## Introduction

This program helps to change audio and subtitle tracks of mkv files without rewriting the file. Only track properties will be updated.

## Requirements

 - Java 11 or higher
 - mkvtoolnix installation
 
## Execution
**Minimal usage:**
`java -jar mkvaudiosubtitlechanger.jar --library "X:/Files" --attribute-config eng:ger eng:OFF`

**Safe usage (best for testing before applying to whole library):**
`java -jar mkvaudiosubtitlechanger.jar --library "X:/Files" --attribute-config eng:ger eng:OFF --safe-mode`

Attribute-config must be entered in pairs: `audio:subtitle`; Example: `jpn:eng`. More about this topic
[here](https://github.com/RatzzFatzz/MKVAudioSubtitleChanger/wiki/Attribute-Config).
