## Member Function Documentation

static QLatin1String Tp::Client::CallContentInterfaceMediaInterface::staticInterfaceName | ( |  | ) |

inline static

Returns the name of the interface "org.freedesktop.Telepathy.Call1.Content.Interface.Media", which this class represents.

Returns
  The D-Bus interface name.

Tp::PendingVariant* Tp::Client::CallContentInterfaceMediaInterface::requestPropertyRemoteMediaDescriptions | ( |  | ) | const

inline

Asynchronous getter for the remote object property `RemoteMediaDescriptions` of type `Tp::ContactMediaDescriptionPropertiesMap`.

A map from contact handles to descriptions supported by that contact. Keys of this map will appear in at most one RemoteMembers. See RemoteContact for more details on how to map between MediaDescriptions and Streams.

Returns
  A pending variant which will emit finished when the property has been retrieved.

Tp::PendingVariant* Tp::Client::CallContentInterfaceMediaInterface::requestPropertyLocalMediaDescriptions | ( |  | ) | const

inline

Asynchronous getter for the remote object property `LocalMediaDescriptions` of type `Tp::ContactMediaDescriptionPropertiesMap`.

A map from contact handles to the descriptions the local side responsed with.

Returns
  A pending variant which will emit finished when the property has been retrieved.

Tp::PendingVariant* Tp::Client::CallContentInterfaceMediaInterface::requestPropertyMediaDescriptionOffer | ( |  | ) | const

inline

Asynchronous getter for the remote object property `MediaDescriptionOffer` of type `Tp::MediaDescriptionOffer`.

The object path to the current CallContentMediaDescriptionInterface object, its CallContentMediaDescriptionInterface::RemoteContact and a mapping of the MediaDescriptions properties. If the object path is "/" then there isn't an outstanding content description, and the mapping MUST be empty.

Having all CallContentMediaDescriptionInterface properties here saves a D-Bus round-trip - it shouldn't be necessary to get these properties from the Content MediaDescription object, in practice.

Change notification is via the NewMediaDescriptionOffer() and MediaDescriptionOfferDone() signals.

Returns
  A pending variant which will emit finished when the property has been retrieved.

Tp::PendingVariant* Tp::Client::CallContentInterfaceMediaInterface::requestPropertyPacketization | ( |  | ) | const

inline

Asynchronous getter for the remote object property `Packetization` of type `uint`.

The packetization method in use for this content.

Returns
  A pending variant which will emit finished when the property has been retrieved.

Tp::PendingVariant* Tp::Client::CallContentInterfaceMediaInterface::requestPropertyCurrentDTMFEvent | ( |  | ) | const

inline

Asynchronous getter for the remote object property `CurrentDTMFEvent` of type `uchar`.

The currently requested DTMF event (for state-recoverability of DTMFChangeRequested). Should be ignored if CurrentDTMFState is None.

Returns
  A pending variant which will emit finished when the property has been retrieved.

Tp::PendingVariant* Tp::Client::CallContentInterfaceMediaInterface::requestPropertyCurrentDTMFState | ( |  | ) | const

inline

Asynchronous getter for the remote object property `CurrentDTMFState` of type `uint`.

The current DTMF state (for state-recoverability of DTMFChangeRequested).

Returns
  A pending variant which will emit finished when the property has been retrieved.

Tp::PendingVariantMap* Tp::Client::CallContentInterfaceMediaInterface::requestAllProperties | ( |  | ) | const

inline

Request all of the DBus properties on the interface.

Returns
  A pending variant map which will emit finished when the properties have been retrieved.

QDBusPendingReply Tp::Client::CallContentInterfaceMediaInterface::UpdateLocalMediaDescription | ( | const QVariantMap & | mediaDescription,
|  | int | timeout = `-1`
| ) |  |

inline slot

Begins a call to the D-Bus method `UpdateLocalMediaDescription` on the remote object.

Update the local codec mapping and other interfaces of the MediaDescription. This method should only be used during an existing call to update the local media description. This may trigger a re-negotiation which may result in new new MediaDescriptionOffers if the "FurtherNegotiationRequired" property is TRUE. Otherwise, only parameters which strictly describe the media being sent can be changed.

Note that timeout is ignored as of now. It will be used once http://bugreports.qt.nokia.com/browse/QTBUG-11775 is fixed.

Parameters

  mediaDescription

      The updated media description that the local side wants to use.

  timeout | The timeout in milliseconds.

QDBusPendingReply Tp::Client::CallContentInterfaceMediaInterface::AcknowledgeDTMFChange | ( | uchar | event,
|  | uint | state,
|  | int | timeout = `-1`
| ) |  |

inline slot

Begins a call to the D-Bus method `AcknowledgeDTMFChange` on the remote object.

Called by the streaming implementation in response to DTMFChangeRequested to confirm that it has started or stopped sending the event in question.

Note that timeout is ignored as of now. It will be used once http://bugreports.qt.nokia.com/browse/QTBUG-11775 is fixed.

Parameters

  event

      The event referred to in the corresponding DTMFChangeRequested
      signal.

  state

      Either Sending or None.

  timeout | The timeout in milliseconds.

QDBusPendingReply Tp::Client::CallContentInterfaceMediaInterface::Fail | ( | const Tp::CallStateReason & | reason,
|  | int | timeout = `-1`
| ) |  |

inline slot

Begins a call to the D-Bus method `Fail` on the remote object.

Signal an unrecoverable error for this content, and remove it.

Note that timeout is ignored as of now. It will be used once http://bugreports.qt.nokia.com/browse/QTBUG-11775 is fixed.

Parameters

  reason

      A reason struct describing the error.

  timeout | The timeout in milliseconds.

void Tp::Client::CallContentInterfaceMediaInterface::NewMediaDescriptionOffer | ( | const QDBusObjectPath & | mediaDescription,
|  | const QVariantMap & | properties
| ) |  |

signal

Represents the signal `NewMediaDescriptionOffer` on the remote object.

Emitted when a new CallContentMediaDescriptionInterface appears. The streaming >implementation MUST respond by calling the CallContentMediaDescriptionInterface::Accept() or CallContentMediaDescriptionInterface::Reject() method on the description object appeared.

Emission of this signal indicates that the MediaDescriptionOffer property has changed to `(Description, Contact, MediaDescriptionProperties)`.

When the MediaDescriptionOffer has been dealt with then CallContentInterfaceMediaInterface::MediaDescriptionOfferDone() must be emitted before CallContentInterfaceMediaInterface::NewMediaDescriptionOffer() is emitted again.

Parameters

  mediaDescription

      The object path of the new media description. This replaces any
      previous media description.

  properties

      The immutable properties of the remote media description. Having
      all the MediaDescription properties here saves a D-Bus round-trip -
      it shouldn&apos;t be necessary to get the properties from the
      MediaDescription object, in practice.

void Tp::Client::CallContentInterfaceMediaInterface::MediaDescriptionOfferDone | ( |  | ) |

signal

Represents the signal `MediaDescriptionOfferDone` on the remote object.

Emitted when a CallContentMediaDescriptionInterface has been handled.

Emission of this signal indicates that the MediaDescriptionOffer property has changed to `("/", 0, {})`.

void Tp::Client::CallContentInterfaceMediaInterface::LocalMediaDescriptionChanged | ( | const QVariantMap & | updatedMediaDescription | ) |

signal

Represents the signal `LocalMediaDescriptionChanged` on the remote object.

Change notification for CallContentInterfaceMediaInterface::LocalMediaDescriptions

Parameters

  updatedMediaDescription | The local content description that was updated

void Tp::Client::CallContentInterfaceMediaInterface::RemoteMediaDescriptionsChanged | ( | const Tp::ContactMediaDescriptionPropertiesMap & | updatedMediaDescriptions | ) |

signal

Represents the signal `RemoteMediaDescriptionsChanged` on the remote object.

Change notification for CallContentInterfaceMediaInterface::RemoteMediaDescriptions

Parameters

  updatedMediaDescriptions | The remote content descriptions that were updated

void Tp::Client::CallContentInterfaceMediaInterface::MediaDescriptionsRemoved | ( | const Tp::UIntList & | removedMediaDescriptions | ) |

void Tp::Client::CallContentInterfaceMediaInterface::DTMFChangeRequested | ( | uchar | event,
|  | uint | state
| ) |  |

signal

Represents the signal `DTMFChangeRequested` on the remote object.

Used by the CM to relay instructions from Channel.Interface.DTMF to the streaming implementation. If any contact in this call supports the telephone-event codec in their MediaDescription, this event should be sent as outlined in RFC 4733. Otherwise, it should be sent as an audible tone.

Parameters

  event

      The event to send (or stop sending).

  state

      Either Pending_Send or Pending_Stop_Sending.
