how to set vip mode dynamically

bin li2

can i set vip parameters dynamically without deleting and creating all the links, just deleting and creating only capture link?

when i use vip1 port A ,i set it 16bits wide. and then i run the demo.

if i want to change the vip1 port A to 8 bits wide dynamically ,

after TI employee help me ,i just know the direction , but i dont know the details.

now i use this plan to change vip ,but it can not work .my plan is:

System_linkStop(capID);

System_linkDelete(capID);

config capture paramaters

System_linkCreate(capID);

System_linkStart(capID);

i need help .thank you very much

now i change the process flow like bellow:

System_linkStop(capID);

System_linkControl(capID,cmd...);

System_linkStart(capID);

in capture link cmd , i do little change like this:

Int32 CaptureLink_drvRecreateVip1PortA(CaptureLink_Obj * pObj, UInt16 instId, UInt16 DVIorAV)
{
CaptureLink_InstObj *pInst;
Vps_CaptCreateParams *pVipCreateArgs;

if(DVIorAV > 1)
return -1;

pInst = &pObj->instObj[instId];
pVipCreateArgs = &pInst->createArgs;

///DVI
if(DVIorAV == 0)
pVipCreateArgs->videoIfMode = VPS_CAPT_VIDEO_IF_MODE_16BIT;
else///1-AV
pVipCreateArgs->videoIfMode = VPS_CAPT_VIDEO_IF_MODE_8BIT;

/* VIP capture */
FVID2_delete(pInst->captureVipHandle, NULL);
pInst->captureVipHandle = NULL;

pInst->captureVipHandle = FVID2_create(FVID2_VPS_CAPT_VIP_DRV,
pInst->instId,
pVipCreateArgs,
&pInst->createStatus, &pInst->cbPrm);

UTILS_assert(pInst->captureVipHandle != NULL);

return FVID2_SOK;
}

but it does not work as i wish.

Pls refer this post where capture stop/start is implemented successfully on DVR RDK 4.0
