HW encoding with VA-API and Intel GPU not working #87

Closed askolsam closed 3 years ago

askolsam commented 3 years ago

Hello.

I cannot get hardware encoding to work using VA-API with Intel GPU in version 26.0.2 (tested both stable and edge). It seems a required file is missing from the snap:

$ obs-studio.vainfo
libva info: VA-API version 1.1.0
libva info: va_getDriverName() returns 0
libva info: Trying to open /snap/obs-studio/1153/usr/lib/x86_64-linux-gnu/dri/i965_drv_video.so
libva info: va_openDriver() returns -1
vaInitialize failed with error code -1 (unknown libva error),exit

$ ls -1 /snap/obs-studio/1153/usr/lib/x86_64-linux-gnu/dri/

The host OS is Fedora 31 and I'm able to use VA-API there just fine (ffmpeg, obs-studio from RPM Fusion repo):

This could be fixed via #88 - it's currently building in launchpad. please look out for a build revision in edge above 1154. Once that lands, please snap refresh obs-studio --edge and see if that works for you.

Fix confirmed (rev 1155).
