NOTE:
Embedded sync input source is already clipped because the two 0x00 and 0xFF codes are
illegal values in the active video data and they are reserved only for start codes.
If there is any need to down the line to pack this stream into an embedded sync format (input
source contains the 0x00 and 0xFF codes), then the VIP Parser can be configured to clip the
data on the way to being stored in memory. This prevents MPU or DSP to go through every
byte to check if the data has to be clipped.
