Google just announced the release of Chrome 21 stable release of the popular web browser. Apart from a long list of bug and security fixes, there are a few new features.
The first new thing is the introduction of the getUserMedia API, which allows web apps to directly access your web camera and microphone without a plug-in as long as you permitted it. In the past many web apps use Flash to connect to the web cam but this could slow things down. This new API makes realtime communcation through web app faster and easier. It also brings creative use to the web cam, such as taking a photo of yourself, uploading to Chrome Lab, converting it into a line drawing and asking a robot in London to draw out your portrait in a patch of sand (this is actually possible in the past using Flash but now you can play this without Flash plug-in). Google also suggested you to try these two web apps: Webcam Toy and Magic Xylophone.
A few other new features of Chrome 21 include expanded support for gamepads, support for Mac Retina high resolution screen and deeper Google Cloud Print integration, you can learn more about these from Google’s official release.
