我正在使用Data API执行搜索。有时当我尝试显示视频结果时，我会收到以下类型的消息：
此视频包含来自EMI的内容， 谁在你的国家阻止它 版权理由。
如何确定视频是否无法播放，而是从搜索结果中显示此消息？
以下是我正在进行的搜索示例：
http://gdata.youtube.com/feeds/api/videos?q=Explosions+in+the+Sky+So+Long++Lonesome
这是第一个结果，我尝试显示并获取版权信息：

该结果中的哪些内容表示无法播放视频？
答案 0 :(得分：0)
我想你想要找"media:restriction" field。
例如试试这个：

答案 1 :(得分：0)
使用youtube api v3，videoLicense字段有三个可能的参数，请使用以下其中一个：
videoLicense=any
videoLicense=creativeCommon
videoLicense=youtube
开始了解你是否可以在youtube中播放它。如果您在youtube之外使用它，请尝试使用videoSyndicated查询。
videoSyndicated=true
允许您搜索可在youtube外播放的视频，例如在使用youtube的移动应用中播放。
