## 🚀 Getting Started

1. **Download builds from [release](https://github.com/umlx5h/LLPlayer/releases)**

2. **Launch LLPlayer**

Please open `LLPlayer.exe`.

3. **Open Settings**

Press `CTRL+.` or click the settings icon on the seek bar to open the settings window.

4. **Download Whisper Model for ASR**

From `Subtitles > ASR` section, please download Whisper's models for `whisper.cpp`.
You can choose from a variety of models, the larger the size, the higher the load and accuracy.

Note that models with `En` endings are only available in English.

`Audio Language` allows you to manually set the language of the video (audio). The default is auto-detection.

If you want to use the `faster-whisper` engine instead of `whisper.cpp`, please download the engine instead of models from the settings.
With `faster-whisper`, selected model is automatically downloaded the first time, so no prior download is required.

A description of each engine can be found [here](https://github.com/umlx5h/LLPlayer/wiki/Whisper-Engine).

5. **Set Translation Target Language**

To use the translation function, please set your native language. This is called the `target language`.
The `source language` is detected automatically.

From `Subtitles > Translate` section, please set the `Target Language` at the top.

The default translation engine is `GoogleV1`.

If you want to use another translation engine, you will need to configure it in settings. You will find detail information in [here](https://github.com/umlx5h/LLPlayer/wiki/Translation-Engine).

6. **Play any videos with subtitles!**

You can play it from the context menu or by dropping the video.

For online videos, you can also play it by pasting the URL with `CTRL+V` or from context menu.

There are two `CC` buttons on the bottom seek bar.

The left is the primary subtitle and the right is the secondary subtitle.
Please set your learning language for the primary subtitle and your native language for the secondary subtitle.

Adding external subtitles is done in the same way as for videos, either by dragging or from the context menu.

7. **Open CheatSheet**

You can open a built-in CheatSheet by pressing `F1` or from ContextMenu.

All keyboard and mouse controls are explained.
Keyboard controls are fully customizable from the settings.
