I have a simple open source Go server for files, httpfolder. I would like to add the ability to stream MP4 files that have the moov box at the end, which confuses some browsers. I know that I could use something like MP4Box to do this.

However, would this package would allow me to do dynamically interleave the moov box without modifying the file on disk? The dynamic equivalent of "mp4box -inter 500 input.mp4"? Thanks for any pointers you can give me!
