The problem with ffmpeg IMHO is that it is a moving target (as is also declared 
on their website). It is almost impossible for ParaView to keep up and just 
arbitrarily picking any revision is no solution either, because that will cause 
a lot of trouble for packagers.

<shameless_plug>I suggest you give the included Ogg/Theora writer a 
try.</shameless_plug>.
