Help Wanted: Intel ARC testing

[feederbox826]

I have tested most other hardware accelerations, I am just missing Intel ARC. I have no reason to believe they should not work, but it would be nice to have validation :)

Thanks @nerethos for testing V4L2 ❤️

Sometimes works. Doesn't do anything for direct play, as expected. Arc not used for preview generation. GPU preview generation was a big ask on the main branch, and the thread is confusing if it's supposed to work or not, but it does not appear to work here, and I was never able to get it to work at all with the original project.

Errors with video freeze below. Video appears to continue to work when unpaused. Full disclosure, I had difficulty converting over from the main project, so this could be container corruption or something.

Thanks for the report! It does seem to be struggling with libva, will dive into that

I'm also seeing the above when using my i3-12100, but the transcodes are definitely working. The error seems to occur when ffmpeg has finished the transcode. FWIW I get the same thing with the testing branch on my docker image, which also uses jellyfin-ffmpeg6.

yeah, iirc iHD is the old <g8 driver, which means for some reason it's not using the qsv drivers. returns 0 means nothing went wrong, I think it could also be a pipe problem
