Hi, if you want fast frame captures then I'd avoid "create_still_configuration". That's geared towards still image capture, therefore defaults to the highest resolution (which makes things slow), and also cuts down on the amount of memory so as not to run out (which can cause frame drops).
I'd go with "create_video_configuration" or "create_preview_configuration". Those will use more buffers, and you should tailor the size of both streams to you requirements. Displaying a low resolution version of the stream makes sense. I would only copy the higher resolution buffer out when OpenCV wants to use it, as copying a buffer is in itself relatively expensive.
