Media Player Fails to load (error 0xc0000142)

[KodiUser1138]

This just started happening. I upgraded to 10.10.7 the other day and tried using Jellyfin Media Player and suddenly getting this error. Didn't see a prior thread or solution specific to media player and uncertain what is happening. Seems odd it was working fine before but it's been a little bit and was on prior server version.

Is all your artwork blurred too like mine is?
Im running Jellyfin on a Umbrel and literally just updated it within the last few hours and it stopped being able to load artwork or play videos

Are you using a reverse proxy? If so, you would need to add your proxy's IP to the known proxies field in Dashboard > Networking.

The media player doesn't even start so I don't get far enough to be able to tell. Sorry that doesn't help you.

I am and I had this working a week ago (before the 10.10.7 update) and now the media player just doesn't start. It's not, at this poitn, a server connection issues it's an application execution issue. Immediate failure.

Appears to be an issue with the Media Player 1.12.0 Windows x64 version. I removed it and re-installed 1-11-0 and that works fine.

This happens when you have an older CPU that doesn't support one of the following instructions:

Code:

avx avx2 bmi bmi2 fma lzcnt movbe sse3 sse4 sse4.1 sse4.2 ssse3 xsave sahf mwait crc32 cx16 popcnt f16c

You need to use the legacy build: https://github.com/jellyfin/jellyfin-med...legacy.exe

For the record, it isn't just older CPUs. Newer, but low power, Intel CPUs also do not support AVX. Looks like E-core/Atom class CPUs PRIOR to Alderlake-N do not support AVX or AVX2.

Thanks for the tips. Reverted back to 1.11.0 so that works for now. Will test this legacy version.
