Backend (Rust/Actix-web): - Add video_preview_clips table and PreviewDao for tracking preview generation - Add ffmpeg preview clip generator: 10 equally-spaced 1s segments at 480p with CUDA NVENC auto-detection - Add PreviewClipGenerator actor with semaphore-limited concurrent processing - Add GET /video/preview and POST /video/preview/status endpoints - Extend file watcher to detect and queue previews for new videos - Use relative paths consistently for DB storage (matching EXIF convention) Frontend (React Native/Expo): - Add VideoWall grid view with 2-3 column layout of looping preview clips - Add VideoWallItem component with ActiveVideoPlayer sub-component for lifecycle management - Add useVideoWall hook for batch status polling with 5s refresh - Add navigation button in grid header (visible when videos exist) - Use TextureView surface type to fix Android z-ordering issues - Optimize memory: players only mount while visible via FlatList windowSize - Configure ExoPlayer buffer options and caching for short clips - Tap to toggle audio focus, long press to open in full viewer Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
