I already found this link but the answer doesn't really say much about replacing more than one audio track. I quite don't understand the -map things he does in there and I would just like to replace 5 audio streams with 5 of my own.

I want to keep the meta data of the original file, I want to keep the naming of the streams and everything else but the actual audio stream. I know this has to be possible somehow with ffmpeg, I've been able to achieve what I wanted with Subler but I can't tell my users to download Subler every time they want to convert something which is why I want to find a fitting ffmpeg command.

Basically I want to keep the container "layout" and codecs but just edit the contents of it without modifying anything else

Ok what I've eventually done is removing all the audio tracks in Subler, adding that "almost empty" container to my application and used MP4Box' add command to fill in the audio again. No ffmpeg needed here
