Youtube “Invalid category filter” API error

votes

I am trying to create a Youtube RSS feed for the most popular videos for a given category, using the demo API page: https://gdata.youtube.com/demo/index.html

This works just fine with one of their standard API calls: http://gdata.youtube.com/feeds/base/standardfeeds/most_viewed?alt=rss&time=today

However, as soon as I add a category to it, I get a 400 error ("Invalid category filter"): http://gdata.youtube.com/feeds/base/standardfeeds/most_viewed/-/{http://gdata.youtube.com/schemas/2007/categories.cat}Music?alt=rss&time=today

I have tried urlencoding it, urlencoding just the last part, encoding just the curly brackets... but can't seem to get it to work.

Any solutions would be most appreciated.

Show some of the code you tried - Barmar
I was just loading these into my browser - although I got exactly the same problem trying to collect them through Magpie RSS reader for PHP - AnthonyVader

Actually, I just worked it out - If you click on the 'edit URI before submitting' check box, it provides an encoded version of the URI which does work.
