If you want a GUI for your webcam project, install the Lazarus IDE ( sudo apt install lazarus ). It provides a Delphi-like environment that makes designing camera dashboards much easier. Pascal Webcam Raspberry
If you are doing heavy lifting, look into the V4L2 memory mapping ( mmap ) to pass frames directly to the GPU. Helpful Resources program RaspberryWebcam; uses cv, highgui; // OpenCV units
First, ensure you have the Free Pascal Compiler and the essential video headers installed on your Raspberry Pi: sudo apt update sudo apt install fpc libv4l-dev Use code with caution.
