TDA2X: How to record multi cam 3d srv data (data format issue)

VPE hardware does not support ARGB as input format.

You could use Display pipeline to convert ARGB to YUV format, but it is available in VSDK 3.1.

Hi Brijesh:

    Thanks for your suggestion!

    I can't found any display pipeline information in VSDK 3.1.

    Could you indicate which usecase has display pipeline example or provide sample code.

    Thank you!

    Regards,

Hi Brijesh:

    I add DSS M2M WB link to lvds_vip_multi_cam_3d_srv, and output connect to Encode.

    When I run the apps.out, it happend    

[HOST] [IPU2 ] 52.804520 s: dispcore/src/vpscore_dss.c @ Line 434:
[HOST] [IPU2 ] 52.804672 s: Core for this instance is already opened
[HOST] [IPU2 ] 52.804764 s: dispdrv/src/vpsdrv_displayCore.c @ Line 405:
[HOST] [IPU2 ] 52.804855 s: Dss core open failed!!
[HOST] [IPU2 ] 52.804916 s: dispdrv/src/vpsdrv_displayApi.c @ Line 326:

[HOST] [IPU2 ] 52.805099 s: Assertion @ Line: 326 in displayLink_drv.c: pObj->displayHndl != NULL : failed !!!

    My wbInNode and inPipelines[0U] parameter are:

/* DSS M2M WB link */
pUcObj->DssM2mWbPrm.enableOut = TRUE;
pUcObj->DssM2mWbPrm.wbInNode = DSSM2MWBLINK_DISPC_WB_IN_NODE_LCD2;
pUcObj->DssM2mWbPrm.numInPipeLines = 1U;
pUcObj->DssM2mWbPrm.inPipelines[0U] = DSSM2MWBLINK_DISPC_PIPE_VID3;

    Any wrong setting?

    Regards,

    Josh 

Hi Brijesh:
    I disable the display path(mark Sgx3Dsrv -> Display_M4), and Link DSS WB (Sgx3Dsrv -> DssM2mWb(IPU1_0) -> Encode -> Null_rec (A15))
    in chains_lvdsVipMultiCam_Sgx3Dsrv.txt.

    But it happened "Display Controller registration failed for dss core instance 0" on line 465 of VpsCore_dssOpen function of vpscore_dss.c

    Another question, Why the DSS WB use vpscore_dss.c instead of vpscore_dssWb.c in my actually execution?
