我有一个很好的库存安装和身份验证。该安装仅用于1对多广播。 1人分享他们的屏幕，每个人都开始静音＆amp;隐藏，跟着那个人。
我有自适应最后n =真，通道最后n = 1.
几分钟后屏幕开始失败。参与者的屏幕变灰。广播用户在屏幕共享中上传了500kbps，但每个人都有11kbps或N / A的下载。
我间歇地在jvb日志中看到这个

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

此类型会议的最佳配置是什么（屏幕共享1发送给多次接收）？
老实说，我不确定为什么视频会丢失给某些人而且没有重新连接。任何人都可以伸出援助之手吗？
答案 0 :(得分：0)
你有多少观众？请注意，自适应最后N消失了（作为一个选项），它现在一直都是那样。
您可以尝试使用meet.jit.si并设置每个人都开始静音并由主持人隐藏，只是为了检查它不是基础设施问题。或者，这种情况对于YouTube广播来说是完美的：您可以让广播公司加入会议室并将其流式传输到YouTube，所有观众都可以在这里观看。
