The YouTube assignment submission plugin is for the Moodle assignment (2.3 and above). It allows teachers to accept video submissions from students. The video is recorded by webcam OR uploaded from the student’s pc/device directly to YouTube.
The mod code is available only through Justin’s site currently while it’s submission to Moodle.org is pending. Download it here: http://poodll.com/youtube-assignment-submission/. The YT Assignment uses Youtube’s public API (so no content server or other installations are necessary for this to work, students will just need a Google account).
