[SOLVED] Hardware video acceleration: iHD_drv_video.so init failed

auspicacious · 2022-12-07 09:52:57

Hello,

I have a new Arch Linux install, running Wayland and KDE.

The system has a i7-1250U (Alder Lake) with embedded Iris Xe (Gen 12.2) graphics.

Graphics acceleration appears to be working correctly. However, following the wiki instructions, I have not been able to get hardware video acceleration working.

Things I have done:

Installed intel-media-driver and libva-utils
Enabled GuC/HuC firmware loading by setting i915.enable_guc=3 and validating that firmware is loaded by checking dmesg output. This is not mentioned on the "Hardware video acceleration" page, but the "Intel graphics" page seems to suggest this might be necessary.
Noted that at the bottom of the Intel graphics page there is a very recent dispute over whether it is necessary to disable the CONFIG_DRM_I915_CAPTURE_ERROR kernel option for hardware video acceleration to work. I have not tried recompiling my kernel to disable this option.

This is the output I get running vainfo:

$ vainfo
Trying display: wayland
libva error: /usr/lib/dri/iHD_drv_video.so init failed
vaInitialize failed with error code -1 (unknown libva error),exit

In mpv, I get a similar error:

mpv --hwdec=auto --gpu-context=wayland video.mkv 
 (+) Video --vid=1 (*) (vp9 950x720 25.000fps)
 (+) Audio --aid=1 (*) (aac 2ch 44100Hz)

Is there something I might have missed? I tried the old intel-libva-driver just in case as well, and received a similar error message. Is there a package that might be missing, or any way to get more debugging information? Thank you.

# pacman -Fy iHD_drv_video.so

Yes, the file does exist at the location libva is looking for it.

Can you try this from intel/media-driver issue on GitHub?

Furthermore, please also have a look here.

Thank you for the pointers -- you made me look more closely at the intel-gmmlib and intel-media-driver packages. I realized that they are both several months out of date.

I built my own intel-media-driver package based on the latest release (22.5.4). I did not (yet) rebuild intel-gmmlib.

It looks like updating intel-media-driver alone was enough to fix it:

$ vainfo
Trying display: wayland
vainfo: VA-API version: 1.16 (libva 2.16.0)
vainfo: Driver version: Intel iHD driver for Intel(R) Gen Graphics - 22.5.4 ()
vainfo: Supported profile and entrypoints
      VAProfileNone                   : VAEntrypointVideoProc
      VAProfileNone                   : VAEntrypointStats
      VAProfileMPEG2Simple            : VAEntrypointVLD
etc.

mpv and intel_gpu_top also work as expected.

I'm new to Arch and couldn't find this information with a quick search: is there an easy way I can submit a patch to move along the update of these packages (although I realize the maintainer may need to do more than that to safely release)?

Thanks again.

As this is not a "package is outdated" but a "doesn't work" issue, you can submit a bug:
https://bugs.archlinux.org/newtask?proj … ER+SUMMARY

It's also possible that the package needed a mere rebuild (not a version update) against the newer libva or libpciaccess packages (which should be fixable much quicker)

Thank you for setting that up for me, I've submitted a bug report:
