The format seems to be well documented - raw RTP frames. Here's even a
tool which can reassemble prober video files from it:

If the format itself is simple enough, and can possibly even be
detected (i.e. identified by looking at it), demuxing support could be
added to ffmpeg. Patch welcome. ;-)

Do you happen to have some samples?
