In the spirit of releasing early and releasing often – we are proud to bring you version 0.2 of Rainbow – an experimental Firefox add-on from Mozilla Labs that exposes audio and video recording capabilities to web pages.

What’s new in this release?

• We now support both audio and video recording on Windows, and audio recording on Linux.
• We added preliminary support for writing multiplexed media frames to a websocket.
• JS callers are now able to specify custom video resolutions, encoding quality, audio sampling rates and channels.
• Numerous bug fixes, such as behaving correctly on Mac OS X 10.5 (Leopard), and generating correctly encoded OGG files (the audio tracks of which were previously unplayable by Firefox).

For a full list of changes, check out our commit logs – or even better – contribute on Github! Also, don’t forget to read the README for additional information.

We’re always delighted to hear from you – join in on our discussion forum or IRC channel. Happy hacking!
