Cloudinary 获取视频时长和资源

Question

如何使用 Node.js 和 cloudinary.v2.api.resources 获取 Cloudinary 视频持续时间以及其他属性？

您没有阅读过有关该主题的其他帖子吗？是的，我有。他们都说通过

image_metadata: true

。不起作用。

我正在这样搜索：

cloudinary.api.resources(
  {
    ...
    image_metadata: true,
  },
  (err: any, result: any) => {
    console.log(err, result);
  }
);

传入image_metadata：true，不返回视频时长。好吧，公平地说，它不会改变任何事情，而我得到了我想要的其他一切。

我错过了这方面的更新吗？一直在寻找它有一段时间但没有结果。 感谢您的任何建议！

Answer 1

这有效：

cloudinary.v2.api.resource(public_id, {
  resource_type: "video",
  media_metadata: true,
});

默认情况下，cloudinary api 会 ping 其 /image api。您必须声明视频，然后请求元数据才能获取持续时间。

Answer 2

上传视频后从云端获得的响应本身包含持续时间。因此您只需使用response.duration。 我的代码->

const videoFileLocalPath = req.file.path
const response = await uploadOnCloudinary(videoFileLocalPath)
console.log(response)

响应是->
