I unfortunately canā€™t help you here with anything Windows.
I did hear that Windows HW decoding had a problem but donā€™t know any details of it.

I suggest looking in the Windows Desktop player section.

Am I understanding correctly that your Nvidia P4000 is working on Fedora?
Which Nvidia driver version and which kernel version are you using?

I ask because Iā€™ve found my rtx 2000 runs best on the Ubuntu-vetted 565.77 drivers (570 is not yet public/production stable). Iā€™m running 6.8.0-52 kernel

Was this updated or is this still under way? Because on my Fedora 41 installation with a Pentium 4415Y (HD 615 GPU), I still canā€™t get hardware acceleration working.

That fix hw decoding on my t490. Thanks!

I am also interested in this line of code for the LIBVA drivers, but in a different way. I installed mpv from a snap package, which appears to use the correct driver files when playing a local video file. Intel_gpu_top reports the video hardware is in use, and CPU usage is low.

Since the plex flatpak points to something involving snap, would there be a way to point it to the LIBVA drivers that come from the mpv package installed?
I donā€™t understand how to read the line to access the structure of files in a snap, or how I should change it to point elsewhere to look for the libva drivers. Is there an easy to understand explanation of the syntax?
