1764477 - In-band color depth changes in VP9 and AV1 don't apply correctly, causing green or magenta output.

Status: RESOLVED FIXED

(Core :: Audio/Video: Playback, defect)

Description

[Zaggy1024]

Attachment: av1_yuv420p_and_yuv420p10.webm

When a keyframe sample in VP9 or a sequence header in AV1 changes the bit depth of the video, the change isn't propagated correctly to the displayed image.

The attached webm file contains two sequences, both .5 seconds long. The first is encoded in yuv420 8-bit, the second in yuv420 10-bit. When playback reaches the second sequence, the video becomes green.

Previously, AsyncImagePipelineManager::UpdateImageKeys did not check bit depth when updating image keys, and WebRenderTextureHost did not correctly wrap GetColorDepth(). This caused the configuration not to correctly update.
