Is the url valid? Try to open it directly in Chrome for example. As an alternative, you can try other sources, like:
http://techslides.com/demos/sample-videos/small.mp4[

Be aware, that there can be a problem, if the server is trying to deliver the video file as attachment or with inproper mime type. For IIS you can add it to the
web.config
(or
in several other ways[
^]), like this:
<staticContent>
<remove fileExtension=".mp4" />
<mimeMap fileExtension=".mp4" mimeType="video/mp4" />
<remove fileExtension=".webm" />
<mimeMap fileExtension=".webm" mimeType="video/webm" />
</staticContent>
And I recommend using this player to have a cross-browser solution:
