Enables a mode of sending differences between frames.
property FrameDifferenceInterval: Word
This mode works only if Encoding is rvet*Change.
Assigning a positive value to this property turns on a mode where only differences between frames is sent.
The value specified a number of video frames in a chain. For example, if FrameDifferenceInterval=5, a chain consists of 5 frames: the first frame is sent as it is, the subsequent 4 frames are sent as differences between the new and the old frame.
This settings reduces traffic, but:
•it requires more calculations on the sender side;
•if at least one frame is lost or corrupted (it is possible in UDP mode), drawing subsequent frames leads to artifacts appearing
