Create a new StreamedMediaChannel object.

Parameters

connection	Connection owning this channel, and specifying the service.
objectPath	The channel object path.
immutableProperties	The channel immutable properties.

Returns: A StreamedMediaChannelPtr object pointing to the newly created StreamedMediaChannel object.

bool Tp::StreamedMediaChannel::awaitingLocalAnswer ( ) const

Return whether this channel is awaiting local answer.

This method requires StreamedMediaChannel::FeatureCore to be ready.

Returns: true if awaiting local answer, false otherwise.

See also: awaitingRemoteAnswer(), acceptCall()

bool Tp::StreamedMediaChannel::awaitingRemoteAnswer ( ) const

Return whether this channel is awaiting remote answer.

Returns: true if awaiting remote answer, false otherwise.

See also: awaitingLocalAnswer()

PendingOperation * Tp::StreamedMediaChannel::acceptCall ( )

Accept an incoming call.

PendingOperation * Tp::StreamedMediaChannel::hangupCall ( )

Request that the call is ended.

This method requires StreamedMediaChannel::FeatureCore to be ready.

Returns: A PendingOperation which will emit PendingOperation::finished when the call has finished.

StreamedMediaStreams Tp::StreamedMediaChannel::streams ( ) const

Return a list of media streams in this channel.

This methods requires StreamedMediaChannel::FeatureStreams to be ready.

Returns: A list of pointers to StreamedMediaStream objects.

See also: streamAdded(), streamRemoved(), streamsForType(), requestStreams()

StreamedMediaStreams Tp::StreamedMediaChannel::streamsForType ( MediaStreamType type ) const

Return a list of media streams in this channel for the given type type.

This methods requires StreamedMediaChannel::FeatureStreams to be ready.

Parameters

type	The interested type.

Returns: A list of pointers to StreamedMediaStream objects.

See also: streamAdded(), streamRemoved(), streams(), requestStreams()

PendingStreamedMediaStreams * Tp::StreamedMediaChannel::requestStream	(	const ContactPtr &	contact,
		MediaStreamType	type
	)

Request that media streams be established to exchange the given type type of media with the given contact contact.

This methods requires StreamedMediaChannel::FeatureStreams to be ready.

Returns: A PendingStreamedMediaStreams which will emit PendingStreamedMediaStreams::finished when the call has finished.

See also: streamAdded(), streams(), streamsForType()

PendingStreamedMediaStreams * Tp::StreamedMediaChannel::requestStreams	(	const ContactPtr &	contact,
		QList< MediaStreamType >	types
	)

Request that media streams be established to exchange the given types types of media with the given contact contact.

This methods requires StreamedMediaChannel::FeatureStreams to be ready.

Returns: A PendingStreamedMediaStreams which will emit PendingStreamedMediaStreams::finished when the call has finished.

See also: streamAdded(), streams(), streamsForType()

PendingOperation * Tp::StreamedMediaChannel::removeStream ( const StreamedMediaStreamPtr & stream )

Remove the specified media stream from this channel.

This methods requires StreamedMediaChannel::FeatureStreams to be ready.

Parameters

stream Media stream to remove.

Returns: A PendingOperation which will emit PendingOperation::finished when the call has finished.

See also: streamRemoved(), streams(), streamsForType()

PendingOperation * Tp::StreamedMediaChannel::removeStreams ( const StreamedMediaStreams & streams )

Remove the specified media streams from this channel.

This methods requires StreamedMediaChannel::FeatureStreams to be ready.

Parameters

streams List of media streams to remove.

Returns: A PendingOperation which will emit PendingOperation::finished when the call has finished.

See also: streamRemoved(), streams(), streamsForType()

bool Tp::StreamedMediaChannel::handlerStreamingRequired ( ) const

Check whether media streaming by the handler is required for this channel.

For channels with the TP_QT_IFACE_CHANNEL_INTERFACE_MEDIA_SIGNALLING interface, the main handler of the channel is responsible for doing the actual streaming, for instance by calling createFarsightChannel(channel) from TelepathyQt-Farsight library and using the telepathy-farsight API on the resulting TfChannel.

This method requires StreamedMediaChannel::FeatureCore to be ready.

Returns: true if required, false otherwise.

LocalHoldState Tp::StreamedMediaChannel::localHoldState ( ) const

Return the local hold state for this channel.

Whether the local user has placed this channel on hold.

This method requires StreamedMediaChannel::FeatureHoldState to be ready.

Returns: The local hold state as LocalHoldState.

See also: requestHold(), localHoldStateChanged()

LocalHoldStateReason Tp::StreamedMediaChannel::localHoldStateReason ( ) const

Return the reason why localHoldState() changed to its current value.

This method requires StreamedMediaChannel::FeatureLocalHoldState to be ready.

Returns: The local hold state reason as LocalHoldStateReason.

See also: requestHold(), localHoldStateChanged()

PendingOperation * Tp::StreamedMediaChannel::requestHold ( bool hold )

Request that the channel be put on hold (be instructed not to send any media streams to you) or be taken off hold.

If the CM can immediately tell that the requested state change could not possibly succeed, the resulting PendingOperation will fail with error code TP_QT_ERROR_NOT_AVAILABLE. If the requested state is the same as the current state, the resulting PendingOperation will finish successfully.

Otherwise, the channel's local hold state will change to LocalHoldStatePendingHold or LocalHoldStatePendingUnhold (as appropriate), then the resulting PendingOperation will finish successfully.

The eventual success or failure of the request is indicated by a subsequent localHoldStateChanged() signal, changing the local hold state to LocalHoldStateHeld or LocalHoldStateUnheld.

If the channel has multiple streams, and the connection manager succeeds in changing the hold state of one stream but fails to change the hold state of another, it will attempt to revert all streams to their previous hold states.

If the channel does not support the TP_QT_IFACE_CHANNEL_INTERFACE_HOLD interface, the PendingOperation will fail with error code TP_QT_ERROR_NOT_IMPLEMENTED.

Parameters

hold	A boolean indicating whether or not the channel should be on hold

Returns: A PendingOperation which will emit PendingOperation::finished when the request finishes.

const Feature Tp::StreamedMediaChannel::FeatureStreams

static

Feature used in order to access media stream specific methods.

See media stream specific methods' documentation for more details.
