+     *
+     * <p>There are some CaptureRequest keys which can be applied earlier than others
+     * when controls within a CaptureRequest aren't required to take effect at the same time.
+     * One such example is zoom. Zoom can be applied at a later stage of the camera pipeline.
+     * As soon as the camera device receives the CaptureRequest, it can apply the requested
+     * zoom value onto an earlier request that's already in the pipeline, thus improves zoom
+     * latency.</p>
+     * <p>This key's value in the capture result reflects whether the controls for this capture
+     * 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>

+# 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

 For example, suppose you are converting from 44100 Hz to 48000 Hz and using an input buffer with 960 frames. If you calculate the number of output frames you get:
 
-    960 * 48000 * 44100 = 1044.897959...
+    960.0 * 48000 / 44100 = 1044.897959...
 
 You cannot generate a fractional number of frames. So the resampler will sometimes generate 1044 frames and sometimes 1045 frames. On average it will generate 1044.897959 frames. The resampler stores the fraction internally and keeps track of when to consume or generate a frame.

+// 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.
