1778096 - [Flatpak] VAAPI doesn't work

Status: RESOLVED WORKSFORME

(Core :: Widget: Gtk, defect)

Description

[Pavel Sobolev]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:102.0) Gecko/20100101 Firefox/102.0

Steps to reproduce:

1. Open the about:support page both in the native Firefox and in the Flatpak version.
2. Try to force VAAPI by enabling the media.ffmpeg.vaapi.enabled flag in the Flatpak version.

Actual results:

1. In the VAAPI row I can see

• available by default in the native version;
• disabled by default: VAAPI is disabled by default in the Flatpak version.

2. Forcing VAAPI doesn't make it work either.

Expected results:

It should be available by default in the Flatpak version, since my system supports VAAPI. This can be proved by the native version of Firefox I have alongside.

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

Seems to be fixed in Firefox 104. Either that, or the new amd-gpu-firmware package on the latest Fedora Silverblue fixed it for me.

Never mind, still an issue. Getting blocklisted by env: Blocklisted by gfxInfo in the HARDWARE_VIDEO_DECODING field in about:support.

Is there anything under "Failure log" ? Like VA-API test failed or so?

Huh? I don't see any "Failure log" on that page.

Try 104.x line then.

I'm confused a bit, where should I see this?

Which Firefox version do you run? Is that the latest 104 (or 105 which comes out today)?
If not please try to update to 104 and check the about:support for log message.

The latest Firefox v104. But I don't see the lines you mention.

No, VAAPI is still disabled by default in non-Nightly channels. Just Fedora and Firefox Nightly enable it by default.

I just tested Flatpak Firefox 104.0.2 on Debian Testing with Intel:
Steps:

• $ sudo flatpak install org.freedesktop.Platform.ffmpeg-full/x86_64/21.08
  You need ffmpeg-full for patented H264 and it needs to be of the same version as org.freedesktop.Platform (21.08, VAAPI won't work with 22.08)
• set media.ffmpeg.vaapi.enabled=true and restart Firefox.

Thank you very much for writing this, debug flags especially. VAAPI works now.

So, I did try media.ffmpeg.vaapi.enabled before (as mentioned in the first comment), but it never worked (since v98). Seems like something changed in v104 (since the field was renamed to HARDWARE_VIDEO_DECODING).

This issue is solved.
