== Interframe delay stat for video receive stream. ==
This could be a useful metric to detect freezes in video, detect lost frames or network problems.

Definition: It is a difference between time moments when two consecutive received frames are decoded.
For the first frame it should be set to 0.

As according to guidelines, it should be reported as a sum of interframe delays for all received frames. Reported value is actually a delay between the time of decode of the last received frame and the time of decode of the first received frame.

Then average interframe delay may be calculated by dividing the reported value by the number of received frames minus one.
