我有一个带有身份验证的漂亮库存安装。该装置仅用于一对多广播。1 人共享他们的屏幕，每个人都开始静音和隐藏，关注该 1 人。

我有自适应最后 n = true，通道最后 n = 1。

几分钟后，屏幕共享开始失败。参与者的屏幕变灰。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为 11kbps 或 N/A。

我在 jvb 日志中间歇性地看到这个

我org.jitsi.videobridge.ratecontrol.VideoChannelLastNAdaptor.MAX_STAY_AT_ZERO_MS=5000在 videobridge sip-properties 中设置强制在 5 秒后重试。

检查冻结参与者中的 chrome 的控制台日志显示：Logger.js:125 [JitsiMeetJS.js] <Object.getGlobalOnErrorHandler>: UnhandledError: null Script: null Line: null Column: null StackTrace: Error: Ping timeout at strophe.ping.js:102 at u.TimedHandler.handler (strophe.js:2752) at u.TimedHandler.run (strophe.js:2095) at u.Connection._onIdle (strophe.js:3706) r @ Logger.js:125

这种会议的最佳配置是什么（屏幕共享 1 发送到多个接收）？

老实说，我不确定为什么某些人的视频会掉线并且不会重新连接。任何人都可以伸出援助之手吗？

你有多少观众？请注意，自适应最后 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被主持人静音和隐藏，以检查这不是基础设施问题。或者，这种场景非常适合 YouTube 广播：您可以让广播员加入房间并将其流式传输到 YouTube，所有观众都可以在其中观看直播。

您还可以通过更改 Jicofo 中的代码将用户设置为在会议开始时静音（并阻止音频和视频传输）（除了正在演示的主持人）。这是永久禁止用户发送视频或音频的方法名称：
