Universal Subtitle Translator for Stremio

Universal Subtitle Translator is a Stremio subtitle add-on that:

• translates English subtitle tracks into any supported Microsoft Translator target language
• supports external subtitle add-ons and embedded English subtitle fallback
• exposes the translated result back to Stremio as a selectable subtitle language
• runs locally with no npm dependencies

Features

• Target language selector powered by the official Microsoft Translator supported-languages endpoint
• Custom Subtitle Language Label so you can decide what Stremio shows in the subtitle picker
• Optional source subtitle add-on manifests for external English subtitle fallback
• Optional local-engine embedded subtitle fallback through the Stremio desktop engine
• UTF-8 WebVTT output
• Translation result caching

How It Works

1. Stremio asks this add-on for subtitles for a movie or episode.
2. The add-on looks for English subtitle tracks from any configured subtitle add-ons.
3. If needed, it also tries to detect English embedded subtitle tracks from the local Stremio engine.
4. When you select the generated subtitle language in Stremio, the add-on fetches the original English subtitle text.
5. It sends subtitle cue text to the Microsoft Edge translation endpoint.
6. It returns translated WebVTT subtitles back to Stremio.

Supported Target Languages

The configure page loads the target-language list from the official Microsoft Translator languages endpoint:

• Microsoft Translator supported languages endpoint
• Microsoft Learn Translator reference

This means the add-on can follow the currently available Microsoft Translator language list instead of hardcoding only one target language.

Folder Structure

This universal version lives in:

C:\Users\{YOUR USERNAME}\Documents\idk\stremio-universal-subtitle-translator

The original Kurdish Sorani-specific version is left untouched in the original folder.

Run It

From this folder:

node C:\Users\{YOUR USERNAME}\Documents\idk\stremio-universal-subtitle-translator\src\server.js

The universal clone defaults to:

• Add-on server: http://127.0.0.1:7001
• Configure page: http://127.0.0.1:7001/configure
• Language list route: http://127.0.0.1:7001/languages.json

The port is 7001 by default so it can coexist with the original Sorani-only add-on on 7000.

Configure And Install

1. Start the server.
2. Open http://127.0.0.1:7001/configure.
3. Pick a target translation language.
4. Set the Subtitle Language Label you want Stremio to show.
5. Optionally paste subtitle add-on manifest URLs for external English subtitles.
6. Keep embedded fallback enabled if you want local Stremio engine subtitle extraction.
7. Click Build Manifest URL.
8. Install the generated manifest URL in Stremio.

Configuration Fields

• targetLanguageCode: Microsoft Translator target language code
• displayLanguage: label shown in Stremio
• sourceManifestUrls: external subtitle add-on manifest URLs
• sourceLanguageCodes: which subtitle language labels count as English
• translatorBatchSize: how many subtitle cues to send per translation request
• useLocalStremioProxy: whether to try the local Stremio subtitle conversion proxy first
• enableEmbeddedSubtitles: whether to inspect the local Stremio engine for embedded English subtitle tracks
• stremioEngineUrl: local Stremio engine URL, usually http://127.0.0.1:11470

Notes

• This project is intentionally zero-dependency.
• The translation call uses the Microsoft Edge translation endpoint and may change without notice.
• Embedded subtitle fallback works best for text-based subtitle tracks.
• Image-based subtitle tracks such as PGS or VobSub will not translate cleanly without OCR.
