Camera Capture Diagnostics
Systematic troubleshooting for AVFoundation camera issues: frozen preview, wrong rotation, slow capture, session interruptions, and permission problems.
Overview
Core Principle: When camera doesn't work, the problem is usually:
- Threading (session work on main thread) - 35%
- Session lifecycle (not started, interrupted, not configured) - 25%
- Rotation (deprecated APIs, missing coordinator) - 20%
- Permissions (denied, not requested) - 15%
- Configuration (wrong preset, missing input/output) - 5%
Always check threading and session state BEFORE debugging capture logic.
