When attempting to add the Atom feeds for YouTube Channels, sometimes TT-RSS will be unable to find the feed.
I've been running into this issue since YouTube disabled v2 of their data API, and I decided to try my hand at writing a plugin to fix it.

The problem is that some channel pages don't seem to link to their Atom feeds, yet others do. I do not know what causes this.
The result of this problem is that some RSS feeds for YouTube channels can be added to TT-RSS simply by pasting the YouTube channel URL in the Add Subscription box, yet for other channels this will result in TT-RSS (correctly) stating there are no feeds on the page.

The plugin I ended up making is a bit of a hack: Whenever you try to subscribe to a URL like this: youtube.com/channel/<channel id> (e.g. https://www.youtube.com/channel/UCX20tFFXihWdnuOtEyag5EA) the plugin will translate this into a subscription for the Atom feed. YouTube uses these URLs when you click the channel name below a YouTube video.

It does not work for URLs like youtube.com/user/<nickname>.

Installation instructions
-------------------------

Extract the youtube_subscription directory from the ZIP-file into your plugins or plugins.local directory of your TT-RSS installation.
Then enable the youtube_subscription plugin in your TT-RSS settings.
Now subscribing to youtube.com/channel/<channel id> URLs should correctly add the relevant Atom feed subscription.
