@617505352 ,

Could you share more details such as the code snippet, and the version which you are using?

How can I achieve only pull streaming rawdata without render and no ui?

@617505352 , based on the code which you have shared, are you part of the beta testing group and recently updated from 5.14.5 to 5.15.2?

There are some updates to the interfaces when the versions updated. Did the compiler throw any error related to IAuthServiceEvent?

By default there is no UI for Meeting SDK Linux. If you are using the beta testing group’s sample app, the UI is only for demonstration and testing flow.

You will need to write something like this in your main method

1. initialise meeting SDK
2. authenticate meeting SDK

wait for authentication completed callback

1. Join Meeting
2. Start Raw Recording
3. Subscribe to user’s raw video and audio

@617505352 , the sample code which you are running right now, was provided to the beta testing group couple of months ago.

@617505352 ,

There is no more beta testing group.  
After getting this package, did you manually update the SDK to 5.15.12?

@617505352 please tag me in your response.  
did you overwrite your existing h folder with the ones from the downloaded h holders?  
The header files from your previous version needs to be deleted and replace with the new headers

@617505352 ,

I’ll try to explain how I’m getting this to work.

On my main thread, I have a method called AuthMeetingSDK.  
`m_pAuthService` is declared as `ZOOM_SDK_NAMESPACE::IAuthService* m_pAuthService;`  
There is a callback which I’ve declared called `OnAuthenticationComplete` on my main thread.

I’m using my own `AuthServiceEventListener` . I’ll share the .h & .cpp below

```auto
void OnAuthenticationComplete()

{

    if (isHeadless) {
    
    JoinMeeting(nullptr, nullptr, nullptr);
    
    }

}

```

```auto
void AuthMeetingSDK(Gtk::TextView* text_view)
{
	SDKError err(SDKError::SDKERR_SUCCESS);

	//create auth service
	if ((err = CreateAuthService(&m_pAuthService)) != SDKError::SDKERR_SUCCESS) {};
	std::cerr << "AuthService created." << std::endl;

	//Create a param to put in jwt token
	ZOOM_SDK_NAMESPACE::AuthContext param;

	//set the event listener for onauthenticationcompleted
	if ((err = m_pAuthService->SetEvent(new AuthServiceEventListener(&OnAuthenticationComplete))) != SDKError::SDKERR_SUCCESS) {};
	std::cout << "AuthServiceEventListener added." << std::endl;

	if (!token.size() == 0)
	{
		param.jwt_token = token.c_str();
		std::cerr << "AuthSDK:success " << std::endl;
	}

	//attempt to authenticate
	ZOOM_SDK_NAMESPACE::SDKError sdkErrorResult = m_pAuthService->SDKAuth(param);

	if (ZOOM_SDK_NAMESPACE::SDKERR_SUCCESS != sdkErrorResult)
	{
		if (text_view)
		{
			Glib::RefPtr<Gtk::TextBuffer> buffer = text_view->get_buffer();
			buffer->set_text("AuthSDK:error\n");
		}
		std::cerr << "AuthSDK:error " << std::endl;
	}
	else
	{
		if (text_view)
		{
			Glib::RefPtr<Gtk::TextBuffer> buffer = text_view->get_buffer();
			buffer->set_text("AuthSDK:success\n");
			std::cerr << "AuthSDK:success " << std::endl;
		}
	}
}

```

**AuthServiceEventListener.cpp**

```auto
#include "AuthServiceEventListener.h"
#include <iostream>

AuthServiceEventListener::AuthServiceEventListener(void(*onAuthSuccess)())
{
    
    onAuthSuccess_ = onAuthSuccess;
}

void AuthServiceEventListener::onAuthenticationReturn(ZOOM_SDK_NAMESPACE::AuthResult ret) {
    if (ret == ZOOM_SDK_NAMESPACE::AuthResult::AUTHRET_JWTTOKENWRONG)
    {
        // SDK Auth call failed because the JWT token is invalid.
       std::cout << "Auth failed: JWT Token is invalid." << std::endl;
    }
    else if (ret == ZOOM_SDK_NAMESPACE::AuthResult::AUTHRET_SUCCESS)
    {
        // SDK Authenticated successfully
        std::cout << "Auth succeeded: JWT." << std::endl;
          if (onAuthSuccess_) onAuthSuccess_();
    }
    else 
        std::cout << "Auth failed: " << ret << std::endl;
}

void AuthServiceEventListener::onLoginReturnWithReason(LOGINSTATUS ret, IAccountInfo* pAccountInfo, LoginFailReason reason)
{
    std::cout << "onLoginReturnWithReason: " << reason << std::endl;
  
}

void AuthServiceEventListener::onLogout()
{
    std::cout << "onLogout" << std::endl;
}

void AuthServiceEventListener::onZoomIdentityExpired()
{
    std::cout << "onZoomIdentityExpired" << std::endl;
}

void AuthServiceEventListener::onZoomAuthIdentityExpired()
{
    std::cout << "onZoomAuthIdentityExpired" << std::endl;
}

// void AuthServiceEventListener::onNotificationServiceStatus(SDKNotificationServiceStatus status)
// {
// std::cout << "onNotificationServiceStatus: " << status << std::endl;
// }

```

**AuthServiceEventListener.h**

```auto
#include "auth_service_interface.h"

{
	
    	 void (*onAuthSuccess_)();
