I can't read any video files with Qt. I have tried the Qt example and it still doesn't work. I have installed every packages needed to read video files with GStreamer.
In the QtCreator debug window, I have this message :
error : GStreamer encountered a general stream error
I have searched for a long time but haven't found any solution... Does anyone have one?
[EDIT] I could solve this problem using QGraphicVideoItem instead of QVideoWidget but now i have an other problem :
