+ * must not call ICameraProvider::setTorchMode() for the disconnected camera
+ * device until it is connected again. The camera provider HAL does not
+ * need to invoke ICameraProviderCallback::TorchModeStatusChange()
+ * separately to inform that the flash unit has become NOT_AVAILABLE.
+ *
+ * 3. openCameraDevice() or openCameraDeviceVersion() is called to open a
+ * camera device. The camera provider HAL must invoke
+ * ICameraProviderCallback::TorchModeStatusChange() for all flash units
+ * that have entered NOT_AVAILABLE state and can not be turned on by
+ * calling ICameraProvider::setTorchMode() due to this open() call.
+ * openCameraDevice() must not trigger AVAILABLE_OFF before NOT_AVAILABLE
+ * for all flash units that have become unavailable.
+ *
+ * 4. ICameraDevice.close() is called to close a camera device. The camera
+ * provider HAL must call ICameraProviderCallback::torchModeStatusChange()
+ * for all flash units that have now entered the AVAILABLE_OFF state and
+ * can be turned on by calling ICameraProvider::setTorchMode() again because
+ * of sufficient new camera resources being freed up by this close() call.
+ *
+ * Note that the camera service calling ICameraProvider::setTorchMode()

+ * This may be a very rough estimate, and is used as a hint to the camera
+ * service to determine when to disallow multiple applications from
+ * simultaneously opening different cameras advertised by the camera
+ * service.
+ *
+ * The camera service must be able to simultaneously open and use any
+ * combination of camera devices exposed by the HAL where the sum of
+ * the resource costs of these cameras is <= 100. For determining cost,
+ * each camera device must be assumed to be configured and operating at
+ * the maximally resource-consuming framerate and stream size settings
+ * available in the configuration settings exposed for that device through
+ * the camera metadata.
+ *
+ * The camera service may still attempt to simultaneously open combinations
+ * of camera devices with a total resource cost > 100. This may succeed or
+ * fail. If this succeeds, combinations of configurations that are not
+ * supported due to resource constraints from having multiple open devices
+ * must fail during the configure calls. If the total resource cost is <=
+ * 100, open and configure must never fail for any stream configuration
+ * settings or other device capabilities that would normally succeed for a
+ * device when it is the only open camera device.
+ *
+ * This field may be used to determine whether background applications are
+ * allowed to use this camera device while other applications are using
+ * other camera devices. Note: multiple applications must never be allowed
+ * by the camera service to simultaneously open the same camera device.
+ *
+ * Example use cases:
+ *
+ * Ex. 1: Camera Device 0 = Back Camera
+ * Camera Device 1 = Front Camera
+ * - Using both camera devices causes a large framerate slowdown due to
+ * limited ISP bandwidth.
+ *
+ * Configuration:
+ *
+ * Camera Device 0 - resourceCost = 51
+ * conflicting_devices = empty
+ * Camera Device 1 - resourceCost = 51
+ * conflicting_devices = empty
+ *
+ * Result:
+ *
+ * Since the sum of the resource costs is > 100, if a higher-priority
+ * application has either device open, no lower-priority applications must
+ * be allowed by the camera service to open either device. If a
+ * lower-priority application is using a device that a higher-priority
+ * subsequently attempts to open, the lower-priority application must be
+ * forced to disconnect the the device.
+ *
+ * If the highest-priority application chooses, it may still attempt to
+ * open both devices (since these devices are not listed as conflicting in
+ * the conflicting_devices fields), but usage of these devices may fail in
+ * the open or configure calls.
+ *
+ * Ex. 2: Camera Device 0 = Left Back Camera
+ * Camera Device 1 = Right Back Camera
+ * Camera Device 2 = Combined stereo camera using both right and left
+ * back camera sensors used by devices 0, and 1
+ * Camera Device 3 = Front Camera
+ * - Due to do hardware constraints, up to two cameras may be open at
+ * once. The combined stereo camera may never be used at the same time
+ * as either of the two back camera devices (device 0, 1), and typically
+ * requires too much bandwidth to use at the same time as the front
+ * camera (device 3).
+ *
+ * Configuration:
+ *
+ * Camera Device 0 - resourceCost = 50
+ * conflicting_devices = { 2 }
+ * Camera Device 1 - resourceCost = 50
+ * conflicting_devices = { 2 }
+ * Camera Device 2 - resourceCost = 100

+ * Camera Device 3 - resourceCost = 50

+ * Camera Device 1 = Front Camera
+ * Camera Device 2 = Low-power Front Camera that uses the same sensor

+
+## Overview: ##
+
+The camera.common namesapce is used by the Android camera HALs for common
+enumeration and structure definitions.
+
+This includes standard status codes returned by most camera HAL methods.
+
+More complete information about the Android camera HAL and subsystem can be found at
+[source.android.com](http://source.android.com/devices/camera/index.html).
+
+## Version history: ##
+
+## types.hal: ##
+
+### @1.0:
+
+Common enum and struct definitions for all camera HAL interfaces. Does not
+define any interfaces of its own.

+ * metadata and low-resolution buffers to be returned in one call, and
+ * post-processed JPEG buffers in a later call, once it is available. Each
+ * call must include the frame number of the request it is returning
+ * metadata or buffers for. Only one call to processCaptureResult
+ * may be made at a time by the HAL although the calls may come from
+ * different threads in the HAL.
+ *
+ * A component (buffer or metadata) of the complete result may only be
+ * included in one process_capture_result call. A buffer for each stream,
+ * and the result metadata, must be returned by the HAL for each request in
+ * one of the processCaptureResult calls, even in case of errors producing
+ * some of the output. A call to processCaptureResult() with neither
+ * output buffers or result metadata is not allowed.
+ *
+ * The order of returning metadata and buffers for a single result does not
+ * matter, but buffers for a given stream must be returned in FIFO order. So
+ * the buffer for request 5 for stream A must always be returned before the
+ * buffer for request 6 for stream A. This also applies to the result
+ * metadata; the metadata for request 5 must be returned before the metadata
+ * for request 6.
+ *
+ * However, different streams are independent of each other, so it is
+ * acceptable and expected that the buffer for request 5 for stream A may be
+ * returned after the buffer for request 6 for stream B is. And it is
+ * acceptable that the result metadata for request 6 for stream B is
+ * returned before the buffer for request 5 for stream A is. If multiple
+ * capture results are included in a single call, camera framework must
+ * process results sequentially from lower index to higher index, as if
+ * these results were sent to camera framework one by one, from lower index
+ * to higher index.
+ *
+ * The HAL retains ownership of result structure, which only needs to be
+ * valid to access during this call.
+ *
+ * The output buffers do not need to be filled yet; the framework must wait
+ * on the stream buffer release sync fence before reading the buffer
+ * data. Therefore, this method should be called by the HAL as soon as
+ * possible, even if some or all of the output buffers are still in
+ * being filled. The HAL must include valid release sync fences into each
+ * output_buffers stream buffer entry, or -1 if that stream buffer is
+ * already filled.
+ *
+ * If the result buffer cannot be constructed for a request, the HAL must
+ * return an empty metadata buffer, but still provide the output buffers and
+ * their sync fences. In addition, notify() must be called with an
+ * ERROR_RESULT message.
+ *
+ * If an output buffer cannot be filled, its status field must be set to
+ * STATUS_ERROR. In addition, notify() must be called with a ERROR_BUFFER
+ * message.
+ *
+ * If the entire capture has failed, then this method still needs to be
+ * called to return the output buffers to the framework. All the buffer
+ * statuses must be STATUS_ERROR, and the result metadata must be an
+ * empty buffer. In addition, notify() must be called with a ERROR_REQUEST
+ * message. In this case, individual ERROR_RESULT/ERROR_BUFFER messages
+ * must not be sent.
+ *
+ * Performance requirements:
+ *
+ * This is a non-blocking call. The framework must handle each CaptureResult
+ * within 5ms.

+ * Nevertheless, the HAL device should attempt to minimize the
+ * reconfiguration delay to minimize the user-visible pauses during

+ * held at the time of flush() (whether successfully filled or not) may be
+ * returned with CAMERA3_BUFFER_STATUS_ERROR. Note the HAL is still allowed
+ * to return valid (CAMERA3_BUFFER_STATUS_OK) buffers during this call,
+ * provided they are successfully filled.
+ *
+ * All requests currently in the HAL are expected to be returned as soon as
+ * possible. Not-in-process requests must return errors immediately. Any
+ * interruptible hardware blocks must be stopped, and any uninterruptible
+ * blocks must be waited on.
+ *
+ * flush() may be called concurrently to processCaptureRequest(), with the
+ * expectation that processCaptureRequest returns quickly and the
+ * request submitted in that processCaptureRequest call is treated like
+ * all other in-flight requests. Due to concurrency issues, it is possible
+ * that from the HAL's point of view, a processCaptureRequest() call may
+ * be started after flush has been invoked but has not returned yet. If such
+ * a call happens before flush() returns, the HAL must treat the new
+ * capture request like other in-flight pending requests (see #4 below).
+ *
+ * More specifically, the HAL must follow below requirements for various
+ * cases:
+ *
+ * 1. For captures that are too late for the HAL to cancel/stop, and must be
+ * completed normally by the HAL; i.e. the HAL can send shutter/notify
+ * and processCaptureResult and buffers as normal.
+ *
+ * 2. For pending requests that have not done any processing, the HAL must
+ * call notify CAMERA3_MSG_ERROR_REQUEST, and return all the output
+ * buffers with processCaptureResult in the error state
+ * (CAMERA3_BUFFER_STATUS_ERROR). The HAL must not place the release
+ * fence into an error state, instead, the release fences must be set to
+ * the acquire fences passed by the framework, or -1 if they have been
+ * waited on by the HAL already. This is also the path to follow for any
+ * captures for which the HAL already called notify() with
+ * CAMERA3_MSG_SHUTTER but won't be producing any metadata/valid buffers
+ * for. After CAMERA3_MSG_ERROR_REQUEST, for a given frame, only
+ * processCaptureResults with buffers in CAMERA3_BUFFER_STATUS_ERROR
+ * are allowed. No further notifys or processCaptureResult with
+ * non-empty metadata is allowed.
+ *
+ * 3. For partially completed pending requests that do not have all the
+ * output buffers or perhaps missing metadata, the HAL must follow
+ * below:
+ *
+ * 3.1. Call notify with CAMERA3_MSG_ERROR_RESULT if some of the expected
+ * result metadata (i.e. one or more partial metadata) won't be
+ * available for the capture.
+ *
+ * 3.2. Call notify with CAMERA3_MSG_ERROR_BUFFER for every buffer that
+ * won't be produced for the capture.
+ *
+ * 3.3. Call notify with CAMERA3_MSG_SHUTTER with the capture timestamp
+ * before any buffers/metadata are returned with
+ * processCaptureResult.
+ *
+ * 3.4. For captures that will produce some results, the HAL must not
+ * call CAMERA3_MSG_ERROR_REQUEST, since that indicates complete
+ * failure.
+ *
+ * 3.5. Valid buffers/metadata must be passed to the framework as
+ * normal.
+ *
+ * 3.6. Failed buffers must be returned to the framework as described
+ * for case 2. But failed buffers do not have to follow the strict
+ * ordering valid buffers do, and may be out-of-order with respect
+ * to valid buffers. For example, if buffers A, B, C, D, E are sent,
+ * D and E are failed, then A, E, B, D, C is an acceptable return
+ * order.
+ *
+ * 3.7. For fully-missing metadata, calling CAMERA3_MSG_ERROR_RESULT is
+ * sufficient, no need to call processCaptureResult with empty
+ * metadata or equivalent.
+ *
+ * 4. If a flush() is invoked while a processCaptureRequest() invocation
+ * is active, that process call must return as soon as possible. In
+ * addition, if a processCaptureRequest() call is made after flush()
+ * has been invoked but before flush() has returned, the capture request
+ * provided by the late processCaptureRequest call must be treated
+ * like a pending request in case #2 above.
+ *
+ * flush() must only return when there are no more outstanding buffers or
+ * requests left in the HAL. The framework may call configure_streams (as
+ * the HAL state is now quiesced) or may issue new requests.
+ *
+ * Note that it's sufficient to only support fully-succeeded and
+ * fully-failed result cases. However, it is highly desirable to support
+ * the partial failure cases as well, as it could help improve the flush
+ * call overall performance.
+ *
+ * Performance requirements:
+ *
+ * The HAL should return from this call in 100ms, and must return from this
+ * call in 1000ms. And this call must not be blocked longer than pipeline
+ * latency (see S7 for definition).

+ * max batch size requirements defined by

+ * 5. In this mode, the HAL must override aeMode, awbMode, and afMode to
+ * ON, ON, and CONTINUOUS_VIDEO, respectively. All post-processing
+ * block mode controls must be overridden to be FAST. Therefore, no
+ * manual control of capture and post-processing parameters is

+## Camera Device HAL ##
+---
+
+## Overview: ##
+
+The camera.device HAL interface is used by the Android camera service to operate
+individual camera devices. Instances of camera.device HAL interface can be obtained
+via one of the ICameraProvider::getCameraDeviceInterface_V<N>_x() methods, where N
+is the major version of the camera device interface.
+
+Obtaining the device interface does not turn on the respective camera device;
+each camera device interface has an actual open() method to begin an active
+camera session. Without invoking open(), the interface can be used for querying
+camera static information.
+
+More complete information about the Android camera HAL and subsystem can be found at
+[source.android.com](http://source.android.com/devices/camera/index.html).
+
+## Version history: ##
+
+### ICameraDevice.hal@1.0:
+
+HIDL version of the legacy camera device HAL. Intended as a shim for devices
+needing to use the deprecated pre-HIDL camera device HAL v1.0.
+
+May be used in HIDL passthrough mode for devices upgrading to the Android O
+release; must be used in binderized mode for devices launching in the O release.
+
+It is strongly recommended to not use this interface for new devices, as new
+devices may not use this interface starting with the Android P release, and all
+support for ICameraDevice@1.0 will be removed with the Android R release.
+
+This HAL interface version only allows support at the LEGACY level for the
+android.hardware.camera2 API.
+
+Subsidiary HALs:
+
+#### ICameraDevice1PreviewCallback.hal@1.0:
+
+Callback interface for obtaining, filling, and returning graphics buffers for
+preview operation with the ICameraDevice@1.0 inteface.
+
+#### ICameraDevice1Callback.hal@1.0:
+
+Callback interface for sending events and data buffers from the HAL to the
+camera service.
+
+### ICameraDevice.hal@3.2:
+
+HIDL version of the baseline camera device HAL, required for LIMITED or FULL
+operation through the android.hardware.camera2 API.
+
+The main HAL contains methods for static queries about the device, similar to
+the HALv3-specific sections of the legacy camera module HAL. Simply obtaining an
+instance of the camera device interface does not turn on the camera device.
+
+May be used in passthrough mode for devices upgrading to the Android O release;
+must be used in binderized mode for all new devices launching with Android O or
+later.
+
+The open() method actually opens the camera device for use, returning a Session
+interface for operating the active camera. It takes a Callback interface as an
+argument.
+
+Subsidiary HALs:
+
+#### ICameraDevice3Session.hal@3.2:
+
+Closely matches the features and operation of the pre-HIDL camera device HAL
+v3.2, containing methods for configuring an active camera device and submitting
+capture requests to it.
+
+#### ICameraDevice3Callback.hal@3.2:
+
+Callback interface for sending completed captures and other asynchronous events
+from tehe HAL to the client.

+do additional processing but <a href="#controls_android.colorCorrection.gains">android.<wbr/>color<wbr/>Correction.<wbr/>gains</a> and
+<a href="#controls_android.colorCorrection.transform">android.<wbr/>color<wbr/>Correction.<wbr/>transform</a> will still be provided by the
+camera device (in the results) and be roughly correct.<wbr/></p>
+<p>Switching to TRANSFORM_<wbr/>MATRIX and using the data provided from
+FAST or HIGH_<wbr/>QUALITY will yield a picture with the same white point
+as what was produced by the camera device in the earlier frame.<wbr/></p>
+<p>The expected processing pipeline is as follows:</p>
+<p><img alt="White balance processing pipeline" src="images/camera2/metadata/android.colorCorrection.mode/processing_pipeline.png"/></p>
+<p>The white balance is encoded by two values,<wbr/> a 4-channel white-balance
+gain vector (applied in the Bayer domain),<wbr/> and a 3x3 color transform
+matrix (applied after demosaic).<wbr/></p>
+<p>The 4-channel white-balance gains are defined as:</p>
+<pre><code><a href="#controls_android.colorCorrection.gains">android.<wbr/>color<wbr/>Correction.<wbr/>gains</a> = [ R G_<wbr/>even G_<wbr/>odd B ]
+</code></pre>
+<p>where <code>G_<wbr/>even</code> is the gain for green pixels on even rows of the
+output,<wbr/> and <code>G_<wbr/>odd</code> is the gain for green pixels on the odd rows.<wbr/>
+These may be identical for a given camera device implementation; if
+the camera device does not support a separate gain for even/<wbr/>odd green
+channels,<wbr/> it will use the <code>G_<wbr/>even</code> value,<wbr/> and write <code>G_<wbr/>odd</code> equal to
+<code>G_<wbr/>even</code> in the output result metadata.<wbr/></p>
+<p>The matrices for color transforms are defined as a 9-entry vector:</p>
+<pre><code><a href="#controls_android.colorCorrection.transform">android.<wbr/>color<wbr/>Correction.<wbr/>transform</a> = [ I0 I1 I2 I3 I4 I5 I6 I7 I8 ]
+</code></pre>
+<p>which define a transform from input sensor colors,<wbr/> <code>P_<wbr/>in = [ r g b ]</code>,<wbr/>
+to output linear sRGB,<wbr/> <code>P_<wbr/>out = [ r' g' b' ]</code>,<wbr/></p>
+<p>with colors as follows:</p>
+<pre><code>r' = I0r + I1g + I2b
+g' = I3r + I4g + I5b
+b' = I6r + I7g + I8b
+</code></pre>
+<p>Both the input and output value ranges must match.<wbr/> Overflow/<wbr/>underflow

+CANCEL trigger will unlock the AE and return to its initial AE state.<wbr/></p>
+<p>The precapture sequence should be triggered before starting a
+high-quality still capture for final metering decisions to
+be made,<wbr/> and for firing pre-capture flash pulses to estimate
+scene brightness and required final capture flash power,<wbr/> when
+the flash is enabled.<wbr/></p>
+<p>Normally,<wbr/> this entry should be set to START for only a
+single request,<wbr/> and the application should wait until the
+sequence completes before starting a new one.<wbr/></p>
+<p>When a precapture metering sequence is finished,<wbr/> the camera device
+may lock the auto-exposure routine internally to be able to accurately expose the
+subsequent still capture image (<code><a href="#controls_android.control.captureIntent">android.<wbr/>control.<wbr/>capture<wbr/>Intent</a> == STILL_<wbr/>CAPTURE</code>).<wbr/>
+For this case,<wbr/> the AE may not resume normal scan if no subsequent still capture is
+submitted.<wbr/> To ensure that the AE routine restarts normal scan,<wbr/> the application should
+submit a request with <code><a href="#controls_android.control.aeLock">android.<wbr/>control.<wbr/>ae<wbr/>Lock</a> == true</code>,<wbr/> followed by a request
+with <code><a href="#controls_android.control.aeLock">android.<wbr/>control.<wbr/>ae<wbr/>Lock</a> == false</code>,<wbr/> if the application decides not to submit a
+still capture request after the precapture sequence completes.<wbr/> Alternatively,<wbr/> for
+API level 23 or newer devices,<wbr/> the CANCEL can be used to unlock the camera device
+internally locked AE if the application doesn't submit a still capture request after
+the AE precapture trigger.<wbr/> Note that,<wbr/> the CANCEL was added in API level 23,<wbr/> and must not
+be used in devices that have earlier API levels.<wbr/></p>
+<p>The exact effect of auto-exposure (AE) precapture trigger
+depends on the current AE mode and state; see

+details.<wbr/></p>
+<p>On LEGACY-level devices,<wbr/> the precapture trigger is not supported;
+capturing a high-resolution JPEG image will automatically trigger a
+precapture sequence before the high-resolution capture,<wbr/> including
+potentially firing a pre-capture flash.<wbr/></p>
+<p>Using the precapture trigger and the auto-focus trigger <a href="#controls_android.control.afTrigger">android.<wbr/>control.<wbr/>af<wbr/>Trigger</a>
+simultaneously is allowed.<wbr/> However,<wbr/> since these triggers often require cooperation between
+the auto-focus and auto-exposure routines (for example,<wbr/> the may need to be enabled for a
+focus sweep),<wbr/> the camera device may delay acting on a later trigger until the previous
+trigger has been fully handled.<wbr/> This may lead to longer intervals between the trigger and
+changes to <a href="#dynamic_android.control.aeState">android.<wbr/>control.<wbr/>ae<wbr/>State</a> indicating the start of the precapture sequence,<wbr/> for

+<p>The coordinate system is based on the active pixel array,<wbr/>

+<p>The weight must be within <code>[0,<wbr/> 1000]</code>,<wbr/> and represents a weight
+for every pixel in the area.<wbr/> This means that a large metering area
+with the same weight as a smaller area will have more effect in
+the metering result.<wbr/> Metering areas can partially overlap and the
+camera device will add the weights in the overlap region.<wbr/></p>
+<p>The weights are relative to weights of other metering regions,<wbr/> so if only one region
+is used,<wbr/> all non-zero weights will have the same effect.<wbr/> A region with 0 weight is
+ignored.<wbr/></p>
+<p>If all regions have 0 weight,<wbr/> then no specific metering area needs to be used by the

+<p>If the metering region is outside the used <a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a> returned in

+ <span class="entry_type_enum_notes"><p>Turn on a device-specific high dynamic range (HDR) mode.<wbr/></p>
+<p>In this scene mode,<wbr/> the camera device captures images
+that keep a larger range of scene illumination levels
+visible in the final image.<wbr/> For example,<wbr/> when taking a
+picture of a object in front of a bright window,<wbr/> both
+the object and the scene through the window may be
+visible when using HDR mode,<wbr/> while in normal AUTO mode,<wbr/>
+one or the other may be poorly exposed.<wbr/> As a tradeoff,<wbr/>
+HDR mode generally takes much longer to capture a single
+image,<wbr/> has no user control,<wbr/> and may have other artifacts
+depending on the HDR method used.<wbr/></p>
+<p>Therefore,<wbr/> HDR captures operate at a much slower rate
+than regular captures.<wbr/></p>
+<p>In this mode,<wbr/> on LIMITED or FULL devices,<wbr/> when a request
+is made with a <a href="#controls_android.control.captureIntent">android.<wbr/>control.<wbr/>capture<wbr/>Intent</a> of
+STILL_<wbr/>CAPTURE,<wbr/> the camera device will capture an image
+using a high dynamic range capture technique.<wbr/> On LEGACY
+devices,<wbr/> captures that target a JPEG-format output will
+be captured with HDR,<wbr/> and the capture intent is not
+relevant.<wbr/></p>
+<p>The HDR capture may involve the device capturing a burst
+of images internally and combining them into one,<wbr/> or it
+may involve the device using specialized high dynamic
+range capture hardware.<wbr/> In all cases,<wbr/> a single image is
+produced in response to a capture request submitted
+while in HDR mode.<wbr/></p>
+<p>Since substantial post-processing is generally needed to
+produce an HDR image,<wbr/> only YUV,<wbr/> PRIVATE,<wbr/> and JPEG
+outputs are supported for LIMITED/<wbr/>FULL device HDR
+captures,<wbr/> and only JPEG outputs are supported for LEGACY
+HDR captures.<wbr/> Using a RAW output for HDR capture is not
+supported.<wbr/></p>
+<p>Some devices may also support always-on HDR,<wbr/> which
+applies HDR processing at full frame rate.<wbr/> For these
+devices,<wbr/> intents other than STILL_<wbr/>CAPTURE will also
+produce an HDR output with no frame rate impact compared
+to normal operation,<wbr/> though the quality may be lower
+than for STILL_<wbr/>CAPTURE intents.<wbr/></p>
+<p>If SCENE_<wbr/>MODE_<wbr/>HDR is used with unsupported output types
+or capture intents,<wbr/> the images captured will be as if
+the SCENE_<wbr/>MODE was not enabled at all.<wbr/></p></span>

+under low light conditions.<wbr/></p>
+<p>The camera device may be tuned to expose the images in a reduced
+sensitivity range to produce the best quality images.<wbr/> For example,<wbr/>
+if the <a href="#static_android.sensor.info.sensitivityRange">android.<wbr/>sensor.<wbr/>info.<wbr/>sensitivity<wbr/>Range</a> gives range of [100,<wbr/> 1600],<wbr/>
+the camera device auto-exposure routine tuning process may limit the actual
+exposure sensitivity range to [100,<wbr/> 1200] to ensure that the noise level isn't
+exessive in order to preserve the image quality.<wbr/> Under this situation,<wbr/> the image under
+low light may be under-exposed when the sensor max exposure time (bounded by the
+<a href="#controls_android.control.aeTargetFpsRange">android.<wbr/>control.<wbr/>ae<wbr/>Target<wbr/>Fps<wbr/>Range</a> when <a href="#controls_android.control.aeMode">android.<wbr/>control.<wbr/>ae<wbr/>Mode</a> is one of the
+ON_<wbr/>* modes) and effective max sensitivity are reached.<wbr/> This scene mode allows the
+camera device auto-exposure routine to increase the sensitivity up to the max
+sensitivity specified by <a href="#static_android.sensor.info.sensitivityRange">android.<wbr/>sensor.<wbr/>info.<wbr/>sensitivity<wbr/>Range</a> when the scene is too
+dark and the max exposure time is reached.<wbr/> The captured images may be noisier
+compared with the images captured in normal FACE_<wbr/>PRIORITY mode; therefore,<wbr/> it is

+<p>For the high speed video use case,<wbr/> the application must

+configure output streams.<wbr/> Once the size is selected,<wbr/> application can filter this metadata
+by selected size and get the supported fps ranges,<wbr/> and use these fps ranges to setup the

+must select one unique size from this metadata to use (e.<wbr/>g.,<wbr/> preview and recording streams

+<p>The min and max fps will be multiple times of 30fps.<wbr/></p>
+<p>High speed video streaming extends significant performance pressue to camera hardware,<wbr/>
+to achieve efficient high speed streaming,<wbr/> the camera device may have to aggregate
+multiple frames together and send to camera device for processing where the request
+controls are same for all the frames in this batch.<wbr/> Max batch size indicates
+the max possible number of frames the camera device will group together for this high
+speed stream configuration.<wbr/> This max batch size will be used to generate a high speed
+recording request list by
+<a href="https://developer.android.com/reference/android/hardware/camera2/CameraConstrainedHighSpeedCaptureSession.html#createHighSpeedRequestList">CameraConstrainedHighSpeedCaptureSession#createHighSpeedRequestList</a>.<wbr/>
+The max batch size for each configuration will satisfy below conditions:</p>
+<ul>
+<li>Each max batch size will be a divisor of its corresponding fps_<wbr/>max /<wbr/> 30.<wbr/> For example,<wbr/>
+if max_<wbr/>fps is 300,<wbr/> max batch size will only be 1,<wbr/> 2,<wbr/> 5,<wbr/> or 10.<wbr/></li>
+<li>The camera device may choose smaller internal batch size for each configuration,<wbr/> but
+the actual batch size will be a divisor of max batch size.<wbr/> For example,<wbr/> if the max batch
+size is 8,<wbr/> the actual batch size used by camera device will only be 1,<wbr/> 2,<wbr/> 4,<wbr/> or 8.<wbr/></li>
+<li>The max batch size in each configuration entry must be no larger than 32.<wbr/></li>
+</ul>
+<p>The camera device doesn't have to support batch mode to achieve high speed video recording,<wbr/>
+in such case,<wbr/> batch_<wbr/>size_<wbr/>max will be reported as 1 in each configuration entry.<wbr/></p>
+<p>This fps ranges in this configuration list can only be used to create requests

+usually starts preview first,<wbr/> then starts recording.<wbr/> To avoid sensor mode switch caused
+stutter when starting recording as much as possible,<wbr/> the application may want to ensure
+the same sensor mode is used for preview and recording.<wbr/> Therefore,<wbr/> The HAL must advertise
+the variable fps range [30,<wbr/> fps_<wbr/>max] for each fixed fps range in this configuration list.<wbr/>
+For example,<wbr/> if the HAL advertises [120,<wbr/> 120] and [240,<wbr/> 240],<wbr/> the HAL must also advertise
+[30,<wbr/> 120] and [30,<wbr/> 240] for each configuration.<wbr/> In doing so,<wbr/> if the application intends to

+recording.<wbr/> For these variable fps ranges,<wbr/> it's up to the HAL to decide the actual fps
+values that are suitable for smooth preview streaming.<wbr/> If the HAL sees different max_<wbr/>fps
+values that fall into different sensor modes in a sequence of requests,<wbr/> the HAL must

+ <p>This entry is normally set to IDLE,<wbr/> or is not
+included at all in the request settings.<wbr/> When included and
+set to START,<wbr/> the camera device will trigger the auto-exposure (AE)
+precapture metering sequence.<wbr/></p>
+<p>When set to CANCEL,<wbr/> the camera device will cancel any active
+precapture metering trigger,<wbr/> and return to its initial AE state.<wbr/>
+If a precapture metering sequence is already completed,<wbr/> and the camera
+device has implicitly locked the AE for subsequent still capture,<wbr/> the
+CANCEL trigger will unlock the AE and return to its initial AE state.<wbr/></p>
+<p>The precapture sequence should be triggered before starting a
+high-quality still capture for final metering decisions to
+be made,<wbr/> and for firing pre-capture flash pulses to estimate
+scene brightness and required final capture flash power,<wbr/> when
+the flash is enabled.<wbr/></p>
+<p>Normally,<wbr/> this entry should be set to START for only a
+single request,<wbr/> and the application should wait until the
+sequence completes before starting a new one.<wbr/></p>
+<p>When a precapture metering sequence is finished,<wbr/> the camera device
+may lock the auto-exposure routine internally to be able to accurately expose the
+subsequent still capture image (<code><a href="#controls_android.control.captureIntent">android.<wbr/>control.<wbr/>capture<wbr/>Intent</a> == STILL_<wbr/>CAPTURE</code>).<wbr/>
+For this case,<wbr/> the AE may not resume normal scan if no subsequent still capture is
+submitted.<wbr/> To ensure that the AE routine restarts normal scan,<wbr/> the application should
+submit a request with <code><a href="#controls_android.control.aeLock">android.<wbr/>control.<wbr/>ae<wbr/>Lock</a> == true</code>,<wbr/> followed by a request
+with <code><a href="#controls_android.control.aeLock">android.<wbr/>control.<wbr/>ae<wbr/>Lock</a> == false</code>,<wbr/> if the application decides not to submit a
+still capture request after the precapture sequence completes.<wbr/> Alternatively,<wbr/> for
+API level 23 or newer devices,<wbr/> the CANCEL can be used to unlock the camera device
+internally locked AE if the application doesn't submit a still capture request after
+the AE precapture trigger.<wbr/> Note that,<wbr/> the CANCEL was added in API level 23,<wbr/> and must not
+be used in devices that have earlier API levels.<wbr/></p>
+<p>The exact effect of auto-exposure (AE) precapture trigger
+depends on the current AE mode and state; see
+<a href="#dynamic_android.control.aeState">android.<wbr/>control.<wbr/>ae<wbr/>State</a> for AE precapture state transition
+details.<wbr/></p>
+<p>On LEGACY-level devices,<wbr/> the precapture trigger is not supported;
+capturing a high-resolution JPEG image will automatically trigger a
+precapture sequence before the high-resolution capture,<wbr/> including
+potentially firing a pre-capture flash.<wbr/></p>
+<p>Using the precapture trigger and the auto-focus trigger <a href="#controls_android.control.afTrigger">android.<wbr/>control.<wbr/>af<wbr/>Trigger</a>
+simultaneously is allowed.<wbr/> However,<wbr/> since these triggers often require cooperation between
+the auto-focus and auto-exposure routines (for example,<wbr/> the may need to be enabled for a
+focus sweep),<wbr/> the camera device may delay acting on a later trigger until the previous
+trigger has been fully handled.<wbr/> This may lead to longer intervals between the trigger and
+changes to <a href="#dynamic_android.control.aeState">android.<wbr/>control.<wbr/>ae<wbr/>State</a> indicating the start of the precapture sequence,<wbr/> for
+example.<wbr/></p>
+<p>If both the precapture and the auto-focus trigger are activated on the same request,<wbr/> then
+the camera device will complete them in the optimal order for that device.<wbr/></p>

+up with either FOCUSED_<wbr/>LOCKED or NOT_<wbr/>FOCUSED_<wbr/>LOCKED state (see
+<a href="#dynamic_android.control.afState">android.<wbr/>control.<wbr/>af<wbr/>State</a> for detailed state transitions),<wbr/> which indicates that the lens is
+locked and will not move.<wbr/> If camera movement (e.<wbr/>g.<wbr/> tilting camera) causes the lens to move
+after the lens is locked,<wbr/> the HAL must compensate this movement appropriately such that
+the same focal plane remains in focus.<wbr/></p>
+<p>When afMode is one of the continuous auto focus modes,<wbr/> the HAL is free to start a AF
+scan whenever it's not locked.<wbr/> When the lens is locked after an AF trigger
+(see <a href="#dynamic_android.control.afState">android.<wbr/>control.<wbr/>af<wbr/>State</a> for detailed state transitions),<wbr/> the HAL should maintain the
+same lock behavior as above.<wbr/></p>
+<p>When afMode is OFF,<wbr/> the application controls focus manually.<wbr/> The accuracy of the
+focus distance control depends on the <a href="#static_android.lens.info.focusDistanceCalibration">android.<wbr/>lens.<wbr/>info.<wbr/>focus<wbr/>Distance<wbr/>Calibration</a>.<wbr/>
+However,<wbr/> the lens must not move regardless of the camera movement for any focus distance
+manual control.<wbr/></p>
+<p>To put this in concrete terms,<wbr/> if the camera has lens elements which may move based on
+camera orientation or motion (e.<wbr/>g.<wbr/> due to gravity),<wbr/> then the HAL must drive the lens to
+remain in a fixed position invariant to the camera's orientation or motion,<wbr/> for example,<wbr/>
+by using accelerometer measurements in the lens control logic.<wbr/> This is a typical issue
+that will arise on camera modules with open-loop VCMs.<wbr/></p>

+<p>In this scene mode,<wbr/> the camera device captures images
+that keep a larger range of scene illumination levels
+visible in the final image.<wbr/> For example,<wbr/> when taking a
+picture of a object in front of a bright window,<wbr/> both
+the object and the scene through the window may be
+visible when using HDR mode,<wbr/> while in normal AUTO mode,<wbr/>
+one or the other may be poorly exposed.<wbr/> As a tradeoff,<wbr/>
+HDR mode generally takes much longer to capture a single
+image,<wbr/> has no user control,<wbr/> and may have other artifacts
+depending on the HDR method used.<wbr/></p>
+<p>Therefore,<wbr/> HDR captures operate at a much slower rate
+than regular captures.<wbr/></p>
+<p>In this mode,<wbr/> on LIMITED or FULL devices,<wbr/> when a request
+is made with a <a href="#controls_android.control.captureIntent">android.<wbr/>control.<wbr/>capture<wbr/>Intent</a> of
+STILL_<wbr/>CAPTURE,<wbr/> the camera device will capture an image
+using a high dynamic range capture technique.<wbr/> On LEGACY
+devices,<wbr/> captures that target a JPEG-format output will
+be captured with HDR,<wbr/> and the capture intent is not
+relevant.<wbr/></p>
+<p>The HDR capture may involve the device capturing a burst
+of images internally and combining them into one,<wbr/> or it
+may involve the device using specialized high dynamic
+range capture hardware.<wbr/> In all cases,<wbr/> a single image is
+produced in response to a capture request submitted
+while in HDR mode.<wbr/></p>
+<p>Since substantial post-processing is generally needed to
+produce an HDR image,<wbr/> only YUV,<wbr/> PRIVATE,<wbr/> and JPEG
+outputs are supported for LIMITED/<wbr/>FULL device HDR
+captures,<wbr/> and only JPEG outputs are supported for LEGACY
+HDR captures.<wbr/> Using a RAW output for HDR capture is not
+supported.<wbr/></p>
+<p>Some devices may also support always-on HDR,<wbr/> which
+applies HDR processing at full frame rate.<wbr/> For these
+devices,<wbr/> intents other than STILL_<wbr/>CAPTURE will also
+produce an HDR output with no frame rate impact compared
+to normal operation,<wbr/> though the quality may be lower
+than for STILL_<wbr/>CAPTURE intents.<wbr/></p>
+<p>If SCENE_<wbr/>MODE_<wbr/>HDR is used with unsupported output types
+or capture intents,<wbr/> the images captured will be as if

+ <p>OIS is used to compensate for motion blur due to small
+movements of the camera during capture.<wbr/> Unlike digital image
+stabilization (<a href="#controls_android.control.videoStabilizationMode">android.<wbr/>control.<wbr/>video<wbr/>Stabilization<wbr/>Mode</a>),<wbr/> OIS
+makes use of mechanical elements to stabilize the camera
+sensor,<wbr/> and thus allows for longer exposure times before
+camera shake becomes apparent.<wbr/></p>
+<p>Switching between different optical stabilization modes may take several
+frames to initialize,<wbr/> the camera device will report the current mode in
+capture result metadata.<wbr/> For example,<wbr/> When "ON" mode is requested,<wbr/> the
+optical stabilization modes in the first several capture results may still
+be "OFF",<wbr/> and it will become "ON" when the initialization is done.<wbr/></p>

+</ul>
+<p>For high speed recording use case,<wbr/> the actual maximum supported frame rate may

+high frame rate for a given video size,<wbr/> or it will end up with lower recording
+frame rate.<wbr/> If the destination surface is from preview window,<wbr/> the actual preview frame
+rate will be bounded by the screen refresh rate.<wbr/></p>
+<p>The camera device will only support up to 2 high speed simultaneous output surfaces
+(preview and recording surfaces)

+<a href="https://developer.android.com/reference/android/hardware/camera2/CameraDevice.html#createConstrainedHighSpeedCaptureSession">CameraDevice#createConstrainedHighSpeedCaptureSession</a>.<wbr/> The

+<a href="https://developer.android.com/reference/android/hardware/camera2/CameraDevice.html#createConstrainedHighSpeedCaptureSession">CameraDevice#createConstrainedHighSpeedCaptureSession</a>

+<p>Switching to a FPS range that has different maximum FPS may trigger some camera device

+ <p>A stall duration is how much extra time would get added
+to the normal minimum frame duration for a repeating request
+that has streams with non-zero stall.<wbr/></p>
+<p>For example,<wbr/> consider JPEG captures which have the following
+characteristics:</p>
+<ul>
+<li>JPEG streams act like processed YUV streams in requests for which
+they are not included; in requests in which they are directly
+referenced,<wbr/> they act as JPEG streams.<wbr/> This is because supporting a
+JPEG stream requires the underlying YUV data to always be ready for
+use by a JPEG encoder,<wbr/> but the encoder will only be used (and impact
+frame duration) on requests that actually reference a JPEG stream.<wbr/></li>
+<li>The JPEG processor can run concurrently to the rest of the camera
+pipeline,<wbr/> but cannot process more than 1 capture at a time.<wbr/></li>
+</ul>
+<p>In other words,<wbr/> using a repeating YUV request would result
+in a steady frame rate (let's say it's 30 FPS).<wbr/> If a single
+JPEG request is submitted periodically,<wbr/> the frame rate will stay
+at 30 FPS (as long as we wait for the previous JPEG to return each
+time).<wbr/> If we try to submit a repeating YUV + JPEG request,<wbr/> then
+the frame rate will drop from 30 FPS.<wbr/></p>
+<p>In general,<wbr/> submitting a new request with a non-0 stall time
+stream will <em>not</em> cause a frame rate drop unless there are still
+outstanding buffers for that stream from previous requests.<wbr/></p>
+<p>Submitting a repeating request with streams (call this <code>S</code>)
+is the same as setting the minimum frame duration from
+the normal minimum frame duration corresponding to <code>S</code>,<wbr/> added with
+the maximum stall duration for <code>S</code>.<wbr/></p>
+<p>If interleaving requests with and without a stall duration,<wbr/>
+a request will stall by the maximum of the remaining times
+for each can-stall stream with outstanding buffers.<wbr/></p>
+<p>This means that a stalling request will not have an exposure start
+until the stall has completed.<wbr/></p>
+<p>This should correspond to the stall duration when only that stream is
+active,<wbr/> with all processing (typically in android.<wbr/>*.<wbr/>mode) set to FAST
+or OFF.<wbr/> Setting any of the processing modes to HIGH_<wbr/>QUALITY
+effectively results in an indeterminate stall duration for all
+streams in a request (the regular stall calculation rules are
+ignored).<wbr/></p>
+<p>The following formats may always have a stall duration:</p>
+<ul>
+<li><a href="https://developer.android.com/reference/android/graphics/ImageFormat.html#JPEG">ImageFormat#JPEG</a></li>
+<li><a href="https://developer.android.com/reference/android/graphics/ImageFormat.html#RAW_SENSOR">ImageFormat#RAW_<wbr/>SENSOR</a></li>
+</ul>

+ <p>The maximum frame rate that can be supported by a camera subsystem is
+a function of many factors:</p>
+<ul>
+<li>Requested resolutions of output image streams</li>
+<li>Availability of binning /<wbr/> skipping modes on the imager</li>
+<li>The bandwidth of the imager interface</li>
+<li>The bandwidth of the various ISP processing blocks</li>
+</ul>
+<p>Since these factors can vary greatly between different ISPs and
+sensors,<wbr/> the camera abstraction tries to represent the bandwidth
+restrictions with as simple a model as possible.<wbr/></p>
+<p>The model presented has the following characteristics:</p>
+<ul>
+<li>The image sensor is always configured to output the smallest
+resolution possible given the application's requested output stream
+sizes.<wbr/> The smallest resolution is defined as being at least as large
+as the largest requested output stream size; the camera pipeline must
+never digitally upsample sensor data when the crop region covers the
+whole sensor.<wbr/> In general,<wbr/> this means that if only small output stream
+resolutions are configured,<wbr/> the sensor can provide a higher frame
+rate.<wbr/></li>
+<li>Since any request may use any or all the currently configured
+output streams,<wbr/> the sensor and ISP must be configured to support
+scaling a single capture to all the streams at the same time.<wbr/> This
+means the camera pipeline must be ready to produce the largest
+requested output size without any delay.<wbr/> Therefore,<wbr/> the overall
+frame rate of a given configured stream set is governed only by the
+largest requested stream resolution.<wbr/></li>
+<li>Using more than one output stream in a request does not affect the
+frame duration.<wbr/></li>
+<li>Certain format-streams may need to do additional background processing
+before data is consumed/<wbr/>produced by that stream.<wbr/> These processors
+can run concurrently to the rest of the camera pipeline,<wbr/> but
+cannot process more than 1 capture at a time.<wbr/></li>
+</ul>
+<p>The necessary information for the application,<wbr/> given the model above,<wbr/>
+is provided via the <a href="#static_android.scaler.streamConfigurationMap">android.<wbr/>scaler.<wbr/>stream<wbr/>Configuration<wbr/>Map</a> field using
+<a href="https://developer.android.com/reference/android/hardware/camera2/params/StreamConfigurationMap.html#getOutputMinFrameDuration">StreamConfigurationMap#getOutputMinFrameDuration</a>.<wbr/>
+These are used to determine the maximum frame rate /<wbr/> minimum frame
+duration that is possible for a given stream configuration.<wbr/></p>
+<p>Specifically,<wbr/> the application can use the following rules to
+determine the minimum frame duration it can request from the camera
+device:</p>
+<ol>
+<li>Let the set of currently configured input/<wbr/>output streams
+be called <code>S</code>.<wbr/></li>
+<li>Find the minimum frame durations for each stream in <code>S</code>,<wbr/> by looking
+it up in <a href="#static_android.scaler.streamConfigurationMap">android.<wbr/>scaler.<wbr/>stream<wbr/>Configuration<wbr/>Map</a> using <a href="https://developer.android.com/reference/android/hardware/camera2/params/StreamConfigurationMap.html#getOutputMinFrameDuration">StreamConfigurationMap#getOutputMinFrameDuration</a>
+(with its respective size/<wbr/>format).<wbr/> Let this set of frame durations be
+called <code>F</code>.<wbr/></li>
+<li>For any given request <code>R</code>,<wbr/> the minimum frame duration allowed
+for <code>R</code> is the maximum out of all values in <code>F</code>.<wbr/> Let the streams
+used in <code>R</code> be called <code>S_<wbr/>r</code>.<wbr/></li>
+</ol>
+<p>If none of the streams in <code>S_<wbr/>r</code> have a stall time (listed in <a href="https://developer.android.com/reference/android/hardware/camera2/params/StreamConfigurationMap.html#getOutputStallDuration">StreamConfigurationMap#getOutputStallDuration</a>
+using its respective size/<wbr/>format),<wbr/> then the frame duration in <code>F</code>
+determines the steady state frame rate that the application will get
+if it uses <code>R</code> as a repeating request.<wbr/> Let this special kind of
+request be called <code>Rsimple</code>.<wbr/></p>
+<p>A repeating request <code>Rsimple</code> can be <em>occasionally</em> interleaved
+by a single capture of a new request <code>Rstall</code> (which has at least
+one in-use stream with a non-0 stall time) and if <code>Rstall</code> has the
+same minimum frame duration this will not cause a frame rate loss
+if all buffers from the previous <code>Rstall</code> have already been
+delivered.<wbr/></p>

+ <p>The maximum frame rate that can be supported by a camera subsystem is
+a function of many factors:</p>
+<ul>
+<li>Requested resolutions of output image streams</li>
+<li>Availability of binning /<wbr/> skipping modes on the imager</li>
+<li>The bandwidth of the imager interface</li>
+<li>The bandwidth of the various ISP processing blocks</li>
+</ul>
+<p>Since these factors can vary greatly between different ISPs and
+sensors,<wbr/> the camera abstraction tries to represent the bandwidth
+restrictions with as simple a model as possible.<wbr/></p>
+<p>The model presented has the following characteristics:</p>
+<ul>
+<li>The image sensor is always configured to output the smallest
+resolution possible given the application's requested output stream
+sizes.<wbr/> The smallest resolution is defined as being at least as large
+as the largest requested output stream size; the camera pipeline must
+never digitally upsample sensor data when the crop region covers the
+whole sensor.<wbr/> In general,<wbr/> this means that if only small output stream
+resolutions are configured,<wbr/> the sensor can provide a higher frame
+rate.<wbr/></li>
+<li>Since any request may use any or all the currently configured
+output streams,<wbr/> the sensor and ISP must be configured to support
+scaling a single capture to all the streams at the same time.<wbr/> This
+means the camera pipeline must be ready to produce the largest
+requested output size without any delay.<wbr/> Therefore,<wbr/> the overall
+frame rate of a given configured stream set is governed only by the
+largest requested stream resolution.<wbr/></li>
+<li>Using more than one output stream in a request does not affect the
+frame duration.<wbr/></li>
+<li>Certain format-streams may need to do additional background processing
+before data is consumed/<wbr/>produced by that stream.<wbr/> These processors
+can run concurrently to the rest of the camera pipeline,<wbr/> but
+cannot process more than 1 capture at a time.<wbr/></li>
+</ul>
+<p>The necessary information for the application,<wbr/> given the model above,<wbr/>
+is provided via the <a href="#static_android.scaler.streamConfigurationMap">android.<wbr/>scaler.<wbr/>stream<wbr/>Configuration<wbr/>Map</a> field using
+<a href="https://developer.android.com/reference/android/hardware/camera2/params/StreamConfigurationMap.html#getOutputMinFrameDuration">StreamConfigurationMap#getOutputMinFrameDuration</a>.<wbr/>
+These are used to determine the maximum frame rate /<wbr/> minimum frame
+duration that is possible for a given stream configuration.<wbr/></p>
+<p>Specifically,<wbr/> the application can use the following rules to
+determine the minimum frame duration it can request from the camera
+device:</p>
+<ol>
+<li>Let the set of currently configured input/<wbr/>output streams
+be called <code>S</code>.<wbr/></li>
+<li>Find the minimum frame durations for each stream in <code>S</code>,<wbr/> by looking
+it up in <a href="#static_android.scaler.streamConfigurationMap">android.<wbr/>scaler.<wbr/>stream<wbr/>Configuration<wbr/>Map</a> using <a href="https://developer.android.com/reference/android/hardware/camera2/params/StreamConfigurationMap.html#getOutputMinFrameDuration">StreamConfigurationMap#getOutputMinFrameDuration</a>
+(with its respective size/<wbr/>format).<wbr/> Let this set of frame durations be
+called <code>F</code>.<wbr/></li>
+<li>For any given request <code>R</code>,<wbr/> the minimum frame duration allowed
+for <code>R</code> is the maximum out of all values in <code>F</code>.<wbr/> Let the streams
+used in <code>R</code> be called <code>S_<wbr/>r</code>.<wbr/></li>
+</ol>
+<p>If none of the streams in <code>S_<wbr/>r</code> have a stall time (listed in <a href="https://developer.android.com/reference/android/hardware/camera2/params/StreamConfigurationMap.html#getOutputStallDuration">StreamConfigurationMap#getOutputStallDuration</a>
+using its respective size/<wbr/>format),<wbr/> then the frame duration in <code>F</code>
+determines the steady state frame rate that the application will get
+if it uses <code>R</code> as a repeating request.<wbr/> Let this special kind of
+request be called <code>Rsimple</code>.<wbr/></p>
+<p>A repeating request <code>Rsimple</code> can be <em>occasionally</em> interleaved
+by a single capture of a new request <code>Rstall</code> (which has at least
+one in-use stream with a non-0 stall time) and if <code>Rstall</code> has the
+same minimum frame duration this will not cause a frame rate loss
+if all buffers from the previous <code>Rstall</code> have already been
+delivered.<wbr/></p>

+map,<wbr/> and an active pixel array size (W x H),<wbr/> shading map entry
+(x,<wbr/>y) ϵ (0 ...<wbr/> N-1,<wbr/> 0 ...<wbr/> M-1) is the value of the shading map at
+pixel ( ((W-1)/<wbr/>(N-1)) * x,<wbr/> ((H-1)/<wbr/>(M-1)) * y) for the four color channels.<wbr/>
+The map is assumed to be bilinearly interpolated between the sample points.<wbr/></p>
+<p>The channel order is [R,<wbr/> Geven,<wbr/> Godd,<wbr/> B],<wbr/> where Geven is the green
+channel for the even rows of a Bayer pattern,<wbr/> and Godd is the odd rows.<wbr/>
+The shading map is stored in a fully interleaved format,<wbr/> and its size
+is provided in the camera static metadata by <a href="#static_android.lens.info.shadingMapSize">android.<wbr/>lens.<wbr/>info.<wbr/>shading<wbr/>Map<wbr/>Size</a>.<wbr/></p>
+<p>The shading map will generally have on the order of 30-40 rows and columns,<wbr/>
+and will be smaller than 64x64.<wbr/></p>

+the following code snippet can be used:</p>
+<pre><code>//<wbr/> Returns true if the device supports the required hardware level,<wbr/> or better.<wbr/>
+boolean isHardwareLevelSupported(CameraCharacteristics c,<wbr/> int requiredLevel) {
+ int deviceLevel = c.<wbr/>get(Camera<wbr/>Characteristics.<wbr/>INFO_<wbr/>SUPPORTED_<wbr/>HARDWARE_<wbr/>LEVEL);

+ return requiredLevel == deviceLevel;
+ }
+ //<wbr/> deviceLevel is not LEGACY,<wbr/> can use numerical sort
+ return requiredLevel <= deviceLevel;
+}
+</code></pre>
+<p>At a high level,<wbr/> the levels are:</p>
+<ul>
+<li><code>LEGACY</code> devices operate in a backwards-compatibility mode for older
+ Android devices,<wbr/> and have very limited capabilities.<wbr/></li>
+<li><code>LIMITED</code> devices represent the
+ baseline feature set,<wbr/> and may also include additional capabilities that are
+ subsets of <code>FULL</code>.<wbr/></li>
+<li><code>FULL</code> devices additionally support per-frame manual control of sensor,<wbr/> flash,<wbr/> lens and
+ post-processing settings,<wbr/> and image capture at a high rate.<wbr/></li>
+<li><code>LEVEL_<wbr/>3</code> devices additionally support YUV reprocessing and RAW image capture,<wbr/> along
+ with additional output stream configurations.<wbr/></li>

+## Camera Metadata Interface ##
+---
+
+## Overview: ##
+
+The camera.metadata interface is used by the Android camera service,
+camera provider and camera devices to retrieve static camera information and issue
+camera capture controls.
+
+See the docs.html for each version for the detailed description of each metadata
+specification.
+## Version history: ##
+
+### @3.2:
+
+HIDL version of the baseline camera metadata interface, required by
+camera.provider@2.4 and camera.device@3.2 onwards.

+ * - <instance> is a non-negative integer starting from 0 to disambiguate
+ * between multiple HALs of the same type.
+ *
+ * The "legacy" type is only used for passthrough legacy HAL mode, and must

+## Camera Provider HAL ##
+---
+
+## Overview: ##
+
+The camera.provider HAL is used by the Android camera service to discover,
+query, and open individual camera devices.
+
+It also allows for direct control of the flash unit of camera devices that have
+one, for turning on/off torch mode.
+
+More complete information about the Android camera HAL and subsystem can be found at
+[source.android.com](http://source.android.com/devices/camera/index.html).
+
+## Version history: ##
+
+## types.hal: ##
+
+### @0.0:
+
+Common enum and struct definitions for all camera HAL interfaces. Does not
+define any interfaces of its own.
+
+## ICameraProvider.hal: ##
+
+### @2.4:
+
+First HIDL version of the camera provider HAL, closely matching the feature set
+and operation of the pre-HIDL camera HAL module v2.4.
+
+## ICameraProviderCallback.hal: ##
+
+### @2.4:
+
+First HIDL version of the camara provider HAL callback interface, closely
+matching the feature set and operation of the pre-HIDL camera HAL module
+callbacks v2.4.

+ * The DRM and Crypto HALs interact with vendor-provided HAL implementations
+ * that have DRM-specific capabilities. Since the VTS tests cannot contain
+ * DRM-specific functionality, supporting modules are required to enable VTS
+ * to validate HAL implementations in a generic way. If the vendor-specific
+ * VTS module is not provided for a given drm HAL implementation, only very
+ * small subset of functionality can be verified.
+ *
+ * As an example, a DRM HAL implementation interacts with a DRM-specific
+ * license server to obtain licenses for decrypting content. The DRM HAL
+ * implementation generates a key request message, delivers it to the server
+ * and receives a key response message which is then loaded into the HAL. Once
+ * the keys are loaded, the Crypto HAL decryption functionality and performance
+ * and other associated APIs can be tested by the common VTS test suite.
+ *
+ * Vendor-specific VTS modules are shared libraries used by the DRM VTS test.
+ * They provide a set of functions to support VTS testing of the DRM HAL module.
+ *
+ * The modules are placed in a common location on the file system. The VTS test
+ * scans through all vendor-provided support libraries and runs the VTS test
+ * suite on each library that is found.
+ *
+ * The vendor-specific module exposes an extern “C” vendorModuleFactory()
+ * function that returns a DrmHalVTSVendorModule instance. DrmHalVTSVendorModule
+ * instances are versioned, where each version is represented by subclass of
+ * DrmHalVTSVendorModule that corresponds to the API version. For example, a

+/**
+ * GNSS Geofence.
+ * There are 3 states associated with a Geofence: Inside, Outside, Unknown.
+ * There are 3 transitions: ENTERED, EXITED, UNCERTAIN.
+ *
+ * An example state diagram with confidence level: 95% and Unknown time limit
+ * set as 30 secs is shown below. (confidence level and Unknown time limit are
+ * explained latter).
+ * ____________________________
+ * | Unknown (30 secs) |
+ * """"""""""""""""""""""""""""
+ * ^ | | ^
+ * UNCERTAIN| |ENTERED EXITED| |UNCERTAIN
+ * | v v |
+ * ________ EXITED _________
+ * | Inside | -----------> | Outside |
+ * | | <----------- | |
+ * """""""" ENTERED """""""""
+ *
+ * Inside state: We are 95% confident that the user is inside the geofence.
+ * Outside state: We are 95% confident that the user is outside the geofence
+ * Unknown state: Rest of the time.
+ *
+ * The Unknown state is better explained with an example:
+ *
+ * __________
+ * | c|
+ * | ___ | _______
+ * | |a| | | b |
+ * | """ | """""""
+ * | |
+ * """"""""""
+ * In the diagram above, "a" and "b" are 2 geofences and "c" is the accuracy
+ * circle reported by the GNSS subsystem. Now with regard to "b", the system is
+ * confident that the user is outside. But with regard to "a" is not confident
+ * whether it is inside or outside the geofence. If the accuracy remains the
+ * same for a sufficient period of time, the UNCERTAIN transition must be
+ * triggered with the state set to Unknown. If the accuracy improves later, an
+ * appropriate transition must be triggered. This "sufficient period of time"
+ * is defined by the parameter in the addGeofenceArea API.
+ * In other words, Unknown state can be interpreted as a state in which the
+ * GNSS subsystem isn't confident enough that the user is either inside or
+ * outside the Geofence. It moves to Unknown state only after the expiry of the
+ * timeout.
+ *
+ * The geofence callback needs to be triggered for the ENTERED and EXITED
+ * transitions, when the GNSS system is confident that the user has entered
+ * (Inside state) or exited (Outside state) the Geofence. An implementation
+ * which uses a value of 95% as the confidence is recommended. The callback
+ * must be triggered only for the transitions requested by the
+ * addGeofenceArea method.
+ *
+ * Even though the diagram and explanation talks about states and transitions,
+ * the callee is only interested in the transitions. The states are mentioned
+ * here for illustrative purposes.
+ *
+ * Startup Scenario: When the device boots up, if an application adds geofences,
+ * and then we get an accurate GNSS location fix, it needs to trigger the
+ * appropriate (ENTERED or EXITED) transition for every Geofence it knows about.
+ * By default, all the Geofences will be in the Unknown state.
+ *
+ * When the GNSS system is unavailable, gnssGeofenceStatusCb must be
+ * called to inform the upper layers of the same. Similarly, when it becomes
+ * available the callback must be called. This is a global state while the
+ * UNKNOWN transition described above is per geofence.
+ *
+ * An important aspect to note is that users of this API (framework), will use
+ * other subsystems like wifi, sensors, cell to handle Unknown case and
+ * hopefully provide a definitive state transition to the third party
+ * application. GNSS Geofence will just be a signal indicating what the GNSS
+ * subsystem knows about the Geofence.

+ * Color modes that may be supported by a display.
+ *
+ * Definitions:
+ * Rendering intent generally defines the goal in mapping a source (input)
+ * color to a destination device color for a given color mode.
+ *
+ * It is important to keep in mind three cases where mapping may be applied:
+ * 1. The source gamut is much smaller than the destination (display) gamut
+ * 2. The source gamut is much larger than the destination gamut (this will
+ * ordinarily be handled using colorimetric rendering, below)
+ * 3. The source and destination gamuts are roughly equal, although not
+ * completely overlapping
+ * Also, a common requirement for mappings is that skin tones should be
+ * preserved, or at least remain natural in appearance.
+ *
+ * Colorimetric Rendering Intent (All cases):
+ * Colorimetric indicates that colors should be preserved. In the case
+ * that the source gamut lies wholly within the destination gamut or is
+ * about the same (#1, #3), this will simply mean that no manipulations
+ * (no saturation boost, for example) are applied. In the case where some
+ * source colors lie outside the destination gamut (#2, #3), those will
+ * need to be mapped to colors that are within the destination gamut,
+ * while the already in-gamut colors remain unchanged.
+ *
+ * Non-colorimetric transforms can take many forms. There are no hard
+ * rules and it's left to the implementation to define.
+ * Two common intents are described below.
+ *
+ * Stretched-Gamut Enhancement Intent (Source < Destination):
+ * When the destination gamut is much larger than the source gamut (#1), the
+ * source primaries may be redefined to reflect the full extent of the
+ * destination space, or to reflect an intermediate gamut.
+ * Skin-tone preservation would likely be applied. An example might be sRGB
+ * input displayed on a DCI-P3 capable device, with skin-tone preservation.
+ *
+ * Within-Gamut Enhancement Intent (Source >= Destination):
+ * When the device (destination) gamut is not larger than the source gamut
+ * (#2 or #3), but the appearance of a larger gamut is desired, techniques
+ * such as saturation boost may be applied to the source colors. Skin-tone
+ * preservation may be applied. There is no unique method for within-gamut
+ * enhancement; it would be defined within a flexible color mode.

+ * {r.r, r.g, r.b, 0, g.r, ...}.
+ *
+ * Given a matrix of this form and an input color [R_in, G_in, B_in], the
+ * output color [R_out, G_out, B_out] will be:
+ *
+ * R_out = R_in * r.r + G_in * g.r + B_in * b.r + Tr
+ * G_out = R_in * r.g + G_in * g.g + B_in * b.g + Tg
+ * B_out = R_in * r.b + G_in * g.b + B_in * b.b + Tb
+ *
+ * @param matrix is a 4x4 transform matrix (16 floats) as described above.
+ * @param hint is a hint value which may be used instead of the given
+ * matrix unless it is ColorTransform::ARBITRARY.
+ *
+ *
+ * SET_CLIENT_TARGET has this pseudo prototype
+ *
+ * setClientTarget(uint32_t targetSlot,
+ * int32_t targetIndex,
+ * int32_t acquireFenceIndex,
+ * Dataspace dataspace,
+ * vec<Rect> damage);
+ *
+ * Sets the buffer handle which will receive the output of client
+ * composition. Layers marked as Composition::CLIENT must be composited
+ * into this buffer prior to the call to PRESENT_DISPLAY, and layers not
+ * marked as Composition::CLIENT must be composited with this buffer by
+ * the device.
+ *
+ * The buffer handle provided may be empty if no layers are being
+ * composited by the client. This must not result in an error (unless an
+ * invalid display handle is also provided).
+ *
+ * Also provides a file descriptor referring to an acquire sync fence
+ * object, which must be signaled when it is safe to read from the client
+ * target buffer. If it is already safe to read from this buffer, an
+ * empty handle may be passed instead.
+ *
+ * For more about dataspaces, see SET_LAYER_DATASPACE.
+ *
+ * The damage parameter describes a surface damage region as defined in
+ * the description of SET_LAYER_SURFACE_DAMAGE.
+ *
+ * Will be called before PRESENT_DISPLAY if any of the layers are marked
+ * as Composition::CLIENT. If no layers are so marked, then it is not
+ * necessary to call this function. It is not necessary to call
+ * validateDisplay after changing the target through this function.
+ *
+ * @param targetSlot is the client target buffer slot to use.
+ * @param targetIndex is an index into inHandles for the new target
+ * buffer.
+ * @param acquireFenceIndex is an index into inHandles for a sync fence
+ * file descriptor as described above.
+ * @param dataspace is the dataspace of the buffer, as described in
+ * setLayerDataspace.
+ * @param damage is the surface damage region.
+ *
+ *
+ * SET_OUTPUT_BUFFER has this pseudo prototype
+ *
+ * setOutputBuffer(uint32_t bufferSlot,
+ * int32_t bufferIndex,
+ * int32_t releaseFenceIndex);
+ *
+ * Sets the output buffer for a virtual display. That is, the buffer to
+ * which the composition result will be written.
+ *
+ * Also provides a file descriptor referring to a release sync fence
+ * object, which must be signaled when it is safe to write to the output
+ * buffer. If it is already safe to write to the output buffer, an empty
+ * handle may be passed instead.
+ *
+ * Must be called at least once before PRESENT_DISPLAY, but does not have
+ * any interaction with layer state or display validation.
+ *
+ * @param bufferSlot is the new output buffer.
+ * @param bufferIndex is the new output buffer.
+ * @param releaseFenceIndex is a sync fence file descriptor as described
+ * above.
+ *
+ *
+ * VALIDATE_DISPLAY has this pseudo prototype
+ *
+ * validateDisplay();
+ *
+ * Instructs the device to inspect all of the layer state and determine if
+ * there are any composition type changes necessary before presenting the
+ * display. Permitted changes are described in the definition of
+ * Composition above.
+ *
+ *
+ * ACCEPT_DISPLAY_CHANGES has this pseudo prototype
+ *
+ * acceptDisplayChanges();
+ *
+ * Accepts the changes required by the device from the previous
+ * validateDisplay call (which may be queried using
+ * getChangedCompositionTypes) and revalidates the display. This function
+ * is equivalent to requesting the changed types from
+ * getChangedCompositionTypes, setting those types on the corresponding
+ * layers, and then calling validateDisplay again.
+ *
+ * After this call it must be valid to present this display. Calling this
+ * after validateDisplay returns 0 changes must succeed with NONE, but
+ * must have no other effect.
+ *
+ *
+ * PRESENT_DISPLAY has this pseudo prototype
+ *
+ * presentDisplay();
+ *
+ * Presents the current display contents on the screen (or in the case of
+ * virtual displays, into the output buffer).
+ *
+ * Prior to calling this function, the display must be successfully
+ * validated with validateDisplay. Note that setLayerBuffer and
+ * setLayerSurfaceDamage specifically do not count as layer state, so if
+ * there are no other changes to the layer state (or to the buffer's
+ * properties as described in setLayerBuffer), then it is safe to call
+ * this function without first validating the display.
+ *
+ *
+ * SET_LAYER_CURSOR_POSITION has this pseudo prototype
+ *
+ * setLayerCursorPosition(int32_t x, int32_t y);
+ *
+ * Asynchronously sets the position of a cursor layer.
+ *
+ * Prior to validateDisplay, a layer may be marked as Composition::CURSOR.
+ * If validation succeeds (i.e., the device does not request a composition
+ * change for that layer), then once a buffer has been set for the layer
+ * and it has been presented, its position may be set by this function at
+ * any time between presentDisplay and any subsequent validateDisplay
+ * calls for this display.
+ *
+ * Once validateDisplay is called, this function must not be called again
+ * until the validate/present sequence is completed.
+ *
+ * May be called from any thread so long as it is not interleaved with the
+ * validate/present sequence as described above.
+ *
+ * @param layer is the layer to which the position is set.
+ * @param x is the new x coordinate (in pixels from the left of the
+ * screen).
+ * @param y is the new y coordinate (in pixels from the top of the
+ * screen).
+ *
+ *
+ * SET_LAYER_BUFFER has this pseudo prototype
+ *
+ * setLayerBuffer(uint32_t bufferSlot,
+ * int32_t bufferIndex,
+ * int32_t acquireFenceIndex);
+ *
+ * Sets the buffer handle to be displayed for this layer. If the buffer
+ * properties set at allocation time (width, height, format, and usage)
+ * have not changed since the previous frame, it is not necessary to call
+ * validateDisplay before calling presentDisplay unless new state needs to
+ * be validated in the interim.
+ *
+ * Also provides a file descriptor referring to an acquire sync fence
+ * object, which must be signaled when it is safe to read from the given
+ * buffer. If it is already safe to read from the buffer, an empty handle
+ * may be passed instead.
+ *
+ * This function must return NONE and have no other effect if called for a
+ * layer with a composition type of Composition::SOLID_COLOR (because it
+ * has no buffer) or Composition::SIDEBAND or Composition::CLIENT (because
+ * synchronization and buffer updates for these layers are handled
+ * elsewhere).
+ *
+ * @param layer is the layer to which the buffer is set.
+ * @param bufferSlot is the buffer slot to use.
+ * @param bufferIndex is the buffer handle to set.
+ * @param acquireFenceIndex is a sync fence file descriptor as described above.
+ *
+ *
+ * SET_LAYER_SURFACE_DAMAGE has this pseudo prototype
+ *
+ * setLayerSurfaceDamage(vec<Rect> damage);
+ *
+ * Provides the region of the source buffer which has been modified since
+ * the last frame. This region does not need to be validated before
+ * calling presentDisplay.
+ *
+ * Once set through this function, the damage region remains the same
+ * until a subsequent call to this function.
+ *
+ * If damage is non-empty, then it may be assumed that any portion of the
+ * source buffer not covered by one of the rects has not been modified
+ * this frame. If damage is empty, then the whole source buffer must be
+ * treated as if it has been modified.
+ *
+ * If the layer's contents are not modified relative to the prior frame,
+ * damage must contain exactly one empty rect([0, 0, 0, 0]).
+ *
+ * The damage rects are relative to the pre-transformed buffer, and their
+ * origin is the top-left corner. They must not exceed the dimensions of
+ * the latched buffer.
+ *
+ * @param layer is the layer to which the damage region is set.
+ * @param damage is the new surface damage region.
+ *
+ *
+ * SET_LAYER_BLEND_MODE has this pseudo prototype
+ *
+ * setLayerBlendMode(BlendMode mode)
+ *
+ * Sets the blend mode of the given layer.
+ *
+ * @param mode is the new blend mode.
+ *
+ *
+ * SET_LAYER_COLOR has this pseudo prototype
+ *
+ * setLayerColor(Color color);
+ *
+ * Sets the color of the given layer. If the composition type of the layer
+ * is not Composition::SOLID_COLOR, this call must succeed and have no
+ * other effect.
+ *
+ * @param color is the new color.
+ *
+ *
+ * SET_LAYER_COMPOSITION_TYPE has this pseudo prototype
+ *
+ * setLayerCompositionType(Composition type);
+ *
+ * Sets the desired composition type of the given layer. During
+ * validateDisplay, the device may request changes to the composition
+ * types of any of the layers as described in the definition of
+ * Composition above.
+ *
+ * @param type is the new composition type.
+ *
+ *
+ * SET_LAYER_DATASPACE has this pseudo prototype
+ *
+ * setLayerDataspace(Dataspace dataspace);
+ *
+ * Sets the dataspace that the current buffer on this layer is in.
+ *
+ * The dataspace provides more information about how to interpret the
+ * buffer contents, such as the encoding standard and color transform.
+ *
+ * See the values of Dataspace for more information.
+ *
+ * @param dataspace is the new dataspace.
+ *
+ *
+ * SET_LAYER_DISPLAY_FRAME has this pseudo prototype
+ *
+ * setLayerDisplayFrame(Rect frame);
+ *
+ * Sets the display frame (the portion of the display covered by a layer)
+ * of the given layer. This frame must not exceed the display dimensions.
+ *
+ * @param frame is the new display frame.
+ *
+ *
+ * SET_LAYER_PLANE_ALPHA has this pseudo prototype
+ *
+ * setLayerPlaneAlpha(float alpha);
+ *
+ * Sets an alpha value (a floating point value in the range [0.0, 1.0])
+ * which will be applied to the whole layer. It can be conceptualized as a
+ * preprocessing step which applies the following function:
+ * if (blendMode == BlendMode::PREMULTIPLIED)
+ * out.rgb = in.rgb * planeAlpha
+ * out.a = in.a * planeAlpha
+ *
+ * If the device does not support this operation on a layer which is
+ * marked Composition::DEVICE, it must request a composition type change
+ * to Composition::CLIENT upon the next validateDisplay call.
+ *
+ * @param alpha is the plane alpha value to apply.
+ *
+ *
+ * SET_LAYER_SIDEBAND_STREAM has this pseudo prototype
+ *
+ * setLayerSidebandStream(int32_t streamIndex)
+ *
+ * Sets the sideband stream for this layer. If the composition type of the
+ * given layer is not Composition::SIDEBAND, this call must succeed and
+ * have no other effect.
+ *
+ * @param streamIndex is the new sideband stream.
+ *
+ *
+ * SET_LAYER_SOURCE_CROP has this pseudo prototype
+ *
+ * setLayerSourceCrop(FRect crop);
+ *
+ * Sets the source crop (the portion of the source buffer which will fill
+ * the display frame) of the given layer. This crop rectangle must not
+ * exceed the dimensions of the latched buffer.
+ *
+ * If the device is not capable of supporting a true float source crop
+ * (i.e., it will truncate or round the floats to integers), it must set
+ * this layer to Composition::CLIENT when crop is non-integral for the
+ * most accurate rendering.
+ *
+ * If the device cannot support float source crops, but still wants to
+ * handle the layer, it must use the following code (or similar) to
+ * convert to an integer crop:
+ * intCrop.left = (int) ceilf(crop.left);
+ * intCrop.top = (int) ceilf(crop.top);
+ * intCrop.right = (int) floorf(crop.right);
+ * intCrop.bottom = (int) floorf(crop.bottom);
+ *
+ * @param crop is the new source crop.
+ *
+ *
+ * SET_LAYER_TRANSFORM has this pseudo prototype
+ *
+ * Sets the transform (rotation/flip) of the given layer.
+ *
+ * setLayerTransform(Transform transform);
+ *
+ * @param transform is the new transform.
+ *
+ *
+ * SET_LAYER_VISIBLE_REGION has this pseudo prototype
+ *
+ * setLayerVisibleRegion(vec<Rect> visible);
+ *
+ * Specifies the portion of the layer that is visible, including portions
+ * under translucent areas of other layers. The region is in screen space,
+ * and must not exceed the dimensions of the screen.
+ *
+ * @param visible is the new visible region, in screen space.
+ *
+ *
+ * SET_LAYER_Z_ORDER has this pseudo prototype
+ *
+ * setLayerZOrder(uint32_t z);
+ *
+ * Sets the desired Z order (height) of the given layer. A layer with a
+ * greater Z value occludes a layer with a lesser Z value.
+ *
+ * @param z is the new Z order.

+/**
+ * This header contains various definitions that make working with keymaster tags safer and easier.
+ *
+ * It makes use of a fair amount of template metaprogramming. The metaprogramming serves the purpose
+ * of making it impossible to make certain classes of mistakes when operating on keymaster
+ * authorizations. For example, it's an error to create a KeyParameter with tag == Tag::PURPOSE
+ * and then to assign Algorithm::RSA to algorithm element of its union. But because the user
+ * must choose the union field, there could be a mismatch which the compiler has now way to
+ * diagnose.
+ *
+ * The machinery in this header solves these problems by describing which union field corresponds
+ * to which Tag. Central to this mechanism is the template TypedTag. It has zero size and binds a
+ * numeric Tag to a type that the compiler understands. By means of the macro DECLARE_TYPED_TAG,
+ * we declare types for each of the tags defined in hardware/interfaces/keymaster/2.0/types.hal.
+ *
+ * The macro DECLARE_TYPED_TAG(name) generates a typename TAG_name_t and a zero sized instance
+ * TAG_name. Once these typed tags have been declared we define metafunctions mapping the each tag
+ * to its value c++ type and the correct union element of KeyParameter. This is done by means of
+ * the macros MAKE_TAG_*VALUE_ACCESSOR, which generates TypedTag2ValueType, a metafunction mapping
+ * a typed tag to the corresponding c++ type, and access function, accessTagValue returning a
+ * reference to the correct element of KeyParameter.
+ * E.g.:
+ * given "KeyParameter param;" then "accessTagValue(TAG_PURPOSE, param)"
+ * yields a reference to param.f.purpose
+ * If used in an assignment the compiler can now check the compatibility of the assigned value.
+ *
+ * For convenience we also provide the constructor like function Authorization().
+ * Authorization takes a typed tag and a value and checks at compile time whether the value given
+ * is suitable for the given tag. At runtime it creates a new KeyParameter initialized with the
+ * given tag and value and returns it by value.
+ *
+ * The second convenience function, authorizationValue, allows access to the KeyParameter value in
+ * a safe way. It takes a typed tag and a KeyParameter and returns a reference to the value wrapped
+ * by NullOr. NullOr has out-of-band information about whether it is save to access the wrapped
+ * reference.
+ * E.g.:
+ * auto param = Authorization(TAG_ALGORITM, Algorithm::RSA);
+ * auto value1 = authorizationValue(TAG_PURPOSE, param);
+ * auto value2 = authorizationValue(TAG_ALGORITM, param);
+ * value1.isOk() yields false, but value2.isOk() yields true, thus value2.value() is save to access.

+## Omx Hal @ 1.0 tests ##
+---
+## Overview :
+The scope of the tests presented here is not restricted solely to testing omx hal @ 1.0 API but also test to omx core functionality and to an extent omx components as well. The current directory contains the following folders: audio, common, component, master and video. Besides common all other folders contain test fixtures for testing AV decoder, encoder components. Common constitutes files that are used across by these test applications.
+
+#### master :
+Functionality of master is to enumerate all the omx components (and the roles it supports) available in android media framework.
+
+usage: VtsHalMediaOmxV1\_0TargetMasterTest -I default
+
+#### component :
+This folder includes test fixtures that tests aspects common to all omx compatible components. For instance, port enabling/disabling, enumerating port formats, state transitions, flush, ..., stay common to all components irrespective of the service they offer. Test fixtures here are directed towards testing these (omx core). Every standard OMX compatible component is expected to pass these tests.
+
+usage: VtsHalMediaOmxV1\_0TargetComponentTest -I default -C <comp name> -R <comp role>
+
+#### audio :
+This folder includes test fixtures associated with testing audio encoder and decoder components such as simple encoding of a raw clip or decoding of an elementary stream, end of stream test, timestamp deviations test, flush test and so on. These tests are aimed towards testing the plugin that connects the component to the omx core.
+
+usage:
+
+VtsHalMediaOmxV1\_0TargetAudioDecTest -I default -C <comp name> -R audio_decoder.<comp class> -P /sdcard/media/
+
+VtsHalMediaOmxV1\_0TargetAudioEncTest -I default -C <comp name> -R audio_encoder.<comp class> -P /sdcard/media/
+
+#### video :
+This folder includes test fixtures associated with testing video encoder and decoder components such as simple encoding of a raw clip or decoding of an elementary stream, end of stream test, timestamp deviations test, flush test and so on. These tests are aimed towards testing the plugin that connects the component to the omx core.
+
+usage:
+
+VtsHalMediaOmxV1\_0TargetVideoDecTest -I default -C <comp name> -R video_decoder.<comp class> -P /sdcard/media/
+
+VtsHalMediaOmxV1\_0TargetVideoEncTest -I default -C <comp name> -R video_encoder.<comp class> -P /sdcard/media/
+
+While tesing audio/video encoder, decoder components, test fixtures require input files. These input are files are present in the folder 'res'. Before running the tests all the files in 'res' have to be placed in '/media/sdcard/' or a path of your choice and this path needs to be provided as an argument to the test application

+ * The Memory Tracker HAL is designed to return information about

+ * The primary goal is to be able to track memory that is not
+ * trackable in any other way, for example texture memory that is allocated by
+ * a process, but not mapped in to that process's address space.
+ * A secondary goal is to be able to categorize memory used by a process into
+ * GL, graphics, etc. All memory sizes must be in real memory usage,
+ * accounting for stride, bit depth, rounding up to page size, etc.
+ *
+ * Constructor for the interface should be used to perform memtrack management
+ * setup actions and is called once before any calls to getMemory().
+ */

+ * getMemory() populates MemtrackRecord vector with the sizes of memory
+ * plus associated flags for that memory.
+ *
+ * This function must be thread-safe, it may get called from multiple
+ * threads at the same time.
+ *
+ * A process collecting memory statistics will call getMemory for each
+ * combination of pid and memory type. For each memory type that it
+ * recognizes, the HAL must fill out an array of memtrack_record
+ * structures breaking down the statistics of that memory type as much as
+ * possible. For example,
+ * getMemory(<pid>, GL) might return:
+ * { { 4096, ACCOUNTED | PRIVATE | SYSTEM },
+ * { 40960, UNACCOUNTED | PRIVATE | SYSTEM },
+ * { 8192, ACCOUNTED | PRIVATE | DEDICATED },
+ * { 8192, UNACCOUNTED | PRIVATE | DEDICATED } }
+ * If the HAL cannot differentiate between SYSTEM and DEDICATED memory, it
+ * could return:
+ * { { 12288, ACCOUNTED | PRIVATE },
+ * { 49152, UNACCOUNTED | PRIVATE } }
+ *
+ * Memory must not overlap between types. For example, a graphics buffer
+ * that has been mapped into the GPU as a surface must show up when
+ * GRAPHICS is requested and not when GL
+ * is requested.
+ *
+ * @param pid process for which memory information is requested
+ * @param type memory type that information is being requested about
+ * @return records vector of MemtrackRecord containing memory information
+ * @return retval SUCCESS on success, TYPE_NOT_FOUND if the type is not
+ * supported.

+ * Sensor type
+ *
+ * Each sensor has a type which defines what this sensor measures and how
+ * measures are reported. See the Base sensors and Composite sensors lists
+ * for complete descriptions:
+ * http://source.android.com/devices/sensors/base_triggers.html
+ * http://source.android.com/devices/sensors/composite_sensors.html
+ *
+ * Device manufacturers (OEMs) can define their own sensor types, for
+ * their private use by applications or services provided by them. Such
+ * sensor types are specific to an OEM and can't be exposed in the SDK.
+ * These types must start at SensorType::DEVICE_PRIVATE_BASE.
+ *
+ * All sensors defined outside of the device private range must correspond to
+ * a type defined in this file, and must satisfy the characteristics listed in
+ * the description of the sensor type.
+ *
+ * Each sensor also has a "typeAsString".
+ * - string type of sensors defined in this file is overridden by Android to
+ * values defined in Android API with "android.sensor." prefix.
+ * Example: for an accelerometer,
+ * type = SensorType::Acclerometer
+ * typeAsString = "" (will be replace by "android.sensor.accelerometer" by
+ * Android frameowrk)
+ * - string type of sensors inside of the device private range MUST be prefixed
+ * by the sensor provider's or OEM reverse domain name. In particular, they
+ * cannot use the "android.sensor." prefix.
+ *
+ * When android introduces a new sensor type that can replace an OEM-defined
+ * sensor type, the OEM must use the official sensor type and stringType on
+ * versions of the HAL that support this new official sensor type.
+ *
+ * Example (made up): Suppose Google's Glass team wants to surface a sensor
+ * detecting that Glass is on a head.
+ * - Such a sensor is not officially supported in android KitKat
+ * - Glass devices launching on KitKat can implement a sensor with
+ * type = 0x10001
+ * typeAsString = "com.google.glass.onheaddetector"
+ * - In L android release, if android decides to define
+ * SensorType::ON_HEAD_DETECTOR and STRING_SensorType::ON_HEAD_DETECTOR,
+ * those types should replace the Glass-team-specific types in all future
+ * launches.
+ * - When launching Glass on the L release, Google should now use the official
+ * type (SensorType::ON_HEAD_DETECTOR) and stringType.
+ * - This way, all applications can now use this sensor.

+/**
+ * Wake up sensors.
+ * Each sensor may have either or both a wake-up and a non-wake variant.
+ * When registered in batch mode, wake-up sensors will wake up the AP when
+ * their FIFOs are full or when the batch timeout expires. A separate FIFO has
+ * to be maintained for wake up sensors and non wake up sensors. The non
+ * wake-up sensors need to overwrite their FIFOs when they are full till the AP
+ * wakes up and the wake-up sensors will wake-up the AP when their FIFOs are
+ * full or when the batch timeout expires without losing events.
+ * Wake-up and non wake-up variants of each sensor can be activated at
+ * different rates independently of each other.
+ *
+ * Note: Proximity sensor and significant motion sensor which were defined in
+ * previous releases are also wake-up sensors and must be treated as such.
+ * Wake-up one-shot sensors like SIGNIFICANT_MOTION cannot be batched, hence
+ * the text about batch above doesn't apply to them. See the definitions of
+ * SensorType::PROXIMITY and SensorType::SIGNIFICANT_MOTION for more info.
+ *
+ * Set SENSOR_FLAG_WAKE_UP flag for all wake-up sensors.
+ *
+ * For example, A device can have two sensors both of SensorType::ACCELEROMETER
+ * and one of them can be a wake_up sensor (with SENSOR_FLAG_WAKE_UP flag set)
