how to fetch download url via proxy, then download files without proxy?

[retsyo]

As the title says, I can't visit some video site directly, but if I visit it via proxy in firefox, then I can get the video file's url via Video DownloadHelper addon. Then the video file's url can be used by download application( for example, Internet Download Manager) without proxy

My proxy is not so fast and has bandwidth limitation, so my question is can we fetch download url via proxy, then download files without proxy?

thanks

By using --geo-verification-proxy. Of course particular extractor must support this.

In fact, I have read the document and known there is an option --geo-verification-proxy.

But I think I misunderstand in 2 ways before:

1. --geo-verification-proxy is used for breaking region restriction,
2. all download (including real url from page source file, and data file from real url) use `--proxy'

and now it is clear that --geo-verification-proxy is used for

1. breaking region restriction
2. downloading real url from page source file

`--proxy' for data file from real url

So bad, my proxy is still valid to visit the video site and to play the video in Firefox. The video file's url can be found via Video DownloadHelper addon, and can be download by Internet Download Manager without proxy

but for youtube-dl, the --geo-verification-proxy option failed:
