使用QMediaPlayer在WIndows上使用PyQt5的错误。

Attatched below is test script that I was using in order to play sample video for PyQt5. Unfortunately, soon after loading the video, the mediaPlayer mediaStatus switches to code 8 (InvalidMedia) I have also tried this with a local version of the .mp4, to no avail. I have tried other files, but am unable to diagnose the problem any further. I found this implementation of media player elsewhere on Stack Overflow, so if anyone knows a completely different way of implementing it, I am open to that.Attatched below is test script that I was using
