摘要： To decode encoded video using a computer with a central processing unit and a graphics processing unit as a coprocessor, parameters applied to blocks of intermediate image data are transferred from the central processing unit to the graphics processing unit. When the operation being performed applies to a small portion of the blocks of intermediate image data, then the central processing unit can transfer to the graphics processing unit the parameters for only those blocks to which the operation applies. In particular, the central processing unit can transfer a set of parameters for a limited number of blocks of intermediate image data, with an indication of the block to which each set of parameters applies, which both can improve speed of operation and can reduce power consumption.

摘要： According to a first aspect of the innovations described herein video encoding, such as game video encoding, is improved with a goal to generate substantially constant video quality and the average target bitrate within a desired tolerance, which improves an overall user experience on video playback. An adaptive solution uses intelligent bias on bit allocation and quantization decisions, locally within a frame and globally across different frames, based on a current quality level and within an allowed bitrate variable tolerance. Bit allocation is increased on high complexity frames and redundant bits are avoided, which might have been wasted for static scenes and low complexity aspects. Statistics can be used from the encoding process. The solution can address similar video coding quality problems for video game recording on a variety of gaming platforms.
