Detecting video playback error

edit

Hello all,

I am attempting to detect playback error, notably during transitions of videos being displayed. The types of error include:

• Video flickering (videos goes black, or goes white)
• Distortions, artifacts
• Unexpectedly blurry video (ie, 1920x1080 looks like 640x480)
• Huge FPS drops (lack of smooth transitions during playback)

Currently, I have applied edge detection and Hough transform to detect sharp changes from frame to frame with moderate success for the first two issues, but am not sure whether these solutions are optimal.

If there are better solutions out there, I'd love to try them! Thanks.
