PHP to Python: Moovrelocator

I've found library in php called moovrelocator. Description from it's site: MOOV Relocator is a well documented small library written in PHP to relocate (开发者_如何学Cor move) the MOOV-Atom of MP4-Files from the end to the beginning of a file.

And it works pretty well with php.

Unfortunally I haven't found such library in python. And I want to ask community. Is there any library with which I can replace php-moovrelocator?
