Is there a way to report RGB statistics per frame with FFmpeg?

admin

so far the signalstats only report YUV, and it always convert rgb to yuv first.
here I force r,g to be 0, only give some b pixel slightly above 0
ffmpeg -i input.mp4 -vf "format=rgb24,geq=r=0:g=0:b='if(gte(b(X,Y),200),1,0)',signalstats,metadata=print:file=logfile.txt" -f null -
