TDA4VM: Problems encountered when converting RGBX to NV12 using m2m nodes

yang yang

Part Number: TDA4VM

Tool/software:

Hello,

I want to convert the output of srv to NV12, and then go through scaler nodes, mosaic nodes, and display nodes. I encountered some problems during this process and hope to get your help.

I did the following test. SDK:08-04

1. capture(yuv422)->ldc(NV12)->srv(RGBX)->m2m(NV12)->display

The screen is as shown in Figure 1. When I delete vxReplicateNode() in "app_fmt_cnv_module.c" obtained from [FAQ] TDA4VM: How to use DSS M2M for format conversion? - Processors forum - Processors - TI E2E support forums, the screen can output normally.

2. capture(yuv422)->ldc(NV12)->srv(RGBX)->m2m(NV12)->scaler->mosaic->display

When deleting vxReplicateNode() in "app_fmt_cnv_module.c",

some of the logs are as follows.

the first error VX_ZONE_ERROR:[tivxSetNodeParameterNumBufByIndex:2325] Invalid parameters in code:

if (status == VX_SUCCESS) {
status = tivxSetNodeParameterNumBufByIndex(obj->fmtConvObj.node, 1, APP_BUFFER_Q_DEPTH);
status = tivxSetNodeParameterNumBufByIndex(obj->fmtConvObj.node, 2, APP_BUFFER_Q_DEPTH);
} .

My graph create code as:

if(obj->sensorObj.enable_ldc == 1)
    {
        vx_object_array ldc_in_arr;
        if(1 == obj->enable_viss)

        }
        // obj->imgMosaicObj.input_arr[idx++] = obj->ldcObj.output_arr;
    }

    if(obj->enable_srv == 1 && status == VX_SUCCESS)
    {
        status = app_create_graph_srv(obj->context, obj->graph, &obj->srvObj, obj->ldcObj.output_arr);

        APP_PRINTF("scaler graph done!\n");
    }

    vx_image display_in_image;
    if(obj->enable_mosaic == 1)
    {
        if(obj->enable_scaler == 1)
        {

            APP_PRINTF("enable_mosaic and enable_scaler!\n");
        }
        else
        {
            obj->imgMosaicObj.input_arr[idx++] = obj->fmtConvObj.arr;
        }

        obj->imgMosaicObj.num_inputs = idx;

        if(status == VX_SUCCESS)
        {
            status = app_create_graph_img_mosaic(obj->graph, &obj->imgMosaicObj, NULL);
            APP_PRINTF("Img Mosaic graph done!\n");
        }
        display_in_image = obj->imgMosaicObj.output_image[0];
    }
    else{

    }


    if(status == VX_SUCCESS)

            status = app_create_graph_display(obj->graph, &obj->displayObj, display_in_image);
        }
        else

            status = app_create_graph_display(obj->graph, &obj->displayObj, display_in_image);
        }
        APP_PRINTF("Display graph done!\n");
    }

Next, I delete 'status = tivxSetNodeParameterNumBufByIndex(obj->fmtConvObj.node, 1, APP_BUFFER_Q_DEPTH);' ,the first error VX_ZONE_ERROR:[tivxSetNodeParameterNumBufByIndex:2325] Invalid parameters has disappeared while the other errors still exist. The screen is as shown in Figure 2.

Then I try to add vxReplicateNode() in "app_fmt_cnv_module.c", the error seems to have disappeared, but there is still an issue with the display.

Can M2M be considered as a single channel input when accepting the output of SRV? When do I need to use vxReplicateNode()? Why set node parameters for m2m input? How can I modify it? Can you give me some suggestions?

Thanks.

Hi,

Yes, DSS M2M node can support single channel input and when it is working in single channel input mode, please dont call vxReplicateNode for this node. Also when you are not calling vxReplicateNode, please use separate vx_image as output image, instead of an instance of object array. This should solve both of the issues.

Regards,

Thank you for your reply.

You mean to change the output of m2m to vx_image type but the input of scaler is vx_object_array, please how to convert vx_image to vx_object_array?

I add codes between m2m node and asacler node, shown in the first txt. I know this is wrong. And only shows pink on the screen , shown in fig.1. How do I change it and where do I place it?

static vx_status MapImageToArray(vx_context context, vx_object_array *array, vx_image in_img)
{
    vx_status status = VX_SUCCESS;
    vx_rectangle_t rect;
    vx_imagepatch_addressing_t in_addr, out_addr;
    vx_map_id map_id_in;
    vx_map_id map_id_out;

    void * in_ptr, *out_ptr;
    vx_uint32  img_width;
    vx_uint32  img_height;
    vx_uint32  y;
    vx_image   out_img;
    out_img = (vx_image)vxGetObjectArrayItem((*array), 0);

    vxQueryImage(out_img, VX_IMAGE_WIDTH, &img_width, sizeof(vx_uint32));
    vxQueryImage(out_img, VX_IMAGE_HEIGHT, &img_height, sizeof(vx_uint32));


    rect.start_x = 0;
    rect.start_y = 0;
    rect.end_x = img_width;
    rect.end_y = img_height;
    status = vxMapImagePatch(in_img,&rect,0,&map_id_in,&in_addr,&in_ptr,VX_READ_ONLY,VX_MEMORY_TYPE_HOST,VX_NOGAP_X);
    if(status == VX_SUCCESS)
    {
        status = vxMapImagePatch(out_img,&rect,0,&map_id_out,&out_addr,&out_ptr,VX_WRITE_ONLY,VX_MEMORY_TYPE_HOST,VX_NOGAP_X);
    }
    printf("in_addr.dim_y, out_addr.dim_y, in_addr.stride_y:%d, %d, %d\n",in_addr.dim_y, out_addr.dim_y, in_addr.stride_y);
    if(status == VX_SUCCESS)
    {
        for(y = 0; y < in_addr.dim_y; y++)
        {
            void *in_ptr_y = in_ptr + y * in_addr.stride_y;
            void *out_ptr_y = out_ptr + y * out_addr.stride_y;

            memcpy(out_ptr_y, in_ptr_y, in_addr.stride_y);
        }
        printf("COPY DONE\n");
    }
    status = vxUnmapImagePatch(in_img, map_id_in);
    if(status == VX_SUCCESS)
    {
        status = vxUnmapImagePatch(out_img, map_id_out);
    }
    return status;

}

Also, for a scaler node, what if the input is also single channel? I found that the scaler node of the demo app_tidi_od receives single channel data with two outputs, vxRepliacate() is called.

Here's the code for my m2m node creation as well as graph creation.
Thank you.

vx_status app_create_graph_fmt_conv(vx_graph graph, FmtConvObj *obj, vx_image input)
{
    vx_status status = VX_SUCCESS;
