VDPAU is Video Decode & Presentation API for Unix.

The Video Decode part is the part that pushes the encoded video to the 
hardware decoder to decode it.

The Video Presentation part is the part that allows drawing the decoded 
video frames on screen.

So, the presentation part replaces the 
(designed-for-another-simpler-era's-video) Xv rendering with a 
more-full-featured rendering and drawing framework (that allows for much 
better OSDs and such).
