Media Failed Event on attempt to load MMS

May 20, 2009 at 6:05 PM


I've ended up switching the streaming server side to a WMS server, but attempting to load an mms:// URL results in a MediaPlayerFailed event, with the exception being "The source filter for this file could not be loaded.".  A MediaElement works with the source, but is unstable with streaming media (there is an open Microsoft Connect ticket, #451480).  Using the WMS http protocol, MediaKit works, but I seem to remember a benefit to using mms as a source.

So, any idea why using an mms URL would fail, or is there no real drawback anymore to using http?  I'm using Server 2008 with Windows Media Services, and current development machine is running Vista.

Hello Mike,

I have exactly the same problem. I also tried other stream formats with no success.

If you find out the solution first let me know please. I'll do the same.
