Details

The current MoofParser implementation only deals with one track at a time. It needs to be separated out to parse multiple tracks.
Is this the bug that would address the known issue here:

Saying:

  "Browsers have trouble with more than one audio track in a video (for multi-language support): IE 11 supports it, Firefox plays the last track, Chrome plays the first track."

Ah, I suspect it's this one: https://bugzilla.mozilla.org/show_bug.cgi?id=1169102

Surprising since MDN includes the following:

Enabling this feature adds the HTMLMediaElement.audioTracks and HTMLMediaElement.videoTracks properties to all HTML media elements. However, because Firefox doesn't currently support multiple audio and video tracks, the most common use cases for these properties don't work, so they're both disabled by default. See Firefox bug 1057233 for more details.
