之前发布过WebRtc播放rtsp视频流的博客，已经解决了web播放rtsp的问题，但WebRtc太耗内存，且需要命令行启动，对用户不太友好，虽然可以写脚本，让用户一键启动。这是无意间发现的另一种web播放rtsp视频流的办法，个人觉得比WebRtc效果更好，且编码更简洁。

1.EasyMedia下载

EasyMedia: Springboot、netty实现的http-flv、websocket-flv直播点播，支持rtsp、h264、h265、rtmp等多种源，h5纯js播放（不依赖flash），不需要nginx等第三方拉流服务 - Gitee.com

2.使用文档

doc/使用教程（简单例子）.md · MisterZhang/EasyMedia - Gitee.com

建议使用1.2.0的版本，win、mac运行皆正常。

作者在gitee给出的是1.3的下载链接，win、mac运行皆报错。

启动EasyMedia.jar

浏览器运行：localhost:8888，看到下图说明运行成功，此时可以找一个rtsp视频流做测试。

3.前端使用

3.1安装西瓜视频播放插件

package.json中添加依赖

 "xgplayer": "^2.18.2",
 "xgplayer-flv.js": "^2.2.1"

//执行安装命令
npm install

3.2界面中使用

组件
