[vlc] Does VLC handle H.263 video over RTP?

[Pedro Sanchez]

Hello,

I'm trying to get VLC to decode a H.263 video stream that comes over
RTP. The video server offers two tracks, one for audio and one for
video. VLC only requests to play the audio track and ignores video. Is
there something special that has to be present in the offered SDP for
VLC to send the SETUP and PLAY commands to the video server?

I'm using VLC 0.8.6 on both XP and Linux with identical results. For
your reference, I attach the RSTP negotiation that takes between VLC and
the video server.

Thanks,
