Hi  Loren,
Thank you for your reply.
Are you saying that

 when  pic->reference ==3  means  a valid reference frame and need to be 
           pic->reference ==1 means  a frame pending to be output and no 
longer be referred to
           pic->reference ==0 means a freme has been outputed and will 
no longer be refered to?

Best regards
