Member Function Documentation

◆ staticInterfaceName()

static QLatin1String Tp::Client::CallStreamInterfaceMediaInterface::staticInterfaceName ( )

inlinestatic

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

Returns: The D-Bus interface name.

◆ requestPropertySendingState()

Tp::PendingVariant* Tp::Client::CallStreamInterfaceMediaInterface::requestPropertySendingState ( ) const

inline

Asynchronous getter for the remote object property SendingState of type uint.

Indicates whether the streaming implementation is/should be sending media for this stream. The streaming implementation should be able to rely on reading this value and listening to SendingStateChanged to determine whether it should be sending media or not. It should not need to listen to the Hold interfaces on the Call/Content. Feedback on success should be given via CompleteSendingStateChange. Failures should be reported via ReportSendingFailure.

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

◆ requestPropertyReceivingState()

Tp::PendingVariant* Tp::Client::CallStreamInterfaceMediaInterface::requestPropertyReceivingState ( ) const

inline

Asynchronous getter for the remote object property ReceivingState of type uint.

The counterpart of SendingState. Indicates whether the streaming implementation is/should be expecting to receive media for this stream. The CM should only tell the streaming implementation to stop receiving if it has been told to put the stream on hold, or the stream has been removed from the call.

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

◆ requestPropertyTransport()

Tp::PendingVariant* Tp::Client::CallStreamInterfaceMediaInterface::requestPropertyTransport ( ) const

inline

Asynchronous getter for the remote object property Transport of type uint.

The transport for this stream.

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

◆ requestPropertyLocalCandidates()

Tp::PendingVariant* Tp::Client::CallStreamInterfaceMediaInterface::requestPropertyLocalCandidates ( ) const

inline

Asynchronous getter for the remote object property LocalCandidates of type Tp::CandidateList.

[FIXME]. Change notification is via the LocalCandidatesAdded signal.

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

◆ requestPropertyLocalCredentials()

Tp::PendingVariant* Tp::Client::CallStreamInterfaceMediaInterface::requestPropertyLocalCredentials ( ) const

inline

Asynchronous getter for the remote object property LocalCredentials of type Tp::StreamCredentials.

The local credentials are sent to the remote site over the signalling protocol. They are used in ICE to make sure that the connectivity checks come from the right peer. Change notification is via the LocalCredentialsChanged signal. This property will be a pair of empty strings if ICE has not yet been started.

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

◆ requestPropertySTUNServers()

Tp::PendingVariant* Tp::Client::CallStreamInterfaceMediaInterface::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. Change notification is via the STUNServersChanged() signal. 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.

◆ requestPropertyRelayInfo()

Tp::PendingVariant* Tp::Client::CallStreamInterfaceMediaInterface::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. Well-known 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 Transport property: if Transport is ICE, tls means TLS over TCP as referenced by ICE draft 19, and if Transport 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

unique-id - s

A string identifying the relay server. If two RelayInfo entries have the same unique-id, but different types, there is usually little point in connecting to both. Use priority to determine which version to prefer in this case. Can also be used by the streaming implementation to avoid connecting to the same relay multiple times if relaying is required for both audio and video.

priority - u

A number determining which version of a server to prefer (if multiple are present with the same unique-id, the one with the highest priority should be used, or the streaming implementation should use the one whose type has the most desirable properties)

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 Transport property. If Transport is ICE, this is a TURN server; if Transport 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.

Change notification is given via the RelayInfoChanged() signal.

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

◆ requestPropertyHasServerInfo()

Tp::PendingVariant* Tp::Client::CallStreamInterfaceMediaInterface::requestPropertyHasServerInfo ( ) const

inline

Asynchronous getter for the remote object property HasServerInfo of type bool.

True if all the initial information about STUN servers and Relay servers has been retrieved. Change notification is via the ServerInfoRetrieved() signal.

Streaming implementations that can't cope with STUN and relay servers being added later SHOULD wait for this property to become true before proceeding.

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

◆ requestPropertyEndpoints()

Tp::PendingVariant* Tp::Client::CallStreamInterfaceMediaInterface::requestPropertyEndpoints ( ) const

inline

Asynchronous getter for the remote object property Endpoints of type Tp::ObjectPathList.

The list of Endpoint objects that exist for this stream. Change notification is via the EndpointsChanged signal.

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

◆ requestPropertyICERestartPending()

Tp::PendingVariant* Tp::Client::CallStreamInterfaceMediaInterface::requestPropertyICERestartPending ( ) const

inline

Asynchronous getter for the remote object property ICERestartPending of type bool.

State recovery for ICERestartRequested. Set when the signal is emitted, and unset when SetCredentials is called. Useful for debugging.

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

◆ requestAllProperties()

Tp::PendingVariantMap* Tp::Client::CallStreamInterfaceMediaInterface::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.
