Requirements for Media Source Extensions v2

[chrisn]

The Media Working Group is gathering requirements for the next version of Media Source Extensions (see minutes from the WG's June 9th meeting).

If you have feature requests, use cases, requirements, or other general API improvements for MSE v2, please raise issues against the MSE spec, or comment on existing open issues there (see issue tracker).

You are also welcome to discuss in this thread, and the M&E IG will convey any requirements to the Media Working Group.

Please see the following MSE update from @wolenetz regarding Web Codecs compatible encoded media and MSE (w3c/media-source#184):

I have created an explainer for supporting buffering containerless WebCodecs encoded media chunks with MSE for low-latency buffering and seekable playback.

Please take a look: https://github.com/wolenetz/mse-for-webcodecs/blob/main/explainer.md
Please post any feedback at w3c/media-source#184 as early as you can, as I intend to prototype this in Chromium (https://www.chromestatus.com/features/5649291471224832).

I recommend taking a look at the use cases, and the list of open questions in the explainer. In particular, do MEIG members have use cases where feeding decoded, rather than encoded, media to MSE source buffers is needed (currently out of scope)?

Closing this, as we have a separate issue for MEIG discussion on MSE, see #6.
