Picamera2 directly uses the Python bindings supplied by libcamera, although the Picamera2 API provides access at a higher level. Consider interactions with other AE features, such as aperture and aperture/shutter priority mode, and decide if control of which features should be automatically adjusted shouldn't better be handled through a separate AE mode control. Using libcamera in a C++ application. 0+rpt20240617-1. libcamera - Making complex cameras easy. . We may look at whether it is feasible to make a wrapper such that the API matches that of picamera and so some existing examples still work, but not at the moment. They implement std::enable_shared_from_this<> in order to create new libcamera. The aim is to put together something that’ll use the Picamera2 library and its QtGL SlySven's answer is good, but I'd suggest this might be more easily accomplished with the new gpiozero library too. The API exposes full control of the device to upper layers of libcamera through the public API, making it the highest level object libcamera exposes, and the object that all other API operations interact with from configuration to capture. Picamera2 also presents an easy to use Python API. It supports iterators and operates as a vector of StreamConfiguration instances.
