Question

I’m trying to make some app that will play the stream from wowza.
That part is ok. But next i need to have some option in app, that will comunicate with wowza server. For example how to call a wowza server some method, how to call onConnect method … How to connect from wowza from a app and stay connected until i call a onDisconnect method???
If somebody have some info i will be very grateful… Thanks in advance…

VideoView.setVideoPath("some path") 

does the trick for playing…

You call call a method in a Wowza module using a HTTPProvider (http://www.wowza.com/forums/content.php?30-httpproviders). This gives you a url in your Wowza module which your app will be able to call over HTTP.

So for example you have your Wowza module running under the default of:

http://localhost:1935.

You can add a HTTPProvider to your VHost.xml, such as:

<HTTPProvider>
    <BaseClass>com.mycompany.wms.module.SomeModule</BaseClass>
    <RequestFilters>logout*</RequestFilters>
    <AuthenticationMethod>none</AuthenticationMethod>
</HTTPProvider>

This would let you call a url such as:

http://localhost:1935/logout?id=123456789

In the Java code for your module, you need implement HTTProvider2Base from which you create a onHTTPRequest method. The variables in the query string (so in this example: ?id=123456789) can be used in the method. You can also call methods in your module from here.

An example Java class that would use this call is as follows:

package com.mycompany.wms.module;

import com.wowza.wms.http.HTTProvider2Base;
import com.wowza.wms.http.IHTTPRequest;
import com.wowza.wms.http.IHTTPResponse;
import com.wowza.wms.logging.WMSLogger;
import com.wowza.wms.logging.WMSLoggerFactory;
import com.wowza.wms.vhost.IVHost;

public class SomeModule extends HTTProvider2Base {

public void onHTTPRequest(IVHost vhost, IHTTPRequest req, IHTTPResponse resp) {
    //Get the user
    String userId = req.getParameter("id");
    getLogger().info("Logging out user: " + userId );       

    logoutUser(userId);
}

private void logoutUser(String userId){
    //Do stuff here...
}

private WMSLogger getLogger(){
    return WMSLoggerFactory.getLogger(SomeModule.class);
}
}

Some gotchas:

• Scoping in onHTTPRequest seems to be outside of your instance so be careful of accessing properties in an instance of the module.
• I had to comment out the HTTPProvider node with HTTPServerVersion in it to get my one to work. It seemed to override all other HTTPProviders in my version of Wowza.
• I also had trouble with the Wowza running from the IDE not picking up calls to the url via Visual Studio. Once I put my changes into the service version, the calls worked fine.

The app I built which did this was largely based on the conversation in this article: http://www.wowza.com/forums/content.php?182-HTTPProvider-that-returns-detail-server-info
