* <p>The device supports constrained high speed video recording (frame rate >=120fps)
* use case. The camera device will support high speed capture session created by
* {@link android.hardware.camera2.CameraDevice#createConstrainedHighSpeedCaptureSession }, which
* only accepts high speed request lists created by
* {@link android.hardware.camera2.CameraConstrainedHighSpeedCaptureSession#createHighSpeedRequestList }.</p>
* <p>A camera device can still support high speed video streaming by advertising the high speed
* FPS ranges in {@link CameraCharacteristics#CONTROL_AE_AVAILABLE_TARGET_FPS_RANGES android.control.aeAvailableTargetFpsRanges}. For this case, all normal
* capture request per frame control and synchronization requirements will apply to
* the high speed fps ranges, the same as all other fps ranges. This capability describes
* the capability of a specialized operating mode with many limitations (see below), which
* is only targeted at high speed video recording.</p>
* <p>The supported high speed video sizes and fps ranges are specified in
* {@link android.hardware.camera2.params.StreamConfigurationMap#getHighSpeedVideoFpsRanges }.
* To get desired output frame rates, the application is only allowed to select video size
* and FPS range combinations provided by
* {@link android.hardware.camera2.params.StreamConfigurationMap#getHighSpeedVideoSizes }.
* The fps range can be controlled via {@link CaptureRequest#CONTROL_AE_TARGET_FPS_RANGE android.control.aeTargetFpsRange}.</p>
* <p>In this capability, the camera device will override aeMode, awbMode, and afMode to
* ON, AUTO, and CONTINUOUS_VIDEO, respectively. All post-processing block mode
* controls will be overridden to be FAST. Therefore, no manual control of capture
* and post-processing parameters is possible. All other controls operate the
* same as when {@link CaptureRequest#CONTROL_MODE android.control.mode} == AUTO. This means that all other
* android.control.* fields continue to work, such as</p>
* <ul>
* <li>{@link CaptureRequest#CONTROL_AE_TARGET_FPS_RANGE android.control.aeTargetFpsRange}</li>
* <li>{@link CaptureRequest#CONTROL_AE_EXPOSURE_COMPENSATION android.control.aeExposureCompensation}</li>
* <li>{@link CaptureRequest#CONTROL_AE_LOCK android.control.aeLock}</li>
* <li>{@link CaptureRequest#CONTROL_AWB_LOCK android.control.awbLock}</li>

* <li>{@link CaptureRequest#CONTROL_AF_TRIGGER android.control.afTrigger}</li>
* <li>{@link CaptureRequest#CONTROL_AE_PRECAPTURE_TRIGGER android.control.aePrecaptureTrigger}</li>
* </ul>
* <p>Outside of android.control.*, the following controls will work:</p>
* <ul>
* <li>{@link CaptureRequest#FLASH_MODE android.flash.mode} (TORCH mode only, automatic flash for still capture will not
* work since aeMode is ON)</li>
* <li>{@link CaptureRequest#LENS_OPTICAL_STABILIZATION_MODE android.lens.opticalStabilizationMode} (if it is supported)</li>
* <li>{@link CaptureRequest#SCALER_CROP_REGION android.scaler.cropRegion}</li>
* <li>{@link CaptureRequest#STATISTICS_FACE_DETECT_MODE android.statistics.faceDetectMode} (if it is supported)</li>
* </ul>
* <p>For high speed recording use case, the actual maximum supported frame rate may
* be lower than what camera can output, depending on the destination Surfaces for
* the image data. For example, if the destination surface is from video encoder,
* the application need check if the video encoder is capable of supporting the
* high frame rate for a given video size, or it will end up with lower recording
* frame rate. If the destination surface is from preview window, the actual preview frame
* rate will be bounded by the screen refresh rate.</p>
* <p>The camera device will only support up to 2 high speed simultaneous output surfaces
* (preview and recording surfaces)
* in this mode. Above controls will be effective only if all of below conditions are true:</p>
* <ul>
* <li>The application creates a camera capture session with no more than 2 surfaces via
* {@link android.hardware.camera2.CameraDevice#createConstrainedHighSpeedCaptureSession }. The
* targeted surfaces must be preview surface (either from
* {@link android.view.SurfaceView } or {@link android.graphics.SurfaceTexture }) or
* recording surface(either from {@link android.media.MediaRecorder#getSurface } or
* {@link android.media.MediaCodec#createInputSurface }).</li>
* <li>The stream sizes are selected from the sizes reported by
* {@link android.hardware.camera2.params.StreamConfigurationMap#getHighSpeedVideoSizes }.</li>
* <li>The FPS ranges are selected from
* {@link android.hardware.camera2.params.StreamConfigurationMap#getHighSpeedVideoFpsRanges }.</li>
* </ul>
* <p>When above conditions are NOT satistied,
* {@link android.hardware.camera2.CameraDevice#createConstrainedHighSpeedCaptureSession }
* will fail.</p>
* <p>Switching to a FPS range that has different maximum FPS may trigger some camera device
* reconfigurations, which may introduce extra latency. It is recommended that
* the application avoids unnecessary maximum target FPS changes as much as possible
* during high speed streaming.</p>

* <p>Therefore, HDR captures operate at a much slower rate
* than regular captures.</p>
* <p>In this mode, on LIMITED or FULL devices, when a request
* is made with a {@link CaptureRequest#CONTROL_CAPTURE_INTENT android.control.captureIntent} of

* may involve the device using specialized high dynamic
* range capture hardware. In all cases, a single image is
