OneNVR v2.0 Release Notes

Major Architecture Changes

This release introduces significant simplifications to the codebase for improved reliability and 24x7 operation stability.

Breaking Changes

⚠️ Storage Structure Change

  • Eliminated the intermediate /raw directory
  • Videos now write directly to date-specific directories: /storage/{camera}/{YYYY-MM-DD}/
  • Migration Required: Existing /raw directories should be manually cleaned up after upgrade

⚠️ File Movement Logic Removed

  • No more periodic moving of completed segments between directories
  • ffmpeg writes directly to final destination directories
  • Reduces I/O overhead and eliminates race conditions

New Features

Proactive Directory Management

  • System creates date directories before they're needed
  • Automatic next-day directory creation at 22:00 hours
  • Prevents ffmpeg failures during midnight transitions

Optimized Performance

  • Directory monitoring reduced to hourly checks
  • Concatenation uses ionice for reduced I/O impact during recording
  • Simplified restart logic with configurable cooldown periods

Improved Reliability

Better Process Management

  • Streamlined health checks with boolean status
  • Single restart() method replacing complex state tracking
  • Automatic recovery from network disruptions

Reduced Complexity

  • Removed redundant scheduled tasks
  • Consolidated multiple health check methods
  • Cleaner separation of concerns between components

Compatibility Notes

  • Configuration file format remains unchanged
  • Web interface unchanged - all existing URLs work
  • Docker volume mounts remain the same
  • Existing video files are compatible

Upgrade Instructions

  1. Stop the current OneNVR instance
  2. Update to v2.0
  3. Start the new version
  4. Manually move any video files from old /storage/{camera}/raw directory to date-specific directory if they exist
  5. Manually remove old /storage/{camera}/raw directories if they exist
  6. Monitor logs for successful directory creation and recording startup

Performance Improvements

  • 60x reduction in directory check frequency (1440 → 24 daily checks)
  • Eliminated file I/O operations for segment moving
  • Low-priority I/O scheduling for concatenation operations
  • Reduced CPU overhead from simplified health monitoring

Note: This release focuses on long-term stability and reduced resource usage for continuous 24x7 operation. The changes may require a brief setup period as the system creates new directory structures.
