Discussion: Fast RAW image acquisition

[Rogerpi]

Hi,

I am making a simple ROS wrapper for the libcamera to grab images from the Raspberry Pi HQ camera and publish them as in a ROS topic.
I attempted to do as suggested in the wiki, but capturePhoto(cv::Mat &) is slow due to the continuous start & stop of the camera.

I wonder if you have any suggestions on how to start the camera and continuously capture images. I did a quick attempt to just comment the Teardown and Close calls inside capturePhoto but it crashes due to "Multiple IPAManager objects not allowed"

Thanks
