Detailed Description

The QCamera class provides an interface for system camera devices. QCamera can be used with QCameraViewfinder for viewfinder display, QMediaRecorder for video recording, and QCameraImageCapture for image taking.

You can use QCameraInfo to list available cameras and choose which one to use.

QList<QCameraInfo> cameras = QCameraInfo::availableCameras();
 
for (const QCameraInfo &cameraInfo : cameras) {
   if (cameraInfo.deviceName() == "mycamera") {
      camera = new QCamera(cameraInfo);
   }
}

QCamera::CaptureViewfinder	0	Camera is only configured to display viewfinder.
QCamera::CaptureStillImage	0x01	Camera is configured for still frames capture.
QCamera::CaptureVideo	0x02	Camera is configured for video capture.

enum QCamera::Error

Error codes.

Constant	Value	Description
QCamera::NoError	0	No errors have occurred.
QCamera::CameraError	1	An error has occurred.
QCamera::InvalidRequestError	2	System resource does not support requested functionality.
QCamera::ServiceMissingError	3	No camera service available.
QCamera::NotSupportedFeatureError	4	Feature is not supported.

enum QCamera::LockChangeReason

Enum containing reasons a lock status has changed.

Constant	Value	Description
QCamera::UserRequest	0	Lock status changed in result of user request, usually to unlock camera settings.
QCamera::LockAcquired	1	Lock status successfully changed to QCamera::Locked.
QCamera::LockFailed	2	Camera failed to acquire the requested lock in result of autofocus failure, exposure out of supported range, etc.
QCamera::LockLost	3	Camera is not able to maintain the requested lock any more. Lock status is changed to QCamera::Unlocked.
QCamera::LockTemporaryLost	4	Lock is lost but the camera is working to reacquire it. This value may be used in continuous focusing mode, when the camera loses the focus, the focus lock state is changed to QCamera::Searching with LockTemporaryLost reason.

enum QCamera::LockStatus

Enum contains values indicating the status of the camera setting.

Constant	Value	Description
QCamera::Unlocked	0	Application is not interested in camera settings value.
QCamera::Searching	1	Application has requested the camera focus, exposure, or white balance lock with QCamera::searchAndLock(). This state indicates the camera is focusing or calculating exposure and white balance.
QCamera::Locked	2	Camera focus, exposure, or white balance is locked. The camera is ready to capture.

enum QCamera::LockType

Used to specify a camera setting indicating how the camera should focus.

Constant	Value	Description
QCamera::NoLock	0
QCamera::LockExposure	0x01	Lock camera exposure.
QCamera::LockWhiteBalance	0x02	Lock the white balance.
QCamera::LockFocus	0x04	Lock camera focus.

enum QCamera::Position

This enum specifies the physical position of the camera on the system.

Constant	Value	Description
QCamera::UnspecifiedPosition	0	Camera position is unspecified or unknown.
QCamera::BackFace	1	Camera is on the back face of the system hardware. For example on a mobile device, it means it is on the opposite side to that of the screen.
QCamera::FrontFace	2	Camera is on the front face of the system hardware. For example on a mobile device, it means it is on the same side as that of the screen. Viewfinder frames of front-facing cameras are mirrored horizontally, so the users can see themselves as looking into a mirror. Captured images or videos are not mirrored.

See also: QCameraInfo::position()

enum QCamera::State

Specifies the current state of the camera.

Constant	Value	Description
Camera::UnloadedState	0	Initial state with the camera not loaded. While the supported settings are unknown in this state, you can set the camera capture settings like codec, resolution, or frame rate.
QCamera::LoadedState	1	Camera is loaded and ready to be configured.
QCamera::ActiveState	2	When the camera is started the viewfinder displays video frames and the camera is ready for capture.

enum QCamera::Status

Enum contains camera status information.

Depending on which backend is used, changing some of the camera settings like capture mode, codecs, or resolution in the ActiveState may change the camera status.

Constant	Value	Description
QCamera::ActiveStatus	8	Camera has been started and can produce data. The viewfinder displays video frames in active state.
QCamera::StartingStatus	6	Camera is starting in result of state transition to QCamera::ActiveState. The camera service is not ready to capture yet.

Constructor & Destructor Documentation

QCamera::QCamera ( QObject * parent = nullptr )

explicit

Construct a QCamera with a parent.

QCamera::QCamera	(	const QByteArray &	deviceName,
		QObject *	parent = `nullptr`
	)

explicit

Construct a QCamera from deviceName and parent. If no camera with that deviceName exists, the camera object will be invalid.

QCamera::QCamera	(	const QCameraInfo &	cameraInfo,
		QObject *	parent = `nullptr`
	)

explicit

Construct a QCamera from a camera description cameraInfo and parent.

QCamera::QCamera	(	QCamera::Position	position,
		QObject *	parent = `nullptr`
	)

explicit

Construct a QCamera which uses a hardware camera located at the specified position. For example on a mobile phone it can be used to easily choose between front-facing and back-facing cameras.

If no camera is available at the specified position or if position is QCamera::UnspecifiedPosition, the default camera is used.

QCamera::~QCamera ( )

Destroys the camera object.

Method Documentation

QMultimedia::AvailabilityStatus QCamera::availability ( ) const

overridevirtual

Returns the availability state of the camera service.

Reimplemented from QMediaObject::availability()

CaptureModes QCamera::captureMode ( ) const

Returns the value of the property.

void QCamera::captureModeChanged ( QCamera::CaptureModes mode )

signal

Signals the capture mode has changed.

Error QCamera::error ( ) const

Returns the error state of the object.

void QCamera::error ( QCamera::Error error )

signal

Signal emitted when error state changes to error.

QString QCamera::errorString ( ) const

Returns a string describing a camera's error state.

QCameraExposure * QCamera::exposure ( ) const

Returns the camera exposure control object.

QCameraFocus * QCamera::focus ( ) const

Returns the camera focus control object.

QCameraImageProcessing * QCamera::imageProcessing ( ) const

Returns the camera image processing control object.

bool QCamera::isCaptureModeSupported ( CaptureModes mode ) const

Returns true if the capture mode is supported.

void QCamera::load ( )

slot

Opens the camera device. The camera status is changed to QCamera::LoadedStatus.

It is not necessary to explicitly call this method unless the application needs to read the supported camera settings and change the defaults. If the default settings are acceptable start the camera directly from the unloaded state.

void QCamera::locked ( )

signal

Signals all the requested camera settings are locked.

void QCamera::lockFailed ( )

signal

Signals locking of at least one requested camera settings failed.

QCamera::LockStatus QCamera::lockStatus ( ) const

inline

Returns the status of requested camera settings locks.

QCamera::LockStatus QCamera::lockStatus ( QCamera::LockType lockType ) const

Returns the lock status for a given lockType.

void QCamera::lockStatusChanged	(	QCamera::LockStatus	status,
		QCamera::LockChangeReason	reason
	)

signal

Signals the overall status for all the requested camera locks was changed with specified reason.

void QCamera::lockStatusChanged	(	QCamera::LockType	type,
		QCamera::LockStatus	status,
		QCamera::LockChangeReason	reason
	)

signal

Signals the type and status was changed with specified reason.

QCamera::LockTypes QCamera::requestedLocks ( ) const

Returns the requested lock types.

void QCamera::searchAndLock ( )

slot

Lock all the supported camera settings.

void QCamera::searchAndLock ( QCamera::LockTypes locks )

slot

Locks the camera settings with the requested locks, including focusing in the single autofocus mode, exposure and white balance if the exposure and white balance modes are not manual.

The camera settings are usually locked before taking one or multiple still images, in response to the shutter button being half pressed.

The QCamera::locked() signal is emitted when camera settings are successfully locked otherwise QCamera::lockFailed() is emitted. QCamera also emits lockStatusChanged(QCamera::LockType, QCamera::LockStatus) on individual lock status changes and lockStatusChanged(QCamera::LockStatus) signal on composite status changes.

Locking serves two roles:

Initializes calculation of automatic parameters (focusing, calculating the correct exposure and white balance)
Allows keeping some or all of those parameters fixed during multiple shots

If the camera does not support keeping one of parameters between shots the related lock state changes to QCamera::Unlocked. It is also acceptable to relock already locked settings, depending on the lock parameter this initiates new focusing, exposure or white balance calculation.

void QCamera::setCaptureMode ( QCamera::CaptureModes mode )

slot

Sets the value of the property to mode.

void QCamera::setViewfinder ( QAbstractVideoSurface * surface )

Sets a video surface as the viewfinder of a camera. If a viewfinder has already been set on the camera the new surface will replace it.

void QCamera::setViewfinder ( QGraphicsVideoItem * viewfinder )

Sets the QGraphicsVideoItem based camera viewfinder. The previously set viewfinder is detached.

void QCamera::setViewfinder ( QVideoWidget * viewfinder )

Sets the QVideoWidget based camera viewfinder. The previously set viewfinder is detached.

void QCamera::setViewfinderSettings ( const QCameraViewfinderSettings & settings )

Sets the viewfinder settings. If some parameters are not specified, or null settings are passed, the camera will choose default values. If the camera is used to capture videos or images, the viewfinder settings might be ignored if they conflict with the capture settings. You can check the actual viewfinder settings once the camera is in the QCamera::ActiveStatus status.

Changing the viewfinder settings while the camera is in the QCamera::ActiveState state may cause the camera to be restarted.

See also: viewfinderSettings(), supportedViewfinderResolutions(), supportedViewfinderFrameRateRanges(), supportedViewfinderPixelFormats()

void QCamera::start ( )

slot

Starts the camera. State is changed to QCamera::ActiveState if camera is started successfully, otherwise error() signal is emitted.

While the camera state is changed to QCamera::ActiveState, starting the camera service can be asynchronous with the actual status reported with QCamera::status property.

State QCamera::state ( ) const

Returns the value of the property.

void QCamera::stateChanged ( QCamera::State state )

signal

Signals the camera state has changed. Usually the state changes is caused by calling load(), unload(), start() and stop(), but the state can also be changed change as a result of camera error.

Status QCamera::status ( ) const

Returns the value of the property.

void QCamera::statusChanged ( QCamera::Status status )

signal

Signals the camera status has changed.

void QCamera::stop ( )

slot

Stops the camera. The camera state is changed from QCamera::ActiveState to QCamera::LoadedState.

QCamera::LockTypes QCamera::supportedLocks ( ) const

Returns the lock types the current camera supports.

QList< FrameRateRange > QCamera::supportedViewfinderFrameRateRanges ( const QCameraViewfinderSettings & settings = QCameraViewfinderSettings() ) const

Returns a list of supported viewfinder frame rate ranges. If non null viewfinder settings are passed, the returned list is reduced to frame rate ranges supported with partial settings applied. The camera must be loaded before calling this function otherwise the returned list is empty.

See also: QCameraViewfinderSettings::minimumFrameRate(), QCameraViewfinderSettings::maximumFrameRate(), setViewfinderSettings()

QList< QVideoFrame::PixelFormat > QCamera::supportedViewfinderPixelFormats ( const QCameraViewfinderSettings & settings = QCameraViewfinderSettings() ) const

Returns a list of supported viewfinder pixel formats. If non null viewfinder settings are passed, the returned list is reduced to pixel formats supported with partial settings applied. The camera must be loaded before calling this method otherwise the returned list is empty.

See also: QCameraViewfinderSettings::pixelFormat(), setViewfinderSettings()

QList< QSize > QCamera::supportedViewfinderResolutions ( const QCameraViewfinderSettings & settings = QCameraViewfinderSettings() ) const

Returns a list of supported viewfinder resolutions. If non null viewfinder settings are passed, the returned list is reduced to resolutions supported with partial settings applied. The camera must be loaded before calling this method, otherwise the returned list is empty.

See also: QCameraViewfinderSettings::resolution(), setViewfinderSettings()

QList< QCameraViewfinderSettings > QCamera::supportedViewfinderSettings ( const QCameraViewfinderSettings & settings = QCameraViewfinderSettings() ) const

Returns a list of supported viewfinder settings. The list is ordered by preference, preferred settings come first. The camera must be loaded before calling this function, otherwise the returned list is empty.

The optional settings argument can be used to conveniently filter the results. If settings is non null, the returned list is reduced to settings matching the given partial settings.

See also: setViewfinderSettings(), supportedViewfinderResolutions(), supportedViewfinderFrameRateRanges(), supportedViewfinderPixelFormats()

void QCamera::unload ( )

slot

Close the camera device and deallocate the related resources. The camera state is changed to QCamera::UnloadedStatus.

void QCamera::unlock ( )

slot

Unlock all the requested camera locks.

void QCamera::unlock ( QCamera::LockTypes locks )

slot

Unlocks the camera settings specified with locks or cancel the current locking if one is active.

QCameraViewfinderSettings QCamera::viewfinderSettings ( ) const

Returns the viewfinder settings being used by the camera. Settings may change when the camera is started, for example if the viewfinder settings are undefined or if unsupported values are set.

If viewfinder settings are not supported by the camera, it always returns a null QCameraViewfinderSettings object.

See also: setViewfinderSettings()

Property Documentation

QCamera::captureMode

The type of media (video or still images), the camera is configured to capture.

It is allowed to change capture mode in any camera state, but if the camera is currently active, changing capture mode is likely to lead to camera status changed to QCamera::LoadedStatus, QCamera::LoadingStatus, and when the camera is ready to QCamera::ActiveStatus.
