HEVC/x265 problem

[zShxck720]

Describe the bug While playing an HEVC (x265) file the video is laggy. I tried to change multimedia engine between MPlayer and MPV and nothing. Then I tried to change the output driver and nothing (some outiput drivers are worse than others), still laggy. But when I play it with the MPV app is perfectly fine.

Your Enviroment

• SMPlayer version: 23.6.0
• OS: Nobara (which is basically Fedora Linux)
• Multimedia engine you're using with SMPlayer (preferences -> general): [ x] MPlayer [ x] MPV Yes, both of them

Additional context Is there something I am missing?

Try enabling or disabling "hardware decoding" in preferences -> performance. You can also try to change the "threads for decoding".

Tried and nothing unfortunately.

Then i had an idea, I uninstalled the Flatpak version and installed SMPlayer from the .RPM version and now it works fine after setting performance --> Hardware decoding on AUTO.

The Only downside is the .RPM version doesn't have a Skinnable GUI so I can't put the Fusion skin on.

So basically the Flatpak version of this software seems to not apply changes on the hardware decoding
