write/convert JOGL animation to .mov or .wmv or ogg

I am an experienced Java programmer but 100% clueless as to graphics programming, so this may sound dumb, but anyway ...

All tutorials I''ve encountered talk about displaying OpenGL/JOGL apps in an applet or native window, but how do I output the result of my programming to some video format? So I can upload it to YouTUBE or Vimeo, for example. You _DO_ see a lot of JOGL examples on YouTUBE, so it must  be possible, but I haven't been able to figure out how.

Is there, for example, something like an OggStream class somewhere, that you can somehow write your frame buffer to, or something?
