...UV420 2x2 upsampling.I haven't studied the impact of this processing on the codec, but I believe that better downsampling and upsampling algorithms for U and V components will bring better quality to the codec.Here is the upsampling I'm thinking of, the demo page is very impressive: https://kdepepo.wordpress.com/2012/08/15/reverse-antialiasing-for-image-scaling/ . I have also (yet) another idea for the quantization/compression scheme to gain compression and create good lower quality settings.I will try to code and test it this month. To finish, I maybe get used to notice neatness/sharpness...
