您提到的两个视频对我来说似乎是可以加载和播放的。例如，使用： Google代码游乐场，然后将视频插入选项标签

Both videos you mentioned appear to be loadable and playable for me. For example use: the google code playground and insert your videos into the option tags of the HTML.

不过，这里有一些提示。

Here's a few tips though.

• 使用您的gdata请求中使用v = 2参数来使用当前的YT数据API。


• 此博客文章列出了一些其他限制，您可能需要检查这些限制才能确定视频可播放或可嵌入。


• 有些视频可以嵌入，但不能播放。在这种情况下，您唯一可以做的就是使用JavaScript PlayerAPI查找表示正在播放的 stateChange 事件，然后使用 setInterval 可以通过 getCurrentTime 来轮询视频，以查看视频是否正在播放。对于大多数应用程序来说，这有点疯狂。

• Use the "v=2" parameter in your gdata request to use the current YT data API.
• This blog post lists several additional restrictions that you may need to check for to determine if a video playable or embeddable.
• Some videos can be embedded, but don't play. In that case the only thing you can do is to use the JavaScript PlayerAPI to look for a stateChange event that says that it's playing, and then use a setInterval to poll the video through getCurrentTime to find out if it is actually playing. This is a little crazy for most applications though.
