Создание видео

Вступление

Создание видео с помощью OpenCV (Java)

VideoWriter videoWriter;
videoWriter = new VideoWriter(outputFile, VideoWriter.fourcc('x', '2','6','4'),
                fps, frameSize, isRGB);
//We have stated that we will use x264 as codec with FourCC
//For writing, we add the following method and it will write the image we give as parameter in this call.
 public void Write(Mat frame) {
        if(videoWriter.isOpened()==false){
            videoWriter.release();
            throw new IllegalArgumentException("Video Writer Exception: VideoWriter not opened,"
                    + "check parameters.");        
        }
        //Write video
        videoWriter.write(frame);
    }

//With Video Capture for example, we can read images from the camera and write the same video

VideoCapture videoCapture = new VideoCapture(0);

                videoCapture.get(Videoio.CAP_PROP_FPS), frameSize, true);
while (videoCapture.read(mat)) {
            videoWriter.write(mat);         
        }
        videoCapture.release();
