ScreenOtters
The Challenge // The Problem
Native screen capture APIs are notoriously complex to implement for multi-display setups, often failing to handle coordinate mapping and zone selection across heterogeneous monitors (4K, Ultrawide, etc.) in a performant way.
The Solution // Technical Implementation
The Strategy
Obsidian is a technical deep-dive into ScreenCaptureKit and CoreGraphics. The primary architectural challenge was solving the coordinate-space mapping for a 6-display setup, ensuring that ‘Zone Area’ selection remains accurate regardless of monitor arrangement or DPI scaling.
Core Features
- Zone Area Capture: Precise pixel-mapping for custom rectangular selection.
- Multi-Monitor Logic: Advanced handling of display boundaries for 6+ monitors.
- Agentic Development: Co-developed with Codex to navigate low-level Apple system frameworks.
- High-Performance Buffer: Real-time stream handling with minimal CPU overhead.
