android - LAN 上的 Android WebRTC：仅将候选 127.0.0.1 发送到信令服务器

Question

我正在尝试创建一个基于 WebRTC 的 Android 视频聊天应用程序，以部署在本地网络上。设置很简单：2 个 Android 终端和一个 Linux 服务器在同一个本地网络（以太网）上。没有 STUN 也没有 TURN 服务器。只有主机候选者和一个信令服务器（HTTP+WS）。

• 几年前，我在 GitHub 上发现了一个基于 libjingle-9127的 Android 应用程序，以及相关的 Node.js 服务器。我的设置开箱即用。

• 这个库已有 4 年历史，我尝试迁移到最新的 google-webrtc Android SDK + appr.tc 服务器的 Node.js 端口。信号效果很好，但视频聊天本身失败了。

尝试比较两个版本，我意识到发送到信令服务器的候选列表是：

• 每个带有 libjingle 版本的网络接口一个候选者
• google-webrtc 版本只有 127.0.0.1 和 :::1

这似乎是由于中间引入了一种称为Trickle ICE的 WebRTC 机制。而且我不知道如何配置 WebRTC 来声明与我的本地网络接口相对应的候选人。

是否有 WebRTC Android SDK 的 API 可以让我这样做？

谢谢！

PS：发送到信令服务器的候选列表。

使用 libjingle-9127
