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.

01
WebRTC 60fps

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
02
Audio Mixing

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
03
Zero-Watermark

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
  • 1-Click instant file download
  • Operates completely offline
Browser-based processing of selected files100% In-Browser Execution: All files, keys, and media streams are processed entirely within local device RAM using HTML5 Canvas, Web Audio, WebAssembly, and native Web Crypto APIs. Zero bytes are uploaded to remote servers.
