del the nsf link pChObj->algObj.algCreateParams.format changed

now i found the other question ,i delete the nsf link ,then the enc channel can not be created successfully.

the following is the log :

4617.sessionNoEnc.log

also i just link the cap to enc directly ,the app can run normally,so i am confused.

the following is my dei configure

MULTICH_INIT_STRUCT(DeiLink_CreateParams, deiPrm[0]);
DeiLink_CreateParams_Init(&deiPrm[0]);
deiPrm[0].inQueParams.prevLinkId = dupId0;
deiPrm[0].inQueParams.prevLinkQueId = 0;
deiPrm[0].outQueParams[1].nextLink = ipcOutVpssId;//gVcapModuleContext.nsfId[0];
deiPrm[0].enableOut[1] = TRUE;
deiPrm[0].tilerEnable[1] = FALSE;
deiPrm[0].comprEnable = FALSE;
deiPrm[0].setVipScYuv422Format = FALSE;//TRUE;
deiPrm[0].enableDeiForceBypass = TRUE;
deiPrm[0].enableDualVipOut = FALSE;
//deiPrm[0].interlacedBypassMode = TRUE;
deiPrm[0].inputFrameRate[DEI_LINK_OUT_QUE_VIP_SC] = 60;
deiPrm[0].outputFrameRate[1] = 60;

deiPrm[0].outScaleFactor[DEI_LINK_OUT_QUE_VIP_SC][0].scaleMode = DEI_SCALE_MODE_ABSOLUTE;
deiPrm[0].outScaleFactor[DEI_LINK_OUT_QUE_VIP_SC][0].absoluteResolution. outWidth = 1920;
deiPrm[0].outScaleFactor[DEI_LINK_OUT_QUE_VIP_SC][0].absoluteResolution. outHeight = 1080;

so why?

The log shows encoder received no frames. DEI is correctly outputting 60 fps. There is a ipcFramesOut link that is outputiing 60 fps. Check you link connections by printing currentLink,nextLink,prevLink and prevLinkQueId for each link you create and confirm connections are correct.

i have check the link connection,and i think it is right

that following is cap my link
