+ *
+ * <p>Pre-allocate all buffers for an output window.</p>
+ *
+ * <p>Normally, the image buffers for a given output window are allocated on-demand,
+ * to minimize startup latency and memory overhead.</p>
+ *
+ * <p>However, in some cases, it may be desirable for the buffers to be allocated before
+ * any requests targeting the window are actually submitted to the device. Large buffers
+ * may take some time to allocate, which can result in delays in submitting requests until
+ * sufficient buffers are allocated to reach steady-state behavior. Such delays can cause
+ * bursts to take longer than desired, or cause skips or stutters in preview output.</p>
+ *
+ * <p>The ACameraCaptureSession_prepare() call can be used to perform this pre-allocation.
+ * It may only be called for a given output window before that window is used as a target for a
+ * request. The number of buffers allocated is the sum of the count needed by the consumer providing
+ * the output window, and the maximum number needed by the camera device to fill its pipeline.
+ * Since this may be a larger number than what is actually required for steady-state operation,
+ * using this call may result in higher memory consumption than the normal on-demand behavior
+ * results in. This method will also delay the time to first output to a given Surface, in exchange
+ * for smoother frame rate once the allocation is complete.</p>
+ *
+ * <p>For example, an application that creates an
+ * {@link AImageReader} with a maxImages argument of 10,
+ * but only uses 3 simultaneous {@link AImage}s at once, would normally only cause those 3 images
+ * to be allocated (plus what is needed by the camera device for smooth operation).  But using
+ * ACameraCaptureSession_prepare() on the {@link AImageReader}'s window will result in all 10
+ * {@link AImage}s being allocated. So applications using this method should take care to request
+ * only the number of buffers actually necessary for their application.</p>
+ *
+ * <p>If the same output window is used in consecutive sessions (without closing the first
+ * session explicitly), then its already-allocated buffers are carried over, and if it was
+ * used as a target of a capture request in the first session, prepare cannot be called on it
+ * in the second session. If it is, {@link ACAMERA_ERROR_INVALID_PARAMETER} will
+ * be returned by the method</p>
+ *
+ * <p>Once allocation is complete, {@link ACameraCaptureSession_prepareCallback#onWindowPrepared}
+ * will be invoked with the output provided to this method. Between the prepare call and the
+ * {@link ACameraCaptureSession_prepareCallback#onWindowPrepared} call,
+ * the output provided to prepare must not be used as a target of a capture request submitted
+ * to this session.</p>
+ *
+ * <p>{@link android.hardware.camera2.CameraCharacteristics#INFO_SUPPORTED_HARDWARE_LEVEL_LEGACY LEGACY}
+ * devices cannot pre-allocate output buffers; for those devices,
+ * {@link ACameraCaptureSession_prepareCallback#onWindowPrepared} will be immediately called,
+ * and no pre-allocation is done.</p>
+ *
+ * @param session the {@link ACameraCaptureSession} that needs to prepare output buffers.

+     * </ul></p>
+     *
+     * <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

+## AIDL error handling
+
+Starting in **Android U (14)**, `libmediadrm` (app-side) understands extra error
+details from **AIDL** DRM HALs passed through the binder exception message
+as a json string. The supported fields are:
+* `cdmError` (*int*)
+* `oemError` (*int*)
+* `context` (*int*)
+* `errorMessage` (*str*)
+
+The errors details will be reported to apps through the java interface
+`android.media.MediaDrmThrowable`. Please see the javadoc of `MediaDrmThrowable`
+for detailed definitions of each field above.

-# Fuzzer for android.hardware.drm@1.4-service.clearkey
-
-## Plugin Design Considerations
-The fuzzer plugin for android.hardware.drm@1.4-service.clearkey is designed based on the understanding of the
-source code and tries 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 fuzzer.
-
-android.hardware.drm@1.4-service.clearkey supports the following parameters:
-1. Security Level (parameter name: `securityLevel`)
-2. Mime Type (parameter name: `mimeType`)
-3. Key Type (parameter name: `keyType`)
-4. Crypto Mode (parameter name: `cryptoMode`)
-
-| Parameter| Valid Values| Configured Value|

-This also ensures that the plugin is always deterministic for any given input.
-
-##### Maximize utilization of input data
-The plugin feeds the entire input data to the module.
-This ensures that the plugin tolerates any kind of input (empty, huge,
-malformed, etc) and doesnt `exit()` on any input and thereby increasing the
-chance of identifying vulnerabilities.

 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.

+ *
+ * The roll, pitch, and yaw angles are calculated separately from the device frame
+ * rotation from the world frame.  This is not to be confused with the
+ * intrinsic Euler xyz roll, pitch, yaw 'nautical' angles.
+ *
+ * The input quarternion is the active rotation that transforms the
+ * World/Stage frame to the Head/Screen frame.
+ *
+ * The input quaternion may come from two principal sensors: DEVICE and HEADSET
+ * and are interpreted as below.
+ *
+ * DEVICE SENSOR
+ *
+ * Android sensor stack assumes device coordinates along the x/y axis.
+ *
+ * https://developer.android.com/reference/android/hardware/SensorEvent#sensor.type_rotation_vector:
+ *
+ * Looking down from the clouds. Android Device coordinate system (not used)
+ *        DEVICE --> X (Y goes through top speaker towards the observer)
+ *           | Z
+ *           V
+ *         USER
+ *
+ * Internally within this library, we transform the device sensor coordinate
+ * system by rotating the coordinate system around the X axis by -M_PI/2.
+ * This aligns the device coordinate system to match that of the
+ * Head Tracking sensor (see below), should the user be facing the device in
+ * natural (phone == portrait, tablet == ?) orientation.
+ *
+ * Looking down from the clouds. Spatializer device frame.
+ *           Y
+ *           ^
+ *           |
+ *        DEVICE --> X (Z goes through top of the DEVICE towards the observer)
+ *
+ *         USER
+ *
+ * The reference world frame is the device in vertical
+ * natural (phone == portrait) orientation with the top pointing straight
+ * up from the ground and the front-to-back direction facing north.
+ * The world frame is presumed locally fixed by magnetic and gravitational reference.
+ *
+ * HEADSET SENSOR
+ * https://developer.android.com/reference/android/hardware/SensorEvent#sensor.type_head_tracker:
+ *
+ * Looking down from the clouds. Headset frame.
+ *           Y
+ *           ^
+ *           |
+ *         USER ---> X
+ *         (Z goes through the top of the USER head towards the observer)
+ *
+ * The Z axis goes from the neck to the top of the head, the X axis goes
+ * from the left ear to the right ear, the Y axis goes from the back of the
+ * head through the nose.
+ *
+ * Typically for a headset sensor, the X and Y axes have some arbitrary fixed
+ * reference.
+ *
+ * ROLL
+ * Roll is the counter-clockwise L/R motion around the Y axis (hence ZX plane).
+ * The right hand convention means the plane is ZX not XZ.
+ * This can be considered the azimuth angle in spherical coordinates
+ * with Pitch being the elevation angle.
+ *
+ * Roll has a range of -M_PI to M_PI radians.
+ *
+ * Rolling a device changes between portrait and landscape
+ * modes, and for L/R speakers will limit the amount of crosstalk cancellation.
+ * Roll increases as the device (if vertical like a coin) rolls from left to right.
+ *
+ * By this definition, Roll is less accurate when the device is flat
+ * on a table rather than standing on edge.
+ * When perfectly flat on the table, roll may report as 0, M_PI, or -M_PI
+ * due ambiguity / degeneracy of atan(0, 0) in this case (the device Y axis aligns with
+ * the world Z axis), but exactly flat rarely occurs.
+ *
+ * Roll for a headset is the angle the head is inclined to the right side
+ * (like sleeping).
+ *
+ * PITCH
+ * Pitch is the Surface normal Y deviation (along the Z axis away from the earth).
+ * This can be considered the elevation angle in spherical coordinates using
+ * Roll as the azimuth angle.
+ *
+ * Pitch for a device determines whether the device is "upright" or lying
+ * flat on the table (i.e. surface normal).  Pitch is 0 when upright, decreases
+ * as the device top moves away from the user to -M_PI/2 when lying down face up.
+ * Pitch increases from 0 to M_PI/2 when the device tilts towards the user, and is
+ * M_PI/2 degrees when face down.
+ *
+ * Pitch for a headset is the user tilting the head/chin up or down,
+ * like nodding.
+ *
+ * Pitch has a range of -M_PI/2, M_PI/2 radians.
+ *
+ * YAW
+ * Yaw is the rotational component along the earth's XY tangential plane,
+ * where the Z axis points radially away from the earth.
+ *
+ * Yaw has a range of -M_PI to M_PI radians.  If used for azimuth angle in
+ * spherical coordinates, the elevation angle may be derived from the Z axis.
+ *
+ * A positive increase means the phone is rotating from right to left
+ * when considered flat on the table.
+ * (headset: the user is rotating their head to look left).
+ * If left speaker or right earbud is pointing straight up or down,
+ * this value is imprecise and Pitch or Roll is a more useful measure.
+ *
+ * Yaw for a device is like spinning a vertical device along the axis of
+ * gravity, like spinning a coin.  Yaw increases as the coin / device
+ * spins from right to left, rotating around the Z axis.
+ *
+ * Yaw for a headset is the user turning the head to look left or right
+ * like shaking the head for no. Yaw is the primary angle for a binaural
+ * head tracking device.

+//   * The desired timestamp passed in by the app, indicating at what point in time in the future
+//     the app would like the frame to be rendered.
+//   * The actual timestamp passed in by the display subsystem, indicating the point in time at
+//     which the frame was actually rendered.
+//
+// Core to the algorithms are deriving frame durations based on these timestamps and determining
+// the result of each video frame in the content stream:
+//   * skipped: the app didn't want to render the frame
+//   * dropped: the display subsystem could not render the frame in time

+ * FixedString is a stack allocatable string buffer that supports
+ * simple appending of other strings and string_views.
+ *
+ * It is designed for no-malloc operation when std::string
+ * small buffer optimization is insufficient.
+ *
+ * To keep code small, use asStringView() for operations on this.
+ *
+ * Notes:
+ * 1) Appending beyond the internal buffer size results in truncation.
+ *
+ * Alternatives:
+ * 1) If you want a sharable copy-on-write string implementation,
+ *    consider using the legacy android::String8().
+ * 2) Using std::string with a fixed stack allocator may suit your needs,
+ *    but exception avoidance is tricky.
+ * 3) Using C++20 ranges https://en.cppreference.com/w/cpp/ranges if you don't
+ *    need backing store.  Be careful about allocation with ranges.
+ *
+ * Good small sizes are multiples of 16 minus 2, e.g. 14, 30, 46, 62.
+ *
+ * Implementation Notes:
+ * 1) No iterators or [] for FixedString - please convert to std::string_view.
+ * 2) For small N (e.g. less than 62), consider a change to always zero fill and
+ *    potentially prevent always zero terminating (if one only does append).
+ *
+ * Possible arguments to create/append:
+ * 1) A FixedString.
+ * 2) A single char.
+ * 3) A char * pointer.
+ * 4) A std::string.
+ * 5) A std::string_view (or something convertible to it).
+ *
+ * Example:
+ *
+ * FixedString s1(std::string("a"));    // ctor
+ * s1 << "bc" << 'd' << '\n';           // streaming append
+ * s1 += "hello";                       // += append

+// 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
