RSTP video stream freezes the program while connection is lost..

edit

Helo,

I have a fairly simple Java app which connects to few cameras through rstp stream, grabs the image and shows it in swing JFrame usnig OpenCV SwingWorker. My reconnect() method looks like this:

public void reconnect(String address) {
    System.out.println("connecting...");
    if (new ConnectionTester().pingHost(NETWORK_HOST, NETWORK_PORT, 50))
        capturedVideo.open(address); // networkAddress
    System.out.println("Still running");

    if (!capturedVideo.isOpened()) {
        System.out.println("Error while opening the camera!");
    }
}

Because of a weak WiFi signal ( connection breaks) between the camera and my pc I sometimes get result like:

    connecting...
    Connection avaliable

and the program hangs while performing capturedVideo.open(address);

or on VideoCapture.read() method:

if (isOpened) {
        capturedVideo.read(cameraMat);

Is there any way to avoid such situations by maybe waiting a set amount of time before stopping everything and reconnect again ?

Thanks!
