AC3 Video Converter

This is a tool for automatically converting your media library to AC3 or EAC3 audio codec. It uses FFMPEG to convert the files. The AC3 codec stands for Dolby Digital and the EAC3 codec stands for Dolby Digital Plus.

Features

  • Convert AAC to AC3
  • Convert DTS, DTS-HD, OPUS and HE-AAC to EAC3
  • Converts all audio tracks in the file
  • Keeps all subtitles
  • Add multiple library paths (see below)
  • Telegram notifications

Installation

docker run -d \
--name ac3-converter \
-v /path/to/tvshows:/library/tvshows \
-v /path/to/movies:/library/movies \
-e libraries="/library/tvshows;/library/movies" \
--restart unless-stopped \
--user ${id -u}:${id -g} \
rutgernijhuis/ac3-video-converter

In the above command there are two libraries mounted. On the host the library /path/to/tvshows/ is the location where the media lives, this is mapped to /library/tvshows in the container. You can add as many libraries as you want, but you need to specify the mapped paths in the environment variable libraries delimitted by a semicolon: (;) as shown.

Environment variables

Variable Required Default Usage
libraries Yes "" Specify all mapped library paths delimited by a semicolon
interval No 3600 Scan interval in seconds
replace_original No true Should the original file be replaced? Mostly used for testing
telegram_token No "" Telegram bot token
telegram_chat_id No "" Telegram chat id

Running it locally

If you want to run it locally, I suppose you know what you are doing.

Prerequisites

  • Python 3
  • FFMPEG (also in your path)

Tested on Python 3.8.5

pip install -r requirements.txt

Note Before running:

The script uses environment variables to locate your library, interval time and other settings. Make sure the script can find them. For testing purposes it is reccomended to use ./demo_libraries/movies;./demo_libraries/shows as value for libraries with your own content.

I used VSCode for developing and added them to ./vscode/launch.json
