About the Project

We are building Studio-mac, a native macOS application designed for synchronized video playback (Rytmo band) in professional post-production environments. Integrated with ProTools, the app delivers precise timecode synchronization, high-frame-rate video output, and DRM-protected streaming, all while offering a rich web interface for administration and control.

Key Responsibilities

• Develop and maintain a native macOS application using Swift and Objective-C.
• Port the Rytmo band algorithm from C# to Swift with real-time performance optimization.
• Integrate advanced video playback using AVFoundation, supporting DRM (FairPlay, Widevine, PlayReady) and various formats (MP4, MOV, HLS, DASH).
• Implement GPU selection and support external video output using Blackmagic (DeckLink) and AJA SDKs.
• Ensure frame-accurate synchronization with ProTools using MTC, SMPTE, LTC, and ProTools Satellite Protocol.
• Develop and maintain backend APIs using PHP 8/7 (Laravel, Lumen) and frontend interfaces using JavaScript (Vue.js, React.js, Quasar).
• Optimize multi-threaded code for smooth UI responsiveness and zero-lag playback.
• Enable real-time network communication with WebSockets and TCP/IP.
• Conduct unit and functional testing using XCTest and advanced debugging techniques (CPU/GPU profiling, latency optimization).
