SignalForge Video

Planned

The SignalForge Video subsystem handles video capture, encoding, and integration with the display stack.

Features

• Hardware-accelerated video encoding/decoding through NPL drivers
• Zero-copy frame delivery via ION Rings
• Integration with the Surface Manager for compositor-level video surfaces
• Capability-controlled camera access

Architecture

Video frames flow through the same ION Ring infrastructure as all other Nexus IPC:

1. Camera NPL captures raw frames
2. Frames are placed on the application's ION Ring (zero-copy)
3. Application processes frames (encoding, analysis, display)
4. Processed frames can be submitted to the Surface Manager for display

Security

Camera access follows the same model as audio — explicit capability grant, ProvChain logging, HUD indicator, and user-revocable permissions. No application can access the camera without a visible, auditable capability.
