[Mp4-tech] H.263 Parsing

[Joshi]

Hi,
Does anybody know how to parse the H.263 Elementary
Stream Data?  I need to know the boundaries where GOB
(Group of Block) and MB (Macro Block) Occurs in it.
Anybody who has worked on this pls let me know.  It is
bit urgent for me.
Is there any open source parser for H.263 available
other than ffmpeg.  Do pls let me know asap!
Regards,
Joshi
