Looks like it would work with a simple line like

mplayer -vc ffh264vdpau infile

Recent ffmpeg has disables multithreaded decoding with vdpau.
Though it doesn't seem to affect anything in this case.

With x264 you shouldn't need fancy post processing as it's built in.

It seems the mysterious $1 ... options mess things up, though you have 
-vf scale you probably need to put it somewhere else!

It falls back to software dec.
