Cycle 2 HTML 5 Video Plugin play/pauze 只对奇数有效，对偶数无效

Question

所以我正在为 Cycle2 幻灯片插件制作一个 HTML5 视频插件。

什么是有效的：

第一张幻灯片视频自动播放，如果视频播放完毕，它会自动转到下一张幻灯片。如果下一张幻灯片是视频，它会自动播放那个。如果您在幻灯片之间切换，则会暂停上一张视频幻灯片并播放新幻灯片。视频幻灯片上的超时被禁用，因此可以播放整个视频

什么不起作用：

单击 .cycle-slideshow 时

Play/Pauze 视频元素。这是部分工作！发生的情况是 p/p 在您第一次看到幻灯片时工作完美，但在您第二次看到该幻灯片时却无法正常工作。第 3 次。第4次没有。

所以在 ODD 上有效，在 EVEN 上无效！

(function($) {
$(document).ready(function() {
// We add a class for targetting
$('.lsss-video').parent().addClass('cycle-slide-html5video');

// We assign a id to this class
