I use the ndk interface to successfully open the camera, but fps and other parameters can not be set

camera_status = ACameraManager_getCameraCharacteristics(cameraManager, selectedCameraId,
                                                        &cameraMetadata);

camera_status = ACameraManager_openCamera(cameraManager, selectedCameraId,
                                          &deviceStateCallbacks, &cameraDevice);
ACameraCaptureSession_setRepeatingRequest(captureSession,&captureSession_captureCal
lbacks, 1, &captureRequest, NULL);

Hi,

parameters like the FPS are set on the capture request:

- https://developer.android.com/ndk/reference/group/camera#acapturerequest

- https://developer.android.com/ndk/reference/group/camera#acapturerequest_setentry_i32

e.g.:

> int32_t fpsRange[2] = {fps, fps};
> ACaptureRequest_setEntry_i32(captureRequest, ACAMERA_CONTROL_AE_TARGET_FPS_RANGE, 2, &fpsRange[0]);

Regards

I try to set fps 30 or 15. 

the count of image every second from camera is same.this is not 30 or 15 to output.

please 

int32_t mFramerateRange[2] = {30,30};

or

int32_t mFramerateRange[2] = {15,15};

ret = ACaptureRequest_setEntry_i32(mCapture_request, ACAMERA_CONTROL_AE_TARGET_FPS_RANGE,2,mFramerateRange);
