Remote Preview Control Plane

SO API Base URL: https://service.kt-api.com

Device Streams:

device_7ca1fa03-2797-4ce5-b95a-6321fbbcdcab state=lease_expired desiredLive=true lease=2026-07-10T14:07:42.358Z currentSessionId=rp_mreyropo_8og4kn stable viewer

登录账号: demo / 3dP2ROQjmy1ST8V9UXoE（登录现在不是远程预览前置条件）

当前控制面已同时提供 auth、device session、commands、state/heartbeat、offer/answer 和 viewer 页面。

使用步骤

在软件里把 SO API Base URL 改成 https://service.kt-api.com
保持软件打开；远程预览会先用稳定 deviceId 换取本次启动的临时 deviceToken
等待客户端轮询到 start_preview
打开下面生成的 viewer 链接看画面

当前会话

rp_mreyropo_8og4kn [active] deviceId=device_7ca1fa03-2797-4ce5-b95a-6321fbbcdcab state=lease_expired lease=2026-07-10T14:07:42.358Z stream=lease_expired desiredLive=true stable viewer session viewer

说明：[active] 才是当前设备真正会继续收命令的会话；点击 stop + new 会立即切到新 session，[stale] 只是历史记录。
