Memory leak from QMediaPlayer

Attached script continuously loads media files with QMediaPlayer.setSource(). Just put some mp4-files into _VIDEO_DIR path defined in string #8.

On my system I put only 2 mp4-files in it. Leak rate is almost constant and is about 12 MiB in 5 minutes:

On start: 195 MiB physical memory

10 min: 219 MiB

15 min: 228 MiB

20 min: 240 MiB

25 min: 252 MiB

30 min: 264 MiB

And so on...

Tested with Python 3.12.3 on Kubuntu and Xubuntu 24.04.01.
