(I don't think this is correct but it is not related to 
va-api at all, consider testing mplayer -vo gl, it is 
very fast because it does not need CPU conversion of 
YUV->RGB.)

I am certainly no expert for va-api, but I wonder if 
you already realized that ffmpeg and ffplay (the 
applications) do not support va-api in any way, 
libavcodec contains code that application may use 
to decode using va-api, see vlc source code and 
the linked MPlayer patch for examples.
