It just doesn't start at all. Tried removing and reinstalling with pacman -R. Or should I use stronger delete commands?
Solution: sudo pacman -Syu solved it. But why? What if I didn't have internet at the time and really needed these programs? It was something about qt GUI.
This:
mix incompatible Qt library (5.15.0) with this library (5.15.1)
Cancelled
Didn't post any logs/output from it, avidemux-qt and vlc launches fine for me.
Have you updated your system yet?
I only experienced a problem when it did not havewill to start from file manager but it started fine from terminal.
Whichever player I tried recently made me even more believe that mplayer is the best player out there.
When I run avidemux-qt, bash: no command found. When I run avidemux, same thing. But it's installed I can see it in applications.
I think there is something very wrong with your setup . Another programs works or same error?
put here output from
echo $PATH
