Detailed Description

This is the interface for video input devices.

Each VideoInput should represent exactly one webcam (or similar device). The interface for querying the camera is provisionally done, but needs more testing of how it actually works. Most of the values are faked. TODO: separate the process of finding cameras from this class. It could be implemented as a static method. The available cameras and all created VideoInput objects should be stored in a MediaHandler, mapped by an index for retrieval by ActionScript. TODO: design a useful interface for starting, stopping and attaching the video data. VideoInputGst has some functionality here, but it is not generic enough, relying on too many gst-specific implementation details.
