推荐答案

查看 YouTube API 参考，看来您有几个选择:

Looking at the YouTube API reference, it appears you have a couple choices:

指定格式"搜索剪辑时的参数:

Specify the "FORMAT" parameter when searching for a clip:

格式参数指定视频必须以特定的视频格式提供.您的请求可以指定以下任何格式:

The format parameter specifies that videos must be available in a particular video format. Your request can specify any of the following formats:

5 - 此视频的可嵌入播放器 (SWF) 的 HTTP URL.此格式不适用于不可嵌入的视频.开发者通常会在他们的查询中添加 &format=5，以将结果限制为可嵌入其网站的视频.

5 - HTTP URL to the embeddable player (SWF) for this video. This format is not available for a video that is not embeddable. Developers commonly add &format=5 to their queries to restrict results to videos that can be embedded on their sites.

或引用 yt:accessControl 元素:

Or reference the yt:accessControl element:

<yt:accessControl> 标签指示是否允许用户评价视频、添加视频评论、评价视频评论、添加视频回复或嵌入第三方网站上的视频.另一个设置指示 YouTube 是否可以在 YouTube.com 网站以外的 YouTube 资产上显示视频.

The <yt:accessControl> tag indicates whether users are allowed to rate a video, add comments about a video, rate comments about the video, add a video response to the video, or embed the video on third-party websites. Another setting indicates whether YouTube can show the video on YouTube properties other than the YouTube.com website.

语法类似于 <yt:accessControl action='embed' permission='allowed'/>

因此，在您的示例中，yt:format: "5" 行告诉您可以嵌入剪辑.

So in your example it looks like the line yt:format: "5" tells you the clip can be embedded.
