Raspberry Pi 5 and Arducams

[henri]

the max res for simultaneous capture is 7445x6000

"Unable to request 2 buffers: Cannot allocate memory" with 2 64mp cameras

An idea popped in my head. Lets say 1 buffer that driver or libcamera makes somewhere for each camera in and another 2 buffers the that are made in the user application. so 4 buffers in total 4xrgb7445x6000 is ~511.20MB … dual capture works 4xrgb7446x6000 is ~511.28MB … dual capture does not work anymore as in the docs it is specified that when configuring CMA from /boot/config.txt the largest option is dtoverlay=vc4-kms-v3d,cma-512 and 511.28MB is strangely close to 512 @Dion eventhough…
