Untuk perangkat yang menjalankan Android 13 atau yang lebih baru, framework
kamera memberikan dukungan untuk stabilisasi video pada streaming pratinjau
dan streaming non-RAW lainnya dalam sesi pengambilan kamera. Fitur ini memungkinkan
aplikasi pihak ketiga memberikan pengalaman apa yang Anda lihat itu yang Anda dapatkan (WYSIWYG)
saat membandingkan antara pratinjau kamera dan rekaman.
Implementasi
Untuk menyediakan fitur ini kepada aplikasi pihak ketiga, produsen
perangkat harus mengiklankan dukungan untuk kunci berikut dan menerapkan
algoritma stabilisasi pratinjau di HAL kamera:
Untuk mengubah setelan default fitur ini, tetapkan nilai default di
template permintaan pengambilan saat membuat permintaan pengambilan menggunakan
createCaptureRequest.
Untuk implementasi referensi fitur ini, lihat kode untuk
EmulatedCamera di Cuttlefish di
hardware/google/camera/devices/EmulatedCamera/hwl/EmulatedSensor.cpp.
Untuk mengetahui detail selengkapnya tentang mode stabilisasi video, lihat
CONTROL_VIDEO_STABILIZATION_MODE.
Validasi
Untuk menguji implementasi fitur ini, gunakan pengujian CTS dan ITS
berikut:
CTS:
ITS (menguji bidang pandang dan kualitas stabilisasi):

This feature lets\nthird-party apps provide a *what you see is what you get* (WYSIWYG) experience\nwhen comparing between the camera preview and the recording.\n\nImplementation\n--------------\n\nTo provide third-party apps with this feature, device\nmanufacturers must advertise support for the following keys and implement\npreview stabilization algorithms in the camera HAL:\n\n- [`CONTROL_AVAILABLE_VIDEO_STABILIZATION_MODES`](https://developer.android.com/reference/android/hardware/camera2/CameraCharacteristics#CONTROL_AVAILABLE_VIDEO_STABILIZATION_MODES)\n- [`CONTROL_VIDEO_STABILIZATION_MODE_PREVIEW_STABILIZATION`](https://developer.android.com/reference/android/hardware/camera2/CameraMetadata#CONTROL_VIDEO_STABILIZATION_MODE_PREVIEW_STABILIZATION)\n\nTo modify the default settings for this feature, assign a default value in the\ncapture request template when creating a capture request using\n[`createCaptureRequest`](https://developer.android.com/reference/android/hardware/camera2/CameraDevice#createCaptureRequest(int,%20java.util.Set%3Cjava.lang.String%3E)).\n\nFor a reference implementation of this feature, see the code for\n`EmulatedCamera` in [Cuttlefish](/docs/devices/cuttlefish) at\n[`hardware/google/camera/devices/EmulatedCamera/hwl/EmulatedSensor.cpp`](https://cs.android.com/android/platform/superproject/+/android-latest-release:hardware/google/camera/devices/EmulatedCamera/hwl/EmulatedSensor.cpp#823).\n\nFor more details on video stabilization modes, see\n[`CONTROL_VIDEO_STABILIZATION_MODE`](https://developer.android.com/reference/android/hardware/camera2/CaptureRequest#CONTROL_VIDEO_STABILIZATION_MODE).\n\nValidation\n----------\n\nTo test your implementation of this feature, use the following CTS and ITS\ntests:\n\nCTS:\n\n- [`RobustnessTest.java#testMandatoryPreviewStabilizationOutputCombinations`](https://cs.android.com/android/platform/superproject/+/android-latest-release:cts/tests/camera/src/android/hardware/camera2/cts/RobustnessTest.java)\n\nITS (tests field of view and stabilization quality):\n\n- [`scene4/test_preview_Stabilization_fov.py`](/docs/compatibility/cts/camera-its-tests#test_preview_stabilization_fov)\n- [`sensor_fusion/test_preview_stabilization.py`](/docs/compatibility/cts/camera-its-tests#test_preview_stabilization)"]]
