The Rainbow add-on for Firefox is an early developer prototype 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. Check out the included example to see how simple it really is!

This pre-alpha version of the add-on only works with the Firefox nightly builds on a Mac. We’re working hard to extend support to Windows, Linux and 64 bit platforms as soon as possible (there are currently no plans to support earlier versions of Firefox). We recommend going through the README, which lists known issues.
