We all know source of active youtube videos in page source. I want to know not playing youtube videos. Basically if video is active, we can see video, iframe or object tags or whatever they used. But if video is inactive or not playing, we can also see video, iframe or object tags. Here i'd like to know how can we identify these two whether video is active or inactive in php script. If anybody does have experience, please share and let me know I'll be so thankful.
