Abstract
In the flight test, the airborne video data is an important part of the flight test data. At present, the airborne recorded video data is an independent M2T file, and the existing video playback software can only play back a single video file. In order to solve the problem of synchronous playback of airborne multi-channel video data, a multi-channel video synchronous playback technology based on C/S mode is proposed. The server performs video file reading 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. The design and implementation of the server and the client are emphasized. The system is designed with C++ language, and the TCP/IP protocol is used in the server to interact with the client. Software design uses modularity and multi-threaded to improve processing efficiency and ensure functional scalability. At present, the software has been successfully applied to the simultaneous playback of multiple types of missions and multiple channels of video. The actual application results show that the system is stable and can effectively improve the efficiency of model flight tests.
