I know this question was asked many times at last time. I sought solution about it, but have not found. I suggest to do a good answer and attach this on first result position in search, that will be easy to find solution.
So, I use AJAX get request to get video from youtube server:
var url = 'http://gdata.youtube.com/feeds/api/videos/54d@fj9?v=2&alt=jsonc';
$.getJSON(url, function (data) {
//
});
But it gives me notice about changes API. How I can do it step by step? For this need registration?
This answer: Youtube API v3 , how to get video durations? But where I can get youtube key?
