Review group milestones

[tidoust]

The Media WG's charter happily asserts that all specifications developed by the group will be published as Candidate Recommendations (CR) by the end of 2020. I'm raising this issue to track the publication status of the group's deliverables, and discuss an updated timeline:

• Media Capabilities: Some open issues that still need to be addressed. Which ones prevent publication of the spec as CR?
• Picture-in-Picture: Publication as CR is tracked in disablePictureInPicture interoperability picture-in-picture#184. Could a CR be published soon?
• Media Session: There are open issues to address. What is a reasonable updated timeline for the spec?
• Media Playback Quality: The open question is rather on whether to publish the spec as a standalone spec or to merge it within HTML, tracked in Move Media Playback Quality to FPWD or to HTML specification? #17.
• Autoplay Policy Detection: The group has not discussed this deliverable recently. Does it still plan to work on it?
• Media Source Extensions / Encrypted Media Extensions: Good progress on flagging issues. Some updates have made it to the specs, other updates have not. It would be good to publish the revisions as First Public Working Draft (FPWD).

I note that Process 2020 (under which the group now operates) makes it easier to iterate at the CR phase: no need to get back to Working Draft after publication of an initial CR, the group can just publish new CR Drafts whenever needed (without having to get approval from the Director, and regardless of whether the new drafts introduce normative changes).

It would be good to review milestones again to re-charter the group, in particular to set expected completion dates and/or re-assess intent for each of the deliverables.

Refreshing previous comment from December 2020:

• Media Capabilities: Some open issues that still need to be addressed. Which ones prevent publication of the spec as CR?
• Picture-in-Picture: Publication as CR is tracked in disablePictureInPicture interoperability picture-in-picture#184. Could a CR be published soon?
• Media Session: There are open issues to address. What is a reasonable updated timeline for the spec?
• Media Playback Quality: We're still looking for a volunteer to have the spec merged in HTML, tracked in Move Media Playback Quality to FPWD or to HTML specification? #17.
• Autoplay Policy Detection: The group has resumed work on the spec and published it on the Recommendation track. What milestones can we set?
• Media Source Extensions: New version of the spec was published on the Recommendation track with changeType(), worker support, and without createObjectURL() following its integration in the File API. Next steps?
• Encrypted Media Extensions: Spec still has not been published as First Public Working Draft (FPWD).
• WebCodecs: Lots of progress on the spec, published on the Recommendation track, associated registries and registration specs. What realistic milestones can we set for the spec?
• Audio Focus: Just adopted by the Working Group. Time to First Public Working Draft?
