/**
* <p>Returns a subset of {@link #getAvailableCaptureRequestKeys} keys that the
* camera device can pass as part of the capture session initialization.</p>
*
* <p>This list includes keys that are difficult to apply per-frame and
* can result in unexpected delays when modified during the capture session
* lifetime. Typical examples include parameters that require a
* time-consuming hardware re-configuration or internal camera pipeline
* change. For performance reasons we suggest clients to pass their initial
* values as part of {@link SessionConfiguration#setSessionParameters}. Once
* the camera capture session is enabled it is also recommended to avoid
* changing them from their initial values set in
* {@link SessionConfiguration#setSessionParameters }.
* Control over session parameters can still be exerted in capture requests
* but clients should be aware and expect delays during their application.
* An example usage scenario could look like this:</p>
* <ul>
* <li>The camera client starts by querying the session parameter key list via
* {@link android.hardware.camera2.CameraCharacteristics#getAvailableSessionKeys }.</li>
* <li>Before triggering the capture session create sequence, a capture request
* must be built via {@link CameraDevice#createCaptureRequest } using an
* appropriate template matching the particular use case.</li>
* <li>The client should go over the list of session parameters and check
* whether some of the keys listed matches with the parameters that
* they intend to modify as part of the first capture request.</li>
* <li>If there is no such match, the capture request can be passed
* unmodified to {@link SessionConfiguration#setSessionParameters }.</li>
* <li>If matches do exist, the client should update the respective values
* and pass the request to {@link SessionConfiguration#setSessionParameters }.</li>
* <li>After the capture session initialization completes the session parameter
* key list can continue to serve as reference when posting or updating
* further requests. As mentioned above further changes to session
* parameters should ideally be avoided, if updates are necessary
* however clients could expect a delay/glitch during the
* parameter switch.</li>
* </ul>
*
* <p>The list returned is not modifiable, so any attempts to modify it will throw
* a {@code UnsupportedOperationException}.</p>
*
* <p>Each key is only listed once in the list. The order of the keys is undefined.</p>

* <p>For the high speed video use case, the application must

* to do high speed recording, it can select the maximum size reported by this metadata to

* 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_max / 30. For example,
* if max_fps is 300, max batch size will only be 1, 2, 5, or 10.</li>
* <li>The camera device may choose smaller internal batch size for each configuration, but
* the actual batch size will be a divisor of max batch size. For example, if the max batch
* size is 8, the actual batch size used by camera device will only be 1, 2, 4, or 8.</li>
* <li>The max batch size in each configuration entry must be no larger than 32.</li>
* </ul>
* <p>The camera device doesn't have to support batch mode to achieve high speed video recording,
* in such case, batch_size_max will be reported as 1 in each configuration entry.</p>
* <p>This fps ranges in this configuration list can only be used to create requests
* that are submitted to a high speed camera capture session created by

* <ul>
* <li>The camera client starts by querying the session parameter key list via

* <li>Before triggering the capture session create sequence, a capture request

* <li>If matches do exist, the client should update the respective values
* and pass the request to
* {@link SessionConfiguration#setSessionParameters }.</li>
* <li>After the capture session initialization completes the session parameter
* key list can continue to serve as reference when posting or updating

/**
* <p>This lists the maximum stall duration for each
* output format/size combination.</p>
* <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.</p>
* <p>For example, 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, they act as JPEG streams. This is because supporting a
* JPEG stream requires the underlying YUV data to always be ready for
* use by a JPEG encoder, but the encoder will only be used (and impact
* frame duration) on requests that actually reference a JPEG stream.</li>
* <li>The JPEG processor can run concurrently to the rest of the camera
* pipeline, but cannot process more than 1 capture at a time.</li>
* </ul>
* <p>In other words, using a repeating YUV request would result
* in a steady frame rate (let's say it's 30 FPS). If a single
* JPEG request is submitted periodically, the frame rate will stay
* at 30 FPS (as long as we wait for the previous JPEG to return each
* time). If we try to submit a repeating YUV + JPEG request, then
* the frame rate will drop from 30 FPS.</p>
* <p>In general, 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.</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>, added with
* the maximum stall duration for <code>S</code>.</p>
* <p>If interleaving requests with and without a stall duration,
* a request will stall by the maximum of the remaining times
* for each can-stall stream with outstanding buffers.</p>
* <p>This means that a stalling request will not have an exposure start
* until the stall has completed.</p>
* <p>This should correspond to the stall duration when only that stream is
* active, with all processing (typically in android.*.mode) set to FAST
* or OFF. Setting any of the processing modes to HIGH_QUALITY
* effectively results in an indeterminate stall duration for all
* streams in a request (the regular stall calculation rules are
* ignored).</p>
* <p>The following formats may always have a stall duration:</p>
* <ul>
* <li>{@link android.graphics.ImageFormat#JPEG }</li>
* <li>{@link android.graphics.ImageFormat#RAW_SENSOR }</li>
* </ul>
* <p>The following formats will never have a stall duration:</p>
* <ul>
* <li>{@link android.graphics.ImageFormat#YUV_420_888 }</li>
* <li>{@link android.graphics.ImageFormat#RAW10 }</li>
* <li>{@link android.graphics.ImageFormat#RAW12 }</li>
* <li>{@link android.graphics.ImageFormat#Y8 }</li>
* </ul>
* <p>All other formats may or may not have an allowed stall duration on
* a per-capability basis; refer to {@link CameraCharacteristics#REQUEST_AVAILABLE_CAPABILITIES android.request.availableCapabilities}

* <p>This is the rectangle representing the size of the active region of the sensor (i.e.
* the region that actually receives light from the scene) after any geometric correction
* has been applied, and should be treated as the maximum size in pixels of any of the
* image output formats aside from the raw formats.</p>
* <p>This rectangle is defined relative to the full pixel array; (0,0) is the top-left of
* the full pixel array, and the size of the full pixel array is given by
* {@link CameraCharacteristics#SENSOR_INFO_PIXEL_ARRAY_SIZE android.sensor.info.pixelArraySize}.</p>
* <p>The coordinate system for most other keys that list pixel coordinates, including
* {@link CaptureRequest#SCALER_CROP_REGION android.scaler.cropRegion}, is defined relative to the active array rectangle given in

* <p>The active array may be smaller than the full pixel array, since the full array may
* include black calibration pixels or other inactive regions.</p>
* <p>For devices that do not support {@link CaptureRequest#DISTORTION_CORRECTION_MODE android.distortionCorrection.mode} control, the active

* pre-correction active array and active array accounts for scaling or cropping caused
* by lens geometric distortion correction.</p>
* <p>In general, application should always refer to active array size for controls like
* metering regions or crop region. Two exceptions are when the application is dealing with

* <p>The size of this region determines the maximum field of view and the maximum number of

* <p>E.g. to calculate position of a pixel, (x,y), in a processed YUV output image with the

* <ol>
* <li>Choose a pixel (x', y') within the active array region of the raw buffer given in
* {@link CameraCharacteristics#SENSOR_INFO_PRE_CORRECTION_ACTIVE_ARRAY_SIZE android.sensor.info.preCorrectionActiveArraySize}, otherwise this pixel is considered
* to be outside of the FOV, and will not be shown in the processed output image.</li>
* <li>Apply geometric distortion correction to get the post-distortion pixel coordinate,
* (x_i, y_i). When applying geometric correction metadata, note that metadata for raw
* buffers is defined relative to the top, left of the
* {@link CameraCharacteristics#SENSOR_INFO_PRE_CORRECTION_ACTIVE_ARRAY_SIZE android.sensor.info.preCorrectionActiveArraySize} rectangle.</li>
* <li>If the resulting corrected pixel coordinate is within the region given in

* with dimensions given in {@link CameraCharacteristics#SENSOR_INFO_PIXEL_ARRAY_SIZE android.sensor.info.pixelArraySize}, and would be (5, 5)

* <li><code>LEGACY</code> devices operate in a backwards-compatibility mode for older
* Android devices, and have very limited capabilities.</li>
* <li><code>LIMITED</code> devices represent the
* baseline feature set, and may also include additional capabilities that are
* subsets of <code>FULL</code>.</li>
* <li><code>FULL</code> devices additionally support per-frame manual control of sensor, flash, lens and
* post-processing settings, and image capture at a high rate.</li>
* <li><code>LEVEL_3</code> devices additionally support YUV reprocessing and RAW image capture, along
* with additional output stream configurations.</li>
* <li><code>EXTERNAL</code> devices are similar to <code>LIMITED</code> devices with exceptions like some sensor or
* lens information not reported or less stable framerates.</li>
* </ul>
* <p>See the individual level enums for full descriptions of the supported capabilities. The
