Could I access android camera by c++ api(opencv4)?
As the title mentioned, try to google by the keywords "OpenCV4 android camera" or "OpenCV4 android camera c++" but cannot find the answers like "yes" or "no", I remember opencv3 do not support this feature.
I found the examples written by java, but I am not sure under the hood, it is using the android api or c++ api(cv::VideoCapture) to capture the frame with JNI binding.
