**Description**  
I have tried to access the raw data using the [tutorial](https://developers.zoom.us/docs/sdk/native-sdks/windows/raw-data/), but nothing happens when the render is created

**Which Windows Meeting SDK version?**  
zoom-sdk-windows-5.13.5.12103

**To Reproduce(If applicable)**

1. Do steps 1 to 2 from the tutorial
2. For the 3rt step I call a pointer object in CustomizedUIRecordMgr.h

```auto
#pragma once

#include "stdafx.h"
#include "sdk_util.h"
#include <rawdata/rawdata_renderer_interface.h>

class CustomizedUIRecordMgr : 
	public ZOOM_SDK_NAMESPACE::IMeetingRecordingCtrlEvent
{

public:
	static CustomizedUIRecordMgr* GetInstance();
	void GetRecordController();
	bool StartRecording(time_t& startTimestamp);
	bool StopRecording(time_t& stopTimestamp);
	bool StartCloudRecording();
	bool StopCloudRecording();

	bool StartRawRecording();
	bool StopRawRecording();

	bool CanTheUserStartLocalRecording(unsigned int userid);
	bool CanTheUserStartCloudRecording(unsigned int userid);
	bool CanIStartLocalRecording();
	bool CanIStartCloudRecording();
	bool CanIChangeOthersRecordingPermission();
	bool DoesTheUserSupportLocalRecording(unsigned int userid);

	bool AllowLocalRecording(unsigned int userid);
	bool DisAllowLocalRecording(unsigned int userid);
	
	virtual void onRecording2MP4Done(bool bsuccess, int iResult, const wchar_t* szPath);
	virtual void onRecording2MP4Processing(int iPercentage);
	virtual void onRecordingStatus(ZOOM_SDK_NAMESPACE::RecordingStatus status);
	virtual void onCloudRecordingStatus(ZOOM_SDK_NAMESPACE::RecordingStatus status);
	virtual void onRecordPriviligeChanged(bool bCanRec);
	virtual void onCustomizedLocalRecordingSourceNotification(ZOOM_SDK_NAMESPACE::ICustomizedLocalRecordingLayoutHelper* layout_helper);
	virtual void onLocalRecordingPrivilegeRequestStatus(ZOOM_SDK_NAMESPACE::RequestLocalRecordingStatus status) {}
	virtual void onLocalRecordingPrivilegeRequested(ZOOM_SDK_NAMESPACE::IRequestLocalRecordingPrivilegeHandler* handler) {}
private:
	CustomizedUIRecordMgr();
	~CustomizedUIRecordMgr();

private:
	static CustomizedUIRecordMgr* s_recordMgrObj;
	time_t m_rcdStartTime; 
	ZOOM_SDK_NAMESPACE::IMeetingRecordingController* m_pRecordController;
	ZOOM_SDK_NAMESPACE::IZoomSDKRenderer* m_pRawRenderController;
	ZOOM_SDK_NAMESPACE::IZoomSDKRendererDelegate* m_pRawDataRenderer;
};

```

1. Implement a new method in CustomizedUIRecordMgr.cpp

```auto
bool CustomizedUIRecordMgr::StartRawRecording()
{
	GetRecordController();

	if (!m_pRecordController){
		return false;
	}

	ZOOM_SDK_NAMESPACE::SDKError rtn;
	rtn = m_pRecordController->StartRawRecording();
	if (rtn == ZOOM_SDK_NAMESPACE::SDKERR_SUCCESS){
		::MessageBox(NULL, _T("Taking raw video sucess"), _T("winsdk demo"), MB_OK);
		ZOOM_SDK_NAMESPACE::createRenderer(&m_pRawRenderController, m_pRawDataRenderer);
		//m_pRawDataRenderer->
		return true;
	}else {
		return false;
	}
}

```

1. When pass in sucess, the event “onRawDataFrameReceived” is not triggered

**Troubleshooting Routes**  
…

**Device (please complete the following information):**

- Device: Hp Probook 440GB
- OS: . Windows 10 Pro

**Additional context**  
Each user have to subcribe to any event to acess to raw data?
