StreamCatch

Catches M3U8 manifest and subtitle links (VTT, SRT) from network requests on user-allowed sites.

StreamCatch is a powerful and lightweight browser extension for developers, power-users, and media enthusiasts who need to locate and capture streaming media links from the web. Have you ever needed to analyze a video stream, debug a media player, or simply save a master playlist for offline use with a tool like yt-dlp? StreamCatch simplifies this process by observing the network traffic of a webpage and intelligently identifying the master playlist (.m3u8) and any associated subtitle files (.vtt, .srt). It's a simple, focused tool designed to do one thing perfectly. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ KEY FEATURES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ► Master Playlist Detection: Automatically identifies the main M3U8 manifest file, not just the lower-quality segments. ► Subtitle Catching: Finds and lists all VTT, SRT, or other text-based subtitle files associated with the video stream, including those hidden in JSON files. ► Intelligent Metadata: Displays the highest available resolution and video/audio codecs directly in the popup, so you know exactly what you're getting. ► One-Click Command: Generates a clean, ready-to-use yt-dlp command with the correct referer and a sanitized filename, copied to your clipboard in a single click. ► User Control: A comprehensive options page allows you to either allow all sites by default or create a specific whitelist for targeted use. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ IMPORTANT: HOW TO USE ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ StreamCatch is a ► LINK-FINDING UTILITY ◄, not a standalone downloader. It is designed to work hand-in-hand with powerful, open-source command-line tools. 1. Install yt-dlp: You must have yt-dlp installed on your computer. Follow the official installation instructions on their GitHub page. 2. Install FFmpeg: yt-dlp requires the free FFmpeg tool to merge the video and audio streams into a final MP4 file. Make sure FFmpeg is installed and accessible in your system's PATH. 3. Use the "Copy Command" Button: When StreamCatch detects a video, click the "Copy Command" button in the popup. 4. Paste and Run: Paste the command into your Terminal (macOS/Linux) or Command Prompt/PowerShell (Windows) and press Enter. yt-dlp will handle the rest!
