Replace time.Now() calls in hot path with frame-based timing: - Pre-compute triggerLevel (integer comparison instead of float division) - Calibrate hold/cooldown budgets from FPS (default 30fps) - Periodic FPS recalibration every 150 frames for accuracy - Active motion path: 47ns → 3.6ns (13x faster) Update schema.json with detect mode and motion_threshold. Add threshold tuning guide to README.

This folder contains static HTTP and JS content that is embedded into the application during build. An external developer can use it as a basis for integrating go2rtc into their project or for developing a custom web interface for go2rtc.
HTTP API
www/stream.html - universal viewer with support params in URL:
- multiple streams on page
src=camera1&src=camera2... - stream technology autoselection
mode=webrtc,webrtc/tcp,mse,hls,mp4,mjpeg - stream technology comparison
src=camera1&mode=webrtc&mode=mse&mode=mp4 - player width setting in pixels
width=320pxor percentswidth=50%
www/webrtc.html - WebRTC viewer with support two way audio and params in URL:
media=video+audio- simple viewermedia=video+audio+microphone- two way audio from cameramedia=camera+microphone- stream from browsermedia=display+speaker- stream from desktop
JavaScript API
- You can write your viewer from the scratch
- You can extend the built-in viewer -
www/video-rtc.js - Check example -
www/video-stream.js - Check example - https://github.com/AlexxIT/WebRTC
video-rtc.js features:
- support technologies:
- WebRTC over UDP or TCP
- MSE or HLS or MP4 or MJPEG over WebSocket
- automatic selection best technology according on:
- codecs inside your stream
- current browser capabilities
- current network configuration
- automatic stop stream while browser or page not active
- automatic stop stream while player not inside page viewport
- automatic reconnection
Technology selection based on priorities:
- Video and Audio better than just Video
- H265 better than H264
- WebRTC better than MSE, than HLS, than MJPEG
Browser support
ECMAScript 2019 (ES10) supported by iOS 12 (iPhone 5S, iPad Air, iPad Mini 2, etc.).
But ECMAScript 2017 (ES8) almost fine (es6 + async) and recommended for React+TypeScript.
