A desktop application for media file management, metadata editing, codec detection, and re-encoding.
Seer (Tamil: சீர்) — to prune, order, uniformity, neatness.
- Advanced File Browser — Navigate directories with context menus, bulk selection, and file operations (rename, move, copy, delete, new folder, reveal in Finder/Explorer)
- Media Analysis — View detailed codec information and stream analysis for video, audio, subtitles, and attachments
- Bitrate Analysis — Interactive bitrate graphs with per-stream visualization, statistics, and peak detection
- Export Options — Export bitrate charts as PNG (theme-aware), or data as JSON/CSV
- Stream Management — Inspect stream metadata (language, title, flags) and remove unwanted streams
- Metadata Display — View file metadata using ffprobe
- SQLite Caching — Persistent database for job tracking, analysis caching, and file metadata caching with hash-based validation
- Cross-Platform — Native experience on macOS, Windows, and Linux with Tauri
- Theme Support — System, light, and dark themes
- Metadata Editing — Edit EXIF, ID3, and Matroska tags
- Re-encoding — FFmpeg-based transcoding with presets and hardware acceleration
- Batch Processing — Queue operations for multiple files
- File Organization — Custom naming templates and automatic organization rules
- Frontend: React + Vite + TypeScript
- Backend: Tauri (Rust)
- Database: SQLite (via tauri-plugin-sql)
- State Management: Zustand
- Media Processing: FFmpeg / FFprobe
- Code Quality: Biome (formatting & linting)
Seer uses a SQLite database for persistent caching with automatic invalidation:
- File Metadata Cache — Caches file metadata and ffprobe data with hash-based validation
- Bitrate Analysis Cache — Stores computed bitrate analysis results
- Job Tracking — Persistent queue for background processing tasks
Cache validation uses a file hash computed from:
- File size
- Modification time (mtime)
- First and last 8KB of file content (SHA-256)
When a file changes, the hash changes, and cached data is automatically invalidated.
