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:

``bash
$ http-server -p 8888
`

或 PHP build-in web server:

`bash
$ 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。

`html

`

`javascript
require(["rtmp-streamer"], function (RtmpStreamer) {
var streamer = new RtmpStreamer(document.getElementById('rtmp-streamer'));
streamer.publish(url, name);
});

#### 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:
