How to get byte[] more efficient?

Application: Java client(FrameGrabber)->websocket.sendBinary->php Server(Imagick->readImageBlob)

grabber = FrameGrabber.createDefault(1);
grabber.setFormat("dshow");
grabber.setBitsPerPixel(8);
grabber.setImageWidth(1920);
grabber.setImageHeight(1080);
grabber.start();
System.out.println("Before frameToByteArray Time: " + System.currentTimeMillis());
byte[] imageBytes = frameToByteArray(frameMat);
System.out.println("After frameToByteArray Time: " + System.currentTimeMillis());
// Send image data as binary message
websocket.sendBinary(imageBytes);

public static byte[] frameToByteArray(Frame frame) throws IOException {
    BufferedImage image = Java2DFrameUtils.toBufferedImage(frame);
    ByteArrayOutputStream os = new ByteArrayOutputStream();
    javax.imageio.ImageIO.write(image, "jpg", os);
    return os.toByteArray();
}

Result

Before frameToByteArray Time: 1687021694023
After frameToByteArray Time: 1687021694124

Time needed for such Frame to byte[] operation is about 100ms

Is there more efficient way? Can i get byte[] directly from Frame and php Imagick can decode it?
