Well, let's say sleeping ;-)

Yes, I it is not only partial, but also bit rotten.  It is not really working 
in the current framework.   But when I made this small excursion into ffmpeg, 
it took me only this few lines of code and a few hours to implement MPEG 1/2 
output.  Any form of ffmpeg output should be fairly trivial.  input may be 
different.

The scenedetection in piave is working.  Scenes are detected via the 
"new-scene"-flag as provided in DV or via a sudden jump in the recording time 
tag of a frame.  Together this is pretty relyable.
