我正在尝试使用youtube-dl和ytsearchdate函数从youtube中提取信息。
下面的代码应该从25页中提取信息，但只提取了20页。
import youtube_dl
ydl = youtube_dl.YoutubeDL({"ignoreerrors": True})
results = ydl.extract_info("ytsearchdate25:"stackoverflow"", download=False)
Result logs

您在此处使用了错误的ytsearchdate25:
如果使用ytsearch+一些n作为25，则会得到25个结果
如果使用ytsearchdate，则基本上使用ytsearch:date:
所以实际上你的查询是这个ytsearch:date25:-这意味着你会得到一个月25日上传的所有视频(？(
我猜ytsearch默认返回值是20个视频(可能是youtube自己设置的(。
最终要得到您想要的结果，要么使用ytsearch25:，它将返回25个结果，要么ytsearch25:date25:，它将在第25天返回25个成果。我不太清楚日期是如何解释的——比当前日期早25天，或者一个月的最后25日，或者其他什么。
