VLC의 하드웨어 비디오 가속

내 컴퓨터에서 VLC가 VA-API를 사용하도록 할 수 없어서 정말 미칠 것 같아요!

저는 Intel HD Graphics 515가 통합된 ASUS ZenBook UX305CA에서 Arch Linux를 실행하고 있습니다. 을 libva-intel-driver-1.8.3-1(를) 설치했습니다 vlc-2.2.6-2.

내가 실행하면 vainfo다음을 얻습니다.

직접 렌더링도 활성화됩니다.

glxinfo | grep "direct rendering"
direct rendering: Yes

모든 것이 괜찮아 보이지만 어떤 이유로 VLC가 동일한 결과를 제공하지 않습니다( VA-API video decoder via DRM기본 설정에서 선택).

VLC를 실행하기 전에 드라이버( )를 설정하면 export LIBVA_DRIVER_NAME=i965다음과 같은 결과가 나타납니다.
