Clone the repository:\n ```bash\n git clone \n cd \n ```\n2. Build and run the application using your preferred IDE or a build tool like Maven:\n ```bash\n mvn spring-boot:run\n ```\n\n#### Using Docker\n1. Verify that Docker and Docker Compose are installed on your system. If not, refer to the official installation guides for [Docker](https://docs.docker.com/get-docker/) and [Docker Compose](https://docs.docker.com/compose/install/).\n2. Build and run the Docker container:\n ```bash\n docker-compose build\n docker-compose up\n ```\n\n#### Adding Video Files\n- **Default Directory**: The application uses the `./video` directory for video content by default.\n- **Custom Directory**: To use a custom directory, set the `VIDEO_CONTENT_PATH` environment variable to point to your desired location.\n- **Mounting Volumes**: When running in Docker, mount the desired video folder as a volume in the container to include additional video files.\n\nExample of mounting a directory: docker-compose.yaml\n```yaml\nservices:\n video-service:\n volumes:\n - /path/to/local/video/folder:/tmp/content\n```\n\n## Streaming Endpoint\nThe application provides an HTTP streaming endpoint to serve video content.\n\n### Endpoint Format\n- URL: `/video-service/api/v1/videos` - Will list the all video files in the directory\n- URL: `/video-service/api/v1/videos/stream/{fileType}/{fileName}`\n - **`fileType`**: The format of the video file (e.g., `mp4`, `mkv`).\n - **`fileName`**: The name of the video file without the extension.\n- URL: `/video-service/api/v1/videos/object-key/{objectKey}` - prefer to use this endpoint\n - **`objectKey`**: Object key of the file, can get the object key by hitting the `/video-service/api/v1/videos` \n\n### Example Request\nOnce the application is running, you can access the streaming service with the following format:\n```\nhttp://{host}:{port}/video-service/api/v1/videos/stream/{fileType}/{fileName}\n```\nFor example:\n```\nhttp://localhost:8080/video-service/api/v1/videos/stream/mp4/toystory\n```\n\n### Customizing the Video Directory\nTo change the default video content directory:\n1. Set the `VIDEO_CONTENT_PATH` environment variable.\n ```bash\n export VIDEO_CONTENT_PATH=/path/to/your/video/directory\n ```\n2. Restart the application to apply the changes.\n\n## Testing and Debugging\n### Unit and Integration Tests\n- The project includes unit and integration tests to ensure functionality. Use the following command to execute tests:\n ```bash\n mvn test\n ```\n\n### Logging\n- The application uses configurable logging via `logback.xml`. Logs are stored in the `logs` directory by default.\n- To change the logging level, modify the `application.properties` file or the `logback.xml` configuration.\n\n### Common Issues\n1. **Port Already in Use**:\n - If port `8080` is occupied, modify the port in the `application.properties` file:\n ```properties\n server.port=9090\n ```\n2. **File Not Found**:\n - Ensure that video files are present in the specified directory.\n - Verify the `VIDEO_CONTENT_PATH` environment variable if using a custom directory.\n\n\n## Further Reading\nFor an in-depth explanation of how this service is implemented, including details on HTTP-based video streaming using Spring Boot, check out [this Medium article](https://medium.com/@saravanastar/video-streaming-over-http-using-spring-boot-51e9830a3b8).\n\n" }, { "path": "docker-compose.yaml", "content": "services:\n video-service:\n build:\n context: ./\n dockerfile: Dockerfile\n volumes:\n - ./video:/tmp/content\n environment:\n VIDEO_CONTENT_PATH: /tmp/content\n ports:\n - 8080:8080\n\n\n" }, { "path": "mvnw", "content": "#!/bin/sh\n# ----------------------------------------------------------------------------\n# Licensed to the Apache Software Foundation (ASF) under one\n# or more contributor license agreements.
