When I connect The server core dumps:

Your GPU does not support HEVC encode, which is the default.

See in https://github.com/Meumeu/WiVRn/blob/master/docs/configuration.md#encoders how to configure for h264. However, don't expect reasonable performance with such a GPU.

Oh bummer, Im not going to play games, just wanted to maybe have a xterm or something,,

I tried with h264 as well, but get the same error and crash:

You have to change the codec, not encoder:

{
    "bitrate": 50000000,
    "encoders": [
        {
            "encoder": "vaapi",
            "codec": "h264"
        }
    ]
}

Thank you for your help! Now I am getting a different crash:

UHD Graphics 630 is supposed to have hevc encode, and support the required features (constant bitrate for latest error).

Your vaapi setup may be incomplete.

I do not plan to add support for hardware that doesn't have CBR.

[makenb]

You were right I am running ubuntu and I needed to install some more packages:

intel-opencl-icd intel-media-va-driver intel-media-va-driver-non-free

Maybe some others... Now it is running vaapi h265! I was able to run xrgears to check.

Thank You
