How to play MP4 (H.264 video) in Silverlight 3 (or 4) from a URL?

问题

So I have some URL of an MP4 file. I want to develop a simple Silverlight application to play it.

How to do it? (Preferably with example code.)

Ole Jak,

Here is a suggested step-by-step:

Step 1: Create a sample Silverlight application with Visual Studio (File / New Project / Silverlight Application

Step 2: In your newly create project, edit the MainPage.xaml, and place the following code inside the UserControl's Grid

<MediaElement Stretch="Uniform" Grid.Row="0" Width="400" Height="300"
     AutoPlay="true"
     Name="x_Media"
     Source="http://silverlightatlanta.net/Firestarter/Videos/TimHeuer_2.mp4" />

Step 3: Build and Run!

The mp4 file you trying to play does not contains moov header. That way, the player need the complete file to start playing. I recomend that you run mp4box on the file to include moov headers.
