I am trying to transform C++ program into a java program. There are a few lines I can't transform:

long totalFrameNumber = capture.get(CV_CAP_PROP_FRAME_COUNT);
capture.set(CV_CAP_PROP_POS_FRAMES, frameToStart-3);
double rate = capture.get(CV_CAP_PROP_FPS); 
cvtColor( frame,fgray, CV_BGR2GRAY );

These macros ,CV_CAP_PROP_FRAME_COUNT, CV_CAP_PROP_POS_FRAMES, CV_CAP_PROP_FPS, CV_BGR2GRAY ,cannot be found in the OpenCV for Java. What should I do?

How are you?

I'm not sure but you should write CAP_PROP_FRAME_COUNT not CV_CAP_PROP_FRAME_COUNT.
