Abstract

Embodiments of a method and system for decoding video data are described herein. In various embodiments, a high-compression-ratio codec (such as H.264) is part of the encoding scheme for the video data. Embodiments pre-process control maps that were generated from encoded video data, and generating intermediate control maps comprising information regarding decoding the video data. The control maps include information regarding rearranging the video data to be processed in parallel on multiple pipelines of a graphics processing unit (GPU) so as to optimize the use of the multiple pipelines. In an embodiment, macro blocks of video data with similar deblocking dependencies are identified to be processed together. Deblocking is performed on a frame basis such that deblocking is performed on an entire frame at one time. In other embodiments, processing of different frames is interleaved. Embodiments increase the efficiency of the decoding such as to allow decoding of high-compression-ratio encoded video data on personal computers or comparable equipment without special, additional decoding hardware.
