[FFmpeg-user] convert/replay H263 raw file Form rtp payload

[Manfred Ehgartner]

I am currently working in a project, where I have pcaps containing h263 and
h264 rtp streams. I don't have any signaling, SDP info, just the rtp streams
and I need to create something playable out oft it. For H264 I succeeded
using videosnarf. The output raw file of videosnarf could be converted to a
MPEG or avi file using ffmpeg. Unfortunately, videosnarf doesn't support
h263, so I tried manually just to dump the rtp payload into some file, but
this couldn't be read by ffmpeg correctly. Also the output oft rtpbreak
(similar tool like videosnarf) couldn't be processed by ffmpeg. So I assume,
videosnarf is not simply dumping the rtp payload to a file. How must the
h263 Payload be modified that the file can be read using ffmpeg? I am happy
about every hint
