Ticket Name: Linux/TDA2: Two Encoder Link For video Saving

Query Text:
Part Number: TDA2 Tool/software: Linux Hi Every one, I am working on a use case that could save video on SD card in TDA2xx. For that I am using Two Encode link. I have created the usecase as below :- Capture -> VPE -> Dup_vpe -> SgxFrmcpy (A15) ->Dup_sgx Dup_vpe -> Encode_vpe -> Null_vpe (A15) Dup_sgx -> DssM2mWb - > Encode_sgx -> Null_sgx (A15) Dup_sgx -> Display_M4 (IPU1_0) GrpxSrc -> Display_Grpx while compiling , it show an error : 'SYSTEM_LINK_ID_VENC_1' undeclared 1) How can i solve this problem ? 2) Can i define SYSTEM_LINK_ID_VENC_1 and how ? Regards, Renjith

Responses:
Hi, You can use only 1 instance of encoder link. Multiple instances are not supported for encoder link. Regards, Anuj

Hi Anuj, Thank you for your reply.. Is there any other option for this ? Can i use one Encoder link instead of using two ? How its possible ?

Hi, Please modify usecase as below Capture -> VPE -> Dup_vpe -> SgxFrmcpy (A15) ->Dup_sgx Dup_vpe -> Merge Dup_sgx -> DssM2mWb - > Merge Merge -> Encode -> Select -> Null_vpe (A15) Select -> Null_sgx (A15) Dup_sgx -> Display_M4 (IPU1_0) GrpxSrc -> Display_Grpx Regards, Anuj

Hi Anuj, 1) By using this usecase can i save both videos at the same time ? 2) How to configure the 'Select' ?

Hi, Please take reference of the usecase where select link is used. Regards, Anuj

Hi, Is the issue resolved? Regards, Anuj

Hi Anuj, Sorry for the late reply, While running i got this error Assertion @ Line: 700 in iva_enc/encLink_common.c: 0 : failed !!!

Hi, Have you set pLinkChPrm->format params? Please take a reference of encoder link params from the below usecase file. vision_sdk\apps\src\rtos\usecases\vip_single_cam_view_encdec\chains_vipSingleCam_EncDec_Display.c Regards, Anuj
