DESCRIPTION
The mlib_VideoColorJFIFYCC2RGB420() function performs color
space conversion from YCbCr to RGB together with samplingrate conversion when used in the JPEG File Interchange For-
mat (JFIF).PARAMETERS
The function takes the following arguments:rgb0 Pointer to upper destination RGB multi-component
row. rgb0 must be 8-byte aligned.
rgb1 Pointer to lower destination RGB multi-component
row. rgb1 must be 8-byte aligned.
y0 Pointer to upper destination Y component row. y0must be 8-byte aligned.
y1 Pointer to lower destination Y component row. y1must be 8-byte aligned.
cb0 Pointer to source upper Cb component row. cb0 mustbe 8-byte aligned.
cr0 Pointer to source upper Cr component row. cr0 mustbe 8-byte aligned.
cb1 Pointer to source middle Cb component row. cb1 mustbe 8-byte aligned.

cr1 Pointer to source middle Cr component row. cr1 mustbe 8-byte aligned.
cb2 Pointer to source lower Cb component row. cb2 mustbe 8-byte aligned.
cr2 Pointer to source lower Cr component row. cr2 mustbe 8-byte aligned.
n Length of Y component row. n must be even. The length of Cb and Cr component rows must be n/2. Thelength of the RGB multi-component row must be 3*n.
RETURN VALUES
