Currently, in order to get VDPAU working you're required to compile mplayer with vdpau option enabled. Even though there are some PPAs, their content is not entirely reliable and still dosen't gurantee a 100% working solution for everybody.
VDPAU also makes playback of high definition content on older hardware possible, since the burden is shared between the CPU and GPU.
VDPAU (Video Decode and Presentation API for Unix) is an API designed by NVIDIA for its GeForce and later GPU hardware, released in november 2008,allowing video programs to offload portions of the video decoding process and video post-processing to the GPU video-hardware.
