It would help if I could see the initial offer/answer as well (this
looks like a renegotiation to me). There may be some bug in multiple
bundle groups and renegotiation.

Hi,
Does Firefox supports multple BUNDLEs ? I have the following case. Three WebRTC
peers are connected via media server.
Audio and video multistreamed in two channels : one for all peers audio, second
- for all the video.
I have two nominated ICE connection, oprt 8000 for audio, 9000 - video.
Remote part is offer and has two BUNDLE groups. And when I'm calling
createAnswer for local SDP, I see
that the second audio m-line assigns local port 51818 which concerns to the
video channel.
Both video m-lines show "9" which I can't reconginze at all.
If I mungle the sdp before setLocalDescription to have needed ports (51816 for
audio and 51818 for video), the resulting SDP
after that contains only two m-lines - one audio and one video. Which is
incorrect because differs from offer SDP by count,
and both videos from the peers is occasionally shown in the same video spot.
Have I done something wrong or Firefox was not tested in such a case ?
