Abstract
A video decoding method and apparatus receives a motion compensation shader command, such as a packet, for a programmable shader of a 3D pipeline, such as programmable vertex shaders and pixel shaders, to provide motion compensation for encoded video, and decode the encoded video using the programmable shader of the 3D pipeline. As such, the programmable shader of a 3D pipeline is used to provide motion compensated video decoding as opposed to, for example, dedicated hardware, thereby, among other advantages, eliminating the need for the dedicated hardware.
