1723540 - Video output is green with SW-WR and VAAPI

Status: RESOLVED FIXED

(Core :: Audio/Video: Playback, defect, P3)

Description

[Robert Mader [:rmader]]

We currently allow VAAPI/DMABUF decoding with Webrender - also Software Webrender, even though it can't handle it and fails in https://searchfox.org/mozilla-central/source/gfx/wr/webrender/src/renderer/mod.rs#4179

Disable hardware video decoding when SW-WR is used.

Getting this out of media triage queue -- though it looks like will be resolved soon by in flight patch. Please adjust values if needed.

To trigger this issue, users need to enable at least two non-default settings (EGL backend, either through Wayland or X11-EGL, and media.ffmpeg.vaapi.enabled). Thus reducing the priority - it's probably still too high.
