I can't find the MPEG2 standard anywhere so I'm not able to spec that part.

I've specced the requirements for Ogg, WebM, and MPEG-4. I haven't specced
requirements for DASH, since no proposal for DASH was made.

The patch will be given below.

The UA can only expose tracks in formats it understands how to expose. Tracks
in formats it doesn't understand how to expose obviously can't be exposed,
since it doesn't understand how to expose them.
