Here are some comments and flames: I noticed that when I set min to a value greater than max. I get a crash with "Bus error: 10". There may be an issue with negative values for min/max. When I run: ffplay -f lavfi -i color=gray -vf signalstats,drawgraph=lavfi.signalstats.YAVG:min=0:max=255 I see a line scroll across the center of the window. When I change min to -255 I see a line at ~3/4 down the frame, where I would expect -128 to be. Does the min and max expect non-negative numbers. It could be helpful to include equations within foreground, such as: ffplay -i movie.mkv -vf "signalstats,drawgraph=lavfi.signalstats.YAVG:min=0:max=255:foreground=if(gt(lavfi.signalstats.YAVG\,128)\,green\,red)" or actually I could probably subsequently use geq to accomplish that. Can you alias 's' for 'size' as many of the other filters do. This is very helpful, thanks!
