A VNC server providing a custom framebuffer.

You can inherit from the VncdConnection class as per the sample, and respond to the simple framebuffer and input callbacks. This design allows using the VNC/RFB protocol as a wrapper for arbitrary graphical tasks.


• Supports raw, zlib, ZRLE, and TightPNG image encoding
• Supports optional VNC authentication
• Single-threaded asynchronous design supporting multiple simultaneous clients
• Tested working with TightVNC Viewer 2.7 and RealVNC Viewer 4.1
• Tested compilation with Visual Studio 2013, but cross-platform/compiler ports should be trivial
• Designed to be connected to a custom framebuffer implementation


Unlike most other VNC implementations (e.g. libvncserver, QEMU-kvm, and RealVNC), no code in this project is based on the original GPL'd source code release of AT&T VNC. This project is a clean implementation from RFC6143, made freely available under non-copyleft software license (along with all its bundled dependencies):
