# Usage

Run the project with the following command:

```bash
python pwdl.py --options
```

- Download a single video:
  ```bash
  python pwdl.py --id VIDEO_ID --name VIDEO_NAME
  ```
- Download multiple videos from a CSV file:
  ```bash
  python pwdl.py --csv-file FILE_PATH
  ```
- Start the shell:
  ```bash
  python pwdl.py --shell
  ```
- Start the WebUI:
  ```bash
  python pwdl.py --webui
  ```

# API Reference

The project provides several API endpoints for interacting with the video downloading service:

- **POST /api/create_task**: Create a new download task.
  - **Request Body**: JSON with 'id' (video ID) and 'name' (output file name).
  - **Response**: JSON with 'task_id'.
  
- **GET /api/progress/<task_id>**: Get the progress of a download task.
  - **Response**: JSON with progress information.
  
- **GET /api/get-file/<task_id>/<name>**: Download the completed video file.
  - **Response**: Video file download.
  
- **GET /key/vid_id**: Get the decryption key for a video.
  - **Query Parameters**: 'vid_id' and 'token'.
  - **Response**: JSON with 'key'.

These endpoints are also available without the '/api' prefix. For example, use `/create_task` instead of `/api/create_task`.

# Docker Usage

The Dockerfile is used to create a Docker image that encapsulates the entire application, including all dependencies.

## Building the Docker Image

Navigate to the project directory and run:

```bash
docker build -t shubhamakshit/pwdl .
```

## Running the Docker Image

Run the Docker image with:

```bash
docker run -p 5000:5000 shubhamakshit/pwdl
```

Access the application at `http://localhost:5000`.

# Shell Usage (Beta)

Start the interactive shell with:

```bash
python pwdl.py --shell
```

Available commands:

- `get_key <vid_id> <token>`: Get the decryption key for a video.
- `tkn-up <token>`: Update the token in the default settings.
- `exit`: Exit the shell.

Note: This feature is in beta and may change.
