[FFmpeg-user] Numerical histogram output for checking typical broadcast ranges (16-235)

[Christoph Gerstbauer]

Hello,

I am very new in using the histogram filter.
(http://ffmpeg.org/ffmpeg-filters.html#histogram)

Is it possible to dump the video level values from which the histogram
graph is drawn into numeric values (textfile dump) to check if a video
has levels inside the broadcast ranges (16-235/94-940)?
