Mozilla Labs: Rainbow

The Rainbow add-on for Firefox is an early developer PROTOTYPE from Mozilla Labs that enables web developers to access local video and audio recording capabilities using just a few lines of JavaScript. The add-on generates files encoded in open formats: Theora (for video) and Vorbis (for audio) in an Ogg container. The resulting files are accessible in DOM using HTML5 File APIs, which may be used to upload them to a server.
