WOWZA player not working android app

Wowza GoCoder SDK
1

I made a basic wowza player using the instructions given here :

https://www.wowza.com/docs/how-to-play-a-live-stream-with-wowza-gocoder-sdk-for-android

Note : the streaming part is working and is visible on the wowza streaming cloud website.

The connection settings are done as shown here :

https://www.wowza.com/docs/how-to-connect-to-wowza-streaming-cloud-with-gocoder-sdk-for-android

I am using wowza cloud streaming as the server however I get the following error :

This is the code I am using :

    private WOWZPlayerView mStreamPlayerView;
    private WOWZPlayerConfig mStreamPlayerConfig; <br>   private WowzaGoCoder goCoder;@Override<br>protected void onCreate(Bundle savedInstanceState) {<br>        super.onCreate(savedInstanceState);<br>setContentView(R.layout.activity_player);<br>goCoder = WowzaGoCoder.init(getApplicationContext(), "license_key");<br>mStreamPlayerView = (WOWZPlayerView) findViewById(R.id.vwStreamPlayer);<br>mStreamPlayerConfig = new WOWZPlayerConfig();<br>mStreamPlayerConfig.setIsPlayback(true);<br>mStreamPlayerConfig.setHostAddress("host_address");<br>mStreamPlayerConfig.setApplicationName("app-xxxx");<br>mStreamPlayerConfig.setStreamName("stream_name");<br>mStreamPlayerConfig.setPortNumber(1935);<br>mStreamPlayerConfig.setAudioEnabled(true);<br>mStreamPlayerConfig.setVideoEnabled(true);<br>mStreamPlayerView.setScaleMode(WOWZMediaConfig.FILL_VIEW);<br>WOWZStatusCallback statusCallback = new StatusCallback();<br>mStreamPlayerView.play(mStreamPlayerConfig, statusCallback);}<br><br>    class StatusCallback implements WOWZStatusCallback{<br>        @Override<br>public void onWZStatus(WOWZStatus wzStatus) {<br>        }<br>        @Override<br>public void onWZError(WOWZStatus wzStatus) {<br>        }<br>    }

Same here. Have you found any solution?

Hi,

I have found some solution for the problem as follows.

Step 1: First initialise the GoCoder inside onCreate().

WowzaGoCoder goCoder = WowzaGoCoder.init(getApplicationContext(), “GOXX-XXXX- XXXX-XXXX-XXXX-XXA7”);

Step 2: Maintain some delay between Wowza player configuration and ‘play’ method of Wowza player view.

mStreamPlayerConfig = new WOWZPlayerConfig();
mStreamPlayerConfig.setIsPlayback(true);
mStreamPlayerConfig.setHostAddress("your-server-ip");
mStreamPlayerConfig.setApplicationName("live");
mStreamPlayerConfig.setStreamName("myStream");
mStreamPlayerConfig.setPortNumber(1935);<br><br>new Handler().postDelayed(new Runnable() {
    @Override
    public void run() {
        mStreamPlayerView.play(mStreamPlayerConfig, this/*WOWZStatusCallback*/);
    }
}, 1000);

Hello,

Please make sure that your run method to create the delay looks like this:

 final Handler handler = new Handler();
        handler.postDelayed(new Runnable() {
 @Override
 public void run() {
 *WOWZStatusCallback statusCallback = new StatusCallback();*
 *mStreamPlayerView.play(mStreamPlayerConfig, statusCallback);*
 *}*
 *}, 1000);*
 *}*
*}*
