double startSec = 51.632;
FileChannelWrapper ch = null;
try {
    ch = NIOUtils.readableFileChannel(new File("filename.mp4"));
    FrameGrab fg = new FrameGrab(ch);
    grab.seek(startSec);
    for (int i = 0; i < 100; i++) {
        ImageIO.write(grab.getFrame(), "png",
            new File(System.getProperty("user.home"), String.format("Desktop/frame_%08d.png", i)));
    }
} finally {
    NIOUtils.closeQuietly(ch);
