Depends on your Ubuntu version. "ffmpeg" from recent Ubuntu (I didn't
check which versions other than 11.10) include --enable-vdpau (and
--enable-vaapi). However:

* Ubuntu now uses "ffmpeg" from the libav/"qatar" fork, not FFmpeg.

* If you compile from FFmpeg, then --enable-vdpau and --enable-vaapi
  are autodetected so you don't need to add those to your configure.
  Required dependencies are: libva-dev libvdpau-dev. For step-by-step
  FFmpeg compile instructions:

* The D in VDPAU stands for Decode, so it don't help the actual
  encoding, and it doesn't use the GPU, but an onboard acceleration
  chip, IIRC.

This is a subject which I am somewhat unfamiliar, so others may want to
add more accurate information or correct me.
