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)? Sorry if I misunderstand (and my knowledge about the question is definitely limited) but do you realise that valid (specification-compliant) broadcast-range video may contain values < 16 and > 235?

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. Best Regards Christoph
