Returning duration while listing playlistItems? - youtube

Question

I'm using this url:
https://www.googleapis.com/youtube/v3/playlistItems?
playlistId=FLFe0SGNFqZ9E2owO5ZDZpeg&
part=snippet,contentDetails,status
to fetch YouTube playlistItems.
I included all the part I'm interested in, however I found no way to return the duration of the item.
https://developers.google.com/youtube/v3/docs/playlistItems/list
Is this possible?
currently I'm getting back only an item like this:
{
"status": {
"privacyStatus": "public"
},
"kind": "youtube#playlistItem",
"contentDetails": {
"videoId": "tL-Ba86UhoE"
},
"snippet": {
"playlistId": "FLFe0SGeFqZ9E2owO5ZDZpwg",
"thumbnails": {
"default": {
"url": "https://i1.ytimg.com/vi/tL-BA86Uhoh/default.jpg",
"width": 120,
"height": 90
},
"high": {
"url": "https://i1.ytimg.com/vi/tL-BA86Uhoh/hqdefault.jpg",
"width": 480,
"height": 360
},
"medium": {
"url": "https://i1.ytimg.com/vi/tL-BA86Uhoh/mqdefault.jpg",
"width": 320,
"height": 180
}
},
"title": "Music Video",
"resourceId": {
"kind": "youtube#video",
"videoId": "tL-BA86Uhoh"
},
"channelId": "UCFe0SGNFqZ9E2owO5ZDZpwg",
"publishedAt": "2013-07-06T18:41:43.000Z",
"channelTitle": "channeltitle",
"position": 0,
"description": "Video for"
},
"etag": "\"ePFRUfYBkeQ2ncpP9OLHvB0fDw4/CJiCG6tvFw4quQlzJq3gTrhvCNo\"",
"id": "FL-fX6VqgtTfCJWKNE4aVRODKSrRgEdGvw"
},
With no time indication at all.
I'd rather avoid flooding YouTube with request to return a single video's duration.

Answer 1

Use link like this for get duration for many videos:
https://www.googleapis.com/youtube/v3/videos?part=contentDetails&id=idFirst,idSecond&key=YOUR_API_KEY

Answer 2

Use this Function : [ only used with Youtube Api v3 ]
Browser :
you have to make another http request
using :
https://www.googleapis.com/youtube/v3/videos?id={video id}&part=contentDetails&key={api Key}
and on
contentDetails
you will find the duration
Php :
function getDuration($apiKey,$video_id){
$link='https://www.googleapis.com/youtube/v3/videos?id='.$video_id.'&part=contentDetails&key='.$apiKey;
$data = json_decode(file_get_contents($link),true);
$duration = $data['items'][0]['contentDetails']['duration'];
return $duration;
}
