Detailed Description

This is an indication to the video encoder to change the way it is to encode the video stream.

The trade off integer is a value that trade spatial quality (blocky-ness) for temporal quality (frame rate). A value of zero will maximise spatial quality, sacrificing frame rate and a value of 31 will maximize frame rate and sacrifice
