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 正常工作。到现在为止，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 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]

JVB 2017-04-21 10:53:23.801 INFO: [44]

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"/>

我认为我的 jitsi-videobridge 工作正常（不是吗？）。但是现在我不知道下一步该怎么做。

那么，如何将我的客户端（我使用 strophe.js 作为网络客户端）连接到 jitsi-videobridge？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，但我找不到任何文档或任何关于如何做到这一点的示例.

这是我的韵律 prosody.cfg.lua:

Include "conf.d/*.cfg.lua"

这是我的 sip-communicator.properties:

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"talking"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 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 编写了一个 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？ :-)

希望对您有所帮助。免责声明：我在 Jitsi 工作。
