trouble with intel hwacc vaapi

[derdigge1982 0]

Dear Community.

 

I am quiet new to emby. Until now i like it very much, it is clean and simple. On my archlinux box i am playing around with it. During that time i tried the hw acceleration of my i7-3770, which supports h264 accel through vaapi within ffmpeg. Running vaapi as root just works fine. Emby fails.

 

Hardware

 Intel i7 3770
 00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v2/3rd Gen Core processor Graphics Controller (rev 09)        Subsystem: ASUSTeK Computer Inc. P8 series motherboard
        Kernel driver in use: i915
        Kernel modules: i915

but permissions should be okay?

groups emby
emby video

Running that ffmpeg command as root seems to work just fine. I cannot play the result cause it splits in so many pieces.

any other permissions emby needs now? Any other thoughts?

lightning fast reply

 

Emby is allready in video group. see last code box. Was also my first guess.

[derdigge1982 0]

did it.

 

just removed emby user and recreated it with video as primary group for emby. Now it works. 

[Luke 38559]

Interesting. Thanks for the info !

[slevin7 62]

I know this is a really noob question but how do you remove emby user and recreated it with video as primary group for emby?
i have the same issue as you had and emy should be in the video group. i tried sudo usermod -a -G video emby. but still the same error

 

    Sorry, forget it. i forgot to restart the server. How embarrassing.

It shouldn't make any difference whether video is the primary or a secondary group.

 

Did you guys reload systemd and restart emby after making these changes? You need to do that as these changes don't take affect on an existing session.
