1807762 - [Snap] AV1 HW acceleration unsupported on Firefox Ubuntu 22.10 snap

Status: RESOLVED DUPLICATE of bug 1760941

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

Description

[123321artyom]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:109.0) Gecko/20100101 Firefox/109.0

Steps to reproduce:

(All steps are gone through on Intel Tiger Lake i7-1165G7, which supports AV1)

1. Install Firefox Beta snap package on Ubuntu 22.10
2. Launch with (or without, does not matter) MOZ_LOG="PlatformDecoderModule:5" MOZ_DISABLE_RDD_SANDBOX=1
3. Go to https://bitmovin.com/demos/av1 and play the video

Actual results:

libdav1d was used

if you examine the log, the following lines can be seen:

Expected results:

VAAPI should have been used since chipset supports native AV1 playback

[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.

Looks like snap environment is missing some components. Please try mozilla binaries directly:

If it doesn't work please attach the log here.
Thanks.

Thanks for the suggestion.

The tarball firefox build at least tries to use va-api (ffmpeg on ubuntu is old and unpatched, thus crashes), then falls back to libdav1d. It seems that your guess about an issue with the snap environment is right.

Isn't it just a dupe of bug 1760941 and we are just waiting on core22 usage?

Comment 5

[:gerard-majax]

Martin, I have not followed closely the situation regarding how we perform AV1 hardware decoding, but it sounds like a dupe of 1760941, what's your opinion ?

Yes, may be the same.
