Question

Can you use javascript to detect if the video is playing? paused? or stopped?

I know VLC under browsers can do this, but don’t know how to do it without VLC?

Answer 1

You can query the media object to get the playback state:

http://www.w3.org/TR/2011/WD-html5-20110113/video.html#playing-the-media-resource

“A media element is said to be potentially playing when its paused
attribute is false, the element has not ended playback, playback has
not stopped due to errors, the element either has no current media
controller or has a current media controller but is not blocked on its
media controller, and the element is not a blocked media element.”
