SOLVED

**

Thanks to the Rob for bringing light to my problem.

Create a global var on component unit fDict Implement 3 methods, one to add, one to remove and one to retrive; making the main class create , clear and destroy the global var to avoid memory leaks making the connectin function of TDispositivo to feed the fDict making the callback to retrive and move on. making the disconnect function of TDispositivo to remove the reference in fDict keeping it updated

**

EDIT

**

I found my crash error, i´m implementing the dll inside a component class and try to declare the callback procedures inside the class using

TSnapRev = procedure(XXXXX) of object stdcall;

... private procedure callbacksnapshot(XXXXX); stdcall; ...

CLIENT_SetSnapRevCallBack(callbackSnapshot,FSDKUSer);

the callbacksnapshot was triggered but raising a accesse violation after.

O realize the order of variables returned was always misplaced, then i change my approuch moving the callbacksnapshot procedure out of the class and changing type declaration like this:

Type TSnapRev = procedure(XXXXX); stdcall;

TDispositivo = class private end;

procedure callbacksnapshot(XXXXX); stdcall;

... CLIENT_SetSnapRevCallBack(@callbackSnapshot,FSDKUSer); ...

now the callback triggeing, the order of variables are right and no access violation after, BUT, i need to invoke some functions (events, etc) from my TDispositivo instance or from the owner of TDispositivo instance, in a outside procedure i can´t.

How can i do this into my class ?

i had tryed declare a variable FSDKSnap : TRevSap (when TRevSap is a type of object) but got the same erros or miplaced vars and access violations

Keep working on my Dahua dll convertion to Delphi. Now i'm stuck in a callback, actually in a definition of the type used.

There is the cpp code in header

I would like to redirect two POST request form Dahua ANPR camera to one script in Microsoft IIS. I would like to redirect POST request from "http://localhost/NotificationInfo/KeepAlive" and "http://localhost/NotificationInfo/TollgateInfo" to "http://localhost/anpr/". I have created rules in the main configuration file "C:\inetpub\wwwroot\web.config":

Now I'm trying to get the picture from my Dahua Terminal, and the code becomes a little trick.

In C++ sample code, I have:

Sorry about my Yoda English, i will try my best.

I'm trying to use a Dahua SDK .dlls in my Delphi App but i can´t undertand how to do some convertions from one dll function.

To give some context to my problem, i will try to explain what i´m trying to do.

I need to call a find function from a dll to list all cardusers from a terminal, so the SDK provide a DLL with C++ header and a sample app to explain how to use it on Visual c++;

My first problem is i´m using Delphi and i need to translate the header from DLL and convert the C++ codes to Delphi;

The Find function from DLL is described bellow:

I am attempting to add a button to the customer's page to add a new device but when rendering the form I would like to pass the customer's name as an initial value.

This was my personal Christmas project to make my work projects a bit more centralized in 2021. Im almost over the finish line but I've hit this bump. Any help would be appreciated. Thanks.

I have two models in separate apps.

i have this script in python:

I'm trying to connect to an IP Camera (Dahua) using OpenCV and Python using an RTSP URI. I added a sample code below (with the username, password and ip provided in separate variables), which results in [rtsp @ 0x55cc3715c600] method OPTIONS failed: 401 Unauthorized. Using VLC, I'm able to connect, however only after entering the password in a separate dialog even though the password was already provided in the URI.

How should I continue?

PROBLEM:

I have a number of test cameras that I'm using in development of a Cocoa ONVIF driver. I have AXIS, Dahua and Hikvision (so far -more will be coming).

All of the cameras claim conformance to Profile S and Profile G.

The AXIS cameras are the only ones that are behaving as expected.

Most can return RTSP image data if I send a direct URI to them (which, I see, is how most "ONVIF" apps seem to work).

What I am trying to do, is use the "proper channels" to access these devices.

That means running the MANDATORY GetProfiles query, like so:

I'm new to Linux environment. I'm trying to run my C++ files on Codelite and its giving me error which just won't go. I have a DLL folder of my Dahua SDK. It contains shared .so libraries. I'm getting this error since last 2 days and can't run my project!

./Dahuatest1: error while loading shared libraries: libdhnetsdk.so: cannot open shared object file: No such file or directory

I already tried:

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/tarak/Documents/General_NetSDK_Eng_Linux64_IS_V3.48.1.R.170623/NetSDK_Eng_Bin/Demo_Src/DLL

export LD_LIBRARY_PATH

ldconfig

which also includes my DLL folder. But still get the same error.

I also tried to change my path to my folder in ~/.bashrc:

export $PATH=$PATH:/home/tarak/Documents/General_NetSDK_Eng_Linux64_IS_V3.48.1.R.170623/NetSDK_Eng_Bin/Demo_Src/DLL

this too failed!

What should I do to get the output??

In codelite I've set Linker search path as my DLL folder. And compiler 'Include Path' also as my DLL folder

Here's a screenshot of my folder: Project file
