摘要:
在飞行试验中,机载视频数据是试飞测试数据中的重要组成部分。目前机载记录视频数据为独立的M2T文件,现有视频播放软件只能对单路视频文件进行回放。为解决机载多路视频数据同步回放的问题,提出了一种基于C/S模式的多路视频同步回放技术方案,服务器端进行视频文件读取控制,客户端进行视频解码显示。首先介绍了FFMPEG的基本概念,然后论述了系统的总体设计方案,重点介绍了服务器端和客户端的设计与实现。该系统采用C++语言进行设计,服务器采用TCP/IP协议与客户端进行数据交互。软件设计利用模块化和多线程的思路,提高处理效率,保证功能的可扩展性。目前该软件已成功应用于多个型号任务多路视频同步回放中,实际应用效果表明该系统工作稳定,能够有效提高型号试飞效率。
Abstract:
In flight test,airborne video data is an important part of flight test data. At present,airborne recording video data is a singleM2T file. A single video file can be replayed at one time using current video player software. In order to solve the problem of the synchplayback of multi-channel airborne videos,we propose a synch-playback scheme of multi-channel videos based on C/ S mode. Theserver performs video file read control,and the client performs video decoding and display. Firstly,the basic concept of FFMPEG is introduced. Then the overall design of the system is discussed,and the design and implementation of the server and the client are emphasized. The system is designed in C++ language,and the server uses TCP / IP protocol to interact with the client. The modular and multi-threaded ideas are used in the software design to improve processing efficiency and ensure scalability of function. At present,the software has been successfully applied to synch-playback of multi-channel videos of multiple types’ task. The application shows that the system works steadily and can effectively improve the efficiency of flight test.
