n+1 is mapped to frame buffer 1, frame n+2 is mapped to Frame buffer 2, further frames wrap. A
codec request occurs, and the full-size 4:2:2 encoded frame is stored in a dedicated memory
space.
Depending on user selection, this module can be bypassed so that input YCrCb stream is
directly connected to the format converter module. If the RGB input stream is selected, this mod-
ule converts RGB to YCrCb color space with the formulas given below:
