    Question Intel UHD Graphics Hardware Acceleration

    Hello

    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/+archiv...aphics-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.

    Re: Intel UHD Graphics Hardware Acceleration

    Some web searching found this: https://github.com/Intel-Media-SDK/M...tack-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:
    Code:
     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).

    Re: Intel UHD Graphics Hardware Acceleration

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

    sudo nano /etc/environment

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

    Re: Intel UHD Graphics Hardware Acceleration

    Glad you found an answer AND posted it here! Thanks!
    Better to use
    Code:
    sudoedit  /etc/environment
    add syntax:
    Code:
    LIBVA_DRIVER_NAME=iHD
    or just edit your own ~/.bashrc file
    Code:
    nano ~/.bashrc
    Use any editor you like.
    add syntax:
    Code:
    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.
    Code:
    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.
