 * description:
 *    There are two mode to displsy decoded picture in VO:
 *    (1) bind mode.
 *    (2) user-send mode.
 *
 *    To use bind mode, call HI_MPI_VDEC_BindOutput(). It is recommended.
 *    To use user-send mode, do as proc_recvPic() did. It is not recommended.
 *
 * remark: 
 *    How to send pictures to VO is totally left to user in user-send mode. 
 *    So it is more complicated, but also more flexible. User can do some 
 *    special control in user-send mode.
