/*
* 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.
