+ * S10. Reprocessing flow and controls
+ *
+ * This section describes the OPAQUE and YUV reprocessing flow and controls. OPAQUE reprocessing
+ * uses an opaque format that is not directly application-visible, and the application can
+ * only select some of the output buffers and send back to HAL for reprocessing, while YUV
+ * reprocessing gives the application opportunity to process the buffers before reprocessing.
+ *
+ * S8 gives the stream configurations for the typical reprocessing uses cases,
+ * this section specifies the buffer flow and controls in more details.
+ *
+ * S10.1 OPAQUE (typically for ZSL use case) reprocessing flow and controls
+ *
+ * For OPAQUE reprocessing (e.g. ZSL) use case, after the application creates the specific
+ * output and input streams, runtime buffer flow and controls are specified as below:
+ *
+ * 1. Application starts output streaming by sending repeating requests for output
+ * opaque buffers and preview. The buffers are held by an application
+ * maintained circular buffer. The requests are based on CAMERA3_TEMPLATE_ZERO_SHUTTER_LAG
+ * capture template, which should have all necessary settings that guarantee output
+ * frame rate is not slowed down relative to sensor output frame rate.
+ *
+ * 2. When a capture is issued, the application selects one output buffer based
+ * on application buffer selection logic, e.g. good AE and AF statistics etc.
+ * Application then creates an reprocess request based on the capture result associated
+ * with this selected buffer. The selected output buffer is now added to this reprocess
+ * request as an input buffer, the output buffer of this reprocess request should be
+ * either JPEG output buffer or YUV output buffer, or both, depending on the application
+ * choice.
+ *
+ * 3. Application then alters the reprocess settings to get best image quality. The HAL must
+ * support and only support below controls if the HAL support OPAQUE_REPROCESSING capability:
+ * - android.jpeg.* (if JPEG buffer is included as one of the output)
+ * - android.noiseReduction.mode (change to HIGH_QUALITY if it is supported)
+ * - android.edge.mode (change to HIGH_QUALITY if it is supported)
+ * All other controls must be ignored by the HAL.
+ * 4. HAL processed the input buffer and return the output buffers in the capture results
+ * as normal.
+ *
+ * S10.2 YUV reprocessing flow and controls
+ *
+ * The YUV reprocessing buffer flow is similar as OPAQUE reprocessing, with below difference:
+ *
+ * 1. Application may want to have finer granularity control of the intermediate YUV images
+ * (before reprocessing). For example, application may choose
+ * - android.noiseReduction.mode == MINIMAL
+ * to make sure the no YUV domain noise reduction has applied to the output YUV buffers,
+ * then it can do its own advanced noise reduction on them. For OPAQUE reprocessing case, this
+ * doesn't matter, as long as the final reprocessed image has the best quality.
+ * 2. Application may modify the YUV output buffer data. For example, for image fusion use
+ * case, where multiple output images are merged together to improve the signal-to-noise
+ * ratio (SNR). The input buffer may be generated from multiple buffers by the application.
+ * To avoid excessive amount of noise reduction and insufficient amount of edge enhancement
+ * being applied to the input buffer, the application can hint the HAL how much effective
+ * exposure time improvement has been done by the application, then the HAL can adjust the
+ * noise reduction and edge enhancement paramters to get best reprocessed image quality.
+ * Below tag can be used for this purpose:
+ * - android.reprocess.effectiveExposureFactor
+ * The value would be exposure time increase factor applied to the original output image,
+ * for example, if there are N image merged, the exposure time increase factor would be up
+ * to sqrt(N). See this tag spec for more details.
+ *
+ * S10.3 Reprocessing pipeline characteristics
+ *
+ * Reprocessing pipeline has below different characteristics comparing with normal output
+ * pipeline:
+ *
+ * 1. The reprocessing result can be returned ahead of the pending normal output results. But
+ * the FIFO ordering must be maintained for all reprocessing results. For example, there are
+ * below requests (A stands for output requests, B stands for reprocessing requests)
+ * being processed by the HAL:
+ * A1, A2, A3, A4, B1, A5, B2, A6...
+ * result of B1 can be returned before A1-A4, but result of B2 must be returned after B1.
+ * 2. Single input rule: For a given reprocessing request, all output buffers must be from the
+ * input buffer, rather than sensor output. For example, if a reprocess request include both
+ * JPEG and preview buffers, all output buffers must be produced from the input buffer
+ * included by the reprocessing request, rather than sensor. The HAL must not output preview
+ * buffers from sensor, while output JPEG buffer from the input buffer.
+ * 3. Input buffer will be from camera output directly (ZSL case) or indirectly(image fusion
+ * case). For the case where buffer is modified, the size will remain same. The HAL can
+ * notify CAMERA3_MSG_ERROR_REQUEST if buffer from unknown source is sent.
+ * 4. Result as reprocessing request: The HAL can expect that a reprocessing request is a copy
+ * of one of the output results with minor allowed setting changes. The HAL can notify
+ * CAMERA3_MSG_ERROR_REQUEST if a request from unknown source is issued.
+ * 5. Output buffers may not be used as inputs across the configure stream boundary, This is
+ * because an opaque stream like the ZSL output stream may have different actual image size
+ * inside of the ZSL buffer to save power and bandwidth for smaller resolution JPEG capture.
+ * The HAL may notify CAMERA3_MSG_ERROR_REQUEST if this case occurs.
+ * 6. HAL Reprocess requests error reporting during flush should follow the same rule specified
+ * by flush() method.

+ * open() is called to open a camera device, the camera HAL module must notify the
+ * framework through the torch mode status callback that the torch mode has been
+ * turned off.
+ *
+ * 2. External camera (e.g. USB hot-plug camera) support. The API updates specify that
+ * the camera static info is only available when camera is connected and ready to
+ * use for external hot-plug cameras. Calls to get static info will be invalid
+ * calls when camera status is not CAMERA_DEVICE_STATUS_PRESENT. The frameworks
+ * will only count on device status change callbacks to manage the available external
+ * camera list.
+ *
+ * 3. Camera arbitration hints. This module version adds support for explicitly
+ * indicating the number of camera devices that can be simultaneously opened and used.
+ * To specify valid combinations of devices, the resource_cost and conflicting_devices
+ * fields should always be set in the camera_info structure returned by the

+ *
+ * The camera service must be able to simultaneously open and use any

+ * The camera service may still attempt to simultaneously open combinations

+ *
+ * This field will 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 will 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.

+ * Camera Device 0 - resource_cost = 51
+ * conflicting_devices = null
+ * Camera Device 1 - resource_cost = 51

+ * Result:

+ * Since the sum of the resource costs is > 100, if a higher-priority

+ * application is using a device that a higher-priority subsequently attempts
+ * to open, the lower-priority application will 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 - resource_cost = 50
+ * conflicting_devices = { 2 }
+ * Camera Device 1 - resource_cost = 50
+ * conflicting_devices = { 2 }
+ * Camera Device 2 - resource_cost = 100
+ * conflicting_devices = { 0, 1 }
+ * Camera Device 3 - resource_cost = 50
+ * conflicting_devices = null
+ *
+ * Result:
+ *
+ * Based on the conflicting_devices fields, the camera service guarantees that
+ * the following sets of open devices will never be allowed: { 1, 2 }, { 0, 2 }.
+ *
+ * Based on the resource_cost fields, if a high-priority foreground application
+ * is using camera device 0, a background application would be allowed to open
+ * camera device 1 or 3 (but would be forced to disconnect it again if the
+ * foreground application opened another device).
+ *
+ * The highest priority application may still attempt to simultaneously open

+ *
+ * Ex. 3: Camera Device 0 = Back Camera
+ * Camera Device 1 = Front Camera
+ * Camera Device 2 = Low-power Front Camera that uses the same
