Hi. We have an app we've been deploying for years now, last version on Qt 5.15.x, our QMediaPlayer modal was working fine.
Recently, we started the port process to Qt 6, 99% done and working, but now the video stutters bad. I thought maybe I had more code work to do in our video player for Qt 6, but then I opened up the Qt 6.2.4 (what we're on now) example media player and ran that with the same video as well as some vids downloaded from the net, Qt's own example player video stutters too!
I also tried using Qt 6.4, still stutters, is video playback broken in all of Qt 6? Thanks.
I spent 4 hours searching for the issue, I can't find anything on it which is surprising to me. Oh and I tried on 2 different machines, both Windows 10 64b.

The 2 machines I was messing with were actually VM's in Parallels. I tried a real WIndows 10 machine and no issues. However, I can run our 5.15.X version in the VM's and media playback is fine, so something is still off with Qt 6 Media.
