How can I embed a video from
<iframe src="//vk.com/video_ext.php?oid=162756656&id=171388096&hash=b82cc24232fe7f9f&hd=2" width="853" height="480" frameborder="0" allowfullscreen></iframe>
It seems like vk.com used to support
&t=1m14s parameter when it was using Flash video player, but they don't have such functionality since they moved to HTML player.
So the answer is - there is no way to do it.
