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 non null video settings parameter is passed, the returned list is reduced to frame rates supported with partial settings like QVideoEncoderSettings::setCodec() or QVideoEncoderSettings::setResolution() applied.

If the encoder supports arbitrary frame rates within the supported range, 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 resolutions.

If non null video settings parameter is passed, the returned list is reduced to resolution supported with partial settings like QVideoEncoderSettings::setCodec() or QVideoEncoderSettings::setFrameRate() applied.

If the encoder supports arbitrary resolutions within the supported resolutions range, 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 codec) const
pure virtual

Returns a description of a video codec.

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.
