[PyQt] I can't play MP4 files

[Axel_Erfurt]

I found it strange that someone recommends an avi converter in their first post. The question was actually about playing an mp4 file.
Or should it just be an advertisement for OmniConverter?

The code in at the start of the post did include this:

        filename, _ = QFileDialog.getOpenFileName(self, "Open Video",
                                os.getcwd(),
                                ("Video Files (*.avi  *.mp4)"))

That must have been a very old program that that rwahdan found online.
