WebRTC MediaStream Capture & MediaRecorder Video Architecture
Learn how ToolsHub captures desktop display buffers, mixes stereo microphone channels, and writes WebM video containers in client RAM.
Hardware WebRTC DisplayMedia Pipeline
Directly accesses desktop compositors via `navigator.mediaDevices.getDisplayMedia`, acquiring 60 FPS raw video frames without third-party extension plugins.
- Captures full screen, window, or browser tab
- Ultra-low CPU usage with hardware encoding
- Video buffers never leave local device memory
Stereo Audio Context Mixing Matrix
Leverages the Web Audio API (`AudioContext`) to mix system sound with live microphone speech input into a single synchronized audio stream.
- Clear voiceover speech recording
- Prevents audio desynchronization drifts
- Includes live mute toggle controls
Zero-Watermark Client-Side Export
Streams encoded video chunks into a local browser Blob, creating immediate high-definition `.webm` video files ready for Slack, YouTube, or bug reports.
- No paywalls, branding, or time limits
