Let's look into Ubuntu's Mesa: $ dpkg -L mesa-va-drivers (list files from package) <...> /usr/lib/x86_64-linux-gnu/dri/nouveau_drv_video.so /usr/lib/x86_64-linux-gnu/dri/r600_drv_video.so /usr/lib/x86_64-linux-gnu/dri/radeonsi_drv_video.so <...> $ vainfo (from PC with AMD GPU) libva info: VA-API version 1.1.0 libva info: va_getDriverName() returns 0 libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/radeonsi_drv_video.so libva info: Found init function __vaDriverInit_1_1 libva info: va_openDriver() returns 0 vainfo: VA-API version: 1.1 (libva 2.1.0) vainfo: Driver version: Mesa Gallium driver 18.2.2 for AMD KABINI (DRM 2.50.0, 4.18.0-20.3-liquorix-amd64, LLVM 7.0.0) vainfo: Supported profile and entrypoints VAProfileMPEG2Simple : VAEntrypointVLD VAProfileMPEG2Main : VAEntrypointVLD VAProfileVC1Simple : VAEntrypointVLD VAProfileVC1Main : VAEntrypointVLD VAProfileVC1Advanced : VAEntrypointVLD VAProfileH264ConstrainedBaseline: VAEntrypointVLD VAProfileH264ConstrainedBaseline: VAEntrypointEncSlice VAProfileH264Main : VAEntrypointVLD VAProfileH264Main : VAEntrypointEncSlice VAProfileH264High : VAEntrypointVLD VAProfileH264High : VAEntrypointEncSlice VAProfileNone : VAEntrypointVideoProc Here http://linux-hardware.org/index.php?probe=56a2ccc7b4&log=vainfo you may find vainfo from a notebook with Intel GPU. /usr/lib/x86_64-linux-gnu/dri/i965_drv_video.so is used. Let's find out which package it belongs to: $ dpkg -S /usr/lib/x86_64-linux-gnu/dri/i965_drv_video.so i965-va-driver:amd64: /usr/lib/x86_64-linux-gnu/dri/i965_drv_video.so i965-va-driver in Ubuntu is the same as libva-intel-driver in FreeBSD. So, yes, VA-API in Mesa is probably useless on Intel GPUs. Sorry if my outputs from Ubuntu have hurt FreeBSD funs, but I hope they illustrated the question well enough. -- ------ С уважением, Михаил Новоселов | mikhailnov@dumalogiya.ru | https://nixtux.ru
