🌟 English Overview

StudyFlow is an open-source, zero-cost Google Chrome extension (Manifest V3) designed to give learners full control over online lecture videos. It breaks standard browser playback limitations by providing smooth speed scaling up to 16x, preventing annoying pause triggers when you switch browser tabs (Anti-Pause), and automating lecture progression across online course platforms.

🎯 Key Engineering Capabilities

1. 🚀 Unrestricted Hardware-Accelerated Playback Speed:

   • Overrides default player speed limits (1x, 1.5x, 2x) with custom rates up to 16x.
   • Preserves smooth rendering using HTML5 HTMLMediaElement.prototype synchronization.

2. 🔒 Background Anti-Pause (Visibility Hooking):

   • Intercepts document.visibilitychange, document.hidden, and window.blur events via MAIN world script injection.
   • Videos keep playing smoothly even when minimized or running in a background tab.

3. 🔄 Cross-Frame / Iframe Audio-Video Synchronization:

   • Uses bidirectional window.postMessage communication to bridge nested iframe players (such as Cinema8, Vimeo, and custom embedded players) with the top-level parent window.

4. 🔇 Adaptive Auto-Mute:

   • Automatically silences audio on extreme playback rates (e.g. > 3x) to avoid distortion and harsh audio spikes.

5. 📌 Non-Intrusive Floating HUD:

   • Optional lightweight draggable on-screen controller overlay directly on the video player for instant speed toggles.
