Check this article: http://www.fourcc.org/fccyvrgb.php Conversion is quite easy so you probably could write your own function based on this:
Y = (0.257 * R) + (0.504 * G) + (0.098 * B) + 16
Cr = V = (0.439 * R) - (0.368 * G) - (0.071 * B) + 128
Cb = U = -(0.148 * R) - (0.291 * G) + (0.439 * B) + 128
