Hi,
I went through a couple of the provided OpenCV examples provided here: https://github.com/Itseez/opencv/tree/master/samples/android
It seems, all of them actually build an activity that implements the `CvCameraViewListener` interface and do their magic when the listener is called back through `onCameraFrame`. If the surface is however not visible, the callback doesn't happen, which makes me wonder: How does one implement a video data processing app with the need to show a preview image? I'm guessing some manual labour with `org.opencv.highgui.VideoCapture` but I still have to find sample code, tutorials or documentation on this.
Any pointers (even just code snippets to examples) are greatly appreciated!
