+     * are overridden "by" a newer request. This means that if a capture request turns on
+     * settings override, the capture result of an earlier request will contain the key value
+     * of ZOOM. On the other hand, if a capture request has settings override turned on,
+     * but all newer requests have it turned off, the key's value in the capture result will
+     * be OFF because this capture isn't overridden by a newer capture. In the two examples
+     * below, the capture results columns illustrate the settingsOverride values in different
+     * scenarios.</p>
+     * <p>Assuming the zoom settings override can speed up by 1 frame, below example illustrates
+     * the speed-up at the start of capture session:</p>
+     * <pre><code>Camera session created
+     * Request 1 (zoom=1.0x, override=ZOOM) -&gt;
+     * Request 2 (zoom=1.2x, override=ZOOM) -&gt;
+     * Request 3 (zoom=1.4x, override=ZOOM) -&gt;  Result 1 (zoom=1.2x, override=ZOOM)
+     * Request 4 (zoom=1.6x, override=ZOOM) -&gt;  Result 2 (zoom=1.4x, override=ZOOM)
+     * Request 5 (zoom=1.8x, override=ZOOM) -&gt;  Result 3 (zoom=1.6x, override=ZOOM)
+     *                                      -&gt;  Result 4 (zoom=1.8x, override=ZOOM)
+     *                                      -&gt;  Result 5 (zoom=1.8x, override=OFF)
+     * </code></pre>
+     * <p>The application can turn on settings override and use zoom as normal. The example
+     * shows that the later zoom values (1.2x, 1.4x, 1.6x, and 1.8x) overwrite the zoom
+     * values (1.0x, 1.2x, 1.4x, and 1.8x) of earlier requests (#1, #2, #3, and #4).</p>
+     * <p>The application must make sure the settings override doesn't interfere with user
+     * journeys requiring simultaneous application of all controls in CaptureRequest on the
+     * requested output targets. For example, if the application takes a still capture using
+     * CameraCaptureSession#capture, and the repeating request immediately sets a different
+     * zoom value using override, the inflight still capture could have its zoom value
+     * overwritten unexpectedly.</p>
+     * <p>So the application is strongly recommended to turn off settingsOverride when taking
+     * still/burst captures, and turn it back on when there is only repeating viewfinder
+     * request and no inflight still/burst captures.</p>
+     * <p>Below is the example demonstrating the transitions in and out of the
+     * settings override:</p>
+     * <pre><code>Request 1 (zoom=1.0x, override=OFF)
+     * Request 2 (zoom=1.2x, override=OFF)
+     * Request 3 (zoom=1.4x, override=ZOOM)  -&gt; Result 1 (zoom=1.0x, override=OFF)
+     * Request 4 (zoom=1.6x, override=ZOOM)  -&gt; Result 2 (zoom=1.4x, override=ZOOM)
+     * Request 5 (zoom=1.8x, override=OFF)   -&gt; Result 3 (zoom=1.6x, override=ZOOM)
+     *                                       -&gt; Result 4 (zoom=1.6x, override=OFF)
+     *                                       -&gt; Result 5 (zoom=1.8x, override=OFF)
+     * </code></pre>
+     * <p>This example shows that:</p>
+     * <ul>
+     * <li>The application "ramps in" settings override by setting the control to ZOOM.
+     * In the example, request #3 enables zoom settings override. Because the camera device
+     * can speed up applying zoom by 1 frame, the outputs of request #2 has 1.4x zoom, the
+     * value specified in request #3.</li>
+     * <li>The application "ramps out" of settings override by setting the control to OFF. In
+     * the example, request #5 changes the override to OFF. Because request #4's zoom
+     * takes effect in result #3, result #4's zoom remains the same until new value takes
+     * effect in result #5.</li>
+     * </ul>

+# Fuzzers for libcamera_client
+
+## Plugin Design Considerations
+The fuzzer plugins for libcamera_client are designed based on the understanding of the
+source code and try to achieve the following:
+
+##### Maximize code coverage
+The configuration parameters are not hardcoded, but instead selected based on
+incoming data. This ensures more code paths are reached by the fuzzers.
+
+libcamera_client supports the following parameters:
+1. Command (parameter name: `cmd`)
+2. Video Buffer Mode (parameter name: `videoBufferMode`)
+3. Preview Callback Flag (parameter name: `previewCallbackFlag`)
+4. Facing (parameter name: `facing`)
+5. Orientation (parameter name: `orientation`)
+6. Format (parameter name: `format`)
+
+| Parameter| Valid Values| Configured Value|
+|------------- |-------------| ----- |
+| `cmd` | 0.`CAMERA_CMD_START_SMOOTH_ZOOM` 1.`CAMERA_CMD_STOP_SMOOTH_ZOOM` 3.`CAMERA_CMD_SET_DISPLAY_ORIENTATION` 4.`CAMERA_CMD_ENABLE_SHUTTER_SOUND` 5.`CAMERA_CMD_PLAY_RECORDING_SOUND` 6.`CAMERA_CMD_START_FACE_DETECTION` 7.`CAMERA_CMD_STOP_FACE_DETECTION` 8.`CAMERA_CMD_ENABLE_FOCUS_MOVE_MSG` 9.`CAMERA_CMD_PING` 10.`CAMERA_CMD_SET_VIDEO_BUFFER_COUNT` 11.`CAMERA_CMD_SET_VIDEO_FORMAT`| Value obtained from FuzzedDataProvider|
+| `videoBufferMode` |0. `ICamera::VIDEO_BUFFER_MODE_DATA_CALLBACK_YUV` 1.`ICamera::VIDEO_BUFFER_MODE_DATA_CALLBACK_METADATA` 2.`ICamera::VIDEO_BUFFER_MODE_BUFFER_QUEUE`| Value obtained from FuzzedDataProvider|
+| `previewCallbackFlag` | 0. `CAMERA_FRAME_CALLBACK_FLAG_ENABLE_MASK` 1.`CAMERA_FRAME_CALLBACK_FLAG_ONE_SHOT_MASK` 2.`CAMERA_FRAME_CALLBACK_FLAG_COPY_OUT_MASK` 3.`CAMERA_FRAME_CALLBACK_FLAG_NOOP` 4.`CAMERA_FRAME_CALLBACK_FLAG_CAMCORDER` 5.`CAMERA_FRAME_CALLBACK_FLAG_CAMERA` 6.`CAMERA_FRAME_CALLBACK_FLAG_BARCODE_SCANNER`| Value obtained from FuzzedDataProvider|
+| `facing` | 0.`android::hardware::CAMERA_FACING_BACK` 1.`android::hardware::CAMERA_FACING_FRONT`| Value obtained from FuzzedDataProvider|
+| `orientation` | 0.`0` 1.`90` 2.`180`3.`270`| Value obtained from FuzzedDataProvider|
+| `format` | 0.`CameraParameters::PIXEL_FORMAT_YUV422SP` 1.`CameraParameters::PIXEL_FORMAT_YUV420SP` 2.`CameraParameters::PIXEL_FORMAT_YUV422I` 3.`CameraParameters::PIXEL_FORMAT_YUV420P` 4.`CameraParameters::PIXEL_FORMAT_RGB565` 5.`CameraParameters::PIXEL_FORMAT_RGBA8888` 6.`CameraParameters::PIXEL_FORMAT_JPEG` 7.`CameraParameters::PIXEL_FORMAT_BAYER_RGGB` 8.`CameraParameters::PIXEL_FORMAT_ANDROID_OPAQUE`| Value obtained from FuzzedDataProvider|
+
+This also ensures that the plugins are always deterministic for any given input.
+
+##### Maximize utilization of input data
+The plugins feed the entire input data to the module.
+This ensures that the plugins tolerate any kind of input (empty, huge,
+malformed, etc) and dont `exit()` on any input and thereby increasing the
+chance of identifying vulnerabilities.
+
+## Build
+
+This describes steps to build camera_fuzzer, camera2CaptureRequest_fuzzer, camera2ConcurrentCamera_fuzzer, camera2SubmitInfo_fuzzer, camera2SessionConfiguration_fuzzer, camera2OutputConfiguration_fuzzer, vendorTagDescriptor_fuzzer, cameraParameters_fuzzer, cameraSessionStats_fuzzer and captureResult_fuzzer binaries

+// This class is an *almost* drop-in replacement for std::function which is guaranteed to never
+// allocate, and always holds the type erased functional object in an in-line small buffer of
+// templated size. If the object is too large to hold, the type will fail to instantiate.
+//
+// Some notable differences are:
+// - operator() is not const (unlike std::function where the call operator is
+// const even if the erased type is not const callable). This retains const
+// correctness by default. A workaround is keeping InPlaceFunction mutable.
+// - Moving from an InPlaceFunction leaves the object in a valid state (operator
+// bool remains true), similar to std::optional/std::variant.
+// Calls to the object are still defined (and are equivalent
+// to calling the underlying type after it has been moved from). To opt-out
+// (and/or ensure safety), clearing the object is recommended:
+//      func1 = std::move(func2); // func2 still valid (and moved-from) after this line
+//      func2 = nullptr; // calling func2 will now abort
+// - Unsafe implicit conversions of the return value to a reference type are
+// prohibited due to the risk of dangling references (some of this safety was
+// added to std::function in c++23). Only converting a reference to a reference to base class is
+// permitted:
+//      std::function<Base&()> = []() -> Derived& {...}
+// - Some (current libc++ implementation) implementations of std::function
+// incorrectly fail to handle returning non-moveable types which is valid given
+// mandatory copy elision.
+//
+// Additionally, the stored functional will use the typical rules of overload
+// resolution to disambiguate the correct call, except, the target class will
+// always be implicitly a non-const lvalue when called. If a different overload
+// is preferred, wrapping the target class in a lambda with explicit casts is
+// recommended (or using inheritance, mixins or CRTP). This avoids the
+// complexity of utilizing abonimable function types as template params.
