Java

Xiaobian Diandian Using the built-in Robots class is easier than other Java libraries and may suit your needs. If you need a >=smooth video at 30fps (more than 30 screenshots per second)， you should first try to use the Robots method and the screenshot asynchronous storage feature in it to improve performance. If it doesn’t work for you – try using JNA – it’s almost guaranteed to work (even if more complex) with screen capture. Robots are close Robotics lessons can really do what you want，The problem with most screen capture methods using robots is the saving of the screenshot . One approach might look like this ： iterate over the captureScreen() method ， capture the screen into a BufferedImage ， convert it to a byte array， and in the future of the image After the reference is added to the object – save it to the target file using the async file writer. The ArrayList can move on while storing image data. // Pseudo code while (capturing) { grab bufferedImage (screenCapture) from screen convert bufferImage to byte array start asynchronous file channel to write to the output file and add the future reference (return value) to the ArrayList }…
