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.
Slurchin is a Web interface to a Quickcam for Notebooks Deluxe connected to a NSLU2 running Linux. (It might work for other webcams, hardware, and OSes, but it hasn't been tested.) The application allows the user to take pictures and see them through the Web. It also allows the user to check if the necessary drivers to make the camera work are installed and loaded. It requires w3camd to be installed in the device.
WebcamStudio is an application for creating your own TV studio on your computer for broadcasting through a virtual webcam.

It features special effects, text overlay, video source transition, animations, and faces.
dabba is a set of distributed network monitoring tools for Linux. Its main use is to gather or scatter actions on a network such as traffic capture, replay, generation, or monitoring. It was inspired by the Dabba Walla system in Mumbai where meals are regrouped and dispatched throughout the city with a high efficiency rate, every day of the year. The project has three main components: libdabba, a low-level zero-copy network library, dabbad, a multi-threaded task manager and IPC query processor, and dabba, a CLI for communicating with dabbad and submitting tasks.
