| 摘 要： | 文中讨论了在基于纯软件的网络视频会议中录播技术的实现方案,方案应用多线程写技术,将经压缩传输后的每一个视音频数据包分别写入时间戳,然后同步录制成视频文件和音频文件。播放时先解压缩,然后根据写入的时间戳和线程同步技术进行视、音频自适应同步播放。由于播放器集成在系统中,有利于会议信息保密。本方案已成功应用于交通部网络视频会议系统。

| Abstract: | In this paper, the scheme to implement the functions of recording and playing in the software video conference system is discussed. Based on the technologies of multi-thread and the binary file reading and writing, the compressed video and audio data companied with the time makers are stored separately into a video file and an audio file. By the time marker written in the file, the encoded video and audio data can be played in synchronization under control. As the playing part is integrated in the system, it is advantageous to keep secret for the conference information. The scheme has implemented successfully in the system of the network video conference for the ministry of communications. |
