I am trying to change volume in the specific way in AAC file. So far as I know "volume" filter allows to change volume on the whole AAC file. What I need is to change volume only on part of file. To be specific, let say I have AAC file which is one minute long: 1. I want to set volume 0.5 in the file starting from time 5s till 15s. 2. Then I need set volume 0.8 starting from time 35s till 50s.
Is it possible to implement it in the code with FFMPEG "Volume" filter? Is it possible to execute points 1 and 2 at one go?
