The line below is in the output:

[RDD 112308: MediaSupervisor #4]: D/PlatformDecoderModule FFVPX: VAAPI is disabled by parent decoder module.

Expected results:

The video engine should be used, as it’s done with H264 and playing the same VP8 file with mpv on commend line.

VP8 decoding still works with firefox 110.0.1-1.

The Bugbug bot thinks this bug should belong to the 'Core::Audio/Video: Playback' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

If this issue is on Nightly, it will be fixed in bug 1820416.
