I am unable to get video to play reliably in codenameone - codenameone

Question

I am at the point of abandoning using codenameone to build an app that allows me to play video from storage or to capture and play. Its either it is playing but no video is showing (most common ) or it plays only once and thats it - the fast forward and rewind buttons not working. I don't know if this is a simulator problem/limitation or whether I just don't know what I am doing.
