Steps to reproduce:

2.ps: detail information (debug log) in the attachment


Actual results:

audio/video SSRC in the RTP also changes, while audio/video SSRC in the SDP doesn't change. 


Expected results:

we hope SSRC both in RTP and SDP doesn't change anyway.

Please give more information about what occurred (SDP from both sides, and if possible contents of about:webrtc) and what seems to cause the change.  I tried a local call, and compared the local SDP with a wireshark capture, and the video SSRC matched the SSRC in one of the outgoing streams.

Have you verified with a wireshark capture?  (i.e. is it a problem with the stats code)

I'm having no luck reproducing this with our renegotiation mochitests. No unexpected SSRCs are showing up in either the RTP or the stats.
To the reporter - Please see comment 1 and comment 2.  We can't repro and  need additional information.  Without additional info, I'll need to close this bug as incomplete.

Closing, as we don't have enough information to move this forward.
