Expected results:

VAAPI should be used, and it worked in the past.

[BugBot [:suhaib / :marco/ :calixte]]

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.

Explicitly disabled due to decode corruption (Bug 1790729). You need to set media.navigator.mediadatadecoder_vp8_hardware_enabled to force enable it.

[Martin Stránský [:stransky] (ni? me)]

I see, this is about plain video playback. Will check that.

Comment 6

[Paul Menzel]

Unfortunately, I am unable to comment on the closed bug 1790729 1.

My Webcam does not show any problems with VP8, so it’s a regression, that VP8 acceleration is disabled. It’s also disabled when the Webcam is not used.

1. How can I force enable VAAPI for VP8?
2. People with affected devices, could you please report the bug upstream?
3. Is it possible to detect non-working streams?

(In reply to Paul Menzel from comment #6)

Unfortunately, I am unable to comment on the closed bug 1790729 [1].

My Webcam does not show any problems with VP8, so it’s a regression, that VP8 acceleration is disabled. It’s also disabled when the Webcam is not used.

1. How can I force enable VAAPI for VP8?

Set media.navigator.mediadatadecoder_vp8_hardware_enabled to true at about:config and restart browser. But it applies to WebRTC only, VP8 media clips are played without any restriction.

2. People with affected devices, could you please report the bug upstream?
3. Is it possible to detect non-working streams?

I don't think so. Looks like bad inter frames in the stream, when key frame arrives video is refreshed and fixed.
