如何檢查android設備是否支持用於camera2或cameraX視頻穩定的OIS或EIS

Question

我正在為 android 使用 Java，但找不到任何關於如何檢查 android 設備是否支持 cameraX/Camera2 的 OIS/EIS 視頻穩定的示例。

Camera2CameraControl camera2CameraControl =
            Camera2CameraControl.from(camera.getCameraControl());
    CaptureRequestOptions captureRequestOptions =
            new CaptureRequestOptions.Builder()
                    .setCaptureRequestOption(CaptureRequest.CONTROL_VIDEO_STABILIZATION_MODE, CameraMetadata.CONTROL_VIDEO_STABILIZATION_MODE_ON)
                    .build();
    camera2CameraControl.setCaptureRequestOptions(captureRequestOptions);


Camera2CameraControl camera2CameraControl =
            Camera2CameraControl.from(camera.getCameraControl());
    CaptureRequestOptions captureRequestOptions =
            new CaptureRequestOptions.Builder()
                    .setCaptureRequestOption(CaptureRequest.LENS_OPTICAL_STABILIZATION_MODE, CameraMetadata.LENS_OPTICAL_STABILIZATION_MODE_ON)
                    .build();
    camera2CameraControl.setCaptureRequestOptions(captureRequestOptions);

我分別使用了上面的兩個代碼，但我沒有看到任何區別。 所以我懷疑我使用的設備不支持 EIS 和 OIS，但我必須檢查。
