Working config for libva-nvidia-driver and Kodi

Hey,

I have the weirdest problem and it's doing my head in.

The only way to get HEVC hardware decoding in Kodi (I've found so far) is to use libva-nvidia-driver, and set some env vars.

It works great after a reboot, for about 40-50 minutes then screws up big time. Videos just don't play properly and have massive pauses on the display.

I run a TV box PC with a 1660Ti and don't care about hibernation, suspend, any of that.

Things I've tried to fix it:
- Various env vars
- Nvidia module options
- nvidia-settings settings
- KDE settings (X11)
- GNOME does the same thing (again, X11)
- GDM power settings
- Masked out any systemd Nvidia service to do with hibernation etc

I'm at a complete loss as to why it works great for a while, then massively screws up. Restarting X, even logging into a different DE, makes no difference. The only thing that resets it and makes it good again is a reboot, but only for a while.

Setting Kodi back to only using software decoding works right away.

Any tips appreciated.

P.S. I also thought Pipewire might be the culprit, based on sync messages in the Kodi log, but doesn't seem to be.

P.P.S. Just failed again, 55 minutes uptime.

Once it starts happening...

warning <general>: OutputPicture - timeout waiting for buffer
