http://dxr.mozilla.org/mozilla-central/source/content/media/TrackUnionStream.h?from=trackunionstream&case=true#176 TrackEncoder will receive MediaSegment with zero duration because the segment only carries the TRACK_EVENT_CREATED event. We should filter out this kind of segments instead pending it to vp8/omx encoder?

We handle track end notification in VideoTrackEncoder::NotifyQueuedTrackChanges 184 if (aTrackEvents == MediaStreamListener::TRACK_EVENT_ENDED) { 185 LOG("[VideoTrackEncoder]: Receive TRACK_EVENT_ENDED ."); 186 NotifyEndOfStream(); 187 } For me, it makes sense to handle MediaStreamListener::TRACK_EVENT_CREATED in that function as well

Mass change P2->P3 to align with new Mozilla triage process.
