Well, you quoted only a small part, so it's hard to say much except that
VPDAU simply isn't working according to the error.
It is entirely possible VDPAU just doesn't work for that specific video
or video codec, but there is too little output.
Though there is more wrong with your MPlayer, you said:
MPlayer SVN-r37313 (C) 2000-2012 MPlayer Team
However r37313 is from 2014, and we updated the string correctly the
last years.
