Description

youtube-dl redirects youtube.com/user/channel/live to the wrong video which is not even a live broadcast (is_live is null instead of true) :

$ youtube-dl -j https://www.youtube.com/user/NewCreationChurch/live --playlist-items 1 | jq -r '.title, .id, .is_live'
华文崇拜（2020年10月10日至12日）| 新造教会 ・ Mandarin Service (10–12 Oct 2020) | New Creation Church
YL8WCTghMsg
null

instead of pointing to where the browser points that is to say https://www.youtube.com/watch?v=xRHIySE7S6Y :

$ youtube-dl -j https://www.youtube.com/watch?v=xRHIySE7S6Y --playlist-items 1 | jq -r '.title, .id, .is_live'
Joseph Prince at New Creation Church | 2.30pm

true

Please note that the URL https://www.youtube.com/user/NewCreationChurch/live is only available once a week.

I'm having the same issues.
It's not detecting the correct stream ID using the channel name /live

I'm having the same issues too from 2 days ago.
It seems youtube-dl cannot fetch the live stream but get the whole playlist that the channel has in their video.
