0、前文回顾

 前文已经简单说明CameraHalService服务、Serarch Sensor、open的过程 的动作。

在这期间，CameraService、CameraProviderManager、CameraHalService、CamereaProvider、CameraDeviceManager

简单回顾下：

1、CameraService

  frameworks/av/services/camera/libcameraservice/CameraService.cpp

08-26 11:30:28.450083  4144  4144 I CameraService: CameraService started(pid=4144)

/*这里打印的“开始延迟”是对HAL从开始运行所需时间的估计进程创建，将自己注册为HAL。实际的启动时间可能更长

因为进程可能还没有加入线程池，所以它可能还没有准备好加入处理事务*/

2、CameraHalService

 强力建议熟读Camera3.h   Startup and general expected operation sequence

https://www.androidos.net.cn/android/10.0.0_r6/xref/hardware/libhardware/include/hardware/camera3.h

1、camera configureStreams 流程

 1.1 相机api简述

      as we all know Android Camera API的 步骤

  （1）、监听和枚举相机设备  

    get_number_of_cameras、get_camera_characteristic

  （2）、打开设备并连接监听器

    connect、open

  （3）、配置目标使用情形的输出（如static 、capture、video等）

     configure_stream

    (4）、为目标使用情形创建请求  （5）捕获/重复请求和连拍

    process_capture_request

    (6) 、接受结果metadata和图片数据

    proces_capture_result

    (7)、切换使用情形时，返回第三步

1.2 原文阅读

    * 4. The framework calls camera3_device_t->ops->configure_streams() with a list * of input/output streams to the HAL device.

简单翻译-->

framework调用结构体camera_device方法ops调用结构体camera3_device_ops的configure_streams方法配流，camera3_device_t-> ops-> configure_streams（），并把input stream&output stream 的列表作为参数送到Hal层。

1.3 结构体

 hardware/libhardware/include/hardware/camera3.h

camera3_device_ops_t 映射函数指针操作： hardware/libhardware/modules/camera/3_0/Camera.cpp

1.4 代码流程

hardware/interfaces/camera/device/3.2/default/CameraDeviceSession.cpp

Return<void> CameraDeviceSession::configureStreams(
        const StreamConfiguration& requestedConfiguration,
        ICameraDeviceSession::configureStreams_cb _hidl_cb)  {
    Status status = initStatus();
    HalStreamConfiguration outStreams;

    ATRACE_BEGIN("camera3->configure_streams");
    status_t ret = mDevice->ops->configure_streams(mDevice, &stream_list);
    ATRACE_END();
}

frameworks/av/services/camera/libcameraservice/device3/Camera3Device.cpp

status_t Camera3Device::configureStreamsLocked(int operatingMode,
        const CameraMetadata& sessionParams, bool notifyRequestThread) {
   

    //配流开始log
    ALOGV("%s: Camera %s: Starting stream configuration", __FUNCTION__, mId.string());

  略...

    //创建buffer

    const camera_metadata_t *sessionBuffer= sessionParams.getAndLock();
    res = mInterface->configureStreams(sessionBuffer, &config, bufferSizes);

   //这里还有重新配流的代码，省略

  // Update device state
    const camera_metadata_t *newSessionParams = sessionParams.getAndLock();
       省略部分代码

    ALOGV("%s: Camera %s: Stream configuration complete", __FUNCTION__, mId.string());

    // tear down the deleted streams after configure streams.
    mDeletedStreams.clear();

    return OK;
}

status_t Camera3Device::HalInterface::configureStreams(const camera_metadata_t *sessionParams,
        camera3_stream_configuration *config, const std::vector<uint32_t>& bufferSizes) {
    ATRACE_NAME("CameraHal::configureStreams");
 略...
        auto err = mHidlSession_3_4->configureStreams_3_4(
                requestedConfiguration3_4, configStream34Cb);
   略...

    return res;
}

vendor/mediatek/proprietary/hardware/mtkcam3/main/hal/device/3.x/device/CameraDevice3SessionImpl.cpp

//V3_4
Return<void>
ThisNamespace::
configureStreams_3_3(const V3_2::StreamConfiguration& requestedConfiguration, configureStreams_3_3_cb _hidl_cb)
{ 省略部分代码
            err = onConfigureStreamsLocked(requestedConfiguration, halStreamConfiguration);

}

vendor/mediatek/proprietary/hardware/mtkcam3/main/hal/device/3.x/device/CameraDevice3SessionImpl.cpp

auto
ThisNamespace::
onConfigureStreamsLocked(
    const WrappedStreamConfiguration& requestedConfiguration,
    WrappedHalStreamConfiguration& halConfiguration
) -> ::android::status_t
{  
    IAppStreamManager::ConfigAppStreams appStreams;
    auto pAppStreamManager= getSafeAppStreamManager();

    err = pAppStreamManager->beginConfigureStreams(requestedConfiguration, halConfiguration, appStreams);
        auto pPipelineModel= getSafePipelineModel();      
        err = pPipelineModel->configure(pParams);   //配置pipeline
    err = pAppStreamManager->endConfigureStreams(halConfiguration);
}

vendor/mediatek/proprietary/hardware/mtkcam3/main/hal/device/3.x/app/AppStreamMgr.cpp

auto
AppStreamMgr::
beginConfigureStreams(
    const V3_5::StreamConfiguration& requestedConfiguration,
    V3_4::HalStreamConfiguration& halConfiguration,
    ConfigAppStreams& rStreams
)   -> int
{
    auto err = mConfigHandler->beginConfigureStreams(requestedConfiguration, halConfiguration, rStreams);
}

vendor/mediatek/proprietary/hardware/mtkcam/main/hal/device/3.x/app/AppStreamMgr.ConfigHandler.cpp

简述下这里面干了些啥事

（1）、检测stream

（2）、设置OperationMode

（3）、生成MetaStreamInfo，并把前者加到Stream中

auto
ThisNamespace::
beginConfigureStreams(
    const V3_5::StreamConfiguration& requestedConfiguration,
    V3_4::HalStreamConfiguration& halConfiguration,
    ConfigAppStreams& rStreams
)   -> int
{   
                rStreams.vMinFrameDuration.add(  //这块为上层下发的流配置格式
                    pStreamInfo->getStreamId(),
                    mEntryMinDuration.itemAt(j + 3, Type2Type<MINT64>())
                );
                rStreams.vStallFrameDuration.add(  //这块为上层下发的流配置格式
                    pStreamInfo->getStreamId(),
                    mEntryStallDuration.itemAt(j + 3, Type2Type<MINT64>())
                );
                MY_LOGI("[addFrameDuration] format:%" PRId64 " size:%" PRId64 "x%" PRId64 " min_duration:%" PRId64 ", stall_duration:%" PRId64 ,
                    mEntryMinDuration.itemAt(j, Type2Type<MINT64>()),
                    mEntryMinDuration.itemAt(j + 1, Type2Type<MINT64>()),
                    mEntryMinDuration.itemAt(j + 2, Type2Type<MINT64>()),
                    mEntryMinDuration.itemAt(j + 3, Type2Type<MINT64>()),
                    mEntryStallDuration.itemAt(j + 3, Type2Type<MINT64>()));
                break;
  
    mFrameHandler->setOperationMode((uint32_t)requestedConfiguration.v3_4.operationMode);
        std::string const streamName = "Meta:App:Control";
        auto pStreamInfo = createMetaStreamInfo(streamName.c_str(), streamId);
        mFrameHandler->addConfigStream(pStreamInfo);

        rStreams.vMetaStreams.add(streamId, pStreamInfo);
    }
        sp<AppImageStreamInfo> pStreamInfo = mFrameHandler->getConfigImageStream(streamId);
            mFrameHandler->addConfigStream(pStreamInfo.get(), false/*keepBufferCache*/);
     
               //physical settings
                String8 const streamName = String8::format("Meta:App:Physical_%s", ((std::string)srcStream.physicalCameraId).c_str());
                StreamId_T const streamId = eSTREAMID_BEGIN_OF_PHYSIC_ID + (int64_t)pcId;
                auto pMetaStreamInfo = createMetaStreamInfo(streamName.c_str(), streamId, pcId);
                mFrameHandler->addConfigStream(pMetaStreamInfo);
                rStreams.vMetaStreams_physical.add(pcId, pMetaStreamInfo);
            }
        }
}

vendor/mediatek/proprietary/hardware/mtkcam3/main/hal/device/3.x/app/AppStreamMgr.FrameHandler.cpp

这块有一些具体的函数就不继续罗列了

这块是设置上层下发的流的格式。

2.1 config stage log

    2.1.1 PipelineModelSessionFactory log

       log具体含义，看《MTK_camera_pipeline_framework.pdf》

//todo后面还有很多log

3、结语

代码熟练度还不够溜，MTK Code细节不够火候，还需继续深入。我会不定期分享，以便查漏补缺，相互学习。奥里给！！！
