Abstract
A hardware encoder has a block analyzer configured in hardware to selectively alter encoding parameters of a coding unit or a coding tree unit in response to encoder conditions and an analysis of the coding unit or coding tree unit. A stream analyzer operating as a software process on one or more computational cores selectively alters encoding parameters in response to evaluation of parameters associated with a stream of video data.
