提出一种基于操作树的移动设备视频处理方法和系统实现,将视频编辑处理从移动端迁移到服务端,建立了前后端操作公共集并设计了一种操作树构建算法,根据操作集实现操作树的构建、解析以及视频自动处理过程.经实验验证,本文提出的方法可将处理效率提高两个数量级,丰富了处理类型并解决了移动端无法处理高清视频的瓶颈.
A video processing method and the system implementation are presented based on operation tree that migrates the process of video editing to server.A common operation set of front and rear ends is created and an algorithm of constructing operation tree is proposed.The construction,parsing process of operation tree and the automatic video processing are based on the operation set.The experiment verifies that this method effectively improves the processing efficiency of two orders of magnitude,enriches video processing types and solves the bottleneck of high-definition video processing in mobile devices.
