Hi,

I want to know if there is a chance to change the FPS of the camera, so i get into "onCameraFrame" function less often?

If there is no way to do it, what can i do if i want to perform image processing in a real time and do not let the value of the inputframe to change in the middle of the calculation.

Thanks

You can get access to android.hardware.Camera object via JavaCameraView and force fps. There is example Tuturial-3-CameraControl, that demonstrates how to control android camera directly. I recommend you to start from this sample.

You need to set correct camera parameters with Camera.Parameters class. Camera.Parameters.setPreviewFpsRange is what you need. http://developer.android.com/reference/android/hardware/Camera.Parameters.html#setPreviewFpsRange%28int,%20int%29
