    Description

      Video: https://gitlab.com/kelteseth/ScreenPlay/-/blob/master/Content/wallpaper_video_nebula/mantissa.xyz_loop_072.mp4

      This is with the ffmpeg backend on Windows 11 with latest AMD driver (Vega VII). Does not crash with windows backend!

      qputenv("QT_MEDIA_BACKEND", "windows"); 

      this is with ffmpeg release and debug:

      Steps to reproduce:

      1. You need Windows with an AMD card
      2. Download LoooopyLoop.zip attached test project
      3. Download test mp4 https://gitlab.com/kelteseth/ScreenPlay/-/blob/master/Content/wallpaper_video_nebula/mantissa.xyz_loop_072.mp4
      4. Select the file and press play
      5.  Change  qputenv("QT_MEDIA_BACKEND", "ffmpeg"); in the main to 
        windows. This will not crash, ffmpeg does.
