libargus调整ISP详细代码

以下是使用libargus调整ISP参数的示例代码：

#include <Argus/Argus.h>
#include <EGLStream/EGLStream.h>
#include <unistd.h>

using namespace Argus;
using namespace EGLStream;

int main(int argc, char** argv)
{
    // 创建CaptureSession
    UniqueObj<CameraProvider> cameraProvider(CameraProvider::create());
    ICameraProvider* iCameraProvider = interface_cast<ICameraProvider>(cameraProvider);
    if (!iCameraProvider)
    {
        printf("Failed to create CameraProvider.\n");
        return -1;
    }

    std::vector<CameraDevice*> cameraDevices;
    if (iCameraProvider->getCameraDevices(&cameraDevices) != STATUS_OK)
    {
        printf("Failed to get CameraDevices.\n");
        return -1;
    }

    CameraDevice* cameraDevice = cameraDevices[0];

    UniqueObj<CaptureSession> captureSession(iCameraProvider->createCaptureSession(cameraDevice));
    ICaptureSession* iCaptureSession = interface_cast<ICaptureSession>(captureSession);
    if (!iCaptureSession)
    {
        printf("Failed to create CaptureSession.\n");
        return -1;
    }

    // 设置输出流
    UniqueObj<OutputStreamSettings> streamSettings(iCaptureSession->createOutputStreamSettings(STREAM_TYPE_EGL));
    IEGLStreamSettings* iEGLStreamSettings = interface_cast<IEGLStreamSettings>(streamSettings);
    if (!iEGLStreamSettings)
    {
        printf("Failed to create OutputStreamSettings.\n");
        return -1;
    }

    iEGLStreamSettings->setPixelFormat(PIXEL_FMT_YCbCr_420_888);
    iEGLStreamSettings->setResolution(Size2D<uint32_t>(1920, 1080)); // 设置分辨率
    iEGLStreamSettings->setBufferCount(4);

    UniqueObj<OutputStream> outputStream(iCaptureSession->createOutputStream(streamSettings.get()));
    IEGLOutputStream* iEGLOutputStream = interface_cast<IEGLOutputStream>(outputStream);
    if (!iEGLOutputStream)
    {
        printf("Failed to create OutputStream.\n");
        return -1;
    }

    // 创建请求
    UniqueObj<Request> request(iCaptureSession->createRequest(CAPTURE_INTENT_PREVIEW));
    IRequest* iRequest = interface_cast<IRequest>(request);
    if (!iRequest)
    {
        printf("Failed to create Request.\n");
        return -1;
    }

    ISourceSettings* iSourceSettings = interface_cast<ISourceSettings>(iRequest->getSourceSettings());
    if (!iSourceSettings)
    {
        printf("Failed to get SourceSettings.\n");
        return -1;
    }

    iSourceSettings->setSensorMode(0); // 设置相机传感器模式

    // 调整ISP参数
    IAutoControlSettings* iAutoControlSettings = interface_cast<IAutoControlSettings>(iRequest->getAutoControlSettings());
    if (!iAutoControlSettings)
    {
        printf("Failed to get AutoControlSettings.\n");
        return -1;
    }

    iAutoControlSettings->setAeTargetFpsRange(Range<float>(30.0f, 30.0f)); // 设置帧率
    iAutoControlSettings->setAeAntibandingMode(ANTIBANDING_MODE_AUTO); // 设置抗闪烁模式
    iAutoControlSettings->setAeLock(true); // 锁定自动曝光

    // 开始捕获
    iCaptureSession->repeat(request.get());
    usleep(5000000); // 等待5秒钟
    iCaptureSession->stopRepeat();

    return 0;
}

这段代码演示了如何使用libargus调整ISP参数，包括设置分辨率、帧率、抗闪烁模式等。注意，在设置自动曝光时需要先将自动曝光锁定，否则设置不会生效。
