🇺🇸 User Manual

1. Prerequisites

  • Browser: Highly recommended to use Chrome, Edge, or other Chromium-based browsers (Brave, etc.).
    • Note: The script uses the FileSystemAccess API for stream recording, which may not be fully supported in Firefox.
  • Extension: Tampermonkey is required.
  • Network: Ensure you have access to the video hosting site.

2. Installation

  1. Click the Tampermonkey icon in your browser toolbar and select "Create a new script...".
  2. Delete all default code in the editor.
  3. Copy and paste the full V8 code into the editor.
  4. Press Ctrl + S or click "File" -> "Save".

3. How to Use

  1. Visit Site: Go to a website containing M3U8 or MP4 videos.
  2. Play Video: You must start playback. The script works by intercepting network traffic; if the video doesn't load, the script cannot detect it.
  3. Check the Panel:
    • A floating panel will appear in the top-right corner.
    • Green Border: Video detected in the main window (Top frame).
    • Pink Border: Video detected inside an Iframe (embedded player).
  4. Actions:
    • Copy: Copies the stream URL to your clipboard (useful for external downloaders like IDM).
    • Download:
      • Opens a "Save As" dialog.
      • The script downloads M3U8 segments, transmuxes them to MP4 using mux.js locally, and streams the data directly to your hard drive.
      • Benefit: Low memory usage, supports large files.

4. Troubleshooting (FAQ)

  • Q: Why does nothing happen when I click Download?
    • A: Ensure you are using Chrome/Edge version 86+. If the browser lacks File System API support, the script will show an alert.
  • Q: Connection errors or CORS issues?
    • A: The script uses GM_xmlhttpRequest to bypass CORS. When running for the first time, Tampermonkey may ask for permission to access cross-origin domains. Please select "Always Allow".
  • Q: Can it download encrypted videos?
    • A: It supports standard HLS encryption (AES-128) if the key is accessible. It cannot download DRM-protected content (Widevine/PlayReady).
  • Q: The panel blocks the view.
    • A: Drag the panel by its header to move it. Click the − button in the top corner to minimize it.
