[FFmpeg-user] Display rgb statistics

[Robert Krüger]

Hi,

what is the recommended way to display stats about the pixel values of rgb
files? The signalstats filter seems to only support yuv, at least the
documentation does not mention anything about R(GB)MAX/AVG and the filter
does not output anything either when specifying those.

I am asking this to make a bug report that does not require anything but
ffmpeg command line tools.

Thanks in advance,

Robert
