Description

youtube-dl should be able to handle Youtube hashtag pages such as https://www.youtube.com/hashtag/rice . I can not find any information on converting these types of pages into proper playlists or even mix playlists to make this trivially doable.

Ideally I want to be able to grab a list of or download all videos with the hashtag, but also useful would be grabbing the top-n results displayed on the page (or in the batches that youtube loads as you scroll down).

This is the current output (no recognition of the list of videos):
