QMediaPlayer not working on Windows 7 Pro x64
I'm experiencing a wierd issue with Qt Multimedia framework.
I'm trying to run the simple videoplayer example using Qt 5.5.1 under Windows 7 Pro x64.
As I select a regular mp4 video file, I have the following error :
Failed to set topology
I really don't understand where it comes from.
I haven't found any related information over the internet.
Actually, I don't even understand the meaning of this error...
Any suggestion is welcome.
NB: Note: before installing Qt 5.5, I have also installed video codecs with "K-lite Codec Pack"
It comes from the media foundation backend.
What do you mean by regular mp4 ? What are the streams format ?
