I moved your question to the correct sub-forum, since you are asking about Wowza Media Server version 3.
To answer your question, you can add CORS headers to your Wowza server. However, you will need to update to at least 3.5 or above, and add the cupertinoUserHTTPHeaders property to your application's HTTPStreams configuration. This is discussed
on another thread in adding the CORS headers.
