# dvdsubconvert

A command-line tool built with Deno to extract, convert, and remux DVD subtitles
from MKV video files into SRT format, then combine them back into a new MKV
file.

## Prerequisites

Ensure the following tools are installed and available in your PATH:

- [MKVToolNix](https://mkvtoolnix.download/) (provides `mkvmerge` and
  `mkvextract`)
- [FFmpeg](https://ffmpeg.org/)
- [vobsub2srt](https://github.com/ruediger/VobSub2SRT) (for converting VobSub
  subtitles to SRT)

## Installation

Clone the repository and ensure Deno is installed
([Deno installation guide](https://deno.land/manual/getting_started/installation)).

## Usage

Run the tool with a single MKV file as input:

```bash
deno run --allow-run --allow-write --allow-read src/main.ts input.mkv
```

The tool will:

1. Analyze the MKV file for subtitle tracks.
2. Extract supported subtitle languages.
3. Convert VobSub subtitles to SRT format.
4. Remux the SRT subtitles into a new MKV file named `subit.mkv`.

Supported languages (ISO 639-1 codes):

- English (en)
- Finnish (fi)

## Output

- `subit.mkv`: The resulting MKV file with converted SRT subtitles.
- Temporary files (`.srt`, `.idx`, `.sub`) are cleaned up automatically.
