The problems I'm seeing don't seem like just problems of light and dark gray winding up white and black. I'm having white map to pale green. I suppose this could result from quantization/clipping somehow, since R, G, and B do not have equal weight. I'll have to do some histogramming to see if this is the case.
I tried passing a static, noiseless yuv stream (made from a single image) through yuvdenoise - no visible changes (as one would hope). That, and the fact that yuvmedianfilter shows the same color shift, suggests that something about noise reduction in general or as applied to YUV values is to blame. It may be that filtering should be performed in RGB, or that the noise is mostly red and blue and the filter needs to adaptively equalize the color balance. I may look into it further. Since I know a lot of people use yuvdenoise, I would like to hear if they see color shifts in the output?
