Castero doesn't consider Youtube feeds as valid rss

[taziden]

Hi,
I'm not sure if this is an issue per se but I'm trying to import a youtube channel rss feed into castero and I encounter the following traceback:

Traceback (most recent call last):

I looked into the structure of those youtube feeds and it's definitely not RSS, so this isn't an issue with the parser. Theoretically it's not too different, but adding support for this format specifically would require rewriting quite a bit of code since there are many (imo reasonable) assumptions that feeds are valid RSS. This is something I might add in the future, but I don't think I'll plan on doing it at the moment.

It's not RSS but an Atom-Feed.
You may use python-feedparser, to read RSS and Atom feeds.

Would be very nice to have ATOM feed support :)
