Arabic Auto-Sync Subtitles v2.0

Overview

Automatic Arabic subtitle synchronization for Stremio. Fetches Arabic subtitles from three sources simultaneously and auto-syncs them using a trusted English reference.

Key Features

• Triple Source Aggregation: OpenSubtitles v3, SubDL, SubSource — all fetched in parallel
• Auto-Sync Engine: Pure JavaScript reference-based alignment (no external tools needed)
• Smart Caching: 6-hour cache for synced results — instant on repeat requests
• Arabic Text Normalization: Removes diacritics, fixes encoding issues (Windows-1256, UTF-8)
• Anti-Timeout Strategy: Returns placeholder while processing in background
• Labeled Subtitles: Each subtitle shows its source e.g. [Synced] SubDL - Arabic

How to Install

1. Open Stremio
2. Go to Add-ons -> Install from URL
3. Paste: https://7000-i5qiinvaxas86mhpc6fn7-1ee50674.sg1.manus.computer/manifest.json

How It Works

1. You select a movie or TV show in Stremio
2. The addon fetches Arabic subtitles from OpenSubtitles, SubDL, and SubSource simultaneously
3. It also fetches the top English subtitle as a timing reference
4. Using linear regression alignment, it syncs the Arabic subtitle to match the English timing
5. Results are cached for 6 hours for instant future requests
