The fine folks at Mozilla Labs announced a pre-alpha add on for Firefox that enables recording audio and video directly from the browser.
We’ve experimented with audio recording in the browser as part of the Jetpack prototype earlier, and want to revisit the idea. There have been great strides on video playback recently, but there’s still some work to be done before users can create multimedia content for the web, on the web.
There are ways to do this already but they all require proprietary technologies like Flash and Java. What the Rainbow extension could do as it matures is suggest ways that creating media become standard features in the browser. I really like that idea, of a browser directly supporting the creation of peer media creation, not just access and sharing.
The add on only works with the Mac version of the current nightly build series. The developers are working hard to expand support to Windows, Linux and 64-bit systems. Currently Rainbow encodes Vorbis and Theora using the Ogg container though future plans include adding support for WebM/VP-8 as well as streaming.
