Strange problem with FFMPEG's stdout

[Piero]

I don't think ffmpeg has audio normalization(removing loudness difference between audio tracks).

https://ffmpeg.org/ffmpeg-filters.html#loudnorm

https://ffmpeg.org/ffmpeg-filters.html#dynaudnorm
Just an example:

Code: Select all

 -af 'dynaudnorm=g=3:c=1:m=10:f=10:b=1' 

I also hope you saw https://www.shutterencoder.com/ ; free and has useful functions you don't easily find elsewhere (also has audio normalization)

That's good that completes everything you need for good transcoding and encoding. I think they even support Dolby and DTS encoding, but not TrueHD, but I've always went with aac stereo.
