I know my setup with intel integrated gpu worked prior to the release pf 10.9. Now I can’t get transcoding to work. In the comments they suggest the kernel version has something to do with it but for me it didn’t fix it. I’ll have to troubleshoot further today

Meanwhile transcoding works fine in Plex, so I feel it may be something specific to jellyfin
