Hi,

I was debugging a issue related to the vaapi on a radeon gpu. And I decided to compare the behavior with an Intel gpu. To my surprise, the intel vaapi wasn't working at all. I couldn't find a solution anywhere, so I'm opening this issue.

You most likely have two VAAPI-capable GPUs on that system.

Provide the output of ls /dev/dri/ to confirm.

Try running:

LIBVA_DRIVER_NAME=i965 vainfo --display drm --device /dev/dri/renderD128

And report back.

Igortorrente commented 1 year ago

Yeah, this is the case. I also have an AMD GPU in my system.

Your command works!

But should be possible to force a specific hardware in the vaapi, right?

Globally, no. Only the library driver variable can be set system wide.

Specific apps, such as ffmpeg, can pick select DRM devices and kernel drivers explicitly at launch.

Is it possible, in some way, to hide a device for a app that doesn't support explicit DRM device selection?

Brainiarc7 commented 1 year ago

No, not to my knowledge.

A while back, there was a request for this feature in libva but the RFC never went through. Let me check for that thread.

Ohh, this is unfortunate :(

Here it is intel/libva#221

I will close this issue in favor of that one.
