[media-source] Support "seamless" cross-codec track switching

wolenetz has just created a new issue for 
https://github.com/w3c/media-source:

== Support "seamless" cross-codec track switching ==
Currently, the minimum interop requirement for A/V tracks is at most 
one of each.
These tracks must conform to the mime-type used to construct their 
SourceBuffer(s).
Consequently, web apps that would like to have "seamless" cross-codec 
(e.g., webm vp9->h264 avc->webm vp8) transitions within the same media
 timeline must polyfill and depend on event delivery/timers  to 
approximate a best-effort transition across these using multiple 
MediaSource objects swapped in as media element src.

This issue is opened to understand:
1) more details of what web authors need around this use case, and
2) how the MSE spec might need to be adjusted to enable this use case.
