QtMultimedia examples crash
Unsolved
General and Desktop
-
Running the Media Player and the QML Media Player examples on an Ubuntu 20.04 machine, they crash whenever I open an .mp4 video file (tried different videos). The debug does not help because it just highlight a segmentation fault in some assembler code.
I have another machine with Ubuntu 20.04 and there I can open the very same video files with both C++ and QML Media Player examples.
I bet I'm missing some packages on the first machine... but how to find which?
By the way, I can play those videos using other applications, like vlc.Anyway, here the relevant packages I can think about:

What compiler on these 2 machines?
There were some issues when using some MinGW versions with Qt6 QtMM... Dunno if this got fixed
