Using PiCamera v2 with full 3280x2460 resolution

[vthierry]

Hi,
i am using this raspicam.h in the https://gitlab.inria.fr/line/aide-group/aide project, really fine, and experiment bith raspicam::RaspiCam and raspicam::RaspiCam_cv with a PiCamera v2 which hardware characterisrics are e.g. there https://picamera.readthedocs.io/en/release-1.12/fov.html

But i only can use a 1280x960 while 3280x2460 resolution is possible, but it fails (see bug log below) it might be some buffer size is not large enough ?

Please.
Best.

P.S.: i gonna have side question : what is RaspiCam_Still ? it might be link with my question.

Hi @vthierry, I'm looking for the same information as you.
So far the highest resolution I could use without error is 1920*1920.
Anything more than that and I get the following errors:

mmal: mmal_vc_port_enable: failed to enable port vc.ril.camera:out:1(BGR3): ENOSPC
mmal: mmal_port_enable: failed to enable port vc.ril.camera:out:1(BGR3)(0x2022b60) (ENOSPC)
