| 摘 要： | 为了在iOS平台上实现对特定场景的实时音视频监控,设计并实现了基于iOS的音视频监测软件。软件采用SIP(会话初始化协议)作为信令控制协议,采用RTP(实时传输协议)实现音视频数据传输,利用FFmpeg和iOS固有的音视频处理框架实现音视频的解码播放。由于无线传输网络的不稳定性和音视频编解码消耗时间的不同导致了音视频数据的不同步,因此软件采用基于RTP协议的音视频同步控制方法。

| Abstract: | In order to achieve the real time audio -video surveillance of a specific scene on iOS platform, an audio -video monitoring software based on iOS is designed and implemented. The software uses SIP（ Session Initiation Protocol）as the sig- naling control protocol, using the RTP （ Real - time Transport Protocol ） achieve audio and video data transmission. Using FFmpeg and audio - video processing framework inherent in iOS to decode audio and video. The transmission of wireless net- works is not stable and the different time - consuming of audio and video codec leads to out - sync of audio and video. There- fore, a control method of audio - video synchronization based on RTP is adopted. |
