Hello, you probably meant Intel GPUs, not processors?

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.
