#21 Editing container file directly to keep other information

[Alexander Nowak]

Hey I wanted to create a new thread in the forums for MP4Box but it somehow doesn't allow me to post anywhere but here, sorry for that.

I am trying to edit an MP4 container file but it also contains some non-mp4 info which I want to keep which is why I got across your MP4Box project. The file should stay exactly the same except that I want to swap audio streams in it. MP4Box looks like it would be able to do that but in your documentation it only tells you how to create something new instead of editing an existing file. I tried exporting stuff through FFmpeg before I came across your work and the problem with re-exporting is that all the "non-MP4" stuff gets rejected and doesn't make it into the target file.

Thanks a lot in advance
