List all video on youtube

Question

I'm looking for a way to list every video on youtube. you have any ideas for it?

YouTubeQuery query = new YouTubeQuery(YouTubeQuery.DefaultVideoUri);
query.Query = "";     //<-Research key//
query.OrderBy = "viewCount";
query.SafeSearch = YouTubeQuery.SafeSearchValues.None;

Feed<Video> videoFeed = request.Get<Video>(query);

In this way, youtube return only 1.000.000 of result.

Answer 1

From Youtube Api page;

The tag has a maximum value of 1,000,000. As such, if the tag value is 1,000,000, you can be sure that there are not exactly one million results but rather that there are so many matches that we just stopped counting. In addition, the maximum value for this tag is 1,000,000.
