I don't wanna waste my time on this pointless argument no more
Code:
colorbars (pixel_type="rgb32")
ycgco = dither_convert_rgb_to_yuv (output="yv24",lsb=true,matrix="ycgco",tv_range=false)
ycbcr = dither_convert_rgb_to_yuv (output="yv24",lsb=true,matrix="601",tv_range=false)
rgb48ycgco = dither_convert_yuv_to_rgb (ycgco, output="rgb48y",matrix="ycgco",tv_range=false,lsb_in=true)
rgb48ycbcr = dither_convert_yuv_to_rgb (ycbcr, output="rgb48y",matrix="601",tv_range=false,lsb_in=true)
rgb48cgco = mergergb (rgb48ycgco.selectevery (3,0), rgb48ycgco.selectevery (3,1), rgb48ycgco.selectevery (3,2)).subtitle ("ycgco")
rgb48cbcr = mergergb (rgb48ycbcr.selectevery (3,0), rgb48ycbcr.selectevery (3,1), rgb48ycbcr.selectevery (3,2)).subtitle ("ycbcr")
StackHorizontal(rgb48cgco,rgb48cbcr)
just stare at the LSB part of "ycgco" and "ycbcr" real carefully and tell me what's the difference, which one is "lossless"
