# Command-Line playback

1. **Dragon player** is the default media player in the **Debian** system. If **Dragon player** is not installed, you can execute the following command to install it:

```bash
sudo apt update
```

2. If a prompt appears, please enter your password and wait for the installation to complete. After installing **Dragon player**, you can use the following command to open the video:

```bash
dragon /path/to/video/file
```

3. Replace **"/path/to/video/file"** with the actual path and file name of the video to be played. For example, if your video is located in the **Videos** folder of the home directory and named **"myvideo. mp4"**, the command would be as follows:

```bash
dragon ~/Videos/myvideo.mp4
```

**Dragon player** can decode all video formats supported by the **FFmpeg** library, including mainstream formats such as **MP4**, **AVI**, **MKV**, **WMV**, **FLV**, and **MOV**.
