Go2RTC Play — Android WebView Multi-Camera Viewer

An Android app that displays multiple IP camera streams from a go2rtc server in a grid layout inside a WebView.

Features

• Grid view — all cameras visible simultaneously, auto-relayout on hide/show
• MJPEG frame polling — codec-independent; shows H.264, H.265, and MJPEG cameras
• Persistent camera list — remembers working cameras across restarts
• Fullscreen playback — WebView with go2rtc's adaptive streaming (WebRTC/MSE/HLS)
• LAN auto-discovery — scans subnet for go2rtc servers
• D-pad navigation — works with Android TV remotes
• Auto-hide UI — top bar fades after 3 seconds

How it works

1. App connects to a go2rtc server (port 1984)
2. Fetches camera list via /api/streams
3. Renders a CSS Grid inside a WebView
4. Each camera polls /api/frame.jpeg?src=name every 5 seconds
5. Clicking a camera opens FullscreenActivity with stream.html?src=name&mode=...
