Por que o mplayer não funciona com o VDPAU?

Estou tentando reproduzir um arquivo de vídeo HD, o comando para reproduzir o vídeo é:

mplayer -vo vdpau -vc ffh264vdpau

Você instalou o driver nvidia? Isso instalará o libvdpau que lhe dará suporte ao vdpau. Instale o driver via drivers de hardware ou centro de software.
