_INIT_IN_WRITE_HEADER On success, if the codec had not already been
                                      fully initialized in avformat_init_output().
@retval AVSTREAM_INIT_IN_INIT_OUTPUT  On success, if the codec had already been fully

func AVFrameApplyCropping ¶

func AVFrameApplyCropping(frame *AVFrame, flags int) (int, error)

AVFrameApplyCropping wraps av_frame_apply_cropping.

Crop the given video AVFrame according to its crop_left/crop_top/crop_right/
crop_bottom fields. If cropping is successful, the function will adjust the
data pointers and the width/height fields, and set the crop fields to 0.

In all cases, the cropping boundaries will be rounded to the inherent
alignment of the pixel format. In some cases, such as for opaque hwaccel
formats, the left/top cropping is ignored. The crop fields are set to 0 even
if the cropping was rounded or ignored.

@param frame the frame which should be cropped
@param flags Some combination of AV_FRAME_CROP_* flags, or 0.

@return >= 0 on success, a negative AVERROR on error. If the cropping fields
were invalid, AVERROR(ERANGE) is returned, and nothing is changed.

func AVFrameCopy ¶

func AVFrameCopy(dst *AVFrame, src *AVFrame) (int, error)

AVFrameCopy wraps av_frame_copy.

Copy the frame data from src to dst.

This function does not allocate anything, dst must be already initialized and
allocated with the same parameters as src.

This function only copies the frame data (i.e. the contents of the data /
extended data arrays), not any other properties.

@return >= 0 on success, a negative AVERROR on error.

func AVFrameCopyProps ¶

func AVFrameCopyProps(dst *AVFrame, src *AVFrame) (int, error)

AVFrameCopyProps wraps av_frame_copy_props.

Copy only "metadata" fields from src to dst.

Metadata for the purpose of this function are those fields that do not affect
the data layout in the buffers.  E.g. pts, sample rate (for audio) or sample
aspect ratio (for video), but not width/height or channel layout.
Side data is also copied.

func AVFrameFree ¶

func AVFrameFree(frame **AVFrame)

AVFrameFree wraps av_frame_free.

Free the frame and any dynamically allocated objects in it,
e.g. extended_data. If the frame is reference counted, it will be
unreferenced first.

@param frame frame to be freed. The pointer will be set to NULL.

func AVFrameGetBuffer ¶

func AVFrameGetBuffer(frame *AVFrame, align int) (int, error)

AVFrameGetBuffer wraps av_frame_get_buffer.

Allocate new buffer(s) for audio or video data.

The following fields must be set on frame before calling this function:
- format (pixel format for video, sample format for audio)
- width and height for video
- nb_samples and ch_layout for audio

This function will fill AVFrame.data and AVFrame.buf arrays and, if
necessary, allocate and fill AVFrame.extended_data and AVFrame.extended_buf.
For planar formats, one buffer will be allocated for each plane.

@warning: if frame already has been allocated, calling this function will
          leak memory. In addition, undefined behavior can occur in certain
          cases.

@param frame frame in which to store the new buffers.
@param align Required buffer size and data pointer alignment. If equal to 0,
             alignment will be chosen automatically for the current CPU.
             It is highly recommended to pass 0 here unless you know what

@return A positive value if the frame data is writable (which is true if and
only if each of the underlying buffers has only one reference, namely the one
stored in this frame). Return 0 otherwise.

If 1 is returned the answer is valid until av_buffer_ref() is called on any
of the underlying AVBufferRefs (e.g. through av_frame_ref() or directly).

@see av_frame_make_writable(), av_buffer_is_writable()

func AVFrameMakeWritable ¶

func AVFrameMakeWritable(frame *AVFrame) (int, error)

AVFrameMakeWritable wraps av_frame_make_writable.

Ensure that the frame data is writable, avoiding data copy if possible.

Do nothing if the frame is writable, allocate new buffers and copy the data
if it is not. Non-refcounted frames behave as non-writable, i.e. a copy
is always made.

@return 0 on success, a negative AVERROR on error.

@see av_frame_is_writable(), av_buffer_is_writable(),
av_buffer_make_writable()

func AVFrameMoveRef ¶

func AVFrameMoveRef(dst *AVFrame, src *AVFrame)

AVFrameMoveRef wraps av_frame_move_ref.

Move everything contained in src to dst and reset src.

@warning: dst is not unreferenced, but directly overwritten without reading

AVFrameRef wraps av_frame_ref.

Set up a new reference to the data described by the source frame.

Copy frame properties from src to dst and create a new reference for each
AVBufferRef from src.

If src is not reference counted, new buffers are allocated and the data is
copied.

@warning: dst MUST have been either unreferenced with av_frame_unref(dst),
          or newly allocated with av_frame_alloc() before calling this
          function, or undefined behavior will occur.

@return 0 on success, a negative AVERROR on error

func AVFrameRemoveSideData ¶

func AVFrameRemoveSideData(frame *AVFrame, _type AVFrameSideDataType)

AVFrameRemoveSideData wraps av_frame_remove_side_data.

Remove and free all side data instances of the given type.

func AVFrameReplace ¶

func AVFrameReplace(dst *AVFrame, src *AVFrame) (int, error)

AVFrameReplace wraps av_frame_replace.

Ensure the destination frame refers to the same data described by the source
frame, either by creating a new reference for each AVBufferRef from src if
they differ from those in dst, by allocating new buffers and copying data if
src is not reference counted, or by unrefencing it if src is empty.

Frame properties on dst will be replaced by those from src.

func AVFreep ¶

func AVFreep(ptr unsafe.Pointer)

AVFreep wraps av_freep.

Free a memory block which has been allocated with a function of av_malloc()
or av_realloc() family, and set the pointer pointing to it to `NULL`.

@code{.c}
uint8_t *buf = av_malloc(16);
av_free(buf);
buf now contains a dangling pointer to freed memory, and accidental
dereference of buf will result in a use-after-free, which may be a
security risk.

uint8_t *buf = av_malloc(16);
av_freep(&buf);
buf is now NULL, and accidental dereference will only result in a
NULL-pointer dereference.
@endcode

@param ptr Pointer to the pointer to the memory block which should be freed

representing the picture type, '?' if pict_type is unknown

func AVGetPixFmtLoss ¶

func AVGetPixFmtLoss(dstPixFmt AVPixelFormat, srcPixFmt AVPixelFormat, hasAlpha int) (int, error)

AVGetPixFmtLoss wraps av_get_pix_fmt_loss.

Compute what kind of losses will occur when converting from one specific
pixel format to another.
When converting from one pixel format to another, information loss may occur.

be lost. Similarly, other losses occur when converting from some formats to
other formats. These losses can involve loss of chroma, but also loss of
resolution, loss of color depth, loss due to the color space conversion, loss
of the alpha bits or loss due to color quantization.
av_get_fix_fmt_loss() informs you about the various types of losses
which will occur when converting from one pixel format to another.

Get the current time in microseconds.

func AVGettimeRelative ¶

func AVGettimeRelative() int64

AVGettimeRelative wraps av_gettime_relative.

AVHWDeviceCtxCreate wraps av_hwdevice_ctx_create.

Open a device of the specified type and create an AVHWDeviceContext for it.

This is a convenience function intended to cover the simple cases. Callers
who need to fine-tune device creation/management should open the device
manually and then wrap it in an AVHWDeviceContext using
av_hwdevice_ctx_alloc()/av_hwdevice_ctx_init().

The returned context is already initialized and ready for use, the caller
should not call av_hwdevice_ctx_init() on it. The user_opaque/free fields of
the created AVHWDeviceContext are set by this function and should not be
touched by the caller.

@param device_ctx On success, a reference to the newly-created device context
                  will be written here. The reference is owned by the caller
                  and must be released with av_buffer_unref() when no longer
                  needed. On failure, NULL will be written to this pointer.
@param type The type of the device to create.
@param device A type-specific string identifying the device to open.
@param opts A dictionary of additional (type-specific) options to use in
            opening the device. The dictionary remains owned by the caller.
@param flags currently unused

Create a new device of the specified type from an existing device.

If the source device is a device of the target type or was originally
derived from such a device (possibly through one or more intermediate
devices of other types), then this will return a reference to the
existing device of the same type as is requested.

Otherwise, it will attempt to derive a new device from the given source
device.  If direct derivation to the new type is not implemented, it will
attempt the same derivation from each ancestor of the source device in
turn looking for an implemented derivation method.

@param dst_ctx On success, a reference to the newly-created
               AVHWDeviceContext.
@param type    The type of the new device to create.

func AVHWFrameCtxCreateDerived(derivedFrameCtx **AVBufferRef, format AVPixelFormat, derivedDeviceCtx *AVBufferRef, sourceFrameCtx *AVBufferRef, flags int) (int, error)

AVHWFrameCtxCreateDerived wraps av_hwframe_ctx_create_derived.

Create and initialise an AVHWFramesContext as a mapping of another existing
AVHWFramesContext on a different device.

av_hwframe_ctx_init() should not be called after this.

@param derived_frame_ctx  On success, a reference to the newly created
                          AVHWFramesContext.
@param format             The AVPixelFormat for the derived context.
@param derived_device_ctx A reference to the device to create the new
                          AVHWFramesContext on.

             newly allocated buffers.
@param flags currently unused, should be set to zero
@return 0 on success, a negative AVERROR code on failure

func AVHWFrameMap ¶

func AVHWFrameMap(dst *AVFrame, src *AVFrame, flags int) (int, error)

AVHWFrameMap wraps av_hwframe_map.

Map a hardware frame.

This has a number of different possible effects, depending on the format
and origin of the src and dst frames.  On input, src should be a usable
frame with valid buffers and dst should be blank (typically as just created
by av_frame_alloc()).  src should have an associated hwframe context, and
dst may optionally have a format and associated hwframe context.

If src was created by mapping a frame from the hwframe context of dst,
then this function undoes the mapping - dst is replaced by a reference to
the frame that src was originally mapped from.

If both src and dst have an associated hwframe context, then this function
attempts to map the src frame from its hardware context to that of dst and
then fill dst with appropriate data to be usable there.  This will only be
possible if the hwframe contexts and associated devices are compatible -
given compatible devices, av_hwframe_ctx_create_derived() can be used to
create a hwframe context for dst in which mapping should be possible.

If src has a hwframe context but dst does not, then the src frame is
mapped to normal memory and should thereafter be usable as a normal frame.
If the format is set on dst, then the mapping will attempt to create dst
with that format and fail if it is not possible.  If format is unset (is
AV_PIX_FMT_NONE) then dst will be mapped with whatever the most appropriate
format to use is (probably the sw_format of the src hwframe context).

A return value of AVERROR(ENOSYS) indicates that the mapping is not
possible with the given arguments and hwframe setup, while other return
values indicate that it failed somehow.

On failure, the destination frame will be left blank, except for the
hw_frames_ctx/format fields they may have been set by the caller - those will
be preserved as they were.

@param dst Destination frame, to contain the mapping.
@param src Source frame, to be mapped.
@param flags Some combination of AV_HWFRAME_MAP_* flags.
@return Zero on success, negative AVERROR code on failure.

func AVHWFrameTransferData ¶

func AVHWFrameTransferData(dst *AVFrame, src *AVFrame, flags int) (int, error)

AVHWFrameTransferData wraps av_hwframe_transfer_data.

Copy data to or from a hw surface. At least one of dst/src must have an
AVHWFramesContext attached.

If src has an AVHWFramesContext attached, then the format of dst (if set)
must use one of the formats returned by av_hwframe_transfer_get_formats(src,
AV_HWFRAME_TRANSFER_DIRECTION_FROM).
If dst has an AVHWFramesContext attached, then the format of src must use one
of the formats returned by av_hwframe_transfer_get_formats(dst,
AV_HWFRAME_TRANSFER_DIRECTION_TO)

dst may be "clean" (i.e. with data/buf pointers unset), in which case the
data buffers will be allocated by this function using av_frame_get_buffer().
If dst->format is set, then this format will be used, otherwise (when
dst->format is AV_PIX_FMT_NONE) the first acceptable format will be chosen.

The two frames must have matching allocated dimensions (i.e. equal to
AVHWFramesContext.width/height), since not all device types support
transferring a sub-rectangle of the whole surface. The display dimensions
(i.e. AVFrame.width/height) may be smaller than the allocated dimensions, but
also have to be equal for both frames. When the display dimensions are
smaller than the allocated dimensions, the content of the padding in the
destination frame is unspecified.

@param dst the destination frame. dst is not touched on failure.
@param src the source frame.
@param flags currently unused, should be set to zero
@return 0 on success, a negative AVERROR error code on failure.

func AVHashAlloc ¶

AVIOCheck wraps avio_check.

Return AVIO_FLAG_* access flags corresponding to the access permissions
of the resource in url, or a negative value corresponding to an
AVERROR code in case of failure. The returned access flags are
masked by the value in flags.

more can be read from pb. The result is guaranteed to be NULL-terminated, it
will be truncated if buf is too small.
Note that the string is not interpreted or validated in any way, it
might get truncated in the middle of a sequence for multi-byte encodings.

using it as a read/write context.
It is separate from avio_accept() because it may block.
A step of the handshake is defined by places where the application may
decide to change the proceedings.
For example, on a protocol with a request header and a reply header, each
one can constitute a step because the application may use the parameters
from the request to change parameters in the reply; or each individual
chunk of the request can constitute a step.
If the handshake is already finished, avio_handshake() does nothing and
returns 0 immediately.

@param  c the client context to perform the handshake on

func AVInterleavedWriteFrame ¶

func AVInterleavedWriteFrame(s *AVFormatContext, pkt *AVPacket) (int, error)

AVInterleavedWriteFrame wraps av_interleaved_write_frame.

Write a packet to an output media file ensuring correct interleaving.

This function will buffer the packets internally as needed to make sure the
packets in the output file are properly interleaved, usually ordered by
increasing dts. Callers doing their own interleaving should call
av_write_frame() instead of this function.

Using this function instead of av_write_frame() can give muxers advance
knowledge of future packets, improving e.g. the behaviour of the mp4
muxer for VFR content in fragmenting mode.

@param s media file handle
@param pkt The packet containing the data to be written.
           <br>
           If the packet is reference-counted, this function will take
           ownership of this reference and unreference it later when it sees
           fit. If the packet is not reference-counted, libavformat will
           make a copy.
           The returned packet will be blank (as if returned from
           av_packet_alloc()), even on error.
           <br>
           This parameter can be NULL (at any time, not just at the end), to
           flush the interleaving queues.
           <br>
           Packet's @ref AVPacket.stream_index "stream_index" field must be
           set to the index of the corresponding stream in @ref
           AVFormatContext.streams "s->streams".
           <br>
           The timestamps (@ref AVPacket.pts "pts", @ref AVPacket.dts "dts")
           must be set to correct values in the stream's timebase (unless the
           output format is flagged with the AVFMT_NOTIMESTAMPS flag, then
           they can be set to AV_NOPTS_VALUE).
           The dts for subsequent packets in one stream must be strictly
           increasing (unless the output format is flagged with the
           AVFMT_TS_NONSTRICT, then they merely have to be nondecreasing).
           @ref AVPacket.duration "duration" should also be set if known.

@return 0 on success, a negative AVERROR on error.

@see av_write_frame(), AVFormatContext.max_interleave_delta

func AVInterleavedWriteUncodedFrame ¶

func AVInterleavedWriteUncodedFrame(s *AVFormatContext, streamIndex int, frame *AVFrame) (int, error)

AVInterleavedWriteUncodedFrame wraps av_interleaved_write_uncoded_frame.

Write an uncoded frame to an output media file.

If the muxer supports it, this function makes it possible to write an AVFrame
structure directly, without encoding it into a packet.
It is mostly useful for devices and similar special muxers that use raw
video or PCM data and will not serialize it into a byte stream.

To test whether it is possible to use it with a given muxer and stream,
use av_write_uncoded_frame_query().

The caller gives up ownership of the frame and must not access it
afterwards.

@return  >=0 for success, a negative code on error

Original memory allocated for such options is freed unless both src and dest options points to the same memory.

Even on error it is guaranteed that allocated options from src and dest
no longer alias each other afterwards; in particular calling av_opt_free()
on both src and dest is safe afterwards if dest has been memdup'ed from src.

                av_opt_get_array_size()

@param out_type Option type corresponding to the desired output.

                The array elements produced by this function will
                will be as if av_opt_getX() was called for each element,
                where X is specified by out_type. E.g. AV_OPT_TYPE_STRING
                corresponds to av_opt_get().

                Typically this should be the same as the scalarized type of
                the AVOption being retrieved, but certain conversions are
                also possible - the same as those done by the corresponding
                av_opt_get*() function. E.g. any option type can be retrieved
                as a string, numeric types can be retrieved as int64, double,
                or rational, etc.

@param out_val  Array with nb_elems members into which the output will be
                written. The array type must match the underlying C type as
                documented for out_type, and be zeroed on entry to this
                function.

                For dynamically allocated types (strings, binary, dicts,

Those functions set the field of obj with the given name to value.

@param[in] obj A struct whose first element is a pointer to an AVClass.
@param[in] name the name of the field to set
@param[in] val The value to set. In case of av_opt_set() if the field is not
of a string type, then the given string is parsed.
SI postfixes and some named scalars are supported.
If the field is of a numeric type, it has to be a numeric or named
scalar. Behavior with more than one scalar and +- infix operators
is undefined.
If the field is of a flags type, it has to be a sequence of numeric
scalars or named flags separated by '+' or '-'. Prefixing a flag
with '+' causes it to be set without affecting the other flags;
similarly, '-' unsets a flag.
If the field is of a dictionary type, it has to be a ':' separated list of
key=value parameters. Values containing ':' special characters must be
escaped.
@param search_flags flags passed to av_opt_find2. I.e. if AV_OPT_SEARCH_CHILDREN
is passed here, then the option may be set on a child of obj.

@return 0 if the value has been set, or an AVERROR code in case of
error:
AVERROR_OPTION_NOT_FOUND if no matching option exists
AVERROR(ERANGE) if the value is out of range
AVERROR(EINVAL) if the value is not valid

func AVOptSetArray ¶

operations is performed depends on the values of val and search_flags.

@param start_elem Index of the first array element to modify; must not be
                  larger than array size as returned by
                  av_opt_get_array_size().
@param nb_elems number of array elements to modify; when val is NULL,
                start_elem+nb_elems must not be larger than array size as
                returned by av_opt_get_array_size()

@param val_type Option type corresponding to the type of val, ignored when val is
                NULL.

                The effect of this function will will be as if av_opt_setX()
                was called for each element, where X is specified by type.
                E.g. AV_OPT_TYPE_STRING corresponds to av_opt_set().

                Typically this should be the same as the scalarized type of
                the AVOption being set, but certain conversions are also
                possible - the same as those done by the corresponding
                av_opt_set*() function. E.g. any option type can be set from
                a string, numeric types can be set from int64, double, or
                rational, etc.

@param val Array with nb_elems elements or NULL.

           When NULL, nb_elems array elements starting at start_elem are
           removed from the array. Any array elements remaining at the end
           are shifted by nb_elems towards the first element in order to keep
           the array contiguous.

           Otherwise (val is non-NULL), the type of val must match the
           underlying C type as documented for val_type.

           When AV_OPT_ARRAY_REPLACE is not set in search_flags, the array is
           enlarged by nb_elems, and the contents of val are inserted at
           start_elem. Previously existing array elements from start_elem
           onwards (if present) are shifted by nb_elems away from the first
           element in order to make space for the new elements.

           When AV_OPT_ARRAY_REPLACE is set in search_flags, the contents
           of val replace existing array elements from start_elem to
           start_elem+nb_elems (if present). New array size is
           max(start_elem + nb_elems, old array size).

               Of course this new dictionary needs to be freed by caller
               with av_dict_free().

This function returns what is stored in the file, and does not validate
that what is there are valid frames for the decoder. It will split what is
stored in the file into frames and return one for each call. It will not
omit invalid data between valid frames so as to give the decoder the maximum
information possible for decoding.

On success, the returned packet is reference-counted (pkt->buf is set) and
valid indefinitely. The packet must be freed with av_packet_unref() when
it is no longer needed. For video, the packet contains exactly one frame.
For audio, it contains an integer number of frames if each frame has
a known fixed size (e.g. PCM or ADPCM data). If the audio frames have
a variable size (e.g. MPEG audio), then it contains one frame.

pkt->pts, pkt->dts and pkt->duration are always set to correct
values in AVStream.time_base units (and guessed if the format cannot
provide them). pkt->pts can be AV_NOPTS_VALUE if the video format
has B-frames, so it is better to rely on pkt->dts if you do not
decompress the payload.

@return 0 if OK, < 0 on error or end of file. On error, pkt will be blank

           output format is flagged with the AVFMT_NOTIMESTAMPS flag, then
           they can be set to AV_NOPTS_VALUE).
           The dts for subsequent packets passed to this function must be strictly
           increasing when compared in their respective timebases (unless the
           output format is flagged with the AVFMT_TS_NONSTRICT, then they
           merely have to be nondecreasing).  @ref AVPacket.duration
           "duration") should also be set if known.
@return < 0 on error, = 0 if OK, 1 if flushed and there is no more data to flush

SwrAllocSetOpts2 wraps swr_alloc_set_opts2.

Allocate SwrContext if needed and set/reset common parameters.

This function does not require *ps to be allocated with swr_alloc(). On the
other hand, swr_alloc() can use swr_alloc_set_opts2() to set the parameters
on the allocated context.

@param ps              Pointer to an existing Swr context if available, or to NULL if not.
                       On success, *ps will be set to the allocated context.

func SwrClose ¶

func SwrClose(s *SwrContext)

SwrClose wraps swr_close.

Closes the context so that swr_is_initialized() returns 0.

The context can be brought back to life by running swr_init(),
swr_init() can also be used without swr_close().
This function is mainly provided for simplifying the usecase
where one tries to support libavresample and libswresample.

@param[in,out] s Swr context to be closed

func SwrConfigFrame ¶

func SwrConfigFrame(swr *SwrContext, out *AVFrame, in *AVFrame) (int, error)

SwrConfigFrame wraps swr_config_frame.

Configure or reconfigure the SwrContext using the information
provided by the AVFrames.

The original resampling context is reset even on failure.
The function calls swr_close() internally if the context is open.

@see swr_close();

@param swr             audio resample context
@param out             output AVFrame
@param in              input AVFrame

func SwrConvertFrame ¶

func SwrConvertFrame(swr *SwrContext, output *AVFrame, input *AVFrame) (int, error)

SwrConvertFrame wraps swr_convert_frame.

Convert the samples in the input AVFrame and write them to the output AVFrame.

Input and output AVFrames must have channel_layout, sample_rate and format set.

If the output AVFrame does not have the data pointers allocated the nb_samples
field will be set using av_frame_get_buffer()
is called to allocate the frame.

The output AVFrame can be NULL or have fewer allocated samples than required.
In this case, any remaining samples not written to the output will be added
to an internal FIFO buffer, to be returned at the next call to this function
or to swr_convert().

If converting sample rate, there may be data remaining in the internal
resampling delay buffer. swr_get_delay() tells the number of
remaining samples. To get this data as output, call this function or
swr_convert() with NULL input.

If the SwrContext configuration does not match the output and
input AVFrame settings the conversion does not take place and depending on
which AVFrame is not matching AVERROR_OUTPUT_CHANGED, AVERROR_INPUT_CHANGED
or the result of a bitwise-OR of them is returned.

@see swr_delay()
@see swr_convert()
@see swr_get_delay()

@param swr             audio resample context
@param output          output AVFrame
@param input           input AVFrame
@return                0 on success, AVERROR on failure or nonmatching
                       configuration.

func SwrDropOutput ¶

func SwrDropOutput(s *SwrContext, count int) (int, error)

SwrDropOutput wraps swr_drop_output.

@return >= 0 on success, or a negative AVERROR code on failure

func SwrFree ¶

func SwrFree(s **SwrContext)

SwrFree wraps swr_free.

Free the given SwrContext and set the pointer to NULL.

@param[in] s a pointer to a pointer to Swr context

func SwrGetDelay ¶

func SwrGetDelay(s *SwrContext, base int64) int64

SwrGetDelay wraps swr_get_delay.

Gets the delay the next input sample will experience relative to the next output sample.

Swresample can buffer data if more input has been provided than available
output space, also converting between sample rates needs a delay.
This function returns the sum of all such delays.
The exact delay is not necessarily an integer value in either input or
output sample rate. Especially when downsampling by a large value, the
output sample rate may be a poor choice to represent the delay, similarly
for upsampling and the input sample rate.

@param s     swr context
@param base  timebase in which the returned delay will be:
             @li if it's set to 1 the returned delay is in seconds
             @li if it's set to 1000 the returned delay is in milliseconds
             @li if it's set to the input sample rate then the returned
                 delay is in input samples
             @li if it's set to the output sample rate then the returned
                 delay is in output samples
             @li if it's the least common multiple of in_sample_rate and
                 out_sample_rate then an exact rounding-free delay will be
                 returned
@returns     the delay in 1 / @c base units.

func SwrGetOutSamples ¶

func SwrGetOutSamples(s *SwrContext, inSamples int) (int, error)

SwrGetOutSamples wraps swr_get_out_samples.

Find an upper bound on the number of samples that the next swr_convert
call will output, if called with in_samples of input samples. This
depends on the internal state, and anything changing the internal state
(like further swr_convert() calls) will may change the number of samples
swr_get_out_samples() returns for the same number of input samples.

@param in_samples    number of input samples.
@note any call to swr_inject_silence(), swr_convert(), swr_next_pts()
      or swr_set_compensation() invalidates this limit
@note it is recommended to pass the correct available buffer size
      to all functions like swr_convert() even if swr_get_out_samples()
      indicates that less would be used.
@returns an upper bound on the number of samples that the next swr_convert
         will output or a negative value to indicate an error

func SwrInit ¶

@return AVERROR error code in case of failure.

func SwrInjectSilence ¶

@param[in]       s Swr context to check
@see swr_init()
@return positive if it has been initialized, 0 if not initialized

func SwrNextPts ¶

func SwrNextPts(s *SwrContext, pts int64) int64

SwrNextPts wraps swr_next_pts.

Convert the next timestamp from input to output
timestamps are in 1/(in_sample_rate * out_sample_rate) units.

@note There are 2 slightly differently behaving modes.
      @li When automatic timestamp compensation is not used, (min_compensation >= FLT_MAX)
             in this case timestamps will be passed through with delays compensated
      @li When automatic timestamp compensation is used, (min_compensation < FLT_MAX)
             in this case the output timestamps will match output sample numbers.
             See ffmpeg-resampler(1) for the two modes of compensation.

@param[in] s     initialized Swr context
@param[in] pts   timestamp for the next input sample, INT64_MIN if unknown
@see swr_set_compensation(), swr_drop_output(), and swr_inject_silence() are
     function used internally for timestamp compensation.
@return the output timestamp for the next output sample

func SwrSetChannelMapping ¶

func SwrSetChannelMapping(s *SwrContext, channelMap *int) (int, error)

@param[in]     channel_map customized input channel mapping (array of channel
                           indexes, -1 for a muted channel)
@return >= 0 on success, or AVERROR error code in case of failure.

func SwrSetCompensation ¶

func SwrSetCompensation(s *SwrContext, sampleDelta int, compensationDistance int) (int, error)

SwrSetCompensation wraps swr_set_compensation.

Activate resampling compensation ("soft" compensation). This function is
internally called when needed in swr_next_pts().

@param[in,out] s             allocated Swr context. If it is not initialized,
                             or SWR_FLAG_RESAMPLE is not set, swr_init() is
                             called with the flag set.
@param[in]     sample_delta  delta in PTS per sample
@param[in]     compensation_distance number of samples to compensate for

@returns     the unsigned int-typed version

func SwsConvertpalette8Topacked24 ¶

func SwsConvertpalette8Topacked24(src unsafe.Pointer, dst unsafe.Pointer, numPixels int, palette unsafe.Pointer)

SwsConvertpalette8Topacked24 wraps sws_convertPalette8ToPacked24.

@param c   The scaling context

func SwsFrameSetup ¶

func SwsFrameSetup(ctx *SwsContext, dst *AVFrame, src *AVFrame) (int, error)

SwsFrameSetup wraps sws_frame_setup.

merely initialize internal state that *would* be required to perform the
operation, as well as returning the correct error code for unsupported
frame combinations.

@param ctx   The scaling context.
@param dst   The destination frame to consider.
@param src   The source frame to consider.
@return 0 on success, a negative AVERROR code on failure.

Must be called before any calls to sws_send_slice() and sws_receive_slice().
Requires a context that has been previously been initialized with

This function will retain references to src and dst, so they must both use
refcounted buffers (if allocated by the caller, in case of dst).

@param c   The scaling context
@param dst The destination frame.

           The data buffers may either be already allocated by the caller or
           left clear, in which case they will be allocated by the scaler.
           The latter may have performance advantages - e.g. in certain cases
           some output planes may be references to input planes, rather than
           copies.

           Output data will be written into this frame in successful
           sws_receive_slice() calls.
@param src The source frame. The data buffers must be allocated, but the
           frame data does not have to be ready at this point. Data
           availability is then signalled by sws_send_slice().
@return 0 on success, a negative AVERROR code on failure

@see sws_frame_end()

SwsInitContext wraps sws_init_context.

Initialize the swscaler context sws_context.

This function is considered deprecated, and provided only for backwards
compatibility with sws_scale() and sws_start_frame(). The preferred way to
use libswscale is to set all frame properties correctly and call
sws_scale_frame() directly, without explicitly initializing the context.

                    frame height)

@return a non-negative number if the data was successfully written into the output
        AVERROR(EAGAIN) if more input data needs to be provided before the

        multiples of the value returned from this function.

func SwsScaleFrame ¶

func SwsScaleFrame(c *SwsContext, dst *AVFrame, src *AVFrame) (int, error)

SwsScaleFrame wraps sws_scale_frame.

Scale source data from `src` and write the output to `dst`.

This function can be used directly on an allocated context, without setting
up any frame properties or calling `sws_init_context()`. Such usage is fully
dynamic and does not require reallocation if the frame properties change.

Alternatively, this function can be called on a context that has been
explicitly initialized. However, this is provided only for backwards
compatibility. In this usage mode, all frame properties must be correctly
set at init time, and may no longer change after initialization.

@param ctx   The scaling context.
@param dst   The destination frame. The data buffers may either be already
             allocated by the caller or left clear, in which case they will
             be allocated by the scaler. The latter may have performance
             advantages - e.g. in certain cases some (or all) output planes
             may be references to input planes, rather than copies.
@param src   The source frame. If the data buffers are set to NULL, then
             this function behaves identically to `sws_frame_setup`.
@return >= 0 on success, a negative AVERROR code on failure.

Indicate that a horizontal slice of input data is available in the source
frame previously provided to sws_frame_start(). The slices may be provided in
any order, but may not overlap. For vertically subsampled pixel formats, the
slices must be aligned according to subsampling.

@param c   The scaling context
@param slice_start first row of the slice
@param slice_height number of rows in the slice

@return a non-negative number on success, a negative AVERROR code on failure.

func SwsTestTransfer ¶

func SwsTestTransfer(trc AVColorTransferCharacteristic, output int) (int, error)

type AVBPrint ¶

type AVBPrint struct {
	// contains filtered or unexported fields
}

AVBPrint wraps AVBPrint.

Buffer to print data progressively

The string buffer grows as necessary and is always 0-terminated.
The content of the string is never accessed, and thus is
encoding-agnostic and can even hold binary data.

Small buffers are kept in the structure itself, and thus require no
memory allocation at all (unless the contents of the buffer is needed
after the structure goes out of scope). This is almost as lightweight as
declaring a local `char buf[512]`.

The length of the string can go beyond the allocated size: the buffer is
then truncated, but the functions still keep account of the actual total
length.

In other words, AVBPrint.len can be greater than AVBPrint.size and records
the total length of what would have been to the buffer if there had been
enough memory.

Append operations do not need to be tested for failure: if a memory
allocation fails, data stop being appended to the buffer, but the length
is still updated. This situation can be tested with
av_bprint_is_complete().

The AVBPrint.size_max field determines several possible behaviours:
- `size_max = -1` (= `UINT_MAX`) or any large value will let the buffer be
  reallocated as necessary, with an amortized linear cost.
- `size_max = 0` prevents writing anything to the buffer: only the total
  length is computed. The write operations can then possibly be repeated in
  a buffer with exactly the necessary size
  (using `size_init = size_max = len + 1`).
- `size_max = 1` is automatically replaced by the exact size available in the
  structure itself, thus ensuring no dynamic memory allocation. The
  internal buffer is large enough to hold a reasonable paragraph of text,
  such as the current paragraph.

type AVChannelLayout ¶

type AVChannelLayout struct {

}

AVChannelLayout wraps AVChannelLayout.

An AVChannelLayout holds information about the channel layout of audio data.

A channel layout here is defined as a set of channels ordered in a specific
way (unless the channel order is AV_CHANNEL_ORDER_UNSPEC, in which case an
AVChannelLayout carries only the channel count).
All orders may be treated as if they were AV_CHANNEL_ORDER_UNSPEC by
ignoring everything but the channel count, as long as av_channel_layout_check()
considers they are valid.

Unlike most structures in FFmpeg, sizeof(AVChannelLayout) is a part of the
public ABI and may be used by the caller. E.g. it may be allocated on stack
or embedded in caller-defined structs.

AVChannelLayout can be initialized as follows:
- default initialization with {0}, followed by setting all used fields
  correctly;
- by assigning one of the predefined AV_CHANNEL_LAYOUT_* initializers;
- with a constructor function, such as av_channel_layout_default(),
  av_channel_layout_from_mask() or av_channel_layout_from_string().

The channel layout must be uninitialized with av_channel_layout_uninit()

Copying an AVChannelLayout via assigning is forbidden,
av_channel_layout_copy() must be used instead (and its return value should
be checked)

No new fields may be added to it without a major version bump, except for
new elements of the union fitting in sizeof(uint64_t).

The name string for AVOptions options matches the associated command line
parameter name and can be found in libavcodec/options_table.h
The AVOption/command line parameter names differ in some cases from the C
structure field names for historic reasons or brevity.
sizeof(AVCodecContext) must not be used outside libav*.

func AVCodecAllocContext3 ¶

func AVCodecAllocContext3(codec *AVCodec) *AVCodecContext

AVCodecAllocContext3 wraps avcodec_alloc_context3.

Allocate an AVCodecContext and set its fields to default values. The

func (*AVCodecContext) ApplyCropping ¶

func (s *AVCodecContext) ApplyCropping() int

ApplyCropping gets the apply_cropping field.

Video decoding only. Certain video codecs support cropping, meaning that
only a sub-rectangle of the decoded frame is intended for display.  This
option controls how cropping is handled by libavcodec.

When set to 1 (the default), libavcodec will apply cropping internally.
I.e. it will modify the output frame width/height fields and offset the
data pointers (only by as much as possible while preserving alignment, or
by the full amount if the AV_CODEC_FLAG_UNALIGNED flag is set) so that
the frames output by the decoder refer only to the cropped area. The
crop_* fields of the output frames will be zero.

When set to 0, the width/height fields of the output frames will be set
to the coded dimensions and the crop_* fields will describe the cropping
rectangle. Applying the cropping is left to the caller.

@warning When hardware acceleration with opaque output frames is used,
libavcodec is unable to apply cropping from the top/left border.

@note when this option is set to zero, the width/height fields of the
AVCodecContext and output AVFrames have different meanings. The codec
context fields store display dimensions (with the coded dimensions in
coded_width/height), while the frame fields store the coded dimensions
(with the display dimensions being determined by the crop_* fields).

If there are multiple such fields in a container then the demuxer should choose the one
which maximizes the information about the used codec.
If the codec tag field in a container is larger than 32 bits then the demuxer should
remap the longer ID to 32 bits with a table or other structure. Alternatively a new
extra_codec_tag + size could be added but for this a clear advantage must be demonstrated

reordering.

- encoding: MUST be set by user.
- decoding: May be set by the user before opening the decoder if known e.g.
            from the container. Some decoders will require the dimensions
            to be set by the caller. During decoding, the decoder may
            overwrite those values as required while parsing the data.

func (*AVCodecContext) HwDeviceCtx ¶

func (s *AVCodecContext) HwDeviceCtx() *AVBufferRef

HwDeviceCtx gets the hw_device_ctx field.

A reference to the AVHWDeviceContext describing the device which will
be used by a hardware encoder/decoder.  The reference is set by the
caller and afterwards owned (and freed) by libavcodec.

This should be used if either the codec device does not require
hardware frames or any that are used are to be allocated internally by
libavcodec.  If the user wishes to supply any of the frames used as
encoder input or decoder output then hw_frames_ctx should be used
instead.  When hw_frames_ctx is set in get_format() for a decoder, this
field will be ignored while decoding the associated stream segment, but
may again be used on a following one after another get_format() call.

For both encoders and decoders this field should be set before
avcodec_open2() is called and must not be written to thereafter.

Note that some decoders may require this field to be set initially in
order to support hw_frames_ctx at all - in that case, all frames
contexts used must be created on the same device.

func (*AVCodecContext) HwFramesCtx ¶

func (s *AVCodecContext) HwFramesCtx() *AVBufferRef

HwFramesCtx gets the hw_frames_ctx field.

A reference to the AVHWFramesContext describing the input (for encoding)
or output (decoding) frames. The reference is set by the caller and
afterwards owned (and freed) by libavcodec - it should never be read by
the caller after being set.

- decoding: This field should be set by the caller from the get_format()
            callback. The previous reference (if any) will always be
            unreffed by libavcodec before the get_format() call.

            If the default get_buffer2() is used with a hwaccel pixel
            format, then this AVHWFramesContext will be used for
            allocating the frame buffers.

- encoding: For hardware encoders configured to use a hwaccel pixel
            format, this field should be set by the caller to a reference
            to the AVHWFramesContext describing input frames.
            AVHWFramesContext.format must be equal to
            AVCodecContext.pix_fmt.

signal hwaccel-specific data to the codec. The struct pointed to by this
pointer is hwaccel-dependent and defined in the respective header. Please
refer to the FFmpeg HW accelerator documentation to know how to fill
this.

In most cases this field is optional - the necessary information may also
be provided to libavcodec through @ref hw_frames_ctx or @ref
hw_device_ctx (see avcodec_get_hw_config()). However, in some cases it
may be the only method of signalling some (optional) information.

The struct and its contents are owned by the caller.

- encoding: May be set by the caller before avcodec_open2(). Must remain
            valid until avcodec_free_context().
- decoding: May be set by the caller in the get_format() callback.
            Must remain valid until the next get_format() call,
            or avcodec_free_context() (whichever comes first).

- encoding: Set by libavcodec. The timestamps on the output packets are
            adjusted by the encoder so that they always refer to the
            first sample of the data actually contained in the packet,
            including any added padding.  E.g. if the timebase is
            1/samplerate and the timestamp of the first input sample is
            0, the timestamp of the first output packet will be
            -initial_padding.

func (s *AVCodecContext) SetApplyCropping(value int)

SetApplyCropping sets the apply_cropping field.

Video decoding only. Certain video codecs support cropping, meaning that
only a sub-rectangle of the decoded frame is intended for display.  This
option controls how cropping is handled by libavcodec.

When set to 1 (the default), libavcodec will apply cropping internally.
I.e. it will modify the output frame width/height fields and offset the
data pointers (only by as much as possible while preserving alignment, or
by the full amount if the AV_CODEC_FLAG_UNALIGNED flag is set) so that
the frames output by the decoder refer only to the cropped area. The
crop_* fields of the output frames will be zero.

When set to 0, the width/height fields of the output frames will be set
to the coded dimensions and the crop_* fields will describe the cropping
rectangle. Applying the cropping is left to the caller.

@warning When hardware acceleration with opaque output frames is used,
libavcodec is unable to apply cropping from the top/left border.

@note when this option is set to zero, the width/height fields of the

context fields store display dimensions (with the coded dimensions in
coded_width/height), while the frame fields store the coded dimensions
(with the display dimensions being determined by the crop_* fields).

This is used to work around some encoder bugs.
A demuxer should set this to what is stored in the field used to identify the codec.
If there are multiple such fields in a container then the demuxer should choose the one
which maximizes the information about the used codec.
If the codec tag field in a container is larger than 32 bits then the demuxer should
remap the longer ID to 32 bits with a table or other structure. Alternatively a new
extra_codec_tag + size could be added but for this a clear advantage must be demonstrated

            overwrite those values as required while parsing the data.

func (*AVCodecContext) SetHwDeviceCtx ¶

func (s *AVCodecContext) SetHwDeviceCtx(value *AVBufferRef)

SetHwDeviceCtx sets the hw_device_ctx field.

A reference to the AVHWDeviceContext describing the device which will
be used by a hardware encoder/decoder.  The reference is set by the
caller and afterwards owned (and freed) by libavcodec.

This should be used if either the codec device does not require
hardware frames or any that are used are to be allocated internally by
libavcodec.  If the user wishes to supply any of the frames used as
encoder input or decoder output then hw_frames_ctx should be used
instead.  When hw_frames_ctx is set in get_format() for a decoder, this
field will be ignored while decoding the associated stream segment, but
may again be used on a following one after another get_format() call.

For both encoders and decoders this field should be set before
avcodec_open2() is called and must not be written to thereafter.

            callback. The previous reference (if any) will always be
            unreffed by libavcodec before the get_format() call.

            If the default get_buffer2() is used with a hwaccel pixel
            format, then this AVHWFramesContext will be used for
            allocating the frame buffers.

- encoding: For hardware encoders configured to use a hwaccel pixel
            format, this field should be set by the caller to a reference
            to the AVHWFramesContext describing input frames.
            AVHWFramesContext.format must be equal to
            AVCodecContext.pix_fmt.

signal hwaccel-specific data to the codec. The struct pointed to by this
pointer is hwaccel-dependent and defined in the respective header. Please
refer to the FFmpeg HW accelerator documentation to know how to fill
this.

In most cases this field is optional - the necessary information may also
be provided to libavcodec through @ref hw_frames_ctx or @ref
hw_device_ctx (see avcodec_get_hw_config()). However, in some cases it
may be the only method of signalling some (optional) information.

The struct and its contents are owned by the caller.

- encoding: May be set by the caller before avcodec_open2(). Must remain
            valid until avcodec_free_context().
- decoding: May be set by the caller in the get_format() callback.

            1/samplerate and the timestamp of the first input sample is
            0, the timestamp of the first output packet will be
            -initial_padding.

type AVFormatControlMessage ¶

type AVFormatControlMessage unsafe.Pointer

AVFormatControlMessage is a function pointer typedef for av_format_control_message.

type AVFrame ¶

type AVFrame struct {
	// contains filtered or unexported fields
}

AVFrame wraps AVFrame.

This structure describes decoded (raw) audio or video data.

AVFrame must be allocated using av_frame_alloc(). Note that this only
allocates the AVFrame itself, the buffers for the data must be managed
through other means (see below).
AVFrame must be freed with av_frame_free().

AVFrame is typically allocated once and then reused multiple times to hold
different data (e.g. a single AVFrame to hold frames received from a
decoder). In such a case, av_frame_unref() will free any references held by
the frame and reset it to its original clean state before it
is reused again.

The data described by an AVFrame is usually reference counted through the
AVBuffer API. The underlying buffer references are stored in AVFrame.buf /
AVFrame.extended_buf. An AVFrame is considered to be reference counted if at
least one reference is set, i.e. if AVFrame.buf[0] != NULL. In such a case,
every single data plane must be contained in one of the buffers in
AVFrame.buf or AVFrame.extended_buf.
There may be a single buffer for all the data, or one separate buffer for
each plane, or anything in between.

sizeof(AVFrame) is not a part of the public ABI, so new fields may be added
to the end with a minor bump.

Fields can be accessed through AVOptions, the name string used, matches the
C structure field name for fields accessible through AVOptions.

func AVFrameAlloc ¶

Allocate an AVFrame and set its fields to default values.  The resulting
struct must be freed using av_frame_free().

@note this only allocates the AVFrame itself, not the data buffers. Those
must be allocated through other means, e.g. with av_frame_get_buffer() or
manually.

func AVFrameClone ¶

func AVFrameClone(src *AVFrame) *AVFrame

AVFrameClone wraps av_frame_clone.

Create a new frame that references the same data as src.

This is a shortcut for av_frame_alloc()+av_frame_ref().

extended_buf. This array must be filled contiguously -- if buf[i] is
non-NULL then buf[j] must also be non-NULL for all j < i.

There may be at most one AVBuffer per data plane, so for video this array
always contains all the references. For planar audio with more than
AV_NUM_DATA_POINTERS channels, there may be more buffers than can fit in
this array. Then the extra AVBufferRef pointers are stored in the
extended_buf array.

type AVPacket ¶

type AVPacket struct {
	// contains filtered or unexported fields
}

AVPacket wraps AVPacket.

This structure stores compressed data. It is typically exported by demuxers
and then passed as input to decoders, or received as output from encoders and
then passed to muxers.

For video, it should typically contain one compressed frame. For audio it may
contain several compressed frames. Encoders are allowed to output empty
packets, with no compressed data, containing only side data
(e.g. to update some stream parameters at the end of encoding).

The semantics of data ownership depends on the buf field.
If it is set, the packet data is dynamically allocated and is
valid indefinitely until a call to av_packet_unref() reduces the
reference count to 0.

If the buf field is not set av_packet_ref() would make a copy instead
of increasing the reference count.

The side data is always allocated with av_malloc(), copied by
av_packet_ref() and freed by av_packet_unref().

sizeof(AVPacket) being a part of the public ABI is deprecated. once
av_init_packet() is removed, new packets will only be able to be allocated
with av_packet_alloc(), and new fields may be added to the end of the struct
with a minor bump.

@see av_packet_alloc
@see av_packet_ref
@see av_packet_unref

Allocate an AVPacket and set its fields to default values.  The resulting
struct must be freed using av_packet_free().

@return An AVPacket filled with default values or NULL on failure.

@note this only allocates the AVPacket itself, not the data buffers. Those
must be allocated through other means such as av_new_packet.

@see av_new_packet

func AVPacketClone ¶

func AVPacketClone(src *AVPacket) *AVPacket

AVPacketClone wraps av_packet_clone.

Create a new packet that references the same data as src.

This is a shortcut for av_packet_alloc()+av_packet_ref().

@see av_packet_alloc
@see av_packet_ref

type AVPacketSideData struct {
	// contains filtered or unexported fields
}

This structure stores auxiliary information for decoding, presenting, or
otherwise processing the coded stream. It is typically exported by demuxers
and encoders and can be fed to decoders and muxers either in a per packet
basis, or as global side data (applying to the entire coded stream).

Global side data is handled as follows:
- During demuxing, it may be exported through
  @ref AVCodecParameters.coded_side_data "AVStream's codec parameters", which can
  then be passed as input to decoders through the
  @ref AVCodecContext.coded_side_data "decoder context's side data", for
  initialization.
- For muxing, it can be fed through @ref AVCodecParameters.coded_side_data
  "AVStream's codec parameters", typically  the output of encoders through
  the @ref AVCodecContext.coded_side_data "encoder context's side data", for
  initialization.

Packet specific side data is handled as follows:
- During demuxing, it may be exported through @ref AVPacket.side_data
  "AVPacket's side data", which can then be passed as input to decoders.
- For muxing, it can be fed through @ref AVPacket.side_data "AVPacket's
  side data", typically the output of encoders.

Different modules may accept or export different types of side data
depending on media type and codec. Refer to @ref AVPacketSideDataType for a
list of defined types and where they may be found or used.

Pixel format.

@note
AV_PIX_FMT_RGB32 is handled in an endian-specific manner. An RGBA
color is put together as:
 (A << 24) | (R << 16) | (G << 8) | B
This is stored as BGRA on little-endian CPU architectures and ARGB on
big-endian CPUs.

@note
If the resolution is not a multiple of the chroma subsampling factor
then the chroma plane resolution must be rounded up.

@par
When the pixel format is palettized RGB32 (AV_PIX_FMT_PAL8), the palettized
image data is stored in AVFrame.data[0]. The palette is transported in
AVFrame.data[1], is 1024 bytes long (256 4-byte entries) and is
formatted the same as in AV_PIX_FMT_RGB32 described above (i.e., it is
also endian-specific). Note also that the individual RGB32 palette
components stored in AVFrame.data[1] should be in the range 0..255.
This is important as many custom PAL8 video codecs that were designed
to run on the IBM VGA graphics adapter use 6-bit palette components.

@par
For all the 8 bits per pixel formats, an RGB32 palette is in data[1] like
for pal8. This palette is filled in automatically by the function
allocating the picture.

other formats. These losses can involve loss of chroma, but also loss of
resolution, loss of color depth, loss due to the color space conversion, loss
of the alpha bits or loss due to color quantization.

can be recovered exactly from their double representation.
(no exceptions were found within 1B random ones)

Guess the sample aspect ratio of a frame, based on both the stream and the
frame aspect ratio.

Since the frame aspect ratio is set by the codec but the stream aspect ratio
is set by the demuxer, these two may not be equal. This function tries to
return the value that you should use if you would like to display the frame.

Basic logic is to use the stream aspect ratio if it is set to something sane
otherwise use the frame aspect ratio. This way a container setting, which is
usually easy to modify can override the coded value in the frames.

@param format the format context which the stream is part of
@param stream the stream which the frame is part of

type AVRegionOfInterest ¶

type AVRegionOfInterest struct {
	// contains filtered or unexported fields
}

AVRegionOfInterest wraps AVRegionOfInterest.

Structure describing a single Region Of Interest.

When multiple regions are defined in a single side-data block, they
should be ordered from most to least important - some encoders are only
capable of supporting a limited number of distinct regions, so will have
to truncate the list.

When overlapping regions are defined, the first region containing a given
area of the frame applies.

func (*AVRegionOfInterest) Bottom ¶

Bottom gets the bottom field.

func (*AVRegionOfInterest) Left ¶

func (s *AVRegionOfInterest) Left() int

func (*AVRegionOfInterest) Qoffset ¶

func (s *AVRegionOfInterest) Qoffset() *AVRational

Qoffset gets the qoffset field.

Quantisation offset.

Must be in the range -1 to +1.  A value of zero indicates no quality
change.  A negative value asks for better quality (less quantisation),
while a positive value asks for worse quality (greater quantisation).

The range is calibrated so that the extreme values indicate the
largest possible offset - if the rest of the frame is encoded with the
worst possible quality, an offset of -1 indicates that this region
should be encoded with the best possible quality anyway.  Intermediate
values are then interpolated in some codec-dependent way.

For example, in 10-bit H.264 the quantisation parameter varies between
-12 and 51.  A typical qoffset value of -1/10 therefore indicates that
this region should be encoded with a QP around one-tenth of the full
range better than the rest of the frame.  So, if most of the frame
were to be encoded with a QP of around 30, this region would get a QP
of around 24 (an offset of approximately -1/10 * (51 - -12) = -6.3).
An extreme value of -1 would indicate that this region should be
encoded with the best possible quality regardless of the treatment of
the rest of the frame - that is, should be encoded at a QP of -12.

func (*AVRegionOfInterest) SetQoffset ¶

SetQoffset sets the qoffset field.

Quantisation offset.

Must be in the range -1 to +1.  A value of zero indicates no quality
change.  A negative value asks for better quality (less quantisation),
while a positive value asks for worse quality (greater quantisation).

The range is calibrated so that the extreme values indicate the
largest possible offset - if the rest of the frame is encoded with the
worst possible quality, an offset of -1 indicates that this region
should be encoded with the best possible quality anyway.  Intermediate
values are then interpolated in some codec-dependent way.

For example, in 10-bit H.264 the quantisation parameter varies between
-12 and 51.  A typical qoffset value of -1/10 therefore indicates that
this region should be encoded with a QP around one-tenth of the full
range better than the rest of the frame.  So, if most of the frame
were to be encoded with a QP of around 30, this region would get a QP
of around 24 (an offset of approximately -1/10 * (51 - -12) = -6.3).
An extreme value of -1 would indicate that this region should be
encoded with the best possible quality regardless of the treatment of
the rest of the frame - that is, should be encoded at a QP of -12.

Distance in pixels from the top edge of the frame to the top and
bottom edges and from the left edge of the frame to the left and
right edges of the rectangle defining this region of interest.

The constraints on a region are encoder dependent, so the region
actually affected may be slightly larger for alignment or other
reasons.

func (*AVRegionOfInterest) Top ¶

func (s *AVRegionOfInterest) Top() int

Top gets the top field.

Distance in pixels from the top edge of the frame to the top and
bottom edges and from the left edge of the frame to the left and

type AVSampleFormat ¶

type AVSampleFormat C.enum_AVSampleFormat

AVSampleFormat wraps AVSampleFormat.

Audio sample formats

- The data described by the sample format is always in native-endian order.
  Sample values can be expressed by native C types, hence the lack of a signed
  24-bit sample format even though it is a common raw audio data format.

- The floating-point formats are based on full volume being in the range
  [-1.0, 1.0]. Any values outside this range are beyond full volume level.

- The data layout as used in av_samples_fill_arrays() and elsewhere in FFmpeg
  (such as AVFrame in libavcodec) is as follows:

@par
For planar sample formats, each audio channel is in a separate data plane,
and linesize is the buffer size, in bytes, for a single plane. All data
planes must be the same size. For packed sample formats, only the first data
plane is used, and samples for each channel are interleaved. In this case,
linesize is the buffer size, in bytes, for the 1 plane.

type AVStreamGroupTileGrid struct {
	// contains filtered or unexported fields
}

AVStreamGroupTileGrid wraps AVStreamGroupTileGrid.

AVStreamGroupTileGrid holds information on how to combine several
independent images on a single canvas for presentation.

The output should be a @ref AVStreamGroupTileGrid.background "background"
colored @ref AVStreamGroupTileGrid.coded_width "coded_width" x
@ref AVStreamGroupTileGrid.coded_height "coded_height" canvas where a
@ref AVStreamGroupTileGrid.nb_tiles "nb_tiles" amount of tiles are placed in
the order they appear in the @ref AVStreamGroupTileGrid.offsets "offsets"
array, at the exact offset described for them. In particular, if two or more
tiles overlap, the image with higher index in the
@ref AVStreamGroupTileGrid.offsets "offsets" array takes priority.
Note that a single image may be used multiple times, i.e. multiple entries
in @ref AVStreamGroupTileGrid.offsets "offsets" may have the same value of
idx.

The following is an example of a simple grid with 3 rows and 4 columns:

+---+---+---+---+
| 0 | 1 | 2 | 3 |
+---+---+---+---+
| 4 | 5 | 6 | 7 |
+---+---+---+---+
| 8 | 9 |10 |11 |
+---+---+---+---+

Assuming all tiles have a dimension of 512x512, the
@ref AVStreamGroupTileGrid.offsets "offset" of the topleft pixel of
the first @ref AVStreamGroup.streams "stream" in the group is "0,0", the
@ref AVStreamGroupTileGrid.offsets "offset" of the topleft pixel of
the second @ref AVStreamGroup.streams "stream" in the group is "512,0", the
@ref AVStreamGroupTileGrid.offsets "offset" of the topleft pixel of
the fifth @ref AVStreamGroup.streams "stream" in the group is "0,512", the
@ref AVStreamGroupTileGrid.offsets "offset", of the topleft pixel of
the sixth @ref AVStreamGroup.streams "stream" in the group is "512,512",
etc.

The following is an example of a canvas with overlapping tiles:

+-----------+
|   %%%%%   |
|***%%3%%@@@|
|**0%%%%%2@@|
|***##1@@@@@|
|   #####   |
+-----------+

Assuming a canvas with size 1024x1024 and all tiles with a dimension of
512x512, a possible @ref AVStreamGroupTileGrid.offsets "offset" for the
topleft pixel of the first @ref AVStreamGroup.streams "stream" in the group
would be 0x256, the @ref AVStreamGroupTileGrid.offsets "offset" for the
topleft pixel of the second @ref AVStreamGroup.streams "stream" in the group
would be 256x512, the @ref AVStreamGroupTileGrid.offsets "offset" for the
topleft pixel of the third @ref AVStreamGroup.streams "stream" in the group
would be 512x256, and the @ref AVStreamGroupTileGrid.offsets "offset" for
the topleft pixel of the fourth @ref AVStreamGroup.streams "stream" in the
group would be 256x0.

sizeof(AVStreamGroupTileGrid) is not a part of the ABI and may only be
