Facebook API PHP - Getting number of likes of a posted video

I want to get number of likes of a video, posted on a facebook page in video section...

I dont know what I'm doing wrong.

If I pass this,

$response=$facebook->api("/PAGE ID/videos");

I'm getting all posted videos of my PAGE. But I can't get the number o开发者_开发百科f people who like the video. I'm sure more number of people is liking the video.

Please help me with this.

Thanks.
