## Description

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:
<ul><li><strong>Master Playlist Detection:</strong> Automatically identifies the main M3U8 manifest file, not just the lower-quality segments.</li><li><strong>Subtitle Catching:</strong> Finds and lists all VTT, SRT, or other text-based subtitle files associated with the video stream.</li><li><strong>Intelligent Metadata:</strong> Displays the highest available resolution and video/audio codecs directly in the popup, so you know exactly what you're getting.</li><li><strong>One-Click Command:</strong> 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.</li><li><strong>User Control:</strong> A comprehensive options page allows you to either allow all sites by default or create a specific whitelist for targeted use.</li></ul>

IMPORTANT: How to Use for Video Downloads

StreamCatch is a <strong>link-finding utility</strong>, not a standalone downloader. It is designed to work hand-in-hand with powerful, open-source command-line tools.
<ol><li><strong>Install yt-dlp:</strong> You must have yt-dlp installed on your computer. Follow the official installation instructions on their GitHub page.</li><li><strong>Install FFmpeg:</strong> 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.</li><li><strong>Use the "Copy Command" Button:</strong> When StreamCatch detects a video, click the "Copy Command" button in the popup.</li><li><strong>Paste and Run:</strong> Paste the command into your Terminal (macOS/Linux) or Command Prompt/PowerShell (Windows) and press Enter. yt-dlp will handle the rest!</li></ol>
