Abstract
A method for flexible encoding is described herein. The method includes selecting a largest coding unit size of a current frame based on a largest coding unit size of a prior frame and determining a coding unit processing order based on heuristics and the largest coding unit size of the current frame. The method also includes determining a rate distortion metric of the current frame based on the largest coding unit size and in response to an exit criteria being met, processing the coding units of the current frame in the coding unit processing order.
