Using the IZoomSDKRenderer* videoHelper to record multiple participants

Video SDK Linux
3

Hi,
I’ve tried to declare 2 instances of IZoomSDKRenderer but it always generates only one yuv file.

here is the code, I started with explicitly declaring 2 IZoomSDKRenderer pointers:

uint32_t countUsers = getCountUsers();
IUserInfo *mySelfObj = getMyself();
std::string usersMap = "";
std::cout << "Attempt record " << countUsers << " users " << std::endl;

for(int i=0;i<countUsers;i++){
	std::cout << "User " << i << ": " << getUserObj(i) << " " << getUserObj(i)->GetUserID() << std::endl;
	if (mySelfObj->GetUserID() == getUserObj(i)->GetUserID()){
		std::cout << "This is me (the bot): " << i << std::endl;
	}else{

		std::cout << "attemptToStartRawRecording : subscribing" << std::endl;
		if(i == 0){
			std::cout << "TEST1 " << std::to_string(getUserObj(i)->GetUserID()) << std::endl;
			
			SDKError err = createRenderer(&videoHelperTest1, videoSource1);
			if (err != SDKERR_SUCCESS) {
				std::cout << "Error occurred" << std::endl;
				// Handle error
			}
			videoHelperTest1->setRawDataResolution(ZoomSDKResolution_720P);
			videoHelperTest1->subscribe(getUserObj(i)->GetUserID(), RAW_DATA_TYPE_VIDEO);
		}else{

			std::cout << "TEST2 " << std::to_string(getUserObj(i)->GetUserID()) << std::endl;
		
			SDKError err = createRenderer(&videoHelperTest2, videoSource2);
			if (err != SDKERR_SUCCESS) {
				std::cout << "Error occurred" << std::endl;
				// Handle error
			}
			videoHelperTest2->setRawDataResolution(ZoomSDKResolution_720P);
			videoHelperTest2->subscribe(getUserObj(i)->GetUserID(), RAW_DATA_TYPE_VIDEO);
		}

	}
}

Initizated in the beginning:


ZoomSDKRenderer* videoSource1 = new ZoomSDKRenderer();
ZoomSDKRenderer* videoSource2 = new ZoomSDKRenderer();
IZoomSDKRenderer* videoHelperTest1;
IZoomSDKRenderer* videoHelperTest2;

And I’m identifying the stream participant by int number = data->GetSourceID(); like this:

void ZoomSDKRenderer::onRawDataFrameReceived(YUVRawDataI420* data)
{
	std::cout << "sourceID." << data->GetSourceID() << std::endl;
}

This is always prints the same single UserId of one participant instead of getting fired for both the participants. (2 real participants and the bot is in the meeting).

@chunsiong.zoom Do you have any idea why is it happening?

UPDATE:
I saw your comment here: Cannot obtain data for more than 5 people using raw data - #2 by chunsiong.zoom Is there any way to get more then 4 participants raw data?
