Features

• Automatic DeoVR browser detection
• Video metadata extraction (resolution, duration, codec, fps)
• Next/Previous video navigation
• Direct file serving for non-DeoVR clients
• Support for MP4, M4V and WebM formats
• In-memory file list caching for improved performance
• 3-hour HTML page caching for super fast navigation
• Auto-advancing random media cards

Command Line Usage

Install globally to use the CLI:

npm install -g deovr-server

CLI Options

• --port, -p: Set server port (default: 3000)
• --timeout, -t: Set filesystem operation timeout in milliseconds (default: 10000)
• Video directory path

Serve a video directory on port 3000:

deovr-server

Serve the video directory /media/videos on port 8080:

deovr-server -p 8080 /media/videos

Serve a directory with a longer timeout (30 seconds) for slow drives:

deovr-server -t 30000 /media/slow-drive/videos

Environment Variables

The following environment variables can be used to configure the server instead of CLI arguments:

| Variable | Description | Default | |----------|-------------|---------| | DEOVR_LIST_PORT | Server port | 3000 | | DEOVR_LIST_PATH | Video directory path | . | | DEOVR_FS_TIMEOUT | Filesystem operation timeout in milliseconds | 10000 |

Environment variables take precedence over CLI arguments and config file settings. Example usage:

DEOVR_LIST_PORT=8080 DEOVR_LIST_PATH=/videos deovr-server

Caching

The server implements several caching mechanisms to improve performance:

1. In-memory file list cache: File listings are cached in memory for 5 minutes to reduce filesystem operations.
2. File details cache: Metadata for files (size, duration, etc.) is cached for 1 hour.
3. HTML page cache: Rendered HTML pages are cached for 3 hours for super fast navigation.

Cache is automatically invalidated when files are modified (moved to/from the remove folder).

You can manually clear all caches by clicking the "Clear Cache" button in the UI or by making a POST request to /api/clear-cache.

Handling Slow or Sleeping Drives

The server includes timeout handling for filesystem operations, which is particularly useful when working with:

• External hard drives that may be in sleep mode
• Network attached storage (NAS) with slow response times
• Drives with very large directories containing many video files

If a filesystem operation times out, the server will:

1. Return a user-friendly error message
2. Continue functioning for other requests
3. Attempt to provide partial results when possible

You can adjust the timeout duration using the --timeout command line option or the DEOVR_FS_TIMEOUT environment variable. The default timeout is 10 seconds (10000ms).
