Subject: [Midplayer-private-dev] [helix-client-dev] CR: Add black framedetection in thumbnail,so we can get valid frame(non-blank) form the video stream as thethumbnail.

 

Synopsis: 

  Add black frame detection support in thumbnail, so we can get valid frame (non-blank) form the video stream as the thumbnail.

 

Overview: 

   Currently, we always get first key frame of a stream as the thumbnail, and many of these frames are black, so we can’t get the needed information. Then we add black frame detection, until we get a valid frame then stop doing thumbnail.
