Macro Definition Documentation

IFF_EXTRA_VIDEO_SIZE

#define IFF_EXTRA_VIDEO_SIZE   41

This number of bytes if added at the beginning of each AVPacket which contain additional information about video properties which has to be shared between demuxer and decoder.

This number may change between frames, e.g. the demuxer might set it to smallest possible size of 2 to indicate that there's no extradata changing in this frame.
