回答1:
Add the mime type to the server or web application web.config, (or in IIS under mime types).
<system.webServer>
<staticContent>
<mimeMap fileExtension=".mp4" mimeType="video/mp4" />
</staticContent>

it's a quite a simple answer: Windows server 2008 has no mpeg-4 multiplexer, so you cant see any mp4 on your machine with default configuration of your server.
you can notice that if you stand with your mouse cursor on a video file in your computer you will able to see basic file info like name and duration.
at your server you might find out that if you do the same on an mp4 media file you will not able to see this information...
the answer for that issue is to go to server manager under the administrative tools in your windows server 2008 r2 from the start menu.
from there you need to choose features in the left side. after that you need to prees add features and select DESKTOP EXPERIENCE and install.
this is the primary thing you need do do for you machine to be able to read mp4 info. after that you need to mime type for your mp4 media files. install codecs.
