rtmp-streamer

浏览器中通过内嵌swf推rtmp流的javascript库

Demo

可在任何http容器中加载项目目录来运行demo

如 http-server:

 $ http-server -p 8888 

或 PHP build-in web server:

 $ php -S 0.0.0.0:8888 

访问 http://localhost:8888/demo

Install

 $ npm install rtmp-streamer

OR

 $ bower install rtmp-streamer

Tutorial

rtmp-streamer 遵循AMD规范，可通过require.js等方式加载, 另外, 请确保在页面中引入了RtmpStreamer.swf, 否则rtmp-streamer将无法正确载入。

采用直播云服务

以七牛云为例:

设置参数的方式和用OBS等工具推流时的方式类似, 地址为直播云的空间名, 数据流名称为直播流的名称加鉴权参数:
