Аппаратное ускорение видео в Linux
Установим правильные драйвера для VA-API и VDPAU.
| VA-API | VPDAU | |
| AMD | libva-mesa-driver | mesa-vpdau |
| Intel | intel-media-driver (Для современных компьютеров, начиная от Broadwell) libva-intel-driver (Для старых от GMA4500 до Coffee Lake) Для декодирования VP8 кодека начиная с Haswell Refresh вплоть до Skylake, также нужно установить intel-hybrid-codec-driver Процессоры начиная со Skylake, также требуют установки linux-firmware | libva-vdpau-driver (Трансляция VA-API) |
| NVIDIA | nvidia-utils | |
Установим «libva-utils» для того, чтобы воспользоваться утилитой «vainfo», которая покажет нам информацию о VA-API:

«VAEntrypointVLD» обозначает, что вы можете декодировать данные кодек, а «VAEntrypointEncSlice», что можете кодировать.
Установим утилиту «vdpauinfo», чтобы протестировать работу VDPAU бекенда
