You should implement the RTP payload parsing code in libavformat, not in
libavcodec. Libavformat already contains code for RTP parsing (see
libavformat/rtpdec.c and libavformat/rtp_h264.c), but does not
support RFC2190 yet...
You just need to implement the depacketisation code for H.263 and you
are done: the code will be clean and easily maintainable.
