Using JavaCameraView in OpenCV, I only get 14 frame per second. No calculation is done. Neither image processing, nor feature detection. Only receiving the camera frame intact. But FPS doesn't go over 14. Why is that?

Is it bad implementation or I'm missing something?

Are you building in release mode?

@StevenPuttemans, No. I just tried the sample projects. Does is make difference? How do I build in release mode?

it's sad, that it's so slow, but pretty normal.

also, there's a lot of stuff done already under the hood. image acquisition, yuv2bgr, opengl drawing
