Abstract:
1. A method comprising: receiving an encoded video bitstream, the video bitstream comprising intra-coded frame data and inter-coded frame data, wherein the inter-coded frame data comprises multiple intra-coded macroblocks that do not depend on data from a corresponding reference macroblock and multiple inter-coded macroblocks that depend on data from a corresponding reference macroblock; decoding the intra-coded frame data using a central processing unit; transferring the intra-coded frame data to a graphics processing unit; using the graphics processing unit to: decoding the inter-coded frame data using the central processing unit; identifying two or more inter-coded macroblocks of the inter-coded frame data; packing the two or more inter-coded macroblocks together into a data packet containing only inter-coded macroblocks; transferring the data packet containing only inter-coded macroblocks to the graphics processing unit; and using the graphics processing unit to:
