RapidPixel SDK

v1.23.0

RapidPixel SDK is a set of C++17 libraries and sample applications for video processing: capture, coding, streaming, tracking, object detection, stabilization, filtering, communication, logging, and lens/camera control. Its CMake project builds available modules into one static library on Linux or with MSVC on Windows, and supports source integration, a portable SDK bundle and OS installation. Modules can also be used through their own projects. Availability, acceleration and achievable frame rate depend on the operating system, hardware, input size and installed dependencies; a hardware-specific backend does not work on every CPU. Start with the build and installation guide and check the documentation of the modules selected for your application. The image below shows the functionality covered by the RapidPixel SDK:
