This bug seems to have been closed incorrectly, LP:446040 refers to a 
different problem: "vdpau video output breaks fullscreen playback at least on 
some GPUs"

This bug (#617940) is about a harmless, but maybe confusing or annoying error 
message emitted by software that is linked against libvdpau.so.1 (mplayer, 
iceweasel, ..) but run on a system with no vdpau acceleration - without 
nvidia hardware (or nvidia drivers). vdpau initialization fails, an error is 
printed, vdpau is not used (but normal X methods instead), so no problems for 
the applications at all.

The "problem" can be easily be reproduced by running vdpauinfo (from the 
vdpauinfo package).
