Debug Log: https://pastebin.com/F6ACAL3W

Issue is that since updating from 18.9 to 19.1 I am having stuttering playback on 1080p content, and cpu sits on 100% throughout video playback.

I'm using Arch x86_64, on old hardware but its been running great for years. Kodi 18.9 played smooth video with very low CPU usage.
CPU is AMD 4850e (old, I know)
GPU is NVidia GT1030, vdpau installed along with proprietary driver.
libvdpau 1.4-1
nvidia-dkms 465.31-1

kernel versions: 5.12.11 and 5.10.44-lts

Kodi version is default Arch compiled package, kodi-x11 19.1-1 and kodi-common 19.1-1
I even deleted the entire database, reimported all media, deleted $HOME/.kodi folder and reinstalled kodi, but sme issue remain.

I can play the same video with VLC and MPV and it correctly uses hardware acceleration, cpu usage remains about 5-10% throughout. However there is no hardware acceleration options in Kodi GUI for me.

$ vdpauinfo
command reports that everything appears normal but can post to a pastebin if needed.

I'm afraid you're gonna have to yell at the Arch Linux developer people, as they do their own finetuning, compiling, packaging and releasing of Kodi.
We currently only support Ubuntu Linux ourselves via our PPA.

OK, thanks. I'll post there.
