The better way to record the video from the DVR into the Google Drive is by setting up the events such as motion detection, so the movements in front of the camera can be the trigger the process. Click on the Basic Event button on the left side menu and enable the motion detection for each camera you want to record into the cloud. Find ‘Cameras’ on this list, and click on the arrow next to it to view all individual devices available. Then right-click on the Camera device you use (if there is more than one installed on your system), and select ‘Update driver’ from the context menu if the option is available.

Android's camera hardware abstraction layer (HAL) connects the higher-levelcamera framework APIs inCamera 2 to your underlying camera driver and hardware. The camera subsystemincludes implementations for camera pipeline components while the camera HALprovides interfaces for use in implementing your version of thesecomponents.

Note: If you are implementing the Camera HAL on Android 8.0 and higher, you must use the HIDL interface. For information on the legacy components, see Legacy HAL components.

Architecture

The following figure and list describe the HAL components.

Figure 1. Camera architecture

app framework
At the app framework level is the app's code, which uses the Camera 2 API to interact with the camera hardware. Internally, this code calls corresponding Binder interfaces to access the native code that interacts with the camera.
AIDL
The binder interface associated with CameraService can be found at frameworks/av/camera/aidl/android/hardware. The generated code calls the lower level native code to obtain access to the physical camera and returns data that is used to create the CameraDevice and eventually CameraCaptureSession objects at the framework level.
native framework
This framework residing in frameworks/av/ provides a native equivalent to the CameraDevice and CameraCaptureSession classes. See also NDK camera2 reference.
binder IPC interface
The IPC binder interface facilitates communication over process boundaries. There are several camera binder classes located in the frameworks/av/camera/camera/aidl/android/hardware directory that call into camera service. ICameraService is the interface to the camera service; ICameraDeviceUser is the interface to a specific opened camera device; and ICameraServiceListener and ICameraDeviceCallbacks are the respective CameraService and CameraDevice callbacks to the application framework.
camera service
The camera service, located in frameworks/av/services/camera/libcameraservice/CameraService.cpp, is the actual code that interacts with the HAL.
HAL
The hardware abstraction layer defines the standard interface that the camera service calls into and that you must implement to have your camera hardware function correctly.

Implementing the HAL

The HAL sits between the camera driver and the higher-level Android frameworkand defines an interface that you must implement so apps can correctly operatethe camera hardware. The HIDLinterfaces for the Camera HAL are defined inhardware/interfaces/camera.

A typical binderized HAL must implement the following HIDL interfaces:

  • ICameraProvider: For enumerating individual devices and managing their status.
  • ICameraDevice: The camera device interface.
  • ICameraDeviceSession: The active camera device session interface.

Reference HIDL implementations are available forCameraProvider.cpp,CameraDevice.cpp, andCameraDeviceSession.cpp.The implementation wraps old HALs that still use thelegacy API.Starting with Android 8.0, Camera HAL implementations must use the HIDL API; useof the legacy interface isn't supported.

Update Camera Drivers

This section describes the architecture of the legacy HAL components and how toimplement the HAL. Camera HAL implementations on Android 8.0 and higher must usethe HIDL API instead, described above.

The following figure and list describe the legacy camera HAL components.

app framework
At the app framework level is the app's code, which uses the android.hardware.Camera API to interact with the camera hardware. Internally, this code calls a corresponding JNI glue class to access the native code that interacts with the camera.
JNI
The JNI code associated with android.hardware.Camera is located in frameworks/base/core/jni/android_hardware_Camera.cpp. This code calls the lower-level native code to obtain access to the physical camera and returns data that is used to create the android.hardware.Camera object at the framework level.
native framework
The native framework defined in frameworks/av/camera/Camera.cpp provides a native equivalent to the android.hardware.Camera class. This class calls the IPC binder proxies to obtain access to the camera service.
binder IPC proxies
The IPC binder proxies facilitate communication over process boundaries. There are three camera binder classes that are located in the frameworks/av/camera directory that calls into camera service. ICameraService is the interface to the camera service, ICamera is the interface to a specific opened camera device, and ICameraClient is the device's interface back to the app framework.
camera service
The camera service, located in frameworks/av/services/camera/libcameraservice/CameraService.cpp, is the actual code that interacts with the HAL.
HAL
The hardware abstraction layer defines the standard interface that the camera service calls into and that you must implement to have your camera hardware function correctly.
kernel driver
The camera's driver interacts with the actual camera hardware and your implementation of the HAL. The camera and driver must support YV12 and NV21 image formats to provide support for previewing the camera image on the display and video recording.

Implementing the HAL (legacy)

The HAL sits between the camera driver and the higher-level Android frameworkand defines an interface that you must implement so apps can correctly operatethe camera hardware. The HAL interface is defined in thehardware/libhardware/include/hardware/camera.h andhardware/libhardware/include/hardware/camera_common.h header files.

camera_common.h defines camera_module, a standardstructure to obtain general information about the camera, such as the camera IDand properties common to all cameras (that is, whether it is a front- orback-facing camera).

camera.h contains code that corresponds toandroid.hardware.Camera. This header file declares acamera_device struct that in turn contains acamera_device_ops struct with pointers to functions that implementthe HAL interface. For documentation on the camera parameters developers canset, refer to frameworks/av/include/camera/CameraParameters.h.These parameters are set with the function pointed to by int(*set_parameters)(struct camera_device *, const char *parms) in the HAL.

For an example of a HAL implementation, refer to the implementation for theGalaxy Nexus HAL in hardware/ti/omap4xxx/camera.

Configuring the shared library

Set up the Android build system to correctly package the HAL implementationinto a shared library and copy it to the appropriate location by creating anAndroid.mk file:

Google
  1. Create a device/<company_name>/<device_name>/cameradirectory to contain your library's source files.
  2. Create an Android.mk file to build the shared library. Ensurethat the makefile contains the following lines:

    Your library must be named camera.<device_name>(.so is appended automatically), so Android can correctly load thelibrary. For an example, see the makefile for the Galaxy Nexus camera located inhardware/ti/omap4xxx/Android.mk.

  3. Specify your device has camera features by copying the necessary feature XMLfiles in the frameworks/native/data/etc directory with yourdevice's makefile. For example, to specify your device has a camera flash andcan autofocus, add the following lines in your device's<device>/<company_name>/<device_name>/device.mkmakefile:

    For an example of a device makefile, seedevice/samsung/tuna/device.mk.

  4. Declare your camera’s media codec, format, and resolution capabilities indevice/<company_name>/<device_name>/media_profiles.xmland device/<company_name>/<device_name>/media_codecs.xmlXML files. For details, seeExposing codecs to theframework.
  5. Add the following lines in your device'sdevice/<company_name>/<device_name>/device.mk makefileto copy the media_profiles.xml and media_codecs.xmlfiles to the appropriate location:
  6. To include the Camera app in your device's system image, specify it in thePRODUCT_PACKAGES variable in your device'sdevice/<company>/<device>/device.mkmakefile:
