The mlib_VideoColorJFIFYCC2RGB420() function performs color space conversion from YCbCr to RGB together with sampling rate conversion when used in the JPEG File Interchange Format (JFIF).
The function takes the following arguments:
Pointer to upper destination RGB multi-component row. rgb0 must be 8-byte aligned.
Pointer to lower destination RGB multi-component row. rgb1 must be 8-byte aligned.
Pointer to upper destination Y component row. y0 must be 8-byte aligned.
Pointer to lower destination Y component row. y1 must be 8-byte aligned.
Pointer to source upper Cb component row. cb0 must be 8-byte aligned.
Pointer to source upper Cr component row. cr0 must be 8-byte aligned.
Pointer to source middle Cb component row. cb1 must be 8-byte aligned.
Pointer to source middle Cr component row. cr1 must be 8-byte aligned.
Pointer to source lower Cb component row. cb2 must be 8-byte aligned.
Pointer to source lower Cr component row. cr2 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 RGB multi-component row must be 3*n.
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
