Error initialising vaapi on Gnome Wayland

[darren-steven]

I know this issue might be broader than just this app, but I think vaapi is working on other apps under wayland (vlc for example)

chromium-vaapi-70.0.3538.77-1.fc29.x86_64.rpm from rpmfusion koji
Hardware Intel Skylake

$ chromium-vaapi
libva error: va_getDriverName() failed with unknown libva error,driver_name=(null)
[22955:22955:1116/104946.418564:ERROR:vaapi_wrapper.cc(328)] vaInitialize failed: unknown libva error

• Defaults to software decoder in youtube

Works fine in Gnome X11 session (I see GPU decoder selected in chrome://media-internals for youtube)

vaainfo reports same info on wayland and X11

$ vainfo
libva info: VA-API version 1.3.0
libva info: va_getDriverName() returns 0

Hello.
Chromium runs through XWayland unlike vlc.
See link

I'm trying my best to compile chromium with wayland ozone but the build is still failing(complaining of a missing vaapi drm file). Unless any of this is solved, chromium on intel wayland won't able to decode in hardware.

Update:
Try Launching Chromium with --use-gl=egl

That flag doesn't make a difference for me

@spicydonuts hmm. Anyway that PR is closed now. The only thing left to do is enabling ozone on chromium.

It is closed, but not merged due to submitter inactivity: intel/intel-vaapi-driver#369 (comment) . It needs to be resubmitted.

@rathann Yes. Also there is a bug report @ Bugzilla. It's been there since Fedora 26

are there still problems with Ozone wayland?

Any update on this issue ?

@mthomos I am providing chromium-ozone binaries for Fedora in copr. These come with vaapi disabled.

For intel vaapi driver there is still need for someone to add support for DRI3.

You can try building your own version of libva-intel-driver using these patches(for now):
1 and 2
