Graphics Development Server

test video

This project was born out of a need to improve my remote development workflow. Traditional solutions like Remote Desktop or Parsec create too much friction, and native X11 forwarding doesn't work on Windows. This repository serves as a proof-of-concept for selectively forwarding a single remote application window to a local client.

Technical approach & Progress

The current iteration focuses on the capture pipeline rather than the networking layer. To capture frame with minimal overhead, I implemented:

  • DLL injection & Function Hooking - to intercept the OpenGL render loop.
  • Frame Capture - extracting raw frame data from the graphics context.
  • Encoding - using FFmpeg to encode and mux captured frames into an mp4 container.

Project status

While successful as a specialized OpenGL capture tool, this approach is limited. I have since discovered the native Windows Capture API, which offers a more robust solution for client area window capture.

Active development will be moved in the future to a new repository. This repository remains as a demo of the DLL injection and OpenGL hooking solution.

Requirements

  • CMake 3.30
  • MinGW 13.2.0 MSVCRT (or equivalent)
  • vcpkg

Dependencies

  • FFmpeg
  • minhook
  • Boost ASIO (not used)

Building

git clone github.com/Rocco2300/graphics-dev-server

cd graphics-dev-server
mkdir build && cd build
cmake .. -G "MinGW Makefiles" -DBUILD_SHARED_LIBS=OFF -DCMAKE_TOOLCHAIN_FILE=<path_to_vckpg.cmake> -DVCPKG_TARGET_TRIPLET=x64-mingw-static
cmake --build .

cd ../bin
./graphics-dev-srv.exe <path_to_app>

Keep in mind that you will have to modify the path from server.cpp to point to your bin directory.
