(function() {
a = ytplayer.config.args.storyboard_spec;
if (!a) {
alert("Sorry we cannot process this YouTube video. Could you please try another one");
exit();
}
b = a.split("|");
base = b[0].split("$")[0] + "2/M";
c = b[3].split("#");
sigh = c[c.length - 1];
var imgs = "";
t = ytplayer.config.args.length_seconds;
n = Math.ceil(c[2] / (c[3] * c[4]));
for (i = 0; i < n; i++) {
imgs += "<PICTURE='" + base + i + ".jpg?sigh=" + sigh + "'><br/>";
}
var title = ytplayer.config.args.title;
msg = "<body style='background-color:#444;color:#eee;margin:20px auto;width:90%;text-align:center'><h2>TITLE</h2><div>IMAGES</div><br/><em><a href='http://labnol.org/?p=28217' style='text-decoration:none;color:#fff;font-style:bold'>Printed using the YouTube bookmarklet.</a></em></body>";
msg = msg.replace("TITLE", title).replace("IMAGES", imgs).replace(/PICTURE/g, "img src");
var labnol = window.open();
labnol.document.open();
labnol.document.write(msg);
labnol.document.close();
})();
当计算c
时，bookmarklet作者丢弃了其他三种尺寸，只留下160px（5x5）的尺寸
Ceil为9.68=10
如果我们将b[3]
替换为b[4]
，并修复添加到'3/M'
URL的'2/M'
，我们将获得更高分辨率的图像
简单替换为较大版本（某些视频没有最大版本，可能会失败）：
更新
这不在bookmarklet中，但实时视频情节串连板隐藏在bookmarklet中

结果是一样的，但谢谢…代码取决于youtube的分辨率…我总是下载视频，然后使用缩略图ME 3.0和4000宽度，第10行第8列制作视频的缩略图
