VDPAU (Video Decode and Presentation API for Unix) is an API developed by NVIDIA which offloads the processing of various video codecs onto the GPUs of certain models of NVIDIA video cards. This brings the features of PureVideo, currently available in the Windows drivers, to the linux platform. Offloading the processing of video to the GPU can drastically lower CPU utilization, and allow lower-end frontends to still process highly intensive video codecs like h.264.
