Quick Overview & Repository

💻 GitHub Repository — Complete open-source Tauri v2, Rust, and React 19 codebase.
⚡ Desktop Architecture: Native Rust daemon with WebAudio and Canvas overlays on Tauri 2.0.

Overview

MediaMir is an all-in-one modern desktop media center that fuses local and remote Jellyfin streaming, sequential BitTorrent streaming, and IMDb 18+ Parents Guide parental diagnostics, while acting as the flagship reference player for the CensorFlow (.censor.json) content redaction format.

Built to overcome the resource bloat and latency of Electron-based streaming clients, MediaMir executes lightweight streaming, native Cast discovery via mDNS, and frame-accurate content filtering with minimal CPU and memory footprints.

Key Highlights & Architecture

1. Real-Time Sequential BitTorrent Streaming

Instant Playback: Streams media chunks sequentially via magnet links or .torrent files directly into the player buffer without waiting for full file downloads.
Smart Partial Resumption: Detects existing partial downloads on disk, infers piece bitfields, and resumes stream sessions in-place.
Multi-File Navigation: Seamlessly inspects multi-file torrent contents and streams selected files on demand.

2. Flagship CensorFlow Reference Player

CanvasCensorRenderer: Frame-accurate Gaussian blur, pixelation, and blackout bounds over sensitive visual regions.
AudioCensorEngine: Real-time Web Audio API gain ducking, muting, and 1000Hz censorship bleep tones for profanity or inappropriate dialogue.
SkipEngine: Intelligent automated scene jumps for violent, graphic, or sensitive segments with countdown indicators.
Universal Export: Exports censor cues to standard .edl (Edit Decision List) for VLC, Kodi, and Jellyfin.

3. TV Casting & Bidirectional Handoff

Native Discovery: Automatic discovery of Chromecast and Google Cast receivers via native Rust mDNS and SSDP.
Bidirectional Playback Handoff: Seamlessly switch playback between PC and TV without losing time position, audio sync, or volume state.
Second-Screen Companion Mode: Use mobile or desktop web interfaces as interactive remote controllers.

4. IMDb 18+ Parents Guide & Popcorn Integration
