This milestone completes the video processor with full 360° video support: ## New Features - Complete 360° video analysis and processing pipeline - Multi-projection support (equirectangular, cubemap, EAC, stereographic, fisheye) - Viewport extraction and animated viewport tracking - Spatial audio processing (ambisonic, binaural, object-based) - 360° adaptive streaming with tiled encoding - AI-enhanced 360° content analysis integration - Comprehensive test infrastructure with synthetic video generation ## Core Components - Video360Processor: Complete 360° analysis and processing - ProjectionConverter: Batch conversion between projections - SpatialAudioProcessor: Advanced spatial audio handling - Video360StreamProcessor: Viewport-adaptive streaming - Comprehensive data models and validation ## Test Infrastructure - 360° video downloader with curated test sources - Synthetic 360° video generator for CI/CD - Integration tests covering full processing pipeline - Performance benchmarks for parallel processing ## Documentation & Examples - Complete 360° processing examples and workflows - Comprehensive development summary documentation - Integration guides for all four processing phases This completes the roadmap: AI analysis, advanced codecs, streaming, and 360° video processing. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
