Detailed Description

The QVideoEncoderSettingsControl class provides access to the settings of a media service that performs video encoding. If a QMediaService supports encoding video data it will implement QVideoEncoderSettingsControl. This control provides information about the limits of restricted video encoder options and allows the selection of a set of video encoder settings as specified in a QVideoEncoderSettings object.

The functionality provided by this control is exposed to application code through the QMediaRecorder class.

The interface name of QVideoEncoderSettingsControl is "com.copperspice.CS.videoEncoderSettingsControl/1.0" as defined in QVideoEncoderSettingsControl_iid.

Constructor & Destructor Documentation

QVideoEncoderSettingsControl::~QVideoEncoderSettingsControl ( )

virtual

Destroys a video encoder settings control.

QVideoEncoderSettingsControl::QVideoEncoderSettingsControl ( QObject * parent = nullptr )

explicitprotected

Create a new video encoder settings control object with the given parent.

Method Documentation

void QVideoEncoderSettingsControl::setVideoSettings ( const QVideoEncoderSettings & settings )

pure virtual

Sets the selected video encoder settings.

QList< qreal > QVideoEncoderSettingsControl::supportedFrameRates	(	const QVideoEncoderSettings &	settings = `QVideoEncoderSettings()`,
		bool *	continuous = `nullptr`
	)		const

pure virtual

Returns a list of supported frame rates.

If settings is not empty the returned list will only contain resolutions matching the given settings. If the encoder supports arbitrary frame rates within the supported range, then continuous is set to true otherwise it is set to false.

See also: QVideoEncoderSettings::frameRate()

QList< QSize > QVideoEncoderSettingsControl::supportedResolutions	(	const QVideoEncoderSettings &	settings = `QVideoEncoderSettings()`,
		bool *	continuous = `nullptr`
	)		const

pure virtual

Returns a list of supported video resolutions.

If settings is not empty the returned list will only contain resolutions matching the given settings. If the encoder supports arbitrary resolutions within the supported resolutions range, then continuous is set to true otherwise it is set to false.

See also: QVideoEncoderSettings::resolution()

QStringList QVideoEncoderSettingsControl::supportedVideoCodecs ( ) const

pure virtual

Returns the list of supported video codecs.

QString QVideoEncoderSettingsControl::videoCodecDescription ( const QString & codecName ) const

pure virtual

Returns a description of a video codecName.

QVideoEncoderSettings QVideoEncoderSettingsControl::videoSettings ( ) const

pure virtual

Returns the video encoder settings. The returned value may not match the parameter which was passed to QAudioEncoderSettingsControl::setVideoSettings() which can happen if the settings were incomplete.
