Jellyfin freeze on M1 Mac mini

[sevenrats]

I don't know all the details, but its not terribly surprising that this doesn't work. Jellyfin needs to be built for this architecture directly, and, I suspect running the x86 ffmpeg through the Rosetta layer is causing this issue, and this is sorta corroborated by the fact that your log ends during a transcode.  If you have a bit of grit, my next step would be to try using Vargol's native builds of ffmpeg, and swapping out the x86 ffmpeg binary with a native built one. https://github.com/Vargol/ffmpeg-apple-arm64-build
