Abstract: One video encoding method includes: performing a first part of a video encoding operation by a software engine with instructions, wherein the first part of the video encoding operation comprises at least a motion estimation function; delivering a motion estimation result generated by the motion estimation function to a hardware engine; and performing a second part of the video encoding operation by the hardware engine. Another video encoding method includes: performing a first part of a video encoding operation by a software engine with instructions and a cache buffer; performing a second part of the video encoding operation by a hardware engine; performing data transfer between the software engine and the hardware engine through the cache buffer; and performing address synchronization to ensure that a same entry of the cache buffer is correctly addressed and accessed by both of the software engine and the hardware engine.
