It used to show in real time no matter what. If I click that window to make the video the foremost, the preview will then show the window in real time. It can also be tweaked to work the way you want. For example, if I have 3 windows open - Youtube, Facebook, and Twitter - and a Youtube video is playing on Window 1, if Twitter's window is the foremost window and I hover over the taskbar, three window previews will show, but Youtube's preview will be a still image, not an active video. The Windows Taskbar lets you access frequently used and currently open apps.

Starting today, Chrome has stopped showing active video in the taskbar previews unless I am already on that window.
