Thanks natt, I have wondered why RGB<->YV24 conversions were not lossless color wise using chromaresample=point - now I know why.
However, I'm not sure though and can't test it now but if memory serves me right there also was something fishy going on if doing an (interlaced) YV12<->YUY2/YV16 conversion using pointresize, meaning converting back and forth is not lossless as one would expect.
