嗨、团队：
我正在使用 SDK 08_02_00_05 (Linux+RTOS)。
在测试应用程序时、我将看到以下错误日志。

附加我的 app_create_graph 函数。
static vx_status app_create_graph(AppObj *obj)
{
vx_status status = VX_SUCCESS;
vx_char output_file_name[APP_MAX_FILE_PATH];
//vx_graph_parameter_queue_params_t graph_parameters_queue_params_list[2];
//vx_int32 graph_parameter_index;
obj->graph = vxCreateGraph(obj->context);
status = vxGetStatus((vx_reference)obj->graph);
if(status == VX_SUCCESS)
{
status = vxSetReferenceName((vx_reference)obj->graph, "OpenVxGraph");
}
if(status == VX_SUCCESS)
{
status = app_create_graph_res_resize(obj->graph, &obj->resResizeObj, obj->input.arr[0]);
APP_PRINTF(" app_create_graph_res_resize graph done!\n");
}
if(status == VX_SUCCESS)
{
status = app_create_graph_color_conv_RGB_NV12(obj->graph, &obj->colorConvRGBNV12Obj, obj->resResizeObj.output_image_arr);
APP_PRINTF(" app_create_graph_color_conv_RGB_NV12 graph done!\n");
}
vx_image src_image1 = (vx_image)vxGetObjectArrayItem(obj->colorConvRGBNV12Obj.dst_image_arr, 0);
snprintf(output_file_name, APP_MAX_FILE_PATH, "%s/cc_output.bmp", obj->output_file_path);
tivx_utils_save_vximage_to_bmpfile(output_file_name, src_image1);
if(status == VX_SUCCESS)
{
status = app_create_graph_ldc(obj->graph, &obj->ldcObj, obj->colorConvRGBNV12Obj.dst_image_arr);
APP_PRINTF("LDC graph done!\n");
}
if(status == VX_SUCCESS)
{
status = app_create_graph_scaler(obj->context, obj->graph, &obj->scalerObj, obj->ldcObj.output_arr);
}
if(status == VX_SUCCESS)
{
status = app_create_graph_pre_proc(obj->graph, &obj->preProcObj, obj->scalerObj.output[0].arr);
}
if(status == VX_SUCCESS)
{
status = app_create_graph_tidl(obj->context, obj->graph, &obj->tidlObj, obj->preProcObj.output_tensor_arr);
APP_PRINTF("TIDL Create Done! \n");
}
if(status == VX_SUCCESS)
{
status = app_rci_create_graph_postproc(obj->graph, &obj->rcipostprocObj, obj->tidlObj.output_tensor_arr);
APP_PRINTF("RCI Create Postproc Done!\n");
}
return status;
}
当我转储 obj->colorconvRGBNV12Obj.dst_image_arr 时 、输出不是预期的、但并非 NULL。 将转储装置连接在下方。
但是、将相同的信息传递给 下一个节点的 APP_CREATE_GRAPH_LDC 函数时、我将面临错误。
LDC 中的输出图像为 NULL
62.038711 s：vx_zone_error：[vxSetParameterByIndex：228]提供的值实际上不是参考
62.038721 s：vx_zone_error：[vxSetParameterByIndex：305]指定：parameter[7] type：00000000 =>(nil)
62.038728 s：vx_zone_error：[vxSetParameterByIndex：307]必需：parameter[7] dir：1 type：0000080f
62.038739 s：vx_zone_error：[ownReleaseReferenceInt：307]引用无效
62.038746 s：vx_zone_error：[vxGetStatus：713]参考为 NULL
这种行为的原因可能是什么？ 如何解决此问题？
此致、
