As a part of adding new functionality to our existing plugin I was hoping to create a customised version of the PlaybackWpfUserControl, but found that the class is sealed. So is there another way to create a Playback Control (preferably WPF based but not essential) that has the same look and feel as provided in the Milestone client Playback?
Is there another way to customise the PlaybackWpfUserControl control given that the class is sealed?
I suggest you make you own control and then implement the commands the same way you see in the Video Viewer sample.
