12.4. Video Transfer

In this phase, you will encode and transfer the video feed from your video capture device to your chosen video playback mechanism. If you just want to view the video on the computer that hosts the video capture mechanism itself, then you have almost no work to do. On Linux, you can just launch XawTV. Video transfer is still occurring within the confines of your computer, but your operating system is taking care of it automatically. Video for Linux (v4l) makes the video feed available to applications such as XawTV. Windows XP doesn't really have a built-in tool to view live video, but Windows Movie Maker works with Video for Windows (VfW), and will do in a pinch.

However, you will probably end up implementing the video transfer mechanism across a network. Video can't travel natively over IP; it needs to be encoded. In the Linux world, most people use Camserv, which you can find at http://sourceforge.net/projects/cserv/.
