浏览器中通过内嵌swf推rtmp流的javascript库
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 $ php -S 0.0.0.0:8888 访问 http://localhost:8888/demo
$ npm install rtmp-streamer
OR
$ bower install rtmp-streamer
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。
