play media file error in Silverlight

Question

Hello everyone,

I am using Silverlight 2 + VSTS 2008 + C#. And I downloaded source code from the popular sl2videoplayer, http://sl2videoplayer.codeplex.com/ then I build the solution and then using IE to open default.html. But no video is played, here is the error message from IE and screen snapshot from IE. Any ideas what is wrong and analyze further?

Answer 1

Try putting the app directory on a web server and accessing it on the server. Local file playback doesn't always work that well.

Answer 2

George2 - I'm assuming the media parameter for the video player you are using is http? if so, you are running your html page under the file:// scheme. You must use the same scheme for web requests in silverlight. Run the page under a web context (cassini in VS or IIS or whatever) and ensure the scheme matches the URI scheme for the media file. Avi's answer is correct, I'm just providing more context as to why you are getting this error possibly.
