I noticed that HW transcoding suddenly stopped working. It worked before.  
Any idea on it? I read a ton of articles and tried to fix but no luck.

Me too.  
I used it normally before, and the hardware transcoding failed after the upgrade. I tried the package version and docker version, Exactly the same.Brother, have you solved it?

Try to use version 1.32.1.6999  
I used this version to successfully enable hardware acceleration again!

Yes… it started working again… Thanks for your suggestion.  
I think there might be an issue with 1.32.2.XXX. Hopefully, Plex team could fix it.
