Failure message:

TestError: Playback is not done correctly. The number of decoded frames (=4) is less than 100 for 30 seconds

So actually I'm not sure if this is related to power or not, however, only 4 frames are decoded in 30 seconds is definitely abnormal.

Some observations:

(1) video_PlaybackPerf are all green

(2) video_PowerConsumption of Grunt on R71 and R72 are also green
