CaptureBeam Control

C++ module for camera discovery and control using various protocols.

Target Camera Brands

• Canon
• Nikon
• Sony
• Fujifilm (stretch)

Prospective Protocols

• PTP/IP (current focus)
• PTP/USB
• Bluetooth
• HTTP APIs
• Shutter release

Current features

• Wireless control of Canon camera shutter and exposure settings over PTP/IP
• Automatic PTP/IP vendor detection and API selection
• Decoupled camera control API using events to facilitate control over only a binary stream
• Rich packet API to allow flexible bidirectional packet definition and parsing to/from binary
• Minimal implementations of several protocols:
  • Buffered TCP sockets
  • PTP
  • PTP/IP
  • HTTP
  • XML
  • UDP multicast
• Easy portability to new platforms
  • Currently supports Windows and the ESP32 microcontroller (build with PlatformIO)
  • Will later add Linux/macOS and possibly Android

Upcoming features

• WiFi camera discovery using UPnP/SSDP
• Camera manager to automatically add/remove camera instances from discovery events
  • When complete, will allow full control/feedback of camera control and discovery over a single binary stream such as TCP or WebSockets
• PTP over USB (and possibly Bluetooth control)
• Support for Sony and Nikon cameras
• Interactive applications for desktop, mobile, and embedded
