I cannot explain the relevant specifications (and I
don't even know where to find them)

220 (8-bit) or 877 (10-bit) quantization levels with the black level
corresponding to level 16.00d and the peak white level
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)?

Hello Carl, no, I don´t.
Can you explain this to me?
I always thought that SD broadcast levels has to
be 16 and 235.
