How to enable universal decode mode(closed loop back by default) on HDVICP2 ?

Hi,  

I noticed that we have such comment in usecase file, but I can not figure out where the interface is.

Could you let me know how to turn on the universal mode, i hope it can help improve decode qualities.

I am asking because DM36x HDVICP support this feature.

/* Max ref frames is only 2 as this is closed loop decoder */
decPrm.chCreateParams[i].dpbBufSizeInFrames = 2;
decPrm.chCreateParams[i].numBufPerCh = NUM_DECODE_BUFFERS;
decPrm.chCreateParams[i].tilerEnable = TILER_ENABLE;
decPrm.chCreateParams[i].enableWaterMarking = gVdecModuleContext.vdecConfig.decChannelParams[i].enableWaterMarking;
}

BR,

Eason
