Rock 3A extremely low performance in GStreamer

ROCK 3 Series 3A
13

That’s why i provided this: Rock 3A Camera support - #10 by avaf

camera-mode = <0>;
or
camera-mode = <1>;

Edit:

maybe you should also use:

vid_capture.set(CAP_PROP_FRAME_WIDTH, capture_width);
vid_capture.set(CAP_PROP_FRAME_HEIGHT, capture_height);
vid_capture.set(CAP_PROP_FPS, framerate);

I think the modern way (v4l2) is:

cv::VideoCapture cap;
cap.open(index, cv::CAP_V4L2);
if (!cap.isOpened())
{
    std::cerr << "***Could not initialize capturing...***" << std::endl;
    return -1;
}
cap.set(cv::CAP_PROP_FRAME_WIDTH, capture_width);
cap.set(cv::CAP_PROP_FRAME_HEIGHT, capture_height);
cap.set(cv::CAP_PROP_FPS, framerate);
