如何从云存储中获取文件并作为本地文件处理而无需下载？

Question

I am working on a project where I have to extract frames from a video by using ffmpeg (node.js). I first upload video to firebase storage from my client, and then I want to process it in the backend server. However, ffmpeg only accept file as if it is stored locally.

const ff =new ffmpeg('C:/Users/alexh/Desktop/alex/name.avi');

It will not work with url. I am wondering is any way I can get file from url as if it is stored locally or firebase can provide me a way to get the file? I don't want to use filebase trigger event because I want to send http request to backend server.

Thank you so much

如果您是在Linux或OS X上运行的，则可以使用GCS Fuse将存储桶安装到文件系统上，然后直接将FFmpeg指向它。

The fluent-ffmpeg package supports operating on readable streams instead of just files. The GCS Client library supports creating a readable stream for a GCS object . By combining these you can has ffmpeg operate directly from GCS.
