Hello everyone!

I’m implementing an Android App to broadcast live video to wowza server application, if I use WowzaConfig class to set the properties of the streaming, the code works fine, but if I use WZBroadcastConfig instead (because it allows to record video on local storage during broadcast), the logcat says that Host is null when I start streaming

This is the working code:

```auto
     // Specify the broadcast configuration parameters
        WowzaConfig broadcastConfig = this.goCoder.getConfig();
        // Update the active config to the defaults for 720p video
        broadcastConfig.set(WZMediaConfig.FRAME_SIZE_1280x720);
        // Set the address for the Wowza Streaming Engine server or Wowza Cloud
        broadcastConfig.setHostAddress(host);
        // Set the name of the stream
        broadcastConfig.setStreamName(path);
        broadcastConfig.setUsername(username);
        broadcastConfig.setPassword(password);
        broadcastConfig.setPortNumber(port);
        broadcastConfig.setApplicationName("test");
        broadcastConfig.setVideoProfileLevel(new WZProfileLevel(WZProfileLevel.PROFILE_MAIN));
        // Update the active config
        this.goCoder.setConfig(broadcastConfig);

```

and this is the not working code:

```auto
    WZBroadcastConfig config = new WZBroadcastConfig(WZBroadcastConfig.FRAME_SIZE_1280x720);
        WZMP4Writer mMP4Writer = new WZMP4Writer();
       mMP4Writer.setFilePath(Tools.VIDEO_PATH + "/" + "recorded.mp4");
        config.registerVideoSink(mMP4Writer);
        config.registerAudioSink(mMP4Writer);
        config.set(WZMediaConfig.FRAME_SIZE_1280x720);
       config.setHostAddress(host);
       config.setStreamName(path);
        config.setUsername(username);
       config.setPassword(password);
        config.setPortNumber(port);
        config.setApplicationName("test");
        config.setVideoProfileLevel(new WZProfileLevel(WZProfileLevel.PROFILE_MAIN));
       goCoder.setConfig(config);

```

host,username,password and port variables are the same for both snippets.
