Playing HTML5 video from local
===

I just learned [here][1] that in order to play some video in HTML5's `<video>` tag I should make sure that while serving video on some URL appropriate `Content-Type` has also to be set.

How can this be avoided when I simply run my web page from local file system or I don't have ability to manipulate server response headers?
