There is a command line tool, vdpauinfo. When this runs correctly, it
will output what VDPAU features your hardware supports, eg (a
snippet):

  Decoder capabilities:

When you can run vdpauinfo and get a similar output, mplayer will work
correctly. I suspect there are more configuration steps to get
vdpau-va-gl to work correctly than just installing the package - this
page [1] says you must set VDPAU_DRIVER=va_gl in your environment; did
you do that?

You might find people with more experience of vaapi/vdpau-va-gl on
Gentoo on the Gentoo forums than on here.

Cheers

Tom
