I have a media element for which I wish to dynamically set the source. I'm able to do this for local video, but not for a streaming source. the following scenarios illustrate my problem:

Hard-coded embeded video source. This works:

<MediaElement  AutoPlay="false" Name="mediaBox"  Source="localVid.wmv"  />

Hard-coded streamed video source. This works:

<MediaElement  AutoPlay="false" Name="mediaBox"  Source="http://play.rbn.com/play.asx?url=cspan/cspan/wmlive/cspan1v.asf"  />

Dynamically assigned embeded video source. This works:

<MediaElement  AutoPlay="false" Name="mediaBox"  Source=""  />
in javascript file: sender.findName("mediaBox").setSource(sender,"localVid.wmv");

Dynamically assigned streamed video source. This throws an AG_Runtime_Method error:

<MediaElement  AutoPlay="false" Name="mediaBox"  Source=""  />
in javascript file: sender.findName("mediaBox").setSource(sender,"http://play.rbn.com/play.asx?url=cspan/cspan/wmlive/cspan1v.asf");

Why can't I dynamically assign the streaming source without throwing an error?

Any suggestions would be greatly appreciated.

Hi:

  setSource is used for the downloaded viedo:

  In your case you should try:

sender.findName("mediaBox").source="http://play.rbn.com/play.asx?url=cspan/cspan/wmlive/cspan1v.asf";
