Description

Hi, Vlive revamped their site a couple of months ago. I checked and I have the latest version. The new vlive url is supported and you can download regular, non-paid videos, but when you try to download the vlive+ videos, an extractor error occurs.

https://www.vlive.tv/post/0-19850194 - this is the video I'm trying to download, it's behind a paywall. I have the +membership and even after putting my username and password, I am still unable to download the videos. An extractor error message pops up and recommends that I report it thus this post. Thanks!

FYI, this seems to be working now. I don't know what changed (didn't see a specific fix in the release history), but I'm able to download vlive+ videos now.
