Description

As pointed out on https://github.com/ytdl-org/youtube-dl/issues/25065, nick.de uses a new stream infrastructure / new player similar to other Viacom channels like MTV.de, CC.com and nickjr.de (which are supported already). Therefore, nick.de links do not work with youtube-dl anymore.

Example links for single episode pages:

@luckydonald nope nick.de wasn’t part of it yet. However I made some fix for it which will be released within next few days

Sorry for the late response. I recently updated the mtv extractor. With minor modifications I can get nick.de working again.
