YouTube频道中“发布视频”和“上传”的区别是什么？以及如何通过YouTube Data v3 API获取这些数据？

Question

我正在使用YouTube Data v3 API开发一个YouTube客户端，并且正在播放两个不同的频道:

1. Go Pro Channel： https://www.youtube.com/user/GoProCamera/videos
2. YouTube策划的体育频道：https://www.youtube.com/channel/UCEgdi0XIXXZ-qJOFPf4JSKw/videos

在Go Pro频道中，我还可以选择视频过滤器：“上传”、“喜欢”和“发布视频”。我对“上传”和“发布视频”过滤器很困惑，据我观察，在这个频道上，它们给出的结果是一样的。但是在YouTube精选的体育频道中，只有“发布视频”选项。

在过去的几个小时里，我无法从YouTube v2/v3的API文档中找到任何明确的解释，更让我困扰的是，我无法找到任何API来检索这些频道中的视频条目数据。

对于Go Pro频道，我至少可以依靠这里提到的方法来获取上传的视频：如何使用新的YouTube数据API（V3）获取某个频道的上传视频列表？

但对于策展频道，即使此方法不起作用，频道查询结果中给出的播放列表始终为空：

Hundreds of sports exist, from those requiring only two participants, through to those with hundreds of simultaneous participants, either in teams or competing as individuals. Sport is generally recognised as activities which are based in physical athleticism or physical dexterity, with the largest major competitions such as the Olympic Games admitting only sports meeting this definition, and other organisations such as the Council of Europe using definitions precluding activities without a physical element from classification as sports. However, a number of competitive, but non-physical, activities claim recognition as mind sports.\nThis channel was generated automatically by YouTube's video discovery system.",

在我看来，现在这是一个死胡同，那么有没有办法从这种策划的频道中获取视频？

Answer 1

如果您已经获得了策展频道的频道ID，则可以使用搜索endpoint获取视频；例如，此API调用将接收添加到YouTube体育频道的50个最新视频：
