At the F2F meetings in Santa Clara, the HTML WG appeared to support this bug as
well as bug 14492 which requests a change event when tracks are removed. The
combination of bugs 13359 and 14492 should address the needs of the Media
Pipeline task force (MPTF).

The MPTF also supports the idea of a common reference in mapping track
information to specific protocols. CableLabs has produced such a mapping
reference for MPEG2 (http://www.w3.org/Bugs/Public/attachment.cgi?id=1040).
Other mappings should be created for Ogg, WebM, etc.

At the HTML WG meeting in Santa Clara, no consensus was reached on who should
maintain these mapping references.

The resolution suggested by the Media Pipeline task force (MPTF) is the same
one suggested in the original bug report. Here is a link to the MPTF
requirement:
