如何检查安卓设备是否支持用于camera2或cameraX视频稳定的OIS或EIS

Question

我正在使用Java for android，但我找不到任何如何检查android设备是否支持cameraX/Camera2的OIS/EIS视频稳定的示例。

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);

我分别使用了上面两个代码，但我看不出有什么不同。因此，我怀疑我使用的设备不支持EIS和OIS，但我必须进行检查。

您可以从cameraCharacterstics获取可用性信息
