A simple and effective way to achieve fast forward using the Locomote Video Player would be to modify timestamps before inserting them into the buffer. It can fairly easy be tested by adding the line
ts /= 2;

. This would play back the video twice the normal speed.
This is achieved by simply putting the timestamps closer together (above, each timestamp is divided by 2, hence that frame come in half the time it would at normal playback speed).
Some considerations:
