Intel UHD Graphics Hardware Acceleration

[ozzzman]

Hello :D

Anyone have any luck getting Intel UHD hardware accelerated video decoding to work?

I'm currently running Ubuntu 19.10 (Eoan Ermine).
Machine is an HP Envy x360 with Core i5-10210U.

Here's some input/output info:

I have gstreamer1.0-vaapi and libvdpau-va-gl1 installed.

I've tried installing the proprietary i965-va-driver-shaders and intel-media-va-driver-non-free packages (over i965-va-driver and intel-media-va-driver) and switched back again.

I've tried installing the oibaf PPA found here:
https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers
(even tried switching the repository to 20.04 (Focal Fossa) to no avail).

I've also tried installing the upstream 5.4.1 kernel following this as a guide:
https://www.tecmint.com/upgrade-kernel-in-ubuntu/


Nothing seems to work. :confused:

Some web searching found this: https://github.com/Intel-Media-SDK/MediaSDK/wiki/Intel-media-stack-on-Ubuntu which is for 19.04 and appears to be the repo for Intel.

https://wiki.ubuntu.com/IntelQuickSyncVideo says:

If your CPU is Broadwell (5th gen) or older then disable 4K/VP9 support (to stop it from reverting to software playback): Create a configuration file .config/mpv/mpv.conf in your home directory that explicitly tells mpv to use acceleration and to download only formats that most Intel CPUs can decode in hardware:


hwdec=vaapi
ytdl-format="bestvideo[ext=mp4]+bestaudio[ext=m4a]"

But if your CPU is 7th gen (Kaby Lake) or newer then you probably don't want to do that because it will disable 4K/VP9/HDR support. Skylake systems (6th gen) are somewhere in the middle where the answer is mostly the same as for 7th gen but Skylake does not support HDR (and so would need the above workaround).

Thanks for the help TheFu. I've found another answer.

sudo nano /etc/environment

add syntax:
LIBVA_DRIVER_NAME=iHD
(save and exit)
reboot

Glad you found an answer AND posted it here! Thanks!
Better to use

sudoedit /etc/environment
add syntax:

LIBVA_DRIVER_NAME=iHD
or just edit your own ~/.bashrc file

nano ~/.bashrc Use any editor you like.
add syntax:

export LIBVA_DRIVER_NAME=iHD
While you are in the .bashrc file, might as well add a few other custom lines to specify a better PAGER and EDITOR you prefer.

export PAGER=less
export EDITOR=gedit

less will let us go forwards and backwards while looking at files.
The editor will be used by sudoedit and other tools that honor it as your preferred editor. Beware, if you use ssh logins, then specifying a GUI editor is a bad idea. There are some other options to control the editor depending on the type of login.

I need to find a workable solution for video HW decoding on my 16.04 desktops still. I don't really want anything that needs a PPA. mpv is the main video player here, so don't really need all that much broad support across programs.

Hello all!

Could I ask a kinda stupid question as a newbie I am? I came to this thread since I was trying to find a reason why my model of the GPU is not presented in my system/hardware settings. I have an integrated Intel UHD 620 and wherever i look only the i915 name shows. Mind you that I don't face any flickering issues or anything that can let me think that I don't have hardware acceleration in my system, but behold! I've run the above commands and i was getting the same errors as ozzzman, did what you guys suggested and now i can see the outcome running vainfo.
So my question is this...Should I revert back to the previous state, or just leave the export LIBVA_DRIVER_NAME=iHD as is? Had my system already hardware acceleration?

Much appreciate any reply :)
