1677124 - vaapi not working

Status: RESOLVED WORKSFORME

(Core :: Audio/Video: Playback, defect, P3)

Description

[jpsollie]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:82.0) Gecko/20100101 Firefox/82.0

Steps to reproduce:

play Youtube VP9 video on a Raven ridge APU using Firefox in 4K and 2K mode (using enhanced-h264ify).
Flags to enable VAAPI:
gfx.webrender.all=true
gfx.webrender.compositor=true
gfx.webrender.compositor.force-enabled=true
gfx.webrender.enabled=true
media.ffmpeg.enabled=true
media.ffmpeg.vaapi-drm-display.enabled=true
media.ffmpeg.vaapi.enabled=true
media.ffvpx.enabled=false
media.av1.enabled=false
and run with MOZ_X11_EGL=1 firefox
(the other way around to disable vaapi)

Actual results:

The CPU load for both configurations was exactly the same:
50% for 2k VP9, 200 for 4K VP9

Expected results:

VAAPI should have taken over, decreasing CPU load. The VAAPI state was confirmed to be working using the following command:
ffmpeg -hwaccel vaapi -hwaccel_device /dev/dri/renderD128 -i my_test_h264.mp4 -c:v rawvideo -c:a copy -f matroska - | ffplay -i -
and vainfo shows:
libva info: VA-API version 1.7.0
libva info: Trying to open /usr/lib64/va/drivers/radeonsi_drv_video.so
libva info: Found init function __vaDriverInit_1_7

Martin, would you mind having a look?

small update about this bug:
This Firefox version was installed on gentoo linux.
When enabling wayland support for this package, it offloads vaapi with the options specified above.
installation file is located here: https://gitweb.gentoo.org/repo/gentoo.git/tree/www-client/firefox/firefox-82.0.3.ebuild
Whereas the conflict is solved, requiring wayland support for an X11 setup is definitely ugly.

We need to split dmabuf setup from wayland config. I filed bug 1677855 for it and we welcome any help here, as usual.
