1511 * Write out 2 RGB pixels in the target pixel format. This function takes a
1512 * R/G/B LUT as generated by ff_yuv2rgb_c_init_tables(), which takes care of
1513 * things like endianness conversion and shifting. The caller takes care of
1514 * setting the correct offset in these tables from the chroma (U/V) values.
1515 * This function then uses the luminance (Y1/Y2) values to write out the
1516 * correct RGB values into the destination buffer.
