pointer to the picture/channel planes.

This might be different from the first allocated byte

Some decoders access areas outside 0,0 - width,height, please see avcodec_align_dimensions2(). Some filters and swscale can read up to 16 bytes beyond the planes, if these filters are to be used, then 16 extra bytes must be allocated.

NOTE: Except for hwaccel formats, pointers not needed by the format MUST be set to NULL.

Examples:

decode_audio.c, decode_video.c, demuxing_decoding.c, encode_audio.c, encode_video.c, filtering_audio.c, filtering_video.c, hw_decode.c, muxing.c, qsvdec.c, transcode_aac.c, and vaapi_encode.c.

For video, size in bytes of each picture line.

For audio, size in bytes of each plane.

For audio, only linesize[0] may be set. For planar audio, each channel plane must be the same size.

For video the linesizes should be multiples of the CPUs alignment preference, this is 16 or 32 for modern desktop CPUs. Some code requires such alignment other code can be slower without correct alignment, for yet other it makes no difference.

Note

The linesize may be larger than the size of usable data – there may be extra padding present for performance reasons.

Examples:

decode_video.c, demuxing_decoding.c, encode_video.c, filtering_video.c, hw_decode.c, muxing.c, and qsvdec.c.

pointers to the data planes/channels.

For video, this should simply point to data[].

For planar audio, each channel has a separate data pointer, and linesize[0] contains the size of each channel buffer. For packed audio, there is just one data pointer, and linesize[0] contains the total size of the buffer for all channels.

Note: Both data and extended_data should always be set in a valid frame, but for planar audio with more channels that can fit in data, extended_data must be used in order to access all channels.

Examples:

demuxing_decoding.c, filter_audio.c, and transcode_aac.c.

reordered opaque 64 bits (generally an integer or a double precision float PTS but can be anything).

The user sets AVCodecContext.reordered_opaque to represent the input at that time, the decoder reorders values as needed and sets AVFrame.reordered_opaque to exactly one of the values provided by the user through AVCodecContext.reordered_opaque

AVBuffer references backing the data for this frame.

If all elements of this array are NULL, then this frame is not reference counted. 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.

For planar audio which requires more than AV_NUM_DATA_POINTERS AVBufferRef pointers, this array will hold all the references which cannot fit into AVFrame.buf.

Note that this is different from AVFrame.extended_data, which always contains all the pointers. This array only contains the extra pointers, which cannot fit into AVFrame.buf.

This array is always allocated using av_malloc() by whoever constructs the frame. It is freed in av_frame_unref().

AVBufferRef for free use by the API user.

FFmpeg will never check the contents of the buffer ref. FFmpeg calls av_buffer_unref() on it when the frame is unreferenced. av_frame_copy_props() calls create a new reference with av_buffer_ref() for the target frame's opaque_ref field.

This is unrelated to the opaque field, although it serves a similar purpose.

AVBufferRef for internal use by a single libav* library.

Must not be used to transfer data between libraries. Has to be NULL when ownership of the frame leaves the respective library.

Code outside the FFmpeg libs should never check or change the contents of the buffer ref.

FFmpeg calls av_buffer_unref() on it when the frame is unreferenced. av_frame_copy_props() calls create a new reference with av_buffer_ref() for the target frame's private_ref field.
