    Hi all,

    I ever used
    system("screencapture ./xx.bmp");
    in my program.

    It works but will freeze the screen a little bit.
    Actually I want to capture the screen every 1 second.
    So if a video is playing, the capture function causes the video not playing smoothly.
    Any suggestions?

    Thanks a lot for your reply!!
