rtsp2rtmp

功能介绍

  • rtsp转rtmp
  • 大华DSS接口对接
  • 海康调用SDK获取设备通道并拼接rtsp地址

功能详解

rtsp转rtmp
  1. java后台将rtsp流转为rtmp流,并推到nginx上
  2. nginx将数据流以ts文件的形式写到磁盘上,并通过index.m3u8记录
  3. 前端通过nginx访问对应的index.m3u8文件来获取对应的数据流。
大华DSS对接
  1. 登录大华DSS平台
  2. 从大华获取设备信息
  3. 根据设备获取通道、rtsp流、hls流地址
海康对接
  1. 通过海康SDK获取到对应设备的通道数、通道号
  2. 通过通道号拼接rtsp地址
  3. 将rtsp转为rtmp流

            ├── windows-resource windows环境下rtsp转rtmp需要用到的资源

Nginx编译及配置

Linux环境
Windows环境:

相关资源在 resources/windows-resource,相关资源说明如下:

一、Native HLS Playback插件-离线包.rar
    该压缩包是一个Chrome扩展程序,解压后将其添加到Chrome的扩展程序中,就可以直接在Chrome中播放HLS视频流了

二、VLC3x64.rar
    vlc压缩包。开源的跨平台多媒体播放器,可以播放绝大部分多媒体文件,以及 DVD、音频CD、VCD,也支持rtsp、rtmp等多种流媒体协议。
    需要注意的是,如果尝试通过vlc将本地视频文件转RTSP,进行网络串流,然后使用ffmpeg或本项目进行rtsp转rtmp测试,这种做法是不可行的,
    会报错说Could not open input,原因未知。
  
三、nginx 1.7.11.3 Gryphon.rar
    Windows环境下编译好的nginx,里面已经编译好了rtmp模块,解压即可使用

异常说明:

一、加密视频JavaCPP无法停止转流
   1. 异常描述:通过海康的SDK获取到了海康NVR上面所有的通道,且RTSP地址拼接无误,设备、网络等一切正常。
                根据获取到的RTSP地址创建好转流任务后,没有任何视频画面播出,一直404。发现nginx配置的路径下没有创建对应的文件夹及m3u8、ts文件,
                nginx日志除了访问的地址404以外没有任何其他异常信息输出,JavaCPP日志一直输出如下信息:

                即使在转流任务被清除后,该JavaCPP线程依旧在疯狂运行,占用了大量系统资源,没办法只能重启程序才能彻底结束这些线程。
   2. 解决办法:经过排除、对比后发现,这个NVR启用了萤石云的加密,在后台关闭加密后,就能够正常转流、播放了。
   3. 遗留问题:想不通为什么转流任务被清除后,对应的JavaCPP线程依旧在疯狂运行,后续去bytedeco提个issue问问看
