一种面向游戏仿真引擎的并行视频播放插件系统设计

With the help of video player plugins of game engines, designers can establish the virtual stage more easily. Videos make the virtual stage more colorful and richer. However, the present known plugins for game engines (e.g. CryEngine3) don't performs well in front of relatively big videos. For example, it can achieve only 16fps in general while playing forty videos at the same time, but the baseline of designing virtual stage is 30fps. Based on full analyses of both software and hardware, this paper aims to find the limits of improving frame rates, and then provide the methods for optimizing video player plugins in software architecture, namely multi-threads optimization. Based on the optimization of video player plugin of CryEngine3,experiments show that our optimization can improve the frame rate from 16fps to 54fps while playing 40 videos at the same time, which makes the establishment of large scale virtual stage become true.
