An AV_PKT_DATA_H263_MB_INFO side data packet contains a number of structures with info about macroblocks relevant to splitting the packet into smaller packets on macroblock edges (e.g.
as for RFC 2190). That is, it does not necessarily contain info about all macroblocks, as long as the distance between macroblocks in the info is smaller than the target payload size. Each MB info structure is 12 bytes, and is laid out as follows: |
AV_PKT_DATA_SKIP_SAMPLES |
Recommmends skipping the specified number of samples.

AV_PKT_DATA_JP_DUALMONO |
An AV_PKT_DATA_JP_DUALMONO side data packet indicates that the packet may contain "dual mono" audio specific to Japanese DTV and if it is true, recommends only the selected channel to be used.
