This script contains antifeatures

Before you install, Greasy Fork would like you to know that this script contains antifeatures, which are things there for the script author's benefit, rather than yours.

Цей скрипт додає рекламу на сайти які ви відвідуєте.

OmniDown – HD Video Downloader (YouTube, TikTok, Instagram, X & More)

Fast, secure, and lightweight userscript to download online videos locally, or redirecting to dedicated external tools when local streams are blocked by CORS/DRM/HLS limits.

Supported Websites & Platforms

  • YouTube: Multiple quality options (Shorts, Embeds, watch videos, audio, subtitles/SRT).
  • TikTok & Douyin: Watermark-free MP4 extraction with fallback options.
  • Instagram: Feed, Reels, Stories, and HLS/Blob streams.
  • X (Twitter): Direct MP4 URLs extractor.
  • Facebook & Threads: Embedded video parsing.
  • Pinterest, Snapchat, TED: Local extraction where possible and site-specific external converters.
  • Spotify: Easy search and download redirects.

Advanced Features

  • Strict Iframe Context Guard: Employs context checking to prevent multi-initialization inside nested ad frames or extensions, restricting global FAB creation to the top-level window.
  • Local-First & Multi-Proxy Download: Downloads videos directly inside your browser whenever possible, utilizing CORS proxies sequentially on network failures.
  • Robust Download Cancellation: Cancels running and queued downloads cleanly, ignoring asynchronous callbacks from aborted connections.
  • Robust JSON Parsing: Uses a bracket-balancing algorithm to extract raw player response variables safely without matching inner strings or nested formats.
  • YouTube base.js Signature Deciphering: Built-in dynamic algorithm decryption for protected streams (including embed and Shorts fallbacks) with automatic redirection fallback recovery when decryption fails.
  • Strict Performance & Execution Scopes: Restricts execution to supported domains only and leverages mutated node batch parsing to eliminate CPU spikes. Backed up with highly relaxed 5-minute idle scan cycles.
  • Native YouTube Player Controls Button: Injects a clean, native SVG download button directly inside YouTube player controls.
  • Clean Memory Management: Maps file sizes and embed configurations inside size-bounded LRU caches to prevent long-term memory leaks.
  • Privacy Confirmations: Never triggers external redirects without explicit user confirmations.
  • Minimized Player & Parallel Downloads: Beautiful, glassmorphic download manager overlay which supports desktop minimization, custom scrollbars, active filename labels, sequential toast queues, and pulsating download indicators.

Controls

  • Floating Button: Appears automatically when a video is loaded on the page (pulses red when downloading).
  • Keyboard Shortcuts:
    • Ctrl + Alt + Shift + D: Open download menu (can be toggled in menu commands).
    • Esc: Close download menu / cancel download.
