After releasing an application called AirPlayer that allows you to stream video to your mac from your iPad using Apple’s built-in AirPlay services, TUAW’s Erica Sadun has now released AirFlick that transmits data to any Apple TV 2 outside of iTunes. According to Erica, AirFlick offers the potential of real-time transcoding of otherwise unsupported file types into Apple TV-compatible data. It also allows you to open videos located on the internet by pasting a URL and clicking the play button. Erica was able to watch a number of Internet Archive (archive.org) mp4 videos on a big screen TV by browsing that website, selecting URLs, and opening them with AirFlick.
This is how she explains how the AirFlick works:
