[FFmpeg-user] Extracting video levels on the command line

[Robert Krüger]

Hi,

is there an easy way to extract things like min/max of each video component
for a video using the command line? I first thought, there may be a vstats
filter that more or less does what astats does for audio but that does not
seem to be the case.

Is there any other way than looking at each frame's histogram (using the
histogram filter) and counting pixels?
