The
video library allows Processing to display QuickTime video files and
grab video data from a camera. Video
can be captured from USB Cameras, IEEE 1394 Cameras, or Video Cards
with composite or S-video input devices connected to the computer.
Video can be loaded
from QuickTime files located on your computer or anywhere on the Internet.
For this library to work, it is necessary to have QuickTime for Java
installed on your computer. Download and install QuickTime and do
a custom installation, making sure the QuickTime for Java option
is selected.
You also need video driver software for translating from the proprietary
format of your video source into commonly used video functions. You
can get this software from the makers of the video hardware.
If you are not using an Apple computer, you will also need a VDIG,
a video driver that translates from your hardware to the video functions
used by QuickTime. This software may be included in the software provided
by the maker of your hardware, or you can download the free VDIG available
at http://www.vdig.com and check if it is compatible with your video
camera. The free VDIG is slower than many you pay for. |
