Hi all,I try to receive H264 stream using WebRTC on FF 33 beta. However, no video is displayed. And I find something weird clues on about:webrtc ... Decoder: Avg. bitrate: 0.00 Mbps (0.00 SD) Avg. framerate: 0.00 fps (0.00 SD) Discarded packets: 0 Local: 17:48:02 GMT+0800 inboundrtp SSRC: 0 Received: 17622 packets (6785.22 Kb) Lost: undefined Jitter: undefined In my case, my sdp constraint is "{'mandatory': {'OfferToReceiveAudio': true, 'OfferToReceiveVideo': true}}", so I will only receive video stream from remote client. According the above messages, it seems FF 33 can't decode H264 stream successfully?
I presume from the way you wrote your message that the sending side is something other than Firefox.
Likely something is wrong in the packets (payload type, mark bits, packetization, etc).
A wireshark capture might help; you can also turn on internal debugs via the Start Debug Logs button on about:webrtc (they'll appear in /tmp (mac/linux) or %TEMP% (windows)).
File a bug in bugzilla (in Core::WebRTC) and attach the logs and a Select-All/Copy of the about:webrtc info, and details of what is generating the stream
NOTE: if by "receive an H264 stream" you mean streaming video (not RTP video encrypted with DTLS-SRTP by a WebRTC client or server), then it will not work, and shouldn't be expected to work.
