Connect a USB camera (any cheap camera will do) to your computer. Run the JMF Registry application (installed together with JMF) as shown below.
JMF Registry shows the detected capture devices together with the supported format for each device. If no capture device is shown, use the 'Detect Capture Devices' button to try to detect the devices.
After confirming that JMF is able to capture the video device vfw://0, start the VideoReceive application, and then the VideoTransmit application. Make sure you are using an available port on your computer (you learned earlier in this unit how to check which ports are being used), and remember to substitute your IP address.
