MediaPlayer on windows /RaspberryPi

[The Qt Mayssa]

Hello,
I'm using qt creator to display some widgets with a c++ program for example video in this case but i have some problems:

• poor quality on rapsberryPi 4 -> did you face this problem ? how did you fix it ?
• api used on unix and windows not the same: for example gstreamer on unix(raspian) and directshow on windows (https://doc.qt.io/qt-5/qtmultimedia-windows.html)
  ps: i need to make my program work on both environments and for sure have a close behaviour .
  so i have 3 options and i dont know what to go for :
• create a VlcItem that uses vlc lib in c++ ( not my favourite)
• compile gstreamer on windows to firce it work with gst
• use different Api's , there is not a huge different between them.
