Description
Support for configuration of AV1 Screen Content Coding Tools in WebCodecs has been added to the AV1 Registration page, along with per-frame QP support. The Chromium tracking bug is here: https://bugs.chromium.org/p/chromium/issues/detail?id=1464862
As shown in the graph included with the tracking bug, configuration of AV1 screen content coding tools appears to be effective.
The functionality ended up being part of contentHint (#274) so this has been overtaken by events.
Might defer to @youennf or @jyavenard...
@aboba, can you clarify whether the ask is for https://w3c.github.io/webcodecs/av1_codec_registration.html#dom-videoencoderencodeoptionsforav1-quantizer or for https://w3c.github.io/webcodecs/av1_codec_registration.html#dom-av1encoderconfig-forcescreencontenttools? If the latter, can we safely close this issue or should we wait for https://github.com/w3c/webcodecs/pull/752 resolution?
