Hello Kaspars ;
Thank you for your code.
But i have a question.
Is there any way that you can get all the playlists with their thumbnail as well?

I have a channel with different playlists.
I select the categories and run the videos by the playlists id.

But if i add a playlist into my channel, i have to add the playlist-id inside my code,
is there possible to get all the playlist-id numbers just with a name of the channel?
Thanks a lot in advance.
