	AInConfigBPLibrary();

protected:

#include "InConfigBPLibrary.h"

// Sets default values
AInConfigBPLibrary::AInConfigBPLibrary()
{
 	// Set this actor to call Tick() every frame.  You can turn this off to improve performance if you don't need it.
	PrimaryActorTick.bCanEverTick = true;

}

// Called when the game starts or when spawned
void AInConfigBPLibrary::BeginPlay()
{
	Super::BeginPlay();

}

// Called every frame
void AInConfigBPLibrary::Tick(float DeltaTime)
{
	Super::Tick(DeltaTime);

}

void AInConfigBPLibrary::GetConfigNdiInfo(TArray<FString>& configNDIInfo)
{
	FString ConfigPath = FPaths::ConvertRelativePathToFull(FPaths::ProjectDir()) + "Config/config.ini";
	FString sourcename;
	GConfig->GetString(TEXT("NDI"), TEXT("sourcename"), sourcename, ConfigPath);
	configNDIInfo.Add(sourcename);
	FString machinename;
	GConfig->GetString(TEXT("NDI"), TEXT("machinename"), machinename, ConfigPath);
	configNDIInfo.Add(machinename);
	FString streamname;
	GConfig->GetString(TEXT("NDI"), TEXT("streamname"), streamname, ConfigPath);
	configNDIInfo.Add(streamname);
}

二、配置ini文件

在项目目录下创建目录及文件 Config/config.ini

添加源名、机器名和流名：

1
2
3
4
[NDI]
sourcename=FORMEASY (HDD1)
machinename=FORMEASY
streamname=HDD1

注：注意:sourcename的设备名和流名之间有空格

三、NDIIO插件复制

将UE5中的plugin下NDIIO插件目录复制到项目plugin下

四、添加关卡蓝图方法

按照下图，在EventBeginPlay后添加NDI配置:
