[transition] FPWD Request for Media Source Extensions

FPWD Request for Media Source Extensions
from https://github.com/w3c/transitions/issues/382

# Document title, URLs, estimated publication date
- Title: Media Media Source Extensions™
- URL: https://w3c.github.io/media-source/
- Shortname: media-source (no specific versioning planned, goal is simply to have /TR/media-source target the FPWD. I will add a link to the previous Recommendation in the front matter)
- Estimated publication date: Tuesday 28 September 2021

# Abstract
This specification extends HTMLMediaElement [HTML] to allow JavaScript to generate media streams for playback. Allowing JavaScript to generate streams facilitates a variety of use cases like adaptive streaming and time shifting live streams. 

(I just noticed that the Abstract section appears after the SOTD section in the ED. I'll fix that before publication)

# Status
This section describes the status of this document at the time of its publication. Other documents may supersede this document. A list of current W3C publications and the latest revision of this technical report can be found in the W3C technical reports index at https://www.w3.org/TR/.

On top of editorial updates, substantives changes since publication as a W3C Recommendation in November 2016 are the addition of a changeType() method to switch codecs, the possibility to create and use MediaSource objects off the main thread in dedicated workers, and the removal of the createObjectURL() extension to the URL object following its integration in the File API [FILEAPI]. For a full list of changes done since the previous version, see the commits.

The working group maintains a list of all bug reports that the editors have not yet tried to address.

Implementors should be aware that this specification is not stable. Implementors who are not taking part in the discussions are likely to find the specification changing out from under them in incompatible ways. Vendors interested in implementing this specification before it eventually reaches the Candidate Recommendation stage should track the GitHub repository and take part in the discussions.

This document was published by the Media Working Group as a First Public Working Draft. This document is intended to become a W3C Recommendation.

GitHub Issues are preferred for discussion of this specification.

Publication as a First Public Working Draft does not imply endorsement by the W3C Membership.

This is a draft document and may be updated, replaced or obsoleted by other documents at any time. It is inappropriate to cite this document as other than work in progress.

This document was produced by a group operating under the W3C Patent Policy. W3C maintains a public list of any patent disclosures made in connection with the deliverables of the group; that page also includes instructions for disclosing a patent. An individual who has actual knowledge of a patent which the individual believes contains Essential Claim(s) must disclose the information in accordance with section 6 of the W3C Patent Policy.

This document is governed by the 15 September 2020 W3C Process Document.
