Strange. First you steer me in the direction of volumedetect and now it seems the other way around.
I will explain one last time: using the intermediate value of r128.I or its equivalent from volumedetect for volume normalization is WRONG. I do not want to help doing something wrong, nor will I support adding a feature in ffmpeg whose main use is to do something wrong. I also believe that it would have been better if Clément did not expose the intermediate value of r128.I, only its final value.
The RIGHT way of doing normalization is to use either a smoothed immediate value or the final value with two passes. The first pass would cost almost nothing if correctly implemented.
So am I correct that there is no smoothed intermediate value available as of today? One liners are just sexy if it were possible to do volume normalization on the fly :) -roger-
