如何从 youtube-dl 的播放列表中的 Youtube 视频中提取上传日期、标题、URL 和持续时间？
How to Extract The upload dates, Titles, URLs and Durations from Youtube videos in a Playlist with youtube-dl?
我正在尝试从具有 youtube-dl 的特定播放列表的所有 Youtube 视频中提取 Upload Dates、Titles、URLs 和 Durations , 我不需要视频 - 只需要上面的数据。
到目前为止，我已经测试了 在这里建议的以下两种方法：
Youtube-dl's GitHub Doc Used as reference
The Playlist URL used for testing
方法#1
youtube-dl --skip-download --print-json https://www.youtube.com/playlist?list=PLRqwX-V7Uu6by61pbhdvyEpIeymlmnXzD > example.json
和
方法#2
youtube-dl --get-upload_date https://www.youtube.com/playlist?list=PLRqwX-V7Uu6by61pbhdvyEpIeymlmnXzD > example.txt
方法 #1 输出整个 json 转储——每个视频大约 3000 行——处理大量 Youtube 视频播放列表非常不方便——但它包含 4需要的数据。
APPROACH #2 returns 出现以下错误：
youtube-dl: error: no such option: --get-upload_date
我想支持 APPROACH #2 以将输出数据限制为仅需要的数据（upload dates、Titles、URLs和 Durations)，在 and after checking the upload_date is a valid youtube-dl option here Youtube-dl's GitHub Doc Used as reference.
之后
为什么 upload_data 选项没有得到验证？
有什么办法可以限制数据？
非常感谢您的有益建议。

然后我用谷歌搜索了错误
jq: error: syntax error, unexpected INVALID_CHARACTER, expecting $end (Windows cmd shell quoting issues?)
并从这个建议中找到了见解：
然后我相应地调整了你的 @pierpy youtube-dl 命令单引号到双引号：
youtube-dl --skip-download --print-json https://www.youtube.com/playlist?list=PLRqwX-V7Uu6by61pbhdvyEpIeymlmnXzD | jq "{"date": .upload_date,"title": .title,"URL": .url,"duration": .duration}"
现在它根据需要输出数据Upload Dates、Titles、URLs和Durations。
最终输出：

上一期：
获得的 URLs 不显示标准视频。
为什么不呢？
在 Youtube-dl's GitHub Doc Used as reference 中指出：
url (string): Video URL
如何检索标准的 Youtube 视频 URL？
最后一期答案：
我刚刚查看了昨天生成的 example.json 文件，发现标准的 Youtube 视频网址接受 webpage_url 代替 url。
最终 YOUTUBE-DL 输出：

您需要使用方便的工具过滤输出，例如 jq:
粘贴此命令行：
youtube-dl --skip-download --print-json https://www.youtube.com/playlist?list=PLRqwX-V7Uu6by61pbhdvyEpIeymlmnXzD | jq '{"date": .upload_date,"title": .title,"URL": .url,"duration": .duration}'

获得 jq
更新:
密钥 "webpage_url" 包含标准的 YouTube 网址，如果需要的话。
有关各种可能键的完整列表，运行:
youtube-dl --skip-download --print-json https://www.youtube.com/playlist?list=PLRqwX-V7Uu6by61pbhdvyEpIeymlmnXzD | jq keys

OSError: [Errno 22] Invalid argument

然后我用谷歌搜索了错误
jq: error: syntax error, unexpected INVALID_CHARACTER, expecting $end (Windows cmd shell quoting issues?)
并从这个建议中找到了见解：
然后我相应地调整了你的 @pierpy youtube-dl 命令单引号到双引号：
youtube-dl --skip-download --print-json https://www.youtube.com/playlist?list=PLRqwX-V7Uu6by61pbhdvyEpIeymlmnXzD | jq "{"date": .upload_date,"title": .title,"URL": .url,"duration": .duration}"
现在它根据需要输出数据Upload Dates、Titles、URLs和Durations。
最终输出：
C:\Users\###\Documents\youtube-dl>youtube-dl --skip-download --print-json https://www.youtube.com/playlist?list=PLRqwX-V7Uu6by61pbhdvyEpIeymlmnXzD | jq "{"date": .upload_date,"title": .title,"URL": .url,"duration": .duration}"

上一期：
获得的 URLs 不显示标准视频。
为什么不呢？
在 Youtube-dl's GitHub Doc Used as reference 中指出：
url (string): Video URL
如何检索标准的 Youtube 视频 URL？
最后一期答案：
我刚刚查看了昨天生成的 example.json 文件，发现标准的 Youtube 视频网址接受 webpage_url 代替 url。
最终 YOUTUBE-DL 输出：
C:\Users\###\Documents\youtube-dl>youtube-dl --skip-download --print-json https://www.youtube.com/playlist?list=PLRqwX-V7Uu6by61pbhdvyEpIeymlmnXzD | jq "{"date": .upload_date,"title": .title,"URL": .webpage_url,"duration": .duration}"

在 JSON 文件中获取最终输出：
youtube-dl --skip-download --print-json https://www.youtube.com/playlist?list=PLRqwX-V7Uu6by61pbhdvyEpIeymlmnXzD | jq "{"date": .upload_date,"title": .title,"URL": .webpage_url,"duration": .duration}" > example.json
您需要使用方便的工具过滤输出，例如 jq:
粘贴此命令行：
youtube-dl --skip-download --print-json https://www.youtube.com/playlist?list=PLRqwX-V7Uu6by61pbhdvyEpIeymlmnXzD | jq '{"date": .upload_date,"title": .title,"URL": .url,"duration": .duration}'
您可以从 https://stedolan.github.io/jq/download/
jq
更新:
密钥 "webpage_url" 包含标准的 YouTube 网址，如果需要的话。
有关各种可能键的完整列表，运行:
youtube-dl --skip-download --print-json https://www.youtube.com/playlist?list=PLRqwX-V7Uu6by61pbhdvyEpIeymlmnXzD | jq keys
这给出了原始 JSON.
