VLC problem

[sjsj]

Hello,

Sorry, I speak a little English.

If I click the VLC icon in left panel in Debian 10, not show the application window and if I try play the movie file (.avi) not see the application window. I can run only the terminal in vlc command in Debian 10. If I restart the PC the problem is solved, but only sometimes, not always.

Sounds like a video problem in GNOME. Have you tried starting GNOME in xorg mode, or installing a small, different DE like XFCE alongside GNOME, to see how VLC works there?

You can also try starting vlc with the suggested "QT_QPA_PLATFORM=wayland" to see if that helps. I think that a websearch will show you how to add it to the vlc command, since I don't remember exactly.

QT_QPA_PLATFORM=wayland

I'm sorry, but I had no time try this and I would not like XFCE or other. Not just a problem for me. Please see: forum.videolan.org

Sorry, but no one here gets paid for their time helping others either. It's a shame that you couldn't take literally just a couple minutes to install and try XFCE to narrow it down to a GNOME issue.

what does

A VLC futtatása az alapértelmezett felülettel. A VLC felület nélküli használatához használja a „cvlc” parancsot.

mean?

From google translate (hungarian to english):

Code: Select all

Run VLC with the default interface. To use the VLC without the interface, use the "cvlc" command

There's another error:

Code: Select all

Failed to open VDPAU backend libvdpau_nvidia.so: Cannot open shared object file: No such file or directory

is this a snap install of VLC player?
