Jitsi视频桥参与者失去连接

我有一个相当库存的安装与认证。该装置仅用于1到多个广播。一个人分享他们的屏幕，每个人开始静音和隐藏，跟随那一个人

我有一个自适应的last n=true，通道last n=1

几分钟后，屏幕共享开始失败。参与者的屏幕变为灰色。广播用户在屏幕共享中的上传速度约为500kbps，但每个人的下载速度均为11kbps或N/a

我偶尔在jvb日志中看到这一点

我在videobridge sip属性中设置org.jitsi.videobridge.ratecontrol.VideoChannelLastNAdaptor.MAX_STAY_AT_ZERO_MS=5000，以强制在5秒后重试

在冻结的参与者中检查chrome的控制台日志显示：

Logger.js:125[JitsiMeetJS.js]：未处理错误：null脚本：null行：null列：null StackTrace:Error:Ping超时在strophe.Ping.js:102在u.TimedHandler.handler（strophe.js:2752）在u.TimedHandler.run（strophe.js:2095）在u.Connection.\u onIdle（strophe.js:3706）r@Logger.js:125

这类会议的最佳配置是什么（screenshare 1发送到多个接收）

老实说，我不知道为什么有些人的视频会掉下来，无法重新连接。有人能帮忙吗？

你有多少观众？请注意，adaptive last N已经消失（作为一个选项），它现在一直都是这样

您可以尝试使用meet.jit.si并设置每个人都开始静音并被主持人隐藏，以检查这不是基础设施问题。或者，此场景是YouTube广播的完美场景：您可以让广播者加入会议室并将其传输到YouTube，在那里所有观众都可以观看直播
