PearPlayer发布后，引起各方关注，但是有较强开发能力的CP集成起来困难，因为已经有的开发数年的H5播放器了。为此， 我们将多源传输部分抽离出来，形成PearDownloader。这样各家CP可以根据需要集成到产品/项目中， 例如，视频厂商可以将PearDownloader集成到已有播放器中，采用我们的算法或自己设计算法，将从多源多协议取得的数据喂给播放器。 PearDownloader（梨享下载器） 是PearPlayer的底层下载模块， 实现了融合HTTP（包含HTTPS、HTTP2）、WebRTC的多协议、多源、低延迟、高带宽利用率的无插件Web端下载加速能力。 基于高效的调度算法将来自多个节点的数据进行拼接形成完整的文件或将有序的数据/媒体流喂给上层的应用，例如音视频播放器， PearDownloader能在保证下载速度前提下最大化P2P率。
只需将pear-downloader.min.js通过<script>标签导入到HTML就可以使用。
参考以下代码示例，也可以查看/examples/downloader-test.html来了解使用方法。
参考get-started来了解基本使用方法。
Demo演示地址：https://demo.webrtc.win/peardownloader/
首先通过script标签导入pear-downloader.min.js：
<script src="./dist/pear-downloader.min.js"></script>
或者使用CDN：
<script src="https://cdn.jsdelivr.net/npm/peardownloader@latest/dist/pear-downloader.min.js"></script>
假设要下载https://qq.webrtc.win/tv/Pear-Demo-Yosemite_National_Park.mp4
<script>
/**
* 第一个参数为文件的url
* opts是可选的参数配置
*/
var downloader = new PearDownloader('https://qq.webrtc.win/tv/Pear-Demo-Yosemite_National_Park.mp4', opts);
</script>
恭喜您，您的下载器已经具备P2P能力了，而且无须任何插件！
