Throttling CTS producing frame speed

CTS checks the present time of the frame 6 frames ago. However, if
the default buffer count of BufferQueue is more than 7, CTS could
produce frames continuously in a short time. In this case, the frame
6 frames ago might be not presented yet then CTS fails. To prevent
this situation, CTS produces frames at the speed according to
compositeInterval.
