# Media Coding Web - Configuration & Run Guide
|
||||
|
||||
To properly test and run this project, you will need to prepare your environment:
|
||||
|
||||
1. **Install Node.js & FFmpeg**:
|
||||
- Ensure Node.js (v18+) is installed.
|
||||
- Install **FFmpeg** on your system and make sure it is available in your PATH environment variable. The Node.js library `fluent-ffmpeg` requires it.
|
||||
|
||||
2. **AWS S3 / MinIO Configuration**:
|
||||
- Modify the `.env` file (copy from `.env.example`).
|
||||
- Add your `AWS_ACCESS_KEY_ID`, `AWS_SECRET_ACCESS_KEY`, `AWS_REGION`, and `S3_BUCKET_NAME`.
|
||||
- If using **MinIO**, ensure you set the `S3_ENDPOINT` (e.g., `http://127.0.0.1:9000`) and set `S3_FORCE_PATH_STYLE=true`.
|
||||
- Ensure your bucket has `.mp4` video files.
|
||||
|
||||
3. **Install Dependencies & Start**:
|
||||
```bash
|
||||
npm install
|
||||
npm start
|
||||
```
|
||||
|
||||
4. **Test Delivery**:
|
||||
- Open your browser to `http://localhost:3000`.
|
||||
- The application should display available `.mp4` items from your S3 bucket.
|
||||
- Click one video, and the Node server will begin to read the S3 stream and pipe it to FFmpeg, transcoding it into HLS segments inside the `/public/hls/` directory.
|
||||
- The frontend polls via `/api/status`, and once the index playlist is available, HLS playback starts!
