FLVPlayback - isPlaying function

I need to tell whether my FLVPlayback instance is playing or not. The obvious thing seemed to be VideoState property. However it returns all of the following:

VideoState.DISCONNECTED
VideoState.STOPPED
VideoState.PLAYING
VideoState.PAUSED
VideoState.BUFFERING
VideoState.LOADING
VideoState.CONNECTION_ERROR
VideoState.REWINDING
VideoState.SEEKING

The problem is that I’m seeing BUFFERING and PLAYING overlap so this isn’t reliable. How else can I tell if a video is playing?
