[Unreleased]

[1.0.0] - 2024-08-25

Added

  • Initial release of react-native-video-recompression
  • Smart Video Processing: Automatic strategy selection (passthrough/rewrap/recompress)
  • Video Analysis: Comprehensive video metadata extraction and codec detection
  • Quality Preservation: Lossless format conversion when recompression isn't needed
  • Custom Compression: Fine-tunable quality, bitrate, resolution, and codec settings
  • Progress Tracking: Real-time progress callbacks for long-running operations
  • Cross-platform support (iOS and Android) with native performance
  • TypeScript support with full type definitions
  • Native implementations:
    • iOS: Uses AVFoundation with intelligent export preset selection
    • Android: Uses MediaMuxer, MediaExtractor, and MediaCodec with optimal strategy selection
  • Background processing to avoid UI blocking
  • Comprehensive error handling and reporting
  • Support for various video formats and codecs
  • Audio track preservation during all processing modes
  • React Native autolinking support

Core Features

  • ✅ Video Analysis: Extract detailed metadata without modification
  • ✅ Smart Processing: Automatic optimization strategy selection
  • ✅ Quality Preservation: Lossless rewrapping when appropriate
  • ✅ Custom Compression: User-controlled quality and format settings
  • ✅ Progress Callbacks: Real-time processing updates
  • ✅ Cross Platform: Native iOS 11.0+ and Android API 21+ support
  • ✅ Background Processing: Non-blocking operations
  • ✅ TypeScript Support: Full type safety and IntelliSense

Processing Strategies

  1. Passthrough: File is already optimal, no changes made
  2. Rewrap: Changes container format while preserving video/audio quality
  3. Recompress: Applies compression settings to reduce file size or change quality

Technical Implementation

  • iOS: AVAssetExportSession with smart preset selection and custom export settings
  • Android: MediaMuxer/MediaExtractor with MediaCodec integration and Kotlin coroutines
  • Memory-efficient processing for large video files
  • Automatic codec detection and compatibility checking
