The tarball for x11-libs/libva-intel-media-driver-20.2.0 has in its CMakeLists.txt file the ability for it to create an intel-media.sh file based on media_driver/cmake/linux/intel-media.sh.in which it will install in /etc/profile.d/. Within Gentoo such files should be installed in /etc/env.d. The ebuild for this package does not install such a file. Sample content of this file is: LIBVA_DRIVERS_PATH="/usr/lib64/va/drivers" LIBVA_DRIVERS_NAME=iHD where LIBVA_DRIVERS_PATH should contain $EROOT to include the $EPREFIX. For this reason and that Gentoo's ebuild documentation states that $ROOT needs to be used from within pkg_* functions, this should be done in a new pkg_preinst section, e.g., pkg_preinst() { echo "LIBVA_DRIVERS_PATH=\"${EROOT}/usr/lib64/va/drivers\"" >"${T}"/50vaapi echo "LIBVA_DRIVERS_NAME=iHD" >>"${T}"/50vaapi doenvd ${T}/50vaapi } in the libva-intel-media-driver-20.2.0.ebuild file --or some equivalent (I am not an expert in writing ebuild files). Having the /etc/env.d/50vaapi file installed allows the "vainfo" command (in media-video/libva-utils) to run properly system-wide. Additionally, this helps improve the current mess in trying to get Intel UHD drivers enabled, e.g., https://forums.gentoo.org/viewtopic-t-1110144-start-0.html#8491046 . Reproducible: Always Steps to Reproduce: 1. emerge -av =libva-intel-media-driver-20.2.0 2. emerge -av media-video/libva-utils 3. vainfo Actual Results: vainfo fails if (at least) LIBVA_DRIVERS_NAME is not set. Manually creating a file in /etc/env.d/50vaapi fixes the problem (hence this bug report's fix in the description). Expected Results: Output like this, e.g., libva info: VA-API version 1.8.0 libva info: Trying to open /usr/lib64/va/drivers/iHD_drv_video.so libva info: Found init function __vaDriverInit_1_8 libva info: va_openDriver() returns 0 vainfo: VA-API version: 1.8 (libva 2.8.0) vainfo: Driver version: Intel iHD driver for Intel(R) Gen Graphics - 20.2.0 () vainfo: Supported profile and entrypoints VAProfileNone : VAEntrypointVideoProc VAProfileNone : VAEntrypointStats VAProfileMPEG2Simple : VAEntrypointVLD VAProfileMPEG2Simple : VAEntrypointEncSlice VAProfileMPEG2Main : VAEntrypointVLD [snip]
Actually environment variable LIBVA_DRIVERS_NAME overrides automatic selection and is not required. Tested on two boxes with Intel CPU, no LIBVA_DRIVERS_* vars are set. For PC with Kuby Lake R CPU, with both libva-intel-media-driver and libva-intel-driver installed: # vainfo libva info: VA-API version 1.9.0 libva info: Trying to open /usr/lib64/va/drivers/iHD_drv_video.so libva info: Found init function __vaDriverInit_1_9 libva info: va_openDriver() returns 0 vainfo: VA-API version: 1.9 (libva 2.9.0) vainfo: Driver version: Intel iHD driver for Intel(R) Gen Graphics - 20.3.0 () vainfo: Supported profile and entrypoints VAProfileNone : VAEntrypointVideoProc ....

Results for libva 2.8.0 are similar, except that libva doesn't try i965 for Comet Lake CPU. It's clear that libva tries to automatically load the best available driver without any environment variable. However it worth to check that no intel-media.sh file is installed in profile.d. I'll do it.
I've added the patch to allow override automatic detection of VA driver by USE flag. Also added cmake parameter to ensure that 'intel-media.sh' will not be installed. https://github.com/gentoo/gentoo/pull/18946
