#837: WebRTC-SVC (Scalable Video Coding)

Visit on Github.

Opened Apr 25, 2023

I'm requesting a TAG re-review of WebRTC Scalable Video Coding.

WebRTC Scalable Video Coding allows to use the capabilities of modern video codecs to combine several video quality into a single encoded stream sent via WebRTC to an endpoint that can then dispatch the right substream to the different parties based on their receiving capabilities.

Further details:

  • I have reviewed the TAG's Web Platform Design Principles
  • Relevant time constraints or deadlines: [please provide]
  • The group where the work on this specification is currently being done: W3C WebRTC Working Group
  • Major unresolved issues with or opposition to this specification: N/A

You should also know that there was a previous review of this specification 4 years ago: https://github.com/w3ctag/design-reviews/issues/396

We'd prefer the TAG provide feedback as (please delete all but the desired option):

🐛 open issues in our GitHub repo for each point of feedback

Dan: Dom was asking for a eta

Tess: only major change.. sounds like a good thing.

Dan: we reviwed media capabilities - satisfied with concerns. Concerns were that it was already shipping. Multistakeholder?

Tess: I think it has wider support

Dan: supported across all browsers according to MDN - data maintained by Open Web Docs - thank you Open Web Docs.

Tess: need to verify what they've said is the only substantive change.... doing a diff, looks like every word in the spec has changed. Could be editorial, but difficult to confirm the assertion that only one thing changed.

<blockquote> Hi folks -

Thanks for sending us this review. Given what @adoba wrote above concerning the changes and the fact that Media Capabilities API itself enjoys multi-stakeholder support, we'd like to close this review. However, it looks to us like a lot of additional changes were made to the spec. @dontcallmetom can you confirm that this is the only substantive change?

Dan: dom got back to us.

Dan: I asked Dom about the dependency on the media capabilities API.. it looked like a lot of changes... Dom said it isn't the only substantive change, but probably the most impactful one. List of PRs seems fine. Good to close?

Tess: yes I'm not worried about anything in that list.

Rossen: close now?

Dan: Happy to close now.
