      • main

        public static void main​(java.lang.String[] args)
        Takes a FFMPEG webcam driver name, and a device name, opens the webcam, and displays its video in a Swing window.

        Examples of device formats are:

        OS Driver Name Sample Device Name
        Windows vfwcap 0
        Linux video4linux2 /dev/video0

        Webcam support is very limited; you can't query what devices are available, nor can you query what their capabilities are without actually opening the device. Sorry, but that's how FFMPEG rolls.

        Parameters:
        args - Must contain two strings: a FFMPEG driver name and a device name (which is dependent on the FFMPEG driver).
