Constructor Detail

DisplayWebcamVideo

public DisplayWebcamVideo(java.lang.String driverName,
                          java.lang.String deviceName)

Construct a DisplayWebcamVideo which reads and plays a video from an attached webcam.

Parameters:

driverName - the name of the webcan drive

deviceName - the name of the webcan device

Method Detail

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).
