[Libav-user] Is ffmpeg possibe to decode H.263 Mode B?

[Arash Cordi]

normally h263 fragments are as follow:

start of frame --> [Mode A][Mode B] .... [Mode B] <---- end of frame

you only need the first byte of h263 payload header which is the same for
all Mode A,B,C;

+-+-+-+-+-+-+-+-+
|F|P|SBIT |EBIT |
+-+-+-+-+-+-+-+-+


you need timestamp and marker bit (to identify start and end of frame) from
rtp payload.

you also need to align fragments according to SBIT, EBIT in h263 payload
header
