Description

When i attempt to download an instagram reel (tik tok knockoff), youtube-dl uses the generic parser, which fails (first failing HEAD command, then failing generic extractor)

Since this new "feature' seems to be more of a UI/UX change, I'm hopeful that the only thing youtube-dl needs are some minor changes to invoke the instagram extractor on URLs that have '/reel/' in them.

Example reel: https://www.instagram.com/reel/CDUMkliABpa/

Until the merge request is merged, you might want to just replace reel by p in the URL to download the video anyway.

I tried the first post in the above link and replaced reel with p but it still doesn't work:
