介绍：
+
1. 支持ws-flv, http-flv, hls, webrtc
+
2. WebRTC使用方式：webrtc://xxx
+
3. 使用时出现跨域请下载文件到本地调试
+
4. 当浏览器不支持 MSE硬解 时，会自动切换成 WASM软解
+
5. 关闭音频渲染可以节省性能
+
6. 支持 电子放大;
+
7. 支持 水印(动态水印、幽灵水印);
+
8. 支持 显示上一个视频最后一帧;
+
9. 支持 播放器快照截图;
+
10.支持 视频录制(WebM格式(音频+视频)、MP4格式(视频),FLV格式(音频+视频));
+
11.支持 超时、断网重连、异常暂停播放等;
+
