Class AVCapturePrimaryConstituentDeviceRestrictedSwitchingBehaviorConditions

  • public final class AVCapturePrimaryConstituentDeviceRestrictedSwitchingBehaviorConditions
extends java.lang.Object
    [@enum] AVCapturePrimaryConstituentDeviceRestrictedSwitchingBehaviorConditions These constants can be used and combined to control the conditions that allow fallback camera selection when the primaryConstituentDeviceSelectionBehavior is set to AVCapturePrimaryConstituentDeviceSwitchingBehaviorRestricted. Note that camera switching necessary to satisfy the requested zoom factor is still allowed. [@constant] AVCapturePrimaryConstituentDeviceRestrictedSwitchingBehaviorConditionNone Disallow fallback switching. [@constant] AVCapturePrimaryConstituentDeviceRestrictedSwitchingBehaviorConditionVideoZoomChanged Restrict fallback camera switching to when the video zoom factor changes, either through AVCaptureDevice.videoZoomFactor or -[AVCaptureDevice rampToVideoZoomFactor:withRate:]. Note that any change in video zoom factor will allow a switch to a fallback camera, not just changes across switch-over zoom factors. [@constant] AVCapturePrimaryConstituentDeviceRestrictedSwitchingBehaviorConditionFocusModeChanged Restrict fallback camera switches to when AVCaptureDevice.focusMode is set. [@constant] AVCapturePrimaryConstituentDeviceRestrictedSwitchingBehaviorConditionExposureModeChanged Restrict fallback camera switches to when AVCaptureDevice.exposureMode is set. Whenever triggered by one or more of the enabled conditions, the fallback camera switching waits for exposure and focus to stabilize before deciding which camera to use as the primary constituent device. Whenever AVCapturePrimaryConstituentDeviceRestrictedSwitchingBehaviorConditionVideoZoomChanged is not included in the restricted switching behavior conditions, AVCapturePrimaryConstituentDeviceSwitchingBehaviorRestricted still allows camera selection when a change in video zoom factor makes a camera eligible or ineligible to be selected as the activePrimaryConstituentDevice. When the video zoom factor decreases to below the switch-over zoom factor of the activePrimaryConstituentDevice, a different camera will be selected to satisfy the requested zoom factor. When the video zoom factor increases and crosses a camera's switch-over zoom factor, this camera becomes eligible to be selected as the activePrimaryConstituentDevice. If exposure and focus allow, this camera then becomes the new activePrimaryConstituentDevice. Similar to the AVCapturePrimaryConstituentDeviceRestrictedSwitchingBehaviorConditionVideoZoomChanged this also waits for exposure and focus to stabilize. Otherwise the activePrimaryConstituentDevice remains unchanged. API-Since: 15.0
