Smooth Streaming Error

Hello,

We had built our silverlight cilent to play smooth streaming from Wowza.

But it cannot play smooth streaming and shows “3222 an error has occurred” error message.

The wowza access log is

INFO application app-start _definst_ vod2/_definst_
INFO smoothstreaming connect 1480193075 -
INFO stream create sample.mp4 
INFO stream destroy sample.mp4 -
INFO smoothstreaming disconnect 1480193075 -

But the Wowza sample player in examples\SimpleVideoStreaming\clientSilverlight works great and access log is

INFO application app-start _definst_ vod2/_definst_
INFO smoothstreaming connect 1634881568 -
INFO stream create sample.mp4 -
INFO stream play sample.mp4 -
INFO stream stop sample.mp4 -
INFO stream destroy sample.mp4 -
INFO smoothstreaming disconnect 1634881568 -

Then we built wowza sample player source code to test.

It shows “Streaming Error: Failed to download mainfest:d” error message and the access log is same with first situation(without “INFO stream play”).

Is there any information to help us?

Thanks,

Roy
