RTP/SAVPF <-> RTP/AVP bridging #287

Closed mjhubert closed 7 years ago

mjhubert commented 7 years ago

Hi,

We are trying to accomplish communication between a WebRTC agent and a custom agent build with GStreamer running on a Raspberry Pi.

WebRTC <--[RTP/SAVPF]--> RTPEngine <--[RTP/AVP]--> GStreamer

On the WebRTC end have receive the video correctly but on the other end we see nothing or only for a few seconds and then it freezes.

Below is the rtpengine log, is there a problem in our offer/answer?

Thanks!

Can you use RTP/AVPF (ie enable RTCP feedback messages) on the GStreamer side? WebRTC depends on the use of RTCP feedback messages and video generally doesn't work if the other side doesn't send any.

mjhubert commented 7 years ago

Thanks, we will look into that. May be the documentation should be changed: "Arbitrary bridging between any of the supported RTP profiles (RTP/AVP, RTP/AVPF, RTP/SAVP, RTP/SAVPF)"

Because there are combination that will not work, so "arbitrary" bridging is not possible.

rfuchs commented 7 years ago

It's not a problem with the bridging capability. The problem is the video codec relying on the feedback mechanism, and so the RTP profile to be used must include that mechanism obviously.
