We need to change something when extracting these channels. It returns 404 because NewPipe adds a /c/ before gaming, which isn't recognized by YouTube.

what about the music channel?

[AudricV]

For the music channel, this channel has no Videos tab. Channel extraction on NewPipe Extractor relies currently on the Videos tab for now. Some work for the channel tabs extraction has been already made in #279. However, someone needs to reuse the work already made to create a new PR rebased on the dev branch.
