安装：我通过npm使用medialementjs（v4.2），安装作为文档中提到的React组件的一部分完成。它运行在KAIOS 2.5上，我认为它的行为应类似于Firefox 48.0。 我遇到的问题是，我看到很多呼叫都失败，并显示HTTP状态代码416。深入研究失败的呼叫后，我发现这些呼叫的字节范围大于音频的内容长度（根据先前的HTTP请求确定）文件。我找不到发生这种情况的任何原因。
添加416方案的请求/响应详细信息，主机和文件名将替换为虚拟变量：

播放网址的代码：
mediaelementJsInstance.setSrc(src);
//mediaelementJsInstance.load(); // I have tried both with and without load and it does not have an effect.
mediaelementJsInstance.play();
我的问题是：
a）我如何播放src或中介元素设置
b）我应该使用相同的CDN来查看CDN，而其他客户端（android / ios）不会遇到相同的问题
