## Member Function Documentation

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

inline static

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

Returns
  The D-Bus interface name.

Tp::PendingVariant* Tp::Client::MediaStreamHandlerInterface::requestPropertySTUNServers | ( |  | ) | const

inline

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

The IP addresses of possible STUN servers to use for NAT traversal, as dotted-quad IPv4 address literals or RFC2373 IPv6 address literals. This property cannot change once the stream has been created, so there is no change notification. The IP addresses MUST NOT be given as DNS hostnames. High-quality connection managers already need an asynchronous DNS resolver, so they might as well resolve this name to an IP to make life easier for streaming implementations.

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

Tp::PendingVariant* Tp::Client::MediaStreamHandlerInterface::requestPropertyCreatedLocally | ( |  | ) | const

inline

Asynchronous getter for the remote object property `CreatedLocally` of type `bool`.

True if we were the creator of this stream, false otherwise. This information is needed for some nat traversal mechanisms, such as ICE-UDP, where the creator gets the role of the controlling agent.

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

Tp::PendingVariant* Tp::Client::MediaStreamHandlerInterface::requestPropertyNATTraversal | ( |  | ) | const

inline

Asynchronous getter for the remote object property `NATTraversal` of type `QString`.

The transport (NAT traversal technique) to be used for this stream. Well-known values include:

none
  Raw UDP, with or without STUN, should be used. If the STUNServers property is non-empty, STUN SHOULD be used.
stun
  A deprecated synonym for 'none'.
gtalk-p2p
  Google Talk peer-to-peer connectivity establishment should be used, as implemented in libjingle 0.3.
ice-udp
  Interactive Connectivity Establishment should be used, as defined by the IETF MMUSIC working group.
wlm-8.5
  The transport used by Windows Live Messenger 8.5 or later, which resembles ICE draft 6, should be used.
wlm-2009
  The transport used by Windows Live Messenger 2009 or later, which resembles ICE draft 19, should be used.

This property cannot change once the stream has been created, so there is no change notification.

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

Tp::PendingVariant* Tp::Client::MediaStreamHandlerInterface::requestPropertyRelayInfo | ( |  | ) | const

inline

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

A list of mappings describing TURN or Google relay servers available for the client to use in its candidate gathering, as determined from the protocol. Map keys are:

`ip` - s
  The IP address of the relay server as a dotted-quad IPv4 address literal or an RFC2373 IPv6 address literal. This MUST NOT be a DNS hostname.
  High-quality connection managers already need an asynchronous DNS resolver, so they might as well resolve this name to an IP and make life easier for streaming implementations.
`type` - s

  Either `udp` for UDP (UDP MUST be assumed if this key is omitted), `tcp` for TCP, or `tls`.

  The precise meaning of this key depends on the NATTraversal property: if NATTraversal is `ice-udp`, `tls` means TLS over TCP as referenced by ICE draft 19, and if NATTraversal is `gtalk-p2p`, `tls` means a fake SSL session over TCP as implemented by libjingle.

`port` - q
  The UDP or TCP port of the relay server as an ASCII unsigned integer
`username` - s
  The username to use
`password` - s
  The password to use
`component` - u
  The component number to use this relay server for, as an ASCII unsigned integer; if not included, this relay server may be used for any or all components.
  In ICE draft 6, as used by Google Talk, credentials are only valid once, so each component needs relaying separately.

An equivalent of the gtalk-p2p-relay-token property on MediaSignalling channels is not included here. The connection manager should be responsible for making the necessary HTTP requests to turn the token into a username and password.

The type of relay server that this represents depends on the value of the NATTraversal property. If NATTraversal is ice-udp, this is a TURN server; if NATTraversal is gtalk-p2p, this is a Google relay server; otherwise, the meaning of RelayInfo is undefined.

If relaying is not possible for this stream, the list is empty.

This property cannot change once the stream has been created, so there is no change notification.

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

Tp::PendingVariantMap* Tp::Client::MediaStreamHandlerInterface::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::MediaStreamHandlerInterface::CodecChoice | ( | uint | codecID,
|  | int | timeout = `-1`
| ) |  |

inline slot

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

Inform the connection manager of codec used to receive data.

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

Parameters

  timeout | The timeout in milliseconds.

QDBusPendingReply Tp::Client::MediaStreamHandlerInterface::Error | ( | uint | errorCode,
|  | const QString & | message,
|  | int | timeout = `-1`
| ) |  |

inline slot

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

Inform the connection manager that an error occured in this stream. The connection manager should emit the StreamError signal for the stream on the relevant channel, and remove the stream from the session.

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

Parameters

  errorCode

      ID of error, from the MediaStreamError enumeration

  message

      String describing the error

  timeout | The timeout in milliseconds.

QDBusPendingReply Tp::Client::MediaStreamHandlerInterface::NativeCandidatesPrepared | ( | int | timeout = `-1` | ) |

inline slot

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

Informs the connection manager that all possible native candisates have been discovered for the moment.

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

Parameters

  timeout | The timeout in milliseconds.

QDBusPendingReply Tp::Client::MediaStreamHandlerInterface::NewActiveCandidatePair | ( | const QString & | nativeCandidateID,
|  | const QString & | remoteCandidateID,
|  | int | timeout = `-1`
| ) |  |

inline slot

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

Informs the connection manager that a valid candidate pair has been discovered and streaming is in progress.

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

Parameters

  timeout | The timeout in milliseconds.

QDBusPendingReply Tp::Client::MediaStreamHandlerInterface::NewActiveTransportPair | ( | const QString & | nativeCandidateID,
|  | const Tp::MediaStreamHandlerTransport & | nativeTransport,
|  | const QString & | remoteCandidateID,
|  | const Tp::MediaStreamHandlerTransport & | remoteTransport,
|  | int | timeout = `-1`
| ) |  |

inline slot

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

Informs the connection manager that a valid transport pair has been discovered and streaming is in progress. Component id MUST be the same for both transports and the pair is only valid for that component. The connection manager might need to send the details of the active transport pair (e.g. c and o parameters of SDP body need to contain address of selected native RTP transport as stipulated by RFC 5245). However, the candidate ID might not be enough to determine these info if the transport was found after NativeCandidatesPrepared has been called (e.g. peer reflexive ICE candidate). This method must be called before NewActiveCandidatePair. This way, connection managers supporting this method can safely ignore subsequent NewActiveCandidatePair call. Connection managers SHOULD NOT implement this method unless they need to inform the peer about selected transports. As a result, streaming implementations MUST NOT treat errors raised by this method as fatal. Usually, connection managers only need to do one answer/offer round-trip. However, some protocols give the possibility to to send an updated offer (e.g. ICE defines such mechanism to avoid some race conditions and to properly set the state of gateway devices).

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

Parameters

  timeout | The timeout in milliseconds.

QDBusPendingReply Tp::Client::MediaStreamHandlerInterface::NewNativeCandidate | ( | const QString & | candidateID,
|  | const Tp::MediaStreamHandlerTransportList & | transports,
|  | int | timeout = `-1`
| ) |  |

inline slot

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

Inform this MediaStreamHandler that a new native transport candidate has been ascertained.

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

Parameters

  candidateID

      String identifier for this candidate

  transports

  Array of transports for this candidate, with fields:
  - component number
  - IP address (as a string)
  - port
  - base network protocol (one of the values of MediaStreamBaseProto)
  - proto subtype (e.g. RTP)
  - proto profile (e.g. AVP)
  - our preference value of this transport (double in range 0.0-1.0 inclusive); 1 signals the most preferred transport
  - transport type, one of the values of MediaStreamTransportType
  - username if authentication is required
  - password if authentication is required

  timeout | The timeout in milliseconds.

QDBusPendingReply Tp::Client::MediaStreamHandlerInterface::Ready | ( | const Tp::MediaStreamHandlerCodecList & | codecs,
|  | int | timeout = `-1`
| ) |  |

inline slot

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

Inform the connection manager that a client is ready to handle this StreamHandler. Also provide it with info about all supported codecs.

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

Parameters

  codecs

      Locally-supported codecs.

  timeout | The timeout in milliseconds.

QDBusPendingReply Tp::Client::MediaStreamHandlerInterface::SetLocalCodecs | ( | const Tp::MediaStreamHandlerCodecList & | codecs,
|  | int | timeout = `-1`
| ) |  |

inline slot

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

Used to provide codecs after Ready(), so the media client can go ready for an incoming call and exchange candidates/codecs before knowing what local codecs are available.

This is useful for gatewaying calls between two connection managers. Given an incoming call, you need to call Ready() to get the remote codecs before you can use them as the "local" codecs to place the outgoing call, and hence receive the outgoing call's remote codecs to use as the incoming call's "local" codecs.

In this situation, you would pass an empty list of codecs to the incoming call's Ready method, then later call SetLocalCodecs on the incoming call in order to respond to the offer.

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

Parameters

  codecs

      Locally-supported codecs

  timeout | The timeout in milliseconds.

QDBusPendingReply Tp::Client::MediaStreamHandlerInterface::StreamState | ( | uint | state,
|  | int | timeout = `-1`
| ) |  |

inline slot

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

Informs the connection manager of the stream's current state, as as specified in Channel.Type.StreamedMedia::ListStreams.

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

Parameters

  timeout | The timeout in milliseconds.

QDBusPendingReply Tp::Client::MediaStreamHandlerInterface::SupportedCodecs | ( | const Tp::MediaStreamHandlerCodecList & | codecs,
|  | int | timeout = `-1`
| ) |  |

inline slot

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

Inform the connection manager of the supported codecs for this session. This is called after the connection manager has emitted SetRemoteCodecs to notify what codecs are supported by the peer, and will thus be an intersection of all locally supported codecs (passed to Ready) and those supported by the peer.

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

Parameters

  codecs

      Locally supported codecs.

  timeout | The timeout in milliseconds.

QDBusPendingReply Tp::Client::MediaStreamHandlerInterface::CodecsUpdated | ( | const Tp::MediaStreamHandlerCodecList & | codecs,
|  | int | timeout = `-1`
| ) |  |

inline slot

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

Inform the connection manager that the parameters of the supported codecs for this session have changed. The connection manager should send the new parameters to the remote contact. This is required for H.264 and Theora, for example.

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

Parameters

  codecs

      Locally supported codecs, which SHOULD be the same as were
      previously in effect, but possibly with different parameters.

|  | int | timeout = `-1`
| ) |  |

inline slot

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

Notify the connection manager that the stream's hold state has been changed successfully in response to SetStreamHeld.

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

Parameters

  held

      If true, the stream is now on hold.

  timeout | The timeout in milliseconds.

QDBusPendingReply Tp::Client::MediaStreamHandlerInterface::UnholdFailure | ( | int | timeout = `-1` | ) |

inline slot

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

Notify the connection manager that an attempt to reacquire the necessary hardware or software resources to unhold the stream, in response to SetStreamHeld, has failed.

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

Parameters

void Tp::Client::MediaStreamHandlerInterface::AddRemoteCandidate | ( | const QString & | candidateID,
|  | const Tp::MediaStreamHandlerTransportList & | transports
| ) |  |

signal

Represents the signal `AddRemoteCandidate` on the remote object.

Signal emitted when the connection manager wishes to inform the client of a new remote candidate.

Signal emitted when the connection manager wishes the stream to be closed.

void Tp::Client::MediaStreamHandlerInterface::RemoveRemoteCandidate | ( | const QString & | candidateID | ) |

signal

Represents the signal `RemoveRemoteCandidate` on the remote object.

Signal emitted when the connection manager wishes to inform the client that the remote end has removed a previously usable candidate. It seemed like a good idea at the time, but wasn't.

Parameters

  candidateID

      String identifier for remote candidate to drop

void Tp::Client::MediaStreamHandlerInterface::SetActiveCandidatePair | ( | const QString & | nativeCandidateID,
|  | const QString & | remoteCandidateID
| ) |  |

signal

Represents the signal `SetActiveCandidatePair` on the remote object.

Emitted by the connection manager to inform the client that a valid candidate pair has been discovered by the remote end and streaming is in progress.

void Tp::Client::MediaStreamHandlerInterface::SetRemoteCandidateList | ( | const Tp::MediaStreamHandlerCandidateList & | remoteCandidates | ) |

signal

Represents the signal `SetRemoteCandidateList` on the remote object.

Signal emitted when the connection manager wishes to inform the client of all the available remote candidates at once.

Parameters

  remoteCandidates

      A list of candidate id and a list of transports as defined in
      NewNativeCandidate

void Tp::Client::MediaStreamHandlerInterface::SetRemoteCodecs | ( | const Tp::MediaStreamHandlerCodecList & | codecs | ) |

signal

Represents the signal `SetRemoteCodecs` on the remote object.

Signal emitted when the connection manager wishes to inform the client of the codecs supported by the remote end. If these codecs are compatible with the remote codecs, then the client must call SupportedCodecs, otherwise call Error.

Parameters

  codecs

      Codecs supported by the remote peer.

void Tp::Client::MediaStreamHandlerInterface::SetStreamPlaying | ( | bool | playing | ) |

signal

Represents the signal `SetStreamPlaying` on the remote object.

If emitted with argument TRUE, this means that the connection manager wishes to set the stream playing; this means that the streaming implementation should expect to receive data. If emitted with argument FALSE this signal is basically meaningless and should be ignored. We're very sorry.

void Tp::Client::MediaStreamHandlerInterface::SetStreamSending | ( | bool | sending | ) |

signal

Represents the signal `SetStreamSending` on the remote object.

Signal emitted when the connection manager wishes to set whether or not the stream sends to the remote end.

void Tp::Client::MediaStreamHandlerInterface::StartTelephonyEvent | ( | uchar | event | ) |

signal

Represents the signal `StartTelephonyEvent` on the remote object.

Request that a telephony event (as defined by RFC 4733) is transmitted over this stream until StopTelephonyEvent is called.

Parameters

  event

      A telephony event code.

void Tp::Client::MediaStreamHandlerInterface::StartNamedTelephonyEvent | ( | uchar | event,
|  | uint | codecID
| ) |  |

signal

Represents the signal `StartNamedTelephonyEvent` on the remote object.

Request that a telephony event (as defined by RFC 4733) is transmitted over this stream until StopTelephonyEvent is called. This differs from StartTelephonyEvent in that you force the event to be transmitted as a RFC 4733 named event, not as sound. You can also force a specific Codec ID.

Parameters

  event

      A telephony event code as defined by RFC 4733.

  codecID

      The payload type to use when sending events. The value 0xFFFFFFFF
      means to send with the already configured event type instead of
      using the specified one.

void Tp::Client::MediaStreamHandlerInterface::StartSoundTelephonyEvent | ( | uchar | event | ) |

signal

Represents the signal `StartSoundTelephonyEvent` on the remote object.

Request that a telephony event (as defined by RFC 4733) is transmitted over this stream until StopTelephonyEvent is called. This differs from StartTelephonyEvent in that you force the event to be transmitted as sound instead of as a named event.

Parameters

  event

      A telephony event code as defined by RFC 4733.

void Tp::Client::MediaStreamHandlerInterface::StopTelephonyEvent | ( |  | ) |

signal

Represents the signal `StopTelephonyEvent` on the remote object.

Request that any ongoing telephony events (as defined by RFC 4733) being transmitted over this stream are stopped.

void Tp::Client::MediaStreamHandlerInterface::SetStreamHeld | ( | bool | held | ) |

signal

Represents the signal `SetStreamHeld` on the remote object.

Emitted when the connection manager wishes to place the stream on hold (so the streaming client should free hardware or software resources) or take the stream off hold (so the streaming client should reacquire the necessary resources).

When placing a channel's streams on hold, the connection manager SHOULD notify the remote contact that this will be done (if appropriate in the protocol) before it emits this signal.

It is assumed that relinquishing a resource will not fail. If it does, the call is probably doomed anyway.

When unholding a channel's streams, the connection manager SHOULD emit this signal and wait for success to be indicated via HoldState before it notifies the remote contact that the channel has been taken off hold.

This means that if a resource is unavailable, the remote contact will never even be told that we tried to acquire it.

Parameters

  held

      If true, the stream is to be placed on hold.

void Tp::Client::MediaStreamHandlerInterface::SetRemoteFeedbackMessages | ( | const Tp::RTCPFeedbackMessageMap & | messages | ) |

signal

Represents the signal `SetRemoteFeedbackMessages` on the remote object.

Signal emitted when the connection manager wishes to inform the client of the feedback messages supported by the remote end. This signal is emitted before SetRemoteCodecs. If the client supports any of these messages, it must call SupportedFeedbackMessages before calling SupportedCodecs.

Parameters

  messages

      Remote Feedback messages desired by the remote side

void Tp::Client::MediaStreamHandlerInterface::SetRemoteHeaderExtensions | ( | const Tp::RTPHeaderExtensionsList & | headerExtensions | ) |

signal

Represents the signal `SetRemoteHeaderExtensions` on the remote object.

Signal emitted when the connection manager wishes to inform the client of the RTP header extensions supported by the remote end. This signal is emitted before SetRemoteCodecs. If the client supports any of these messages, it must call SupportedHeaderExtensions before calling SupportedCodecs.

Parameters

  headerExtensions

      Header extensions desired by the remote side

void Tp::Client::MediaStreamHandlerInterface::invalidate | ( | Tp::DBusProxy * | proxy,
|  | const QString & | error,
|  | const QString & | message
| ) |  |

protected virtual
