jellyfin-transubtitle

This is a Python script that performs automatic translation of subtitles in the ASS format for media items in a Jellyfin media server. It uses the Baidu Text Translation API for translation purposes.

How To Use

1. Install Docker (Compose)
2. Edit the .env file. (Copy from .env.example)
3. Execute docker-compose up (If as daemon, Add the -d option.)

Parameter Description

The following are the parameters that can be defined and their purposes:

• USER_NAME: The username of the Jellyfin user for whom the subtitles will be translated.
• BASE_URI: The base URL of the Jellyfin server.
• API_TOKEN: The API token for accessing the Jellyfin server.
• JELLYFIN_TARGET_LANG: The target language for the translated subtitles.
• SCAN_INTERVAL: The interval (in seconds) at which the script scans for new media items.

Ensure that the environment variables are correctly set before running the script.

Baidu Text Translation API

The script utilizes the Baidu Text Translation API. That requires the following Baidu API credentials to be set as environment variables:

• BAIDU_APP_ID: The App ID for the Baidu Text Translation API.
• BAIDU_APP_KEY: The App Key for the Baidu Text Translation API.
• BAIDU_TARGET_LANG: The target language for translation using the Baidu Text Translation API.

Other Notes

The script performs the following tasks:

1. Loads the user information from the Jellyfin server using the jellyfin('Users') function and extracts the user ID based on the provided username.
2. Defines a scan function that recursively scans the media library of the user and calls a provided callback function for each media item.
3. Defines a translate_ass function that translates the content of an ASS subtitle file using the Baidu Text Translation API.
4. Defines a translate_subtitle function that checks if a media item has ASS format subtitles and translates them if the target language is not already available.
5. Enters a loop that continuously scans for new media items and translates their subtitles using the scan and translate_subtitle functions.
6. The loop is interrupted by a keyboard interrupt (Ctrl+C) to gracefully stop the script.
