Hello TAG!

I'm requesting a TAG review of the proposed WebRTC 1.1 extension:

• Name: PlayoutDelayHint
• Specification URL: w3c.github.io/webrtc-extensions/#dom-rtcrtpreceiver-playoutdelayhint
• Explainer, Requirements Doc, or Example code: discourse.wicg.io/t/hint-attribute-in-webrtc-to-influence-underlying-audio-video-buffering/4038
• Tests: Blink wpt test.
• Primary contacts: kuddai@webrtc.org, minyue@webrtc.org, hbos@webrtc.org

Further details:

• I have read and filled out the Self-Review Questionnare on Security and Privacy. The assessment is here.
• I have reviewed the TAG's API Design Principles

You should also know that:

• To have the context on the current state of WebRTC 1.0 please refer to the webrtc-pc spec.
• webrtc-extensions spec describes multiple WebRTC 1.1 extensions. Here, we are requesting review only for the playoutDelayHint extension.
• Chrome implemented it starting from M79.
• It is designed similarly to the AudioContextOptions latencyHint option.

We'd prefer the TAG provide feedback as (please select one):

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