带有ytsearchdate的youtube-dl仅返回20个结果

Question

我正在尝试使用带有ytsearchdate函数的youtube-dl从youtube中提取信息。

下面的代码应该从25页中提取信息，但实际上只提取了20页。

import youtube_dl
ydl = youtube_dl.YoutubeDL({"ignoreerrors": True})
results = ydl.extract_info("ytsearchdate25:\"stackoverflow\"", download=False)

Result logs

Answer 1

您在这里使用的ytsearchdate25:是错误的。

如果你使用ytsearch +一些n作为25，它会给你25个结果。

如果您使用的是ytsearchdate，那么您基本上就使用了ytsearch:date:。

所以实际上你的查询是这个ytsearch:date25: -这意味着你得到了在一个月的25号上传的所有视频(?)

我猜ytsearch的默认返回值是20个视频(可能是youtube自己设置的)。

最终，要获得您想要的结果，要么使用返回25个结果的ytsearch25:，要么使用返回第25天的25个结果的ytsearch25:date25:。我不太确定日期是如何解释的--比当前日期早25天，还是一个月的最后25号，或者完全不同的东西。
