1552734 - Av1 video playback does not use DXGIYCbCrTextureData for yuv video data

Status: RESOLVED FIXED

Description

Av1 video playback does not use DXGIYCbCrTextureData for yuv video data. On nightly, av1 video was used for youtube video playback on Windows.

In this case, DXGIYCbCrTextureData was not used for yuv video data, instead BufferTextureData was used. RemoteVideoDecoderChild::DeserializeImage() creates RecyclingPlanarYCbCrImage.

Then ImageClient::CreateTextureClientForImage() created BufferTextureData. BufferTextureData could not bound to texture directly. It is not good.

I noticed it during looking into Bug 1552622. Inefficiency of RemoteVideoDecoderChild/RemoteVideoDecoderParent is going to be addressed by Bug 1539043
