VAAPI without X server

Hi! I have a VM in a ESXi server that is a headless Arch machine. The server has a i5 8400, so I made a direct passthrought of the iGPU to the VM. I also disabled the ESXi default graphics device, so the only graphics card is the passthought one. I want to to use iGPU to transcode with ffmpeg using quicksync, so the first thing to do is getting VVAPI to work. As it's a headless machine, the Arch instalation doesn't have X server installed, so when I run "vainfo", I get the following error.

# vainfo
error: XDG_RUNTIME_DIR not set in the environment.
error: can't connect to X server!
vainfo: VA-API version: 1.8 (libva 2.7.1)
vainfo: Driver version: Intel iHD driver for Intel(R) Gen Graphics - 20.1.1 ()
vainfo: Supported profile and entrypoints
...

The ffmpeg error is the following, but I guess I have to solve vainfo error first:

[AVHWDeviceContext @ 0x55dbf37692c0] Error initializing an MFX session: -3.
Device creation failed: -1313558101.
Failed to set value 'qsv=hw' for option 'init_hw_device': Unknown error occurred
Error parsing global options: Unknown error occurred

Do you know how to solve this? (Or if it is possible)

Re: VAAPI without X server

mpv can do VAAPI without X (use --gpu-context=drm), so it's possible. vainfo can do it too, you need to use --display drm --device <device>. But I have no experience with ffmpeg, so can't help you there.

Re: VAAPI without X server

https://gist.github.com/Brainiarc7/95c9 … 1bed379219 looks like it should be helpful for configuring ffmpeg + vaapi

As it's a headless machine, the Arch instalation doesn't have X server installed

X can be installed on headless machines if desired but does need some aditional configuration.

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
