Yawcam -> Settings -> Camera
Yawcam version 0.3.0 and above works with all DirectX compatible video capture devices.
All video devices Yawcam has found will be visible in the camera list.
If the list is empty, go back to the main window and try to detect
the camera. This is done by clicking "Settings ->
Detect Camera..." in the text menu.
To access your device's native driver settings, like brightness,
contrast and image size, go back to the main window and click
"Settings -> Device (X)" in the
text menu. (Where X is the name of the selected video device.)

If you want to be able to capture a video stream from your computer's
desktop, you can use "VH Screen Capture Driver". Get
