Constant AV_PKT_DATA_H263_MB_INFO

pub const AV_PKT_DATA_H263_MB_INFO: u32 = 3; // 3u32

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: @code u32le bit offset from the start of the packet u8 current quantizer at the start of the macroblock u8 GOB number u16le macroblock address within the GOB u8 horizontal MV predictor u8 vertical MV predictor u8 horizontal MV predictor for block number 3 u8 vertical MV predictor for block number 3 @endcode
