What is the correct syntax for requesting all YouTube channel videos?

Question

YouTube

Previously Query View

gdata.youtube.com/feeds/api/users/channel/uploads?alt=json-in-script&callback=showVideos

And the json list was returned,
now you only work with the playlist

gdata.youtube.com/feeds/api/playlists/...

And for all videos, the default stub returns.

Answer 1

The answer is off topic, but many plugins for working with YouTube stopped working, apparently changes were made to the API, this is bad ...
