This allows to specify a quantizer parameter for each frame for AV1, VP9, and AVC video codecs. The quantizer parameter is set via codec specific extensions for VideoEncoderEncodeOptions. Assuming I know very little about video codecs, what use cases does this enable for developers? Blink component Blink>Media>WebCodecs TAG review None. Previously WebCodecs API had TAG review as a whole: https://github.com/w3ctag/design-reviews/issues/612 This is a new addition since that review, but it's a trivial addition (IMHO) so a new review request isn't needed. I agree, I don't see anything particularly contentious in the proposal that would warrant a full review. TAG review status Not applicable Risks Interoperability and Compatibility Gecko: Neutral (https://github.com/mozilla/standards-positions/issues/837#issuecomment-1614666364) Paul Adenot (Mozilla) expressed that minor changes to WebCodecs spec don't need to go through the full "Request for Mozilla Position" process assuming they were approved by the Media Working Group. WebKit: Positive (https://www.w3.org/2023/03/07-mediawg-minutes.html#t02) The issue was discussed on 07 March 2023 by w3c Media working group. Jer Noble (Apple) was actively participating and provided input for spec details. Can we request a formal position from WebKit, at least to let them know we're intending to ship? Web developers: Positive (https://github.com/w3c/webcodecs/issues/56) People ask for this on GitHub Other signals: WebView application risks Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications? Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, Chrome OS, Android, and Android WebView)? Yes Is this feature fully tested by web-platform-tests?
