Silverlight 1.0 AG_E_UNKNOWN_ERROR with Error Code 1001

Asked By 0 points N/A Posted on -

I am currently working on a project that uses a lot of video and pre-rendered image sequences. I am using Silverlight 1.0 runtime with JavaScript application when working with this project. My project seems to be working fine on Windows XP using IE 7 browser but when I tried to run it on Windows Vista and IE 7; I unexpectedly got an error saying, “AG_E_UNKNOWN_ERROR with error code 1001 regarding a "Media Error".” What is more fascinating is that the project continued to work normally after ignoring the error message. Does the error message have no vary on my project? What will I do to eliminate getting that kind of error?

Please help me. I need some clear answers to my questions.

The error that you are getting is most probably a codec issue, and the 1001 Media Error that you are getting is often thrown when there is an unrecognized codec that is being used.

In case the video keeps playing OK, then that will mean it is probably just an issue that has to do with the video file's header, and therefore you will need to try re-encoding the videos using  a different format to see if that's really the issue. In case the problem is not solved that you will to contact the Silverlight support admin and let them help you out in solving that issue.
