Question

如您所知，youtube具有一个属性，其中包含带有软编码视频的字幕。通过单击cc可以看到它。还有一个网站可以帮助一个人学习英语单词www.youglish.com的发音

该网站会在字幕视频中搜索给定的单词，并将其中的一部分与“say”一词一起带入。也就是说，它可以按字幕搜索视频。这样做的方式/方法/步骤是什么？此外，ibm的工作类似于that

Answer 1

您可以使用search.list请求以下视频:

具有closed caption。

与搜索词匹配。

在此示例中，这是针对启用了 search.list且与搜索字词 (迷人)匹配的搜索视频的 closecaption请求:

https://www.googleapis.com/youtube/v3/search?part=snippet&maxResults=4&q=charming&type=video&videoCaption=closedCaption&fields=items(id(channelId%2Ckind%2CvideoId)%2Ckind%2Csnippet(channelTitle%2Cdescription%2Ctitle))&key={YOUR_API_KEY}

Demo available in Google API Explorer:

结果如下:

{
 "items": [
  {
   "kind": "youtube#searchResult",
   "id": {
    "kind": "youtube#video",
    "videoId": "ztsbgEUzVpc"
   },
   "snippet": {
    "title": "CHARMING Official Trailer (2018) Demi Lovato, Sia, Animation Movie HD",

  },

}

不幸的是，并非所有返回的视频都有(在标题中)给定的单词-在这种情况下，单词是 Charming 。

因此，您必须循环播放 search.list响应中返回的视频，并选择确实具有给定单词的视频。

接下来，您可以通过传递 videoId获得标题:

您可以使用以下URL获取标题:

https://video.google.com/timedtext?type=track&v=<VIDEO_ID>&id=0&lang=en

通过修改URl并添加 videoId来检索标题的有效jsfiddle是 here。
