TDA4VEN-Q1: Does TDA4VEN csitx support yuv input？

Hi Ling,

What issue are you facing for CSITX output? Yes, it does support YUV422 as output format and also as input format.

Regards,

Brijesh 

I read a image in  nv12 format and sent it to CSITX. It  keep reporting format errors. I don't know what the reason is?

App Init Done! 
App Create Graph Done! 
 11645.068562 s:  VX_ZONE_ERROR:[tivxAddKernelCsitxValidate:163] image format is invalid

This is my read image function and sent it to csitx.

readInputImageArr(inputFileName, 0, 1280, 720, obj->csitxObj.input_arr[0]);
status = app_create_graph_csitx(obj->graph, &obj->csitxObj, obj->csitxObj.input_arr[0]);

This is my csitx init and create function.

Hi Ling ling,

There are few issues i am seeing in the app_csitx_module.c file. Can you please correct them?

csitxObj->format = VX_DF_IMAGE_NV12; // NV12 image format is not supported in the CSITX.

csitxObj->cstix_params.instCfg[0U].numDataLanes         = 5U;//at max 4 data lanes are supported.

csitxObj->cstix_params.numCh                            = 0; // This should be set to atleast one.

Hi  Brijesh,

I have change it, and read a yuv422 formate picture(out.uyvy)  to csitx.

    vx_image  tx_frame_array_item = NULL;
    printf("Initializing Transmit yuv pictures...\n");
    tx_frame_array_item = (vx_image)vxGetObjectArrayItem(obj->csitxObj.input_arr[0], 0);
    if (tx_frame_array_item == NULL)
    {
        printf("%s[%d]vx_frame_array_item create failed\n", __FUNCTION__, __LINE__);
    }
    else
    {
        printf("vxGetObjectArrayItem success\n");
    }
    
	csitx_load_yuvfile(tx_frame_array_item,"output.uyvy");
	
    status = vxReleaseImage(&tx_frame_array_item);
    if(status != VX_SUCCESS)
    {
        printf("%s[%d] tx_frame_array_item Release failed\n", __FUNCTION__, __LINE__);
    }
        printf("Initializing YUV Buffers Done.\n");

When i run it, It get some failure.

Is there any configuration missing, thanks

Do you see any error from mcu2_0? It seems CREATE itself is failing, but there is no error log from MCU2_0. Have you enabled CSITX in the OpenVX header file?

HI,

Yes,I enable csitx.  It's  running well.

I have a few more questions to ask.

1.csitxObj->format = VX_DF_IMAGE_NV12; // NV12 image format is not supported in the CSITX.

What formats does CSITX support in total?

2.csitxObj->cstix_params.instCfg[0U].numDataLanes         = 5U;//at max 4 data lanes are supported.

csitxObj->cstix_params.numCh                            = 0; // This should be set to atleast one.

In the file:

video_io/kernels/video_io/host/vx_csitx_host.c  Shows that numDataLanes  is 5 and numch is 0;

What's the meaning of that?  

prms->instCfg[loopCnt].numDataLanes = 5u;

prms->numCh = 0u;

Thanks a lot

NV12 cannot be supported, because its not linear MIPI format. Most of the other standard formats are supported in the CSITX.

What's the meaning of that?  

NumDataLanes can be at max 4, because CSITX support upto 4 data lanes, we cannot set it to 5. The check in CSITX host is missing, but valid value is upto 4 only. 

Also the number of channels you are setting is 0, it should be atleast 1. This is the number of camera/virtual channels you want to send it out. It must not be 0, even though check is missing in the host file.
