Parallel Multi-source Video Processing Based on Software Pipeline

摘要

A technology of parallel multi-source video processing based on software pipeline is presented, which has the features of reducing the design difficulty of the video processing applications, optimizing computing resource utilization rate and improving the real-time performance of the multi-source video processing with a complex algorithm. First, a kind of multi-task management system based on the multi-core CPU is introduced, which is used to schedule tasks and manage the loads of the computing resource, and on this basis, software pipeline is designed out. The software pipeline encapsulates the processing of a frame image as a task which will be submitted to the multi-task management system. Finally, the parallel multi-source video processing experiment was carried out to verify this technology. The results indicate that this technology could effectively improve the real-time performance of the multi-source and complex algorithm video processing, and it also has nice features in optimizing the computing resource utilization rate and load balance.
