Transcoding with Intel Arc A750 Not Working

[jos64]

Hi, I didn't say that it had anything to do with jellyfin or jellyfin-ffmpeg.  I think it is a driver issue or Linux kernel issue, but looking for advice or others who may have the same problem.

As for @Re4mstr, I doubt that this is caused by a Jellyfin regression.

For me, I have read that documentation front-to-back tens of times already.

Here is the output for checking the supported QSV/VA-API codecs:

Code:

vainfo --display drm --device /dev/dri/renderD129

Code:

      VAProfileVP9Profile3            : VAEntrypointEncSliceLP
      VAProfileAV1Profile0            : VAEntrypointEncSliceLP

And when checking the OpenCL Runtime status (which freezes ffmpeg just like when Jellyfin tries to transcode a file):

Code:

/opt/jellyfin/ffmpeg/ffmpeg -v verbose -init_hw_device vaapi=va:/dev/dri/renderD129 -init_hw_device opencl@va

Code:
