[mjpeg @ 000000000058f1c0] error y=33 x=27 [mpjpeg @ 0000000000578420] Expected boundary '--' not found, instead found a line of 29 bytes [mpjpeg @ 0000000000578420] Expected boundary '--' not found, instead found a line of 55 bytes [mpjpeg @ 0000000000578420] Expected boundary '--' not found, instead found a line of 32 bytes

ifact i'm trying to save an image taken from ip camera with java. i just wanted to notice that i never had this error from internal computer camera and i used the same code.... this is my fonction:µ @FXML protected void takeAPic(){

    Mat takeAPic= new Mat();
    capture.read(takeAPic);
    Image img=mat2Image(takeAPic);

    BufferedImage image;
    image = SwingFXUtils.fromFXImage(img, null);

    saveImage(image);
}

public boolean saveImage (BufferedImage img) {

   if(img!=null){
    try {
        File outputfile = new File(val+"Saves.png");
        ImageIO.write(img, "jpg", outputfile);
        val++;
    } catch (Exception e) {
        System.out.println("error");
        logger.info(e.getMessage());
    }
    return true;
   }else{ return false;}
}
