This leads to ambiguity in the track default kind/language/label algorithms when multiple defaults with the same type and byteStreamTrackID are present. I propose that step 1 in the constructor be changed to the following: "If trackDefaults contains two or more TrackDefault objects with the same type and the same byteStreamTrackID, then throw an INVALID_ACCESS_ERR and abort these steps." This should cover the original empty string case and prevent the ambiguous situation as well. 114531 1 acolwell 2014-11-04 23:16:07 +0000 Change committed... https://dvcs.w3.org/hg/html-media/rev/0a76ec601ebf
