using MediaElement play video issue

Question

Hello everyone,

I am using the popular sl2videoplayer from codeplex to play video, and everything is fine when I play remote video on an IIS web server. Sl2videoplayer could be found here, http://www.codeplex.com/sl2videoplayer

But when I open the default.html locally from disk (double click default.html to open in IE), there is error message in IE like this (there is a warning sign in IE at the left bottom corner, please refers to the below screen snapshot). There is no code change in sl2videoplayer except that I change the media file to Output.wmv as shown below. Any ideas what is wrong? The effect I want to achieve is I want to play local file using the silverlight player without connecting to server (when disconnected from internet), could we do that using Siverlight.

default.html I am using (I copied Output.wmv into ClientBin directory, and VideoPlayer.xap resides in the same directory)

    <div id="silverlightControlHost">
  <object data="data:application/x-silverlight," type="application/x-silverlight-2" width="500" height="240">
   <param name="source" value="ClientBin/VideoPlayer.xap"/>
   <param name="onerror" value="onSilverlightError" />
   <param name="background" value="white" />
   <param name="initParams" value="cc=true,markers=true,markerpath=markers_movie21.xml,m=Output.wmv" />
   <a href="http://go.microsoft.com/fwlink/?LinkID=115261" style="text-decoration: none;">
        <img src="http://go.microsoft.com/fwlink/?LinkId=108181" alt="Get Microsoft Silverlight" style="border-style: none"/>
   </a>
  </object>
  <iframe style='visibility:hidden;height:0;width:0;border:0px'></iframe>
    </div>

It seems to me that it's complaining that one of the paths provided is not a fully valid URI. A relative one should be fine, though.

I'm not sure what line 53 is, but it is complaining that the problem is present at character 13 in that line. Do you have the markers_movie21.xml you refer to with the "markerpath" attribute? That might be part of your problem - try removing the attribute if you don't have the file and see if that works.
