+     * unavoidable, such as foldables or other devices with variable display geometry or more
+     * free-form window placement (such as laptops, which often place portrait-orientation apps
+     * in landscape with pillarboxing).</p>
+     * <p>If supported, the default value is <code>ROTATE_AND_CROP_AUTO</code>, which allows the camera API
+     * to enable backwards-compatibility support for applications that do not support resizing
+     * / multi-window modes, when the device is in fact in a multi-window mode (such as inset
+     * portrait on laptops, or on a foldable device in some fold states).  In addition,
+     * <code>ROTATE_AND_CROP_NONE</code> and <code>ROTATE_AND_CROP_90</code> will always be available if this control
+     * is supported by the device.  If not supported, devices API level 30 or higher will always
+     * list only <code>ROTATE_AND_CROP_NONE</code>.</p>
+     * <p>When <code>CROP_AUTO</code> is in use, and the camera API activates backward-compatibility mode,
+     * several metadata fields will also be parsed differently to ensure that coordinates are
+     * correctly handled for features like drawing face detection boxes or passing in
+     * tap-to-focus coordinates.  The camera API will convert positions in the active array
+     * coordinate system to/from the cropped-and-rotated coordinate system to make the
+     * operation transparent for applications.  The following controls are affected:</p>
+     * <ul>
+     * <li>ACAMERA_CONTROL_AE_REGIONS</li>
+     * <li>ACAMERA_CONTROL_AF_REGIONS</li>
+     * <li>ACAMERA_CONTROL_AWB_REGIONS</li>
+     * <li>android.statistics.faces</li>
+     * </ul>
+     * <p>Capture results will contain the actual value selected by the API;
+     * <code>ROTATE_AND_CROP_AUTO</code> will never be seen in a capture result.</p>
+     * <p>Applications can also select their preferred cropping mode, either to opt out of the
+     * backwards-compatibility treatment, or to use the cropping feature themselves as needed.
+     * In this case, no coordinate translation will be done automatically, and all controls
+     * will continue to use the normal active array coordinates.</p>
+     * <p>Cropping and rotating is done after the application of digital zoom (via either
+     * ACAMERA_SCALER_CROP_REGION or ACAMERA_CONTROL_ZOOM_RATIO), but before each individual
+     * output is further cropped and scaled. It only affects processed outputs such as
+     * YUV, PRIVATE, and JPEG.  It has no effect on RAW outputs.</p>
+     * <p>When <code>CROP_90</code> or <code>CROP_270</code> are selected, there is a significant loss to the field of
+     * view. For example, with a 4:3 aspect ratio output of 1600x1200, <code>CROP_90</code> will still
+     * produce 1600x1200 output, but these buffers are cropped from a vertical 3:4 slice at the
+     * center of the 4:3 area, then rotated to be 4:3, and then upscaled to 1600x1200.  Only
+     * 56.25% of the original FOV is still visible.  In general, for an aspect ratio of <code>w:h</code>,
+     * the crop and rotate operation leaves <code>(h/w)^2</code> of the field of view visible. For 16:9,
+     * this is ~31.6%.</p>
+     * <p>As a visual example, the figure below shows the effect of <code>ROTATE_AND_CROP_90</code> on the
+     * outputs for the following parameters:</p>
+     * <ul>
+     * <li>Sensor active array: <code>2000x1500</code></li>
+     * <li>Crop region: top-left: <code>(500, 375)</code>, size: <code>(1000, 750)</code> (4:3 aspect ratio)</li>
+     * <li>Output streams: YUV <code>640x480</code> and YUV <code>1280x720</code></li>
+     * <li><code>ROTATE_AND_CROP_90</code></li>
+     * </ul>
+     * <p><img alt="Effect of ROTATE_AND_CROP_90" src="../images/camera2/metadata/android.scaler.rotateAndCrop/crop-region-rotate-90-43-ratio.png" /></p>
+     * <p>With these settings, the regions of the active array covered by the output streams are:</p>
+     * <ul>
+     * <li>640x480 stream crop: top-left: <code>(219, 375)</code>, size: <code>(562, 750)</code></li>

+     * </ul>
+     * <p>Since the buffers are rotated, the buffers as seen by the application are:</p>
+     * <ul>
+     * <li>640x480 stream: top-left: <code>(781, 375)</code> on active array, size: <code>(640, 480)</code>, downscaled 1.17x from sensor pixels</li>

+# <a name="midiExtractorFuzzer"></a> Fuzzer for libmidiextractor
+
+## Plugin Design Considerations
+The fuzzer plugin for MIDI extractor uses the `ExtractorFuzzerBase` class and
+implements only the `createExtractor` to create the MIDI extractor class.
+
+##### Maximize code coverage
+Dict file (dictionary file) is created for MIDI to ensure that the required MIDI
+headers are present in every input file that goes to the fuzzer.
+This ensures that larger code gets covered as a range of MIDI headers will be
+present in the input data.
+
+
+## Build
+
+This describes steps to build midi_extractor_fuzzer binary.
+
+### Android
+
+#### Steps to build
+Build the fuzzer
+```
+  $ mm -j$(nproc) midi_extractor_fuzzer
+```
+
+#### Steps to run
+Create a directory CORPUS_DIR and copy some MIDI files to that folder
+Push this directory to device.
+
+To run on device
+```
+  $ adb sync data
+  $ adb shell /data/fuzz/arm64/midi_extractor_fuzzer/midi_extractor_fuzzer CORPUS_DIR
+```

+# libshmem
+
+This library provides facilities for sharing memory across processes over (stable) AIDL. The main
+feature is the definition of the `android.media.SharedMemory` AIDL type, which represents a block of
+memory that can be shared between processes. In addition, a few utilities are provided to facilitate
+the use of shared memory and to integrate with legacy code that uses older facilities.

-/**
- * CameraHardwareInterface.h defines the interface to the
- * camera hardware abstraction layer, used for setting and getting
- * parameters, live previewing, and taking pictures. It is used for
- * HAL devices with version CAMERA_DEVICE_API_VERSION_1_0 only.
- *
- * It is a referenced counted interface with RefBase as its base class.
- * CameraService calls openCameraHardware() to retrieve a strong pointer to the
- * instance of this interface and may be called multiple times. The
- * following steps describe a typical sequence:
- *
- *   -# After CameraService calls openCameraHardware(), getParameters() and
- *      setParameters() are used to initialize the camera instance.
- *   -# startPreview() is called.
- *
- * Prior to taking a picture, CameraService often calls autofocus(). When auto
- * focusing has completed, the camera instance sends a CAMERA_MSG_FOCUS notification,
- * which informs the application whether focusing was successful. The camera instance
- * only sends this message once and it is up  to the application to call autoFocus()
- * again if refocusing is desired.
- *
- * CameraService calls takePicture() to request the camera instance take a
- * picture. At this point, if a shutter, postview, raw, and/or compressed
- * callback is desired, the corresponding message must be enabled. Any memory
- * provided in a data callback must be copied if it's needed after returning.
