IVideoRecordingSystem

可以实现在Game下的录制

#include "VideoRecordingSystem.h"
#include "PlatformFeatures.h"

//初始化
IVideoRecordingSystem* VideoRecordSystem =  IPlatformFeaturesModule::Get().GetVideoRecordingSystem();
VideoRecordSystem->EnableRecording(true);
FVideoRecordingParameters param;
param.RecordingLengthSeconds = 6000;//设置的最大录制时间，不会录制超过的时间

 //开始录制
VideoRecordSystem->NewRecording(TEXT("MyVideo"), param);
VideoRecordSystem->StartRecording();

//结束录制
IVideoRecordingSystem* VideoRecordSystem =  IPlatformFeaturesModule::Get().GetVideoRecordingSystem();
VideoRecordSystem->FinalizeRecording(true, FText::FromString("Hello"),  FText::FromString("World"));
      

ISequenceRecorder

在Editor下使用，可以录制一段Sequence，保存在固定的文件夹下。

#include "ISequenceRecorder.h"

//开始录制
ISequenceRecorder& Recorder =  FModuleManager::LoadModuleChecked<ISequenceRecorder>("SequenceRecorder");
Recorder.StartRecording(this, "/Game/Sequence", "RecordedSequence");

//停止录制
ISequenceRecorder& Recorder =  FModuleManager::LoadModuleChecked<ISequenceRecorder>("SequenceRecorder");
Recorder.StopRecording();

创建蓝图节点

VideoRecordBlueprint.h

#pragma once
#include "CoreMinimal.h"
#include "Kismet/BlueprintFunctionLibrary.h"
#include "VideoRecordBlueprint.generated.h"
UCLASS(Blueprintable, BlueprintType, meta = (DisplayName = "Record a Video"))
class VIDEORECORD_API UVideoRecordBueprint : public UBlueprintFunctionLibrary
{
    GENERATED_BODY()
public:
    //开始录制
    UFUNCTION(BlueprintCallable, Category = "VideoRecording")
    static bool StartRecording(const FString& Name);
    //停止录制
    UFUNCTION(BlueprintCallable, Category = "VideoRecording")
    static bool StopRecording();
};

VideoRecordBlueprint.cpp

#include "VideoRecordBlueprint.h"
#include "VideoRecordingSystem.h"
#include "PlatformFeatures.h"
bool UVideoRecordBueprint::StartRecording(const FString& Name)
{
    IVideoRecordingSystem* VideoRecordSystem = IPlatformFeaturesModule::Get().GetVideoRecordingSystem();
    VideoRecordSystem->EnableRecording(true);
    FVideoRecordingParameters param;
    param.RecordingLengthSeconds = 6000;
    VideoRecordSystem->NewRecording(*Name, param);
    VideoRecordSystem->StartRecording();
    return true;
}
bool UVideoRecordBueprint::StopRecording()
{
    IVideoRecordingSystem* VideoRecordSystem = IPlatformFeaturesModule::Get().GetVideoRecordingSystem();
    VideoRecordSystem->FinalizeRecording(true, FText::FromString("Hello"), FText::FromString("World"));
    return true;
}

在关卡中的调用：

V按下M键实现播放一段Sequence，结束后会在项目文件的Saved\VideoCaptures下生成对应MP4文件。
