There is a project which compiled ffmpeg to javascript to allow videos be manipulated and converted in the browser:

It was originally developed as part of a Node Hackathon, but its not clear whether it is still maintained (see the GitHub activity).

Its worth nothing that it is probably more of an experimental project that a practical one, because of the very large file size.

First ask yourself "is it realy needed to selfhost my video?" Video plattforms like youtube or vimeo are faster and would bring this options with them.

  • The videos aren't on my server but they are on a website and i take the link to mp4 file so they hasn't got an user interface. –  Feb 07 '16 at 11:03
