【libdatachannel】pycharm运行streamer的信令服务及streamer与js客户端联调1-Toy模板网

这篇具有很好参考价值的文章主要介绍了【libdatachannel】pycharm运行streamer的信令服务及streamer与js客户端联调1。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

一信令服务：启动py服务器

ssl必须额外指定

    # Usage: ./server.py [[host:]port] [SSL certificate file]

文档给出了服务的启动命令： python3 -m http.server --bind 127.0.0.1 8080

难道是因为打开了俩客户端推流？

关闭

js客户端没点击stun server，成功

重来

【libdatachannel】pycharm运行streamer的信令服务及streamer与js客户端联调1

这里打印了Client XbVsVWZICw connected 客户端是we端？

没使用stun server反而有数据了
