No audio in VLC.

I already created an app with the library but no audio at all in VLC. Why it happen?

My code in MainActivity.java

package my.intellij.androidrtp;

        setContentView(R.layout.activity_main);

        mSurfaceView = (SurfaceView) findViewById(R.id.surface);


        // Sets the port of the RTSP server to 1234
        SharedPreferences.Editor editor = PreferenceManager.getDefaultSharedPreferences(this).edit();
        editor.putString(  RtspServer.KEY_PORT, String.valueOf(1234));
        editor.commit();



        // Configures the SessionBuilder
        mSession =  SessionBuilder.getInstance()
                .setCallback(this)
                .setSurfaceView((net.majorkernelpanic.streaming.gl.SurfaceView) mSurfaceView)

        String ip, port, path;

        // Starts the RTSP server
        this.startService(new Intent(this,RtspServer.class));

        Log.d("test", "1");

Hi,

Try to modify the destination port of the audio track in SessionBuilder.java I modified it from 5004 to 5010 and it worked.

	if (session.getAudioTrack()!=null) {
		AudioStream audio = session.getAudioTrack();
		audio.setAudioQuality(mAudioQuality);
		audio.setDestinationPorts(5004);
	}

I used this URL to connect to my RTSP server: rtsp://@MY_IP:1234/ P.S. Don't forget the "/".

Still not working after changing the destination Port in Session.java
