[Libva] Status of libva and mplayer/ffmpeg?

I must correct myself here, the -va switch indeed works, if one supplies 
a file to be played to mplayer ;-)

So now I do this:

~/mplayer -va vaapi -vo vaapi BBC\ Children\ In\ Need\ 2010.mp4

(which is an mp4 file with h264 inside)

Output:

...

The cpu usage doesn't drop and the last message proves to me that hw 
accel isn't used, but ffmpeg's internal h264 decoder is used instead.

What am I doing wrong here?
