Fix in key frame detection
The frame next to scene cut frame does not usually have
a high second ref useage. Thus the sec ref useage of the
frame next to scene cut frame is tested against a
threshold for scene cut detection.
With this change scene cut detection is improved for
contents where genuine scene cuts were being missed.
