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.
Smitten differs from traditional media centres in three major ways. It contains no media playback at all, which makes it very small (and suitable for porting to embedded systems) and quick to initialize. It targets a TV display and interface, which means there's less information on any particular screen, and a much simpler control interface consisting of left, right, up, down, and select. No mouse is required. It is also highly skinnable, and cross-platform to most systems. Essentially, it provides an easy-to-use menu system that allows the user to navigate a hierarchy of files, and view them using an (external) tool.
SynScope is an offline visualization and alignment tool for time-varying signals acquired from multiple sources that may differ in offset and/or sample rate. SynScope allows you to define reference points that correspond to identical events between source pairs. It then estimates the offset and resample rate to link these sources. It maps sample time from one source to the other via a link equation. Signal alignment can be inspected with synchronous visualization or resampling. With synchronous visualization, linked signals scroll together according to the link relation. With resampling, linked signals are resampled to the highest sample rate and offset-compensated.
