I require students in the first semester at Raritan Valley Community College Interactive Media Program to include live video via their Flash projects. Some students will capture some live video. Some like to get it from the web but today the web has less and less downloads especially when you are looking for a particular topic. For example a student was doing some video of interstellar events like sun spots. Nasa has video on it.
There is a product that is open source that seems to let you capture most if not all incoming video via a web site and probably any input.
VideoLAN – VLC media player
It is a bit geekish to get the capture to work, but we succeeded with some trial and error to capture the video from Nasa into MP4 format and then we swiftly ran it through the Flash media encoder to Flash Video format for the student’s project.
