[MPlayer-users] Histogram

[Dennis Perov]

Can I get a report from each frame's histogram?
I ant to split my videos into chapters and use histogram to detect
blank scenes and scene change + audio analysis to auto insert chapter
points. I know I can probably use pass1 log file to get the scene
changes, but a blank frame detection would really help too.
Can I see -pp=al 's  msglevel=9, I've tried '-msglevel
all=9:vfilter=9' but there was no PP report of any kind. I hope al
runs brightness/saturation analisys?

Thanks.
