Method and system for decoding multi-process video

Abstract

The invention provides a method for decoding multi-process video. The method comprises the following steps: establishing multiple corresponding independent decoding processes for different video cards of a video decoding system; and selecting decoding processes corresponding to the video cards to decode video data. The invention further provides a multi-process video decoding system. The multi-process video decoding system comprises a decoding process scheduler, wherein the decoding process scheduler comprises a process setting module and a process distribution module; the process setting module establishes multiple decoding processes for different video cards of the video decoding system; and the process distribution module selects the decoding processes corresponding to the video cards to decode the video data. By adopting the above technical scheme, the business process and decoding of video decoding software are realized by different processes, and the video decoding software can be decoded through a plurality of decoding processes to realize load balancing, therefore, the system hardware resources can be fully utilized and the characteristic of quick recovery of processes during crashed decoding process can be realized.

Description

technical field [0001] The invention belongs to the technical field of video decoding, in particular to a multi-process video decoding method and system. Background technique [0002] Traditional video processing software usually adopts the scheme that the business process and video decoding are in the same process. Since video decoding takes up more computer memory resources, it is easy to cause the application to crash. At the same time, limited by the 32-bit operating system, a single process cannot fully utilize computer hardware resources, and video decoding cannot fully utilize computer hardware resources. [0003] When a single process handles business processes and video decoding at the same time, when the application crashes due to a defect in the video decoding module, it cannot quickly resume normal operation. Contents of the invention [0004] The purpose of the present invention is to provide a method and system for multi-process video decoding. The business...
