title: How to find video resolution and aspect ratio of QMediaPlayer video?
body: <p>This seems too simple, I must be overlooking something?</p>
  
  <p>How do I find the native video size or aspect ratio from a video file being displayed by a <code>QMediaPlayer</code>?</p>
  
  <p>The video Resolution, PixelAspectRatio, etc., should be in the MetaData, but I wait for MetaData Update Signals, and wait for seconds after the video <code>.play()</code>s, but <code>isMetaDataAvailable()</code> always returns false, and <code>.availableMetaData()</code> and <code>.metaData(QMediaMetaData::Resolution).toSize()</code> always return empty.</p>
  
  <p>There seems to be nowhere else to get the video resolution information, or am I missing something?</p>
  
  <p>I can open the video, play the video at full screen, etc.</p>
