How can I go to specific time in video using opencv?

I'm trying to capture the video. If I input 00:00:10, I want to go to that time of video and capture it.

Now, I get the duration of video. And If the duration is same with input time, I stop and capture it. But that takes too much time.

int timing = cap.get(CAP_PROP_POS_MSEC);

How can I solve this problem?

You can use the function

bool cv::VideoCapture::set ( int propId, double value )

with

propId = CAP_PROP_POS_MSEC //Current position of the video file in milliseconds.

Example: 

VideoCapture openCVCapture("video1.mp4");
openCVCapture.set(cv2.CAP_PROP_POS_MSEC,20000)      //jump to 20 sec
openCVCapture >> image;

More information is in Opencv docs
