【摘要】：随着无线网络及流媒体在技术基础、传输速率等方面的飞速发展,智能终端在性能、配置上不断提高,越来越多的人通过智能手机等移动终端随时随地的接入互联网来获取自己想要的信息,传统的基础性移动服务业务已无法满足人们的需求,以文字、图片、音频和视频为主的移动多媒体业务正在迅猛的发展,也必将成为移动互联网的发展趋势。本文针对目前最流行的IOS平台,设计了一套实时视频监控的客户端软件,针对]OS平台客户端软件的应用界面、操作方式以及业务逻辑,设计了用户登录注册功能、视频端子多种方式的展示功能、实时视频观看功能、信息推送功能、录像以及录像播放功能、截屏以及查看截屏功能、根据当前位置来查看感兴趣视频端子的功能等,其中我们重点研究IOS平台下移动流媒体数据的接收、解码、丢包处理、播放、录制视频等功能,提出采用H.264编码和RTSP协议对视频的封装发送,在保持监控系统特点的前提下,使得编解码过程在达到监控系统的要求下做到最简与最优,同时对FFmpeg开源框架进行研究,优化该框架的解码部分,最终实现IOS平台上的实时解码工作。
[Abstract]:With the rapid development of wireless network and streaming media in technology foundation, transmission rate and so on, intelligent terminals are improving their performance and configuration. More and more people are accessing the Internet anytime and anywhere through mobile terminals such as smart phones to get the information they want. The traditional basic mobile services can no longer meet the needs of people, with text and pictures. Audio and video-based mobile multimedia services are developing rapidly and will certainly become the trend of mobile Internet. Aiming at the most popular IOS platform at present, this paper designs a set of client software for real-time video surveillance, aiming at the application interface, operation mode and business logic of client software of OS platform, and designs the function of user login and registration. Video terminal display function in many ways, real-time video viewing function, information push function, video recording and video playback function, screen capture and view screen capture function, viewing the function of interested video terminal according to the current position, etc. Among them, we focus on the functions of receiving, decoding, packet loss processing, playing and recording video of mobile streaming media data on IOS platform. We propose to use H.264 encoding and RTSP protocol to encapsulate and send video, while keeping the characteristics of monitoring system. At the same time, the FFmpeg open source framework is studied, the decoding part of the framework is optimized, and the real-time decoding work on IOS platform is finally realized.
