Hello,

I’m testing with current last version of Meeting SDK: 5.9.3.3191

I’m trying to read Raw data according to [https://marketplace.zoom.us/docs/sdk/native-sdks/windows/raw-data](https://marketplace.zoom.us/docs/sdk/native-sdks/windows/raw-data)  
There’s some example about implementing that? I’m having troubles on this part:

> 1. Once the recording has started, you will need to pass the `IZoomRendererDelegate` into the `createRenderer` method in `zoom_rawdata_api.h` .

I don’t really know how to pass IZoomRendererDelegate, there’s any instance of it? Because when I create it it has null value.

Thanks

Hi Pablo,

You should create a new class and inherit it from _ZOOM\_SDK\_NAMESPACE::IZoomSDKRendererDelegate_, then implement virtual functions

| | // Inherited via IZoomSDKRendererDelegate |
| --- | --- |
| | virtual void onRendererBeDestroyed() override; |
| | virtual void onRawDataFrameReceived(YUVRawDataI420\* data) override; |
| | virtual void onRawDataStatusChanged(RawDataStatus status) override; |

Then pass an instance of the above class to _createRenderer_ function.

ZOOM\_SDK\_NAMESPACE::SDKError error = ZOOM\_SDK\_NAMESPACE::createRenderer(&\_video\_renderer, this);

&\_video\_renderer is a reference pointer, you can call methods from this once render is successfully created. Then subscribe to streams accordingly

\_video\_renderer-\>subscribe(user\_id, ZOOMSDK::ZoomSDKRawDataType::RAW\_DATA\_TYPE\_VIDEO);
