Eu não consegui fazer com que o VLC usasse o VA-API na minha máquina e isso está me enlouquecendo!
Estou executando o Arch Linux em um ASUS ZenBook UX305CA com Integrated Intel HD Graphics 515. Instalei libva-intel-driver-1.8.3-1 e vlc-2.2.6-2 .
Quando executo vainfo , obtenho:
libva info: VA-API version 0.40.0
libva info: va_getDriverName() returns 0
libva info: User requested driver 'i965'
libva info: Trying to open /usr/lib/dri/i965_drv_video.so
libva info: Found init function __vaDriverInit_0_40
libva info: va_openDriver() returns 0
vainfo: VA-API version: 0.40 (libva )
vainfo: Driver version: Intel i965 driver for Intel(R) Skylake - 1.8.3

Também a renderização direta está ativada:
glxinfo | grep "direct rendering"
direct rendering: Yes
Tudo parece bem, mas por algum motivo o VLC não fornece os mesmos resultados (eu tenho VA-API video decoder via DRM selecionado nas preferências):

Se eu definir o driver ( export LIBVA_DRIVER_NAME=i965 ) antes de executar o VLC, recebo a seguinte saída:
