When I open a video in VLC, the video doesn’t start.

The log says:

What type of file is it? MPEG, AVI, MP4…?

Maybe you also want to check VLC configuration in Tools → Preferences → Video tab. Then find Output. Change from Automatic to other than YUV. If you’re using Nvidia driver most likely you can select VDPAU output or you can trial and error with other list available there.

It’s MKV. It’s the first row of the mediainfo output I posted :slight_smile:

I tried changing the video output but it doesn’t fix it.

I don’t have NVIDIA drivers right now, I uninstalled it to try to fix this but it’s not due to NVIDIA drivers apparently.

I just tried and it works again…

Sometimes “reboot” is a good suggestion actually (I guess).

Btw there also local conf inside user home dir. ~/.config/vlc and ~/.local/share/vlc. May be if there any problem come again, we can try to reset the configs by deleting both directories.
