hi,i am work 8168 on DVR4.0

frames  M3 VPSS -> A8 ,if i want to save the frames in A8.how can i do?

in the multich_vcap_venc_vdis.c ,have this link  frames M3 VPSS -> A8 -> M3 VPSS display

        ipcFramesInHostPrm.cbCtx = &gVcapModuleContext;
        ipcFramesInHostPrm.cbFxn = Vcap_ipcFramesInCbFxn;

what is this?i want to know its specific function?i can not find  Vcap_ipcFramesInCbFxn,i just find a function Void Vcap_ipcFramesInCbFxn(Ptr cbCtx),but here it is not a funtion call.

then i need to save the frames into A8,i do not want it to M3 VPSS to display,how should i do.

in your sayings,invoke VcapVenc_ipcFramesCreate function,what is meaning? in the .c file,it does not call this function.

second:

in the multich_vcap_venc_vdis.c,encoded bits from M3 video to A8,how it saved in the A8.

i find this function  MultiCh_ipcBitsInitCreateParams_BitsInHLOS(&ipcBitsInHostPrm[0]);  in below section:

    ipcBitsInHostPrm[0].baseCreateParams.inQueParams.prevLinkId    = gVencModuleContext.ipcBitsOutRTOSId;
    ipcBitsInHostPrm[0].baseCreateParams.inQueParams.prevLinkQueId = 0;
    ipcBitsInHostPrm[0].baseCreateParams.numOutQue                 = 1;
    ipcBitsInHostPrm[0].baseCreateParams.outQueParams[0].nextLink   = SYSTEM_LINK_ID_INVALID;     MultiCh_ipcBitsInitCreateParams_BitsInHLOS(&ipcBitsInHostPrm[0]); 

that function,how does it do?save bits in A8? is it?

thanks very much,best regards.
