what's NVMEDIA_IPP_ISP_OUTPUT2_MODE_1 to NVMEDIA_IPP_ISP_OUTPUT2_MODE_5 stands for?

Hi,

I’m trying using isp output 2 by
./nvmipp_raw -cf …/ddpx-a.conf -c SF3324-CSI-A --o2 yuv420_8b --od o2

but the showed images are just super dark.

I also tried different output 2 mode:
./nvmipp_raw -cf …/ddpx-a.conf -c SF3324-CSI-A --o2 yuv420_8b --od o2 -m mode5

only mode5 gives correct images, others are all dark.

So can I ask what’s NVMEDIA_IPP_ISP_OUTPUT2_MODE_1 to NVMEDIA_IPP_ISP_OUTPUT2_MODE_5 stands for?

also I want to use different output format like:
./nvmipp_raw -cf …/ddpx-a.conf -c SF3324-CSI-A --o1 rgb_srgb_8b --o2 yuv420_8b --od o2 -m mode5

but the command gives me a error: [CheckSupportedIspOutput2Format:215] isp output1 and output2 format combination is not valid for mode 5
if use other mode, it just gives me dark images on output 2.

How to solve that?

Thanks

Dear wenbinjlumj,
My apologies for late responce. We are updating the nvmedia_ipp.h file to have the below details.

/*! Indicates a NON-HDR ISP pipeline must be set in the ISP component. */
 NVMEDIA_IPP_ISP_SINGLE_PIPELINE_MODE = (1 << 1),
     /*! Indicates the second ISP output mode 1 is selected, the output image
       *  is generated after Demosaicing. */
      NVMEDIA_IPP_ISP_OUTPUT2_MODE_1 = (1 << 4),
      /*! Indicates the second ISP output mode 2 is selected, the output image is
       *  generated after Demosaicing and chroma processing.*/
      NVMEDIA_IPP_ISP_OUTPUT2_MODE_2 = (2 << 4),
      /*! Indicates the second ISP output mode 3 is selected, the output image
       *  is generated after noise reduction.  */
      NVMEDIA_IPP_ISP_OUTPUT2_MODE_3 = (3 << 4),
      /*! Indicates the second ISP output mode 4 is selected, the output image
       *  is generated after color correction processing.  */
      NVMEDIA_IPP_ISP_OUTPUT2_MODE_4 = (4 << 4),
      /*! Indicates the second ISP output mode 5 is selected, the output image
       *  is generated after local tone mapping.  */
     NVMEDIA_IPP_ISP_OUTPUT2_MODE_5 = (5 << 4)

Can we get some further explanation on the original error, ‘isp output1 and output2 format combination is not valid for mode 5’? We would like to have two outputs from the ISP, one in RGB and another in YUV, with both having tone mapping applied. RGB and YUV work when a mode other than 5 is selected, but this is unacceptable as it leaves output port 2 looking very dark. Is it at all possible to do what I’m attempting or is it a hardware limitation?
