The mlib_VideoColorBGR2JFIFYCC422() function performs color space conversion from BGR to YCbCr together with sampling rate conversion when used in the JPEG File Interchange Format (JFIF).
The function takes the following arguments:
Pointer to destination Y component row. y must be 8-byte aligned.
Pointer to destination Cb component row. cb must be 8-byte aligned.
Pointer to destination Cr component row. cr must be 8-byte aligned.
Pointer to source BGR multi-component row. bgr must be 8-byte aligned.
Length of Y component row. n must be even. The length of Cb and Cr component rows must be n/2. The length of the BGR multi-component row must be 3*n.
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
