So any parameter values could be passed upstream to (potentially modified) routines. I'm posting this here as a reference, but I doubt it will be useful for anyone else since this issue When starting to update the old applications, mainly replacing picamera with picamera2 (that uses libcamera), the following warnings appear, which seem to indicate an incompatibility issue between the OS configuration and the picamera2/libcamera library. Another alternative would be to run in a faster preview mode, and then do a mode switch just for the capture. libcamera was born out of that collaboration and will offer modern camera support to Linux-based systems, including traditional Linux Camera works perfectly when capturing photos at full resolution or videos up to 3840x2160, but when trying to capture full 9248x6944 at 2.
