我想从Youtube上检测视频是否可播放。我目前正在检测版权侵权,可嵌入和“可以联合”的限制。我在API中调用两次,一次在版本3中,一次在版本2中调用这些:
http://gdata.youtube.com/feeds/api/videos/{videoId}?v=2&alt=jsonc
https://www.googleapis.com/youtube/v3/videos?id={videoId}&key={key}&part=status
对于视频(https://www.youtube.com/watch?v=TzmyOT1kcfc),我得到了以下答案:
{
"kind": "youtube#videoListResponse",
"etag": "\"kjEFmP90GvrCl8BObMQtGoRfgaQ/yoB7kT2xS4cnv1zDF-EiUrfidKQ\"",

}
]
}

所以我看到的是视频既可以“联合”(可在手机上查看)又可嵌入,但它不可嵌入(https://www.youtube.com/embed/TzmyOT1kcfc?autoplay=true ==&gt;刷新页面)。该视频正在我的Android应用中播放,因为我正在使用官方Youtube SDK,因此我猜测,对于Google,我的应用程序的这部分是Youtube的一部分。
问题是:为什么在这两个调用中,API告诉我它是嵌入式的,而绝对不是?
我发现通过以“autoplay = true”作为参数启动嵌入式播放器,我可以在返回的HTML中查找“ytp-error html5-stop-propagation”类,但是解析它会非常昂贵每个Youtube视频的HTML。您是否有其他方法可以了解视频是否真的可以嵌入?
最后一个问题:我点击了我在这个主题上提供给你的嵌入式播放器,它是第一次工作,但是当你刷新页面时却没有。为什么呢?
答案 0 :(得分:0)
一小部分视频的内容所有者将其应用于域级白名单或黑名单。这些限制未反映在API响应中 您无能为力。由视频的内容所有者决定可以在哪里嵌入视频
