#7061 new enhancement

Loudness histogram - like "showwavespic"-filter?

Description

Would it be possible to add a new filter, that can show the integrated loudness value of a file as a histogram in one picture? Similar to the filter "showwavespic" or "showspectrumpic".
It could look like the histogram here: http://f-video.s3.amazonaws.com/meters-large.jpg
This would really help my workflows for loudness as I could see on the scale where the loudness is bigger than it should. A graph with more than the integrated value would be cool, for example showing also the loudness range or short term or momentary values.
Thanks for considering my enhancement proposal - keep up the good work!

Whats wrong with ebur128 filter video output?

comment:2 Changed 4 months ago by BlackScreen

I want one picture, one single frame of the whole file - like with "showwavespic" or "showspectrumpic". With the ebur128 filter I only get a live output of the whole file, not an overview of the whole file.
If this would be possible with the ebur128 filter, then I would use this. But I have no idea how and would be very greatful for a tip. :)
