Camera.FaceDetectionListener (FaceActivity) is not working in this source.

[@override](https://github.com/override)  
public void onFaceDetection(Camera.Face[] faces, Camera camera) {  
…  
}

Camera.Face[] faces is always empty.

I simply run gocoder sample android app ([https://github.com/fabiojapa/gocoder-sdk-samples-android](https://github.com/fabiojapa/gocoder-sdk-samples-android)) provided by you guys.  
with SDK compile ‘com.wowza.gocoder.sdk.android:com.wowza.gocoder.sdk:2.0@aar’
