Perhaps this is a good time then for me to re-iterate a couple problems we have integrating MediaStreams and PeerConnection. I don't have the answers here, but I would like to toss these up for discussion.
1. We can't currently get the track ID and type directly from a MediaStream of nsDOMMediaStream. We are right now using some content hints put into nsDOMMediaStream to let us know whether there is probably audio and/or video (alder branch), but we don't get track IDs and it all breaks when we want to support creating SDP for multiple audio or video sources. I understand that the type is not known in every case, but it would be great to be able to get more accuracy about the SDP we should be generating. 2. We are currently registering as a MediaStreamListener to get information about tracks that are added after pc->AddStream is called. We are set up to look at every NotifyQueuedTrackChanges() to see if it is a track we haven't already seen and what its type is. I think this might be a problem since NotifyQueuedTrackChanges gets called very often for each new chuck of data. I think what we need instead is some way to be notified only when a track is added or removed, such as a new method on listener. That would give us notification on track removal as well. -EH On Sun, Jul 22, 2012 at 4:15 PM, Robert O'Callahan <[email protected]> wrote: > I've been acting as decision-maker of last resort for many video-related > issues, especially those related to codec integration and media playback, > and that is neither necessary nor desirable.
