In the YouTube API docs I found this example:
https://gdata.youtube.com/feeds/api/videos?q=surfing&max-results=10&fields=entry[yt:statistics/@viewCount>1000000]
Which, of course, works fine.
Now, let's say I wanted to find all the videos that matched surfing, and had more than 1 like (should be quite a lot) - I tried changing it to this:
https://gdata.youtube.com/feeds/api/videos?q=surfing&max-results=10&fields=entry[yt:rating/@numLikes>1]
But it returns nothing.
The docs on yt:rating are here, and I appear to specifying the correct fields. So why am I not getting any results?
Try adding v2 to the URL:
https://gdata.youtube.com/feeds/api/videos?v=2&q=surfing&max-results=10&fields=entry[yt:rating/@numLikes>10]
The ratings don't appear in the first version of the API
