Apple Silicon-optimized Moonlight game streaming client

Nightlume is an open source fork of Moonlight PC built exclusively for Apple Silicon Macs, featuring hardware-accelerated video decoding via VideoToolbox and Metal rendering optimizations.

• Hardware-accelerated VideoToolbox decoding - H.264, HEVC, and AV1 codec support
• Optimized Metal renderer - Apple Silicon-specific rendering pipeline
• Native CoreAudio - Low-latency audio with proper buffer management
• HDR streaming support - Full HDR passthrough on supported displays
• YUV 4:4:4 support - Enhanced color accuracy (Sunshine only)
• 7.1 surround sound - Full spatial audio support
• Gamepad support - Force feedback and motion controls for up to 16 players
• 10-point multitouch - Touch input passthrough (Sunshine only)

This fork includes Apple Silicon-specific improvements over upstream Moonlight:

• Enhanced Metal renderer - Optimized shader pipeline in vt_metal.mm
• MetalFX integration - Apple's native upscaling technology
• Improved overlay system - Better performance overlay rendering
• Frame pacing improvements - Smoother playback with enhanced pacer

• Native CoreAudio renderer - Bypasses SDL for lower latency
• Proper buffer management - Optimized for Apple Silicon audio subsystem

• macOS Performance Manager - QoS tuning, power management, thermal optimization
• XPC Helper Service - Privileged operations via launchd
• Debug logging infrastructure - Comprehensive macOS-specific diagnostics

Key areas of modification from upstream:

• app/streaming/macos/ - Performance infrastructure and helper protocol
• app/streaming/video/vt_metal.mm - Metal renderer optimizations
• app/streaming/audio/renderers/coreaudio.mm - Native audio renderer
• app/helper/ - XPC helper service
• app/shaders/vt_renderer.metal - Metal shader enhancements

• macOS 13+ (Ventura or later)
• Apple Silicon Mac (M1, M2, M3 series)
• Xcode 14+ for building from source
• Qt 6.7+ SDK
