libvcvideo is targeted as a super-simple cross platform video device library. It's starting with the most basic features and building up, all while keeping a simple API and strong documentation for beginners. Currently only select devices are supported, but as more hardware becomes available that will change. Right now it only has limited compatibility with Linux Webcam devices that use the original V4L specifications and output RGB24 data. This is actually a very large set of devices, as that is the generic description for most spca5xx and gspca devices. Though incomplete, if you have the right device it is very simple. Counting variable declaration, you only need four lines of library code to get a frame from a camera.
mimms is an MMS (e.g. mms://) stream downloader. mimms is a program designed to allow you to download streams using the MMS protocol and save them to your computer, as opposed to watching them live. Similar functionality is available in full media player suites such as Xine, MPlayer, and VLC, but mimms can be quicker and easier to use.
