title: The best way to use Video with QGraphicsScene
body: <p>I am currently using Phonon VideoWidgets inside of a QGraphicsScene using a QGraphicsProxyWidget.</p>
  
  <p>I have my viewport set to a QGLWidget.</p>
  
  <p>However, it causes me big issues when I try to apply some transforms to the video such as a rotation that isn't evenly divisible by 90 degrees since then it slows my program down a lot.</p>
  
  <p>After reading the few things I managed to find on the subject I found that it seems that when using a VideoWidget inside a QGraphicsProxyWidget it will do software transforms which would explain the massive slowdown.</p>
  
  <p>So I was wondering if there is a better way to render the video.</p>
