Failed when reopen video using WebcamPanel

[germanchaparro]

Hi sarxos

I started to play with your api by modifying your example TakeSnaphotFromVideoExample.java. I created a Stop button to stop the capture from the webcam by using the method panel.stop().

private class StopAction extends AbstractAction{

    public StopAction() {
        super("Stop");
    }

    @Override
    public void actionPerformed(ActionEvent e) {

        btStart.setEnabled(true);
        btSnapMe.setEnabled(false);
        btStop.setEnabled(false);

        panel.stop();
    }
}

This seems to be working well but, when I try to start the video again with the Start button which calls the method panel.start() I get the following exception:

Exception in thread "pool-1-thread-1" java.lang.IllegalThreadStateException

It seems to be similar to the bug "Dispose Webcam #121" but in that thread you never talk about start the capture again without closing the application.

I am working in this environment:
Webcam Capture version: webcam-capture-0.3.10-RC6
Java version: 1.7.0_51-b13
OS: OS X 10.9.2
Name of Webcam: FaceTime HD Camera (Built-in) 0x1a11000005ac8510
Architecture: 64 bits

I already try the suggestions you gave in Dispose Webcam #121 with no successful results.

Thanks in advance

PD: Great API !

Hi @germanchaparro,

Indeed, I was able to reproduce it using source code you provided on top of RC6 tag, however I do not confirm its existence in newest SNAPSHOT build. I guess it was fixed by @syliks who did d36900b - thanks Sylwia!

Can you please try again with this one: webcam-capture-0.3.10-20140310.191743-24.jar?

Seems like I should release RC7 ASAP ;P

Hi @sarxos

This jar works perfectly well. I will work with this one and as soon as you release the new version I will try it again.

Thank you very much :)

PD: Congratulations for this API, it is great

I'm glad it works :)
