Created attachment 8573387 [details] testcase This testcase usually trips: Assertion failure: outputTrack->GetEnd() == GraphTimeToStreamTime(interval.mStart) (Samples missing), at /builds/slave/m-cen-osx64-d-0000000000000000/build/src/dom/media/TrackUnionStream.cpp:286 It could probably be converted into a more reliable test by turning the 100ms setTimeout into a listener for the correct event.
Jesse, do you know the changeset your build was at ? We've touched this very recently, so it would help narrow down the issues there. Thanks!
