 Posted: Tue Apr 13, 2021 12:14 pm Post subject: [SOLVED]the right way to install libva-intel-media-driver? |
 |
|
I want to enable VAAPI on my i7-8565U, I read the VAAPI wiki, installed x11-libs/libva, and libva installed x11-libs/libva-intel-driver as a dependency.
But according to this arch wiki https://wiki.archlinux.org/index.php/Hardware_video_acceleration, for HD Graphics series starting from Broadwell (2014) and newer, I should install intel-media-driver, and libva-intel-driver is only for older CPUs.
Why does libva prefers libva-intel-driver over libva-intel-media-driver for newer CPUs when libva-intel-media-driver is already stable?
Can I install x11-libs/libva-intel-media-driver when I already have libva-intel-driver?

Hi
libva-intel-driver is hardcoded into the libva ebuild
| Code: |
PDEPEND="video_cards_nvidia? ( >=x11-libs/libva-vdpau-driver-0.7.4-r1[${MULTILIB_USEDEP}] )
video_cards_nouveau? ( >=x11-libs/libva-vdpau-driver-0.7.4-r3[${MULTILIB_USEDEP}] )
vdpau? ( >=x11-libs/libva-vdpau-driver-0.7.4-r1[${MULTILIB_USEDEP}] )
video_cards_intel? ( >=x11-libs/libva-intel-driver-2.0.0[${MULTILIB_USEDEP}] )
video_cards_i965? ( >=x11-libs/libva-intel-driver-2.0.0[${MULTILIB_USEDEP}] )
utils? ( media-video/libva-utils )
"

This is installed by default when you have USE="vaapi" in make.conf.
Do not emerge it yourself.
What you CAN do is
| Code: |
emerge -av libva-intel-media-driver
echo 'export LIBVA_DRIVER_NAME="iHD"' >> ~/.bashrc
source ~/.bashrc
|
to override the auto use of the default libva-intel-driver

I hope libva doesn't hardcode libva-intel-driver in the future, so that I don't have to install both libva-intel-driver and libva-intel-media-driver. |

| If you get an acceptably working system with only the driver you want, please write up what steps you took and, if you think other users could do those steps readily, file a bug to have the dependencies changed to support this use case. |

Overriding LIBVA_DRIVER_NAME variable is not needed.
in system with x11-libs/libva-intel-driver
| Code: | $ vainfo 2> /dev/null | grep "Driver version"
vainfo: Driver version: Intel i965 driver for Intel(R) Skylake - 2.4.1 |
and with also libva-intel-media-driver
| Code: | $ vainfo 2> /dev/null | grep "Driver version"
vainfo: Driver version: Intel iHD driver for Intel(R) Gen Graphics - 20.4.5 () |

There was a bug in bugs.gentoo.org about changing libva's hard-coded dependency on libva-intel-driver to libva-intel-media-driver for newer intel CPUs.
But now I can't find the bug in "related bugs" of the libva package any more, and the issue is still here. |
