webrtc demos

[Pascal Jacquemart]

Hi Fabio,

First of all it could be a bandwidth problem.
Because the GStreamer implementation does not do adaptive streaming. In general your RTSP camera will try to use much more bandwidth than the videotestsrc (even for the same resolution).

Also I think RSTP and WebRTC are both using RTP but in slightly different ways. So you might need to add rtph264depay ! rtph264pay to make it work. You can try to dump the SDP offer in both case to compare.

No idea about your problem on ARM.
