AssertionError when using yt-dlp to download from YouTube through gallery-dl (update to newest version of gdl in the actions tab)

[ghost]

I've looked through my galler-dl config file, but I can't seem to figure out where I went wrong. I even did away with the yt-dlp config file and added all that data into gdl, but I still get the same error.

Just realized the formatting from copying to this issue is abysmal. Let me know if it's hard to read, and I will try to make it neater.

gallery-dl triggers this error by calling one of yt-dlp's functions with the wrong argument type. This probably happens when handling a playlist of playlists.

Thank you.

So I assume then that by trying to download a whole channel, EX: gallery-dl --verbose https://www.youtube.com/@ViralGenesis , it is then compiling a playlist of playlists as it notes here:

[ytdl][debug] [youtube:tab] Downloading as multiple playlists, separated by tabs. To download as a single playlist instead, pass https://www.youtube.com/playlist?list=UUwuMwHtnseX2g4qFg5COlOA

Is there any way to download whole channels, then, by specifying the channel link? Or will I need to go and download each tab separate (IE. the videos tab, live, shorts, etc.)?

[mikf]

Using https://www.youtube.com/@ViralGenesis as URL already downloads from all tabs, where each tab is given as a separate playlist by yt-dlp as I understand it, but gallery-dl combines them all into one big "playlist" anyway. Or you use https://www.youtube.com/playlist?list=UUwuMwHtnseX2g4qFg5COlOA as URL as stated by yt-dlp to have all channel videos in one real playlist.

[ghost]

Okay, thank you. Does gallery-dl -K <Youtube Channel> provide that link so I don't need to attempt download to find it?

[mikf]

It provides channel_id (UCwuMwHtnseX2g4qFg5COlOA) and channel_url (https://www.youtube.com/channel/UCwuMwHtnseX2g4qFg5COlOA), which only need some small changes to become https://www.youtube.com/playlist?list=UUwuMwHtnseX2g4qFg5COlOA, but I'm pretty sure you can just use https://www.youtube.com/@ViralGenesis and get the same results.

For this channel, https://www.youtube.com/@ViralGenesis is only missing two offline live streams that never started from a few years ago. It would probably be best if you asked the actual yt-dlp devs what's the difference between the two or searched their issue tracker.

[ghost]

Okay. Thank you. I think I understand now.

Have a good day.
