In a number of places in the MSE spec, a track is added or removed and a simple event fired. For example, step 5.1.5 under 3.5.6 “Initialization Segment Received” currently says: “Queue a task to fire a simple event named addtrack at the AudioTrackList object referenced by the audioTracks attribute on this SourceBuffer object.” The HTML5 media specification has this language for addition of AudioTrack or VideoTracks under 4.8.10.5 “Loading the media resource”: “Fire a trusted event with the name addtrack, that does not bubble and is not cancelable, and that uses the TrackEvent interface, with the track attribute initialized to the new AudioTrack object, at this AudioTrackList object.” Similar trusted event language should be used in MSE. This affects: AddTrack in 3.5.6 Initialization Segment Received (steps 5.1.5, 5.1.7, 5.2.5, 5.2.7, 5.3.5 & 5.3.7) RemoveTrack in 2.2 Methods removeSourceBuffer (steps 5.1.4, 5.1.6, 7.1.4, 7.1.6, 9.1.4 & 9.1.6) 88108 1 jdsmith 2013-05-22 23:25:52 +0000 Paragraph numbers have changed slightly since this was opened.
