Hi, is there a way to take the output SciBufObj of NvMedia2D as the input of NvMediaIEP? I created NvMedia2d and NvMediaIEP in one process. The output SciBufObj of NvMeida2d is created with the attributes list which is filled through NvMedia2DFillNvSciBufAttrList(). when I feed the SciBufObj to NvMediaIEP，NvMediaIEPFeedFrame() will not return NVMEDIA_STATUS_OK. But if I create SciBufObj with the attributes list filled by NvMediaIEPFillNvSciBufAttrList(), the IEP function will run well. So, how to share SciBufObj between NvMedia2D and NvMediaIEP?

Dear @neo.chen,
Is the application pipeline is srcBuf → nvm2D → dstBuf → Encoding?

and are you using same NvSciBufAttrList obj to fill 2D and IEP properties? If so, please check using seperate NvSciBufAttrList obj to fill 2d and IEP properties and do reconcile using NvSciBufAttrListReconcile() like below.

NvSciBufAttrList list2D;
NvSciBufAttrList listIEP;
NvSciBufAttrList lists[2];

lists[0] = list2D;
lists[1] = listIEP;

NvMedia2DFillNvSciBufAttrList(list2D);
NvMediaIEPFillNvSciBufAttrList(listIEP);

Reconcile(lists, 2U, ...);
