Streamcatch

[NEW in v5.2]

► Smart Subtitle Extraction: Now automatically detects nested HLS subtitle playlists (#EXTM3U) and downloads the actual VTT/SRT segments.

► Bug Fixes: Resolved issues with manifest parsing on specific streaming 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, ensuring you get the master stream rather than just lower-quality segments.

► Enhanced Subtitle Catching: Finds and lists all VTT, SRT, and segmented HLS subtitle playlists. It parses nested manifests to extract the actual file links, even when hidden in JSON files or complex playlist structures.

► Intelligent Metadata: Displays the highest available resolution and video/audio codecs directly in the popup, so you know exactly what quality you are capturing.

► 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.

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.

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!
