The yt4pdf package uses the rmannot package to embed a special SWF
file to play the YouTube videos. There is a complete set of buttons
that come with the package to control the video: play, pause, stop loading, rewind, load a video by its YouTube video ID, and a button to
view a video on the YouTube web site. Adobe Acrobat 9 or later is required to author an document; only Adobe Reader 9 is need to view the created yt4pdf document.
Advanced examples will appear, in time, on the AcroTeX Blog
Now I simply must get back to my retirement!
