[media-and-entertainment] Media Source Extensions

chrisn has just created a new issue for https://github.com/w3c/media-and-entertainment:

== Media Source Extensions ==
Work on updating Media Source Extensions has started in the Web Platform Incubator Community Group (WICG). The repository is [here](https://github.com/WICG/media-source).

The feature addition currently in development is support for codec and container switching. Please see the [Intent to Implement](https://groups.google.com/a/chromium.org/forum/#!msg/blink-dev/atNyZDs-WXY/0nZgRGwfBAAJ) and the [explainer](https://github.com/wicg/media-source/blob/codec-switching/codec-switching-explainer.md) for details.

> This feature adds support for improved cross-codec or cross-bytestream transitions in Chrome HTML5 Media Source Extensions playback using a new changeType method on SourceBuffer that allows the type (bytestream and codec(s)) of media bytes subsequently appended to the SourceBuffer to be changed. We are incubating this idea via the WICG, with goal of eventually working with WeMedia Source ExtensionsbPlatformWG to get the result of WICG incubation as part of the next version of the Media Source Extensions API (MSE).

The ReadMe adds further guidance:

> All specification updates that are part of incubation will be done on a per-feature branch off of gh-pages in this repository. Please base your pull-requests accordingly.

> We will use the upstream [w3c/media-source repository's issue tracker](https://github.com/w3c/media-source) for feature discussion beyond pull-requests.

I encourage Interest Group members to review the codec switching changes, and also to suggest other new features as needed.

I suggest that we also review the Interest Group's [own requirements](https://www.w3.org/wiki/HTML/Media_Task_Force/MSE2_Use_Cases) for Media Source Extensions and coordinate submitting these to the MSE issue tracker. This includes previous submissions from [CTA WAVE](https://www.w3.org/wiki/images/8/8c/Mse-eme-v2-use-cases-reqs-wave.pdf) and [Cloud Browser Task Force](https://www.w3.org/wiki/images/4/43/Cbtf-mse2-eme2.pdf).
