在尝试使用webRTC实现webapp直播失败后,转移思路开始另外寻找可行的解决方案。在网页上尝试使用webRTC实现视频的直播与看直播,在谷歌浏览器以及safari浏览器上测试是可行的。但是基于基座打包为webapp后不行,所以直播的话建议还是原生的好。HBuilder自带的H5+有提供了原生的视频播放和推流录制上传,但是需要有一个rtmp直播流服务器,用于测试和开发,这时就需要自建rtmp服务推流了。
极速搭建简单RTMP直播流服务器
开发环境:macOS
需要安装并启动docker:?? Docker Community Edition for Mac
- $ docker --version
- Docker version 18.06.1-ce, build e68fc7a
- $ docker-compose --version
- docker-compose version 1.22.0, build f46880f
- $ docker-machine --version
- docker-machine version 0.15.0, build b48dc28d
如果是自己使用nginx搭建rtmp直播服务器,毕竟是接触这个不到半天,还是有点复杂,编译设置有点繁琐。好在docker上有大把别人编译设置好的rtmp环境,所以先拿来玩着先,有空还是自己要来搞搞的。这里用到的是alfg/nginx-rtmp库。
- Pull docker image and run:
- docker pull alfg/nginx-rtmp
- docker run -it -p 1935:1935 -p 8080:80 --rm alfg/nginx-rtmp
- Build and run container from source:
- docker build -t nginx-rtmp .
- docker run -it -p 1935:1935 -p 8080:80 --rm nginx-rtmp
直播推流地址
- rtmp://<server ip>:1935/stream/$STREAM_NAME
播流地址
- http://<server ip>:8080/live/$STREAM_NAME.m3u8
使用OBS测试rtmp直播流服务器
下载安装 OBS,在随便网上找一条视频在obs无限循环播放。obs=>设置=>流

开始推流
safari浏览器测试效果

RTMP直播流服务器简单搭建成功,这个只是简单的实现了 推流播流而已,测试发现直播有延迟大概10s左右。还需要调配像素以及贞。或者说使用成熟的第三方的推流地址与播流地址。
