      Description

      The app crashes with QML MediaPlayer.play() when
      main.cpp

          QCoreApplication::setAttribute (Qt::AA_UseOpenGLES);
      

      main.qml

              MediaPlayer {
               id:player
               ...
               source: Qt.resolvedUrl("sample.mp4") 
               ...
              }
      
              VideoOutput {
                  id: vo
                  opacity: 0
                  source: player
                  flushMode: VideoOutput.LastFrame
                  onContentRectChanged: {
                      vo.opacity = 1
                  }
              }
      

      When it crashes/hangs, the dialog appears

      Sample code is attached qtbug102316-QtQMLVideoSample.zip. Please run and click the window to execute play().
      This works fine with Qt5.15.6 or 5.15.7.
