Multi-core-based high-performance self-adaptive OpenHarmony video coding and decoding method

Abstract

The invention discloses a multi-core-based high-performance self-adaptive OpenHarmony video coding and decoding method, which comprises the following steps of: selecting a proper hard codec and a proper soft codec or simultaneously using the hard codec and the soft codec by automatically identifying the hardware capability of a system and the multi-core condition of a CPU (Central Processing Unit) of equipment; cPU multi-core self-adaptive optimization is performed on multi-file video coding and decoding and single-file video coding and decoding according to the core number of the CPU, a universal interface is finally presented to a user by adopting an optimal serial and parallel simultaneous coding and decoding method, the user does not need to perceive specific hardware and software configuration, and the user experience is improved. And the optimal video codec can be automatically used without knowing related knowledge of video coding and decoding of OpenHarmony.
