I had a similar problem. What I did was left the Ipod for a good few days (I assume to let it fully drain out of battery? Not sure) and then plugged it in and it started charging. It worked for me, hopefully for you to. Good luck.
It sounds like your camera is damaged in some way, have you dropped it? Try taking it back to the store you bought it from because sometimes there is an expert onsite that can help, or give you a refund. Good luck.
