Popcorn is a Mozilla project to make video work more “like the web.” It aims to transform video on the internet.
Popcorn allows users to combine video with content pulled live straight from the web. Popcorn videos behave in a way the web does; charismatic, effective, full of useful links and absolutely changeable. So in all popcorn makes your video viewing experience much more reciprocal.
With popcorn you can attach live feeds from a Twitter, Facebook or even Flickr page using tags. and have them come up live in your video showing the viewer the latest images or statuses from that tag.
