Bug 1619258 [Wayland] Enable VA-API for all formats, r?jya
(deleted), text/x-phabricator-request

Details

Implement HW decode of VP9 format by VA-API. Also check if that's faster than SW decode.

Assignee: nobody → stransky
Status: NEW → ASSIGNED

Jean, I'd like to go with this simplified version of vp9 HW support and implement the in-tree ffmpeg enhancement in a different bug.

is any chance that this patch squeeze into mozilla75 ?

Since it's disabled by default and h264 only VAAPI can be lightly confusing for these who enable experimental VA-API support (and try youtube without h264ify plugin), backporting this patch could speed-up testing process of this feature.

https://nightly.mozilla.org should be used for VAAPI testing as there are still other VAAPI, WebRender and Wayland bugs.

Thanks, of course! Compiling _beta5 with cherry-picked deferencing fix and VP9 VA-API. I'll report how well it (does/doesn't) work :)

For h264 is it enough, but for VP9 probably some patch must be missing. I'm having these two patches applied:

Bug 1619258 [Wayland] Enable VA-API for all formats, r=jya
Bug 1622729 - Use the appropriate level of indirection when calling av_freep in FFmpegVideoDecoder. r=jya

For vp9 you need to disable media.ffvpx.enabled temporarily (bug 1623584 comment 20). If it does not work with https://nightly.mozilla.org, please see bug 1610199 comment 45.

Beta/Release Uplift Approval Request

  • User impact if declined: va-api will support h264 decoding only.
  • Is this code covered by automated tests?: No
  • Has the fix been verified in Nightly?: Yes
  • Needs manual test from QE?: No
  • If yes, steps to reproduce:
  • List of other uplifts needed: None
  • Risk to taking this patch: Low
  • Why is the change risky/not risky? (and alternatives if risky): Linux/Wayland only. Just removes a restriction we had for initial implementation. Functionality was confirmed by users (https://bugzilla.mozilla.org/show_bug.cgi?id=1623584#c21)
  • String changes made/needed: none

This looks like something that should ride the trains.

I am looking for a way to enable vaapi for vp9 on firefox at plasma wayland, and I found this bug report. Interestingly, but I still cannot get vaapi to work for vp8 and vp9 in plasma wayland, whereas h264 works fine.

I am using firefox 95, have media.ffmpeg.vaapi.enabled on and media.ffvpx.enabled off.

I can play the youtube video using mpv with vaapi enabled.

Here is my output of vainfo

(In reply to Chang Liu from comment #12)
This feature is still experimental and undergoes changes.
Ideally, please test VAAPI only with https://nightly.mozilla.org - at least until you have Firefox 97.
No hacks are needed anymore as of Firefox 97 (bug 1698778 was fixed in 96, bug 1743926 was fixed in 97), VAAPI is properly sandboxed and you just need to set media.ffmpeg.vaapi.enabled and media.rdd-ffmpeg.enabled to true.
If there is a VAAPI bug in Nightly that is not yet tracked by bug 1610199, please file a new bug: https://bugzilla.mozilla.org/enter_bug.cgi?product=Core&component=Audio%2FVideo%3A%20Playback

I just checked and confirmed it is working in Firefox 97. Thanks for your reply.

For firefox 95 you need to disable RDD, i.e. set media.rdd-process.enabled to false.
