How to retrieve the recents video uploaded on friend's channel?

Question

Theorically this is the api I need:

https://developers.google.com/youtube/2.0/developers_guide_protocol_subscriptions#Retrieving_new_subscription_videos

In fact, if I click on https://www.youtube.com/my_subscriptions I see the recent video uploaded by friends (subscriptions).

But calling that endpoint (alt=json) I get this:

        ],

                },
                "uri": {
                    "$t": "http://www.youtube.com/"
                }
            }
        ],
        "generator": {
            "$t": "YouTube data API",
            "version": "2.1",
            "uri": "http://gdata.youtube.com"
        },
        "openSearch$totalResults": {
            "$t": 0
        },
        "openSearch$startIndex": {
            "$t": 1
        },
        "openSearch$itemsPerPage": {
            "$t": 25
        }
    }
}

where in fact there are not any "videos" feed.

Where am I wrong?

Answer 1

something like this maybe

https://gdata.youtube.com/feeds/api/users/[userID]/subscriptions?v=2&alt=json or https://gdata.youtube.com/feeds/api/users/[userID]/newsubscriptionvideos?v=2&alt=json

dont forget to add your youtube userID which you can find in

https://www.youtube.com/account_advanced

now if you want to display someone else subscriptions but you dont know their userID you may have authenticate using OATH 2.0

or just go with

https://gdata.youtube.com/feeds/api/users/[youtube_username]/newsubscriptionvideos?v=2&alt=json
