如何使用韵律将媒体发送到 Jitsi videobridge？

Question

我对 xmpp 和 webrtc 比较陌生。现在，我尝试使用 Jitsi Videobridge 和 prosody 创建简单的视频会议网络应用程序，我不想使用 jitsi-meet，因为我需要知道如何让 jitsi-videobridge 工作。到目前为止，我可以让韵律接受 jitsi-videobridge 组件。所以当我运行./jvb.sh --domain=localhost --port=5347 --secret=componentsecret 时，它会显示这些日志：

JVB 2017-04-21 10:52:53.798 INFO: [38] 
org.jitsi.videobridge.xmpp.ComponentImpl.log() RECV: <iq id="f68D9-340" 
type="result" to="jitsi-videobridge.localhost" from="localhost"/>
JVB 2017-04-21 10:53:03.801 INFO: [40] 
org.jitsi.videobridge.xmpp.ComponentImpl.log() RECV: <iq id="f68D9-341" 
type="result" to="jitsi-videobridge.localhost" from="localhost"/>
JVB 2017-04-21 10:53:13.801 INFO: [42] 
org.jitsi.videobridge.xmpp.ComponentImpl.log() RECV: <iq id="f68D9-342" 
type="result" to="jitsi-videobridge.localhost" from="localhost"/>
JVB 2017-04-21 10:53:23.801 INFO: [44] 
org.jitsi.videobridge.xmpp.ComponentImpl.log() RECV: <iq id="f68D9-343" 
type="result" to="jitsi-videobridge.localhost" from="localhost"/>
JVB 2017-04-21 10:53:33.801 INFO: [46] 
org.jitsi.videobridge.xmpp.ComponentImpl.log() RECV: <iq id="f68D9-344" 
type="result" to="jitsi-videobridge.localhost" from="localhost"/>

我认为这是因为我的 jitsi-videobridge 工作正常（不是吗？）。但现在我不知道下一步该做什么。

那么，如何将我的客户端（我的 Web 客户端使用 strophe.js）连接到 jitsi-videobridge？以及我的客户如何能够将媒体（视频和音频）发送到 jitsi-videobridge。 我已经搜索了一段时间，但找不到任何文档或任何关于如何做到这一点的示例。 p>

有什么帮助或想法吗？ 谢谢。

这种情况不会马上奏效。我们使用 Jicofo 作为焦点，它是实体“对话”到 JVB，然后是用户。这是它的工作原理（我假设你在网络环境中，因为你提到了 strophe.js）：

• 用户通过 XMPP 连接
• 用户加入 MUC
• Jicofo 是管理员并加入每个 MUC
• 另一个用户加入了 MUC
• Jicofo 使用 COLIBRI 协议从 JVB 请求音频/视频通道
• Jicofo 编写一个 Jingle 节并通过 MUC 直接消息将其发送给每个参与者
• 用户获取 Jingle 节并将其转换为 SDP
• 用户可以使用该远程 SDP 设置 WebRTC PeerConnection
• 利润？ :-)
