CfC: Adopt and Publish FPWD of WebCodecs

Hi all,

Following group discussions during our call in December and exchanges with
the group chairs, W3C team contact, and specification editors, this is a
Call for Consensus (CfC) on adoption of the WebCodecs specification as a
Media WG deliverable and on its publication as a First Public Working Draft
(FPWD).

The specification is available at: https://wicg.github.io/web-codecs/

It defines interfaces for encoding and decoding audio and video. It also
includes an interface for retrieving raw video frames from
MediaStreamStracks. The specification matches the "Encoders/Decoders API"
entry in the Potential Normative Specifications section of the Media WG
charter:
https://www.w3.org/2019/05/media-wg-charter.html#potential-normative

The CfC will last for two weeks and will end on the 14th of February 2021.
Please reply to this email and state one of the following:
 * I support adopting WebCodecs as a Media WG deliverable and publishing it
as a FPWD.
 * I support adopting WebCodecs as a Media WG deliverable but object to
publishing it as a FPWD (please detail your concerns).
 * I object to adopting WebCodecs as a Media WG deliverable (please detail
your concerns)

The specification is currently owned by the Web Platform Incubator
Community Group (WICG). Effective adoption of the specification supposes
that the spec migrates out of WICG. See corresponding Intent to Migrate:

On behalf of the chairs,
-- Mounir
