Now i am using this link
http://gdata.youtube.com/feeds/api/playlists/plalistID
to retrieve video from YouTube playlist. but the problem is
YouTube API v3
You need to request the PlaylistItems > list feed:
https://www.googleapis.com/youtube/v3/playlistItems?part=snippet&maxResults=25&playlistId=PLVfin74Qx3tV8bgAhzbfDpnfPoGmJWAcn&key=YOUR_API_KEY
The JSON returned by the API will contain these properties:
nextPageToken
prevPageToken
Pass one of these values in the pageToken
query string parameter to retrieve the next or previous "page" in the result set:
https://www.googleapis.com/youtube/v3/playlistItems?part=snippet&maxResults=25&playlistId=PLVfin74Qx3tV8bgAhzbfDpnfPoGmJWAcn&pageToken=xxYYzz&key=YOUR_API_KEY
The JSON also contains pageInfo.resultsPerPage
and pageInfo.totalResults
properties.
YouTube API v2 answer is here.
