The Chrome Remote Desktop team is looking to support AV1 profile-1 w/ I444 for screen sharing however only I420 is currently supported. This CL adds I444 support for the Dav1dDecoder, which appears to be the preferred decoder and adds profile-1 to the InternalDecoderFactory when the Dav1dDecoder is being used. I've tested this CL using a CRD host w/ I444 enabled and it seems to work as expected, though I've only tested on a debug build so I plan to do some perf testing once this is available in a release build.
