Answer 1

查看YouTube API参考资料,您会看到以下几种选择:

搜索剪辑时指定"FORMAT"参数:

format参数指定视频必须以特定视频格式提供.您的请求可以指定以下任何格式:

5 - 此视频的可嵌入播放器(SWF)的HTTP URL.此格式不适用于无法嵌入的视频.开发人员通常会在其查询中添加&format = 5,以将结果限制为可嵌入其网站的视频.

或者引用yt:accessControl元素:

该<yt:accessControl>标记表示是否允许用户对视频评分,添加视频评论,评价视频评论,添加视频回复或将视频嵌入第三方网站.另一个设置表示YouTube是否可以在YouTube.com网站以外的YouTube媒体资源上显示该视频.

语法看起来像 <yt:accessControl action='embed' permission='allowed'/>

因此,在您的示例中,看起来该行yt:format: "5"告诉您可以嵌入剪辑.

Answer 2

从YouTube V3 API开始,embeddable状态部分中有一个字段.

例如https://www.googleapis.com/youtube/v3/videos?id=6CQEZ_kas0I&key=[yourkey]&part=snippet,contentDetails,status

"status": {
    "uploadStatus": "processed",
    "privacyStatus": "public",
    "license": "youtube",
    "embeddable": true,
    "publicStatsViewable": true
}

Answer 3

在YouTube V3 API中,要仅返回可嵌入的视频,请添加 videoEmbeddable=true参数.你也必须使用type=video这个来工作.
