Description

One stream inside a Content.DRAFT.

Methods

(Permalink)

SetSending (b: Send) → nothing

Parameters

Set the stream to start or stop sending media from the local user to other contacts.

Possible Errors

  • Not Implemented
    • Raised when the requested method, channel, etc is not available on this connection.
(Permalink)

RequestReceiving (u: Contact, b: Receive) → nothing

Parameters

  • Contact — u (Contact_Handle)

    • Contact from which sending is requested

  • Receive — b

    • If true, request that the given contact starts to send media. If false, request that the given contact stops sending media.

Request that a remote contact stops or starts sending on this stream.

The CanRequestReceiving property defines whether the protocol allows the local user to request the other side start sending on this stream.

Possible Errors

  • Invalid Handle
    • The handle specified is unknown on this channel or connection.
  • Invalid Argument
    • The request contact is valid but is not involved in this stream.
  • Not Implemented
    • The protocol does not allow the local user to request the other side starts sending on this stream.

Signals

RemoteMembersChanged (a{uu}: Updates, au: Removed)

Changed in 0.21.2. renamed from SendersChanged to MembersChanged
Changed in 0.21.3. renamed from MembersChanged to RemoteMembersChanged

Parameters

  • Updates — a{uu} (Contact_Sending_State_Map)
    • A mapping from channel-specific handles to their updated sending state, whose keys include at least the members who were added, and the members whose states changed.
  • Removed — au (Contact_Handle_List)
    • The channel-specific handles that were removed from the keys of the RemoteMembers property, as a result of the contact leaving this stream
Emitted when RemoteMembers changes.

LocalSendingStateChanged (u: State)

Parameters

Emitted when LocalSendingState changes.

Properties

Accessed using the org.freedesktop.DBus.Properties interface.
(Permalink)

Interfaces — as (DBus_Interface_List)

Read only
This property is immutable which means that it can never change.
Added in 0.19.11.

Extra interfaces provided by this stream, such as Stream.Interface.Media.DRAFT. This SHOULD NOT include the Stream interface itself, and cannot change once the stream has been created.

(Permalink)

RemoteMembers — a{uu} (Contact_Sending_State_Map)

Read only
Changed in 0.21.2. renamed from Senders

A map from remote contacts to their sending state. The local user's sending state is shown in LocalSendingState.

Sending_State_Pending_Send indicates that another contact has asked the local user to send media.

Other contacts' handles in this map indicate whether they are sending media to the contacts in this stream. Sending_State_Pending_Send indicates contacts who are not sending but have been asked to do so.

(Permalink)

LocalSendingState — u (Sending_State)

Read only

The local user's sending state. Media sent on this stream should be assumed to be received, directly or indirectly, by every other contact in the RemoteMembers mapping. Change notification is given via the LocalSendingStateChanged signal.

Rationale:
Implementations of the first Call draft had the self handle in the RemoteMembers (then called Members) map and this showed that it's annoying having to keep track of the self handle so that it can be special-cased.

A value of Sending_State_Pending_Send for this property indicates that the other side requested the local user start sending media, which can be done by calling SetSending. When a call is accepted, all initial contents with streams that have a local sending state of Sending_State_Pending_Send are automatically set to sending. For example, on an incoming call it means you need to Accept to start the actual call, on an outgoing call it might mean you need to call Accept before actually starting the call.

CanRequestReceiving — b

Read only
This property is immutable which means that it can never change.
Added in 0.21.2.

If true, the user can request that a remote contact starts sending on this stream.

Rationale:
Not all protocols allow the user to ask the other side to start sending media.

Types

Enum (Permalink)

Sending_State — u

Enum indicating whether a contact is sending media.
  • None (0)
    • The contact is not sending media and has not been asked to do so.
  • Pending_Send (1)
    • The contact has been asked to start sending media.
  • Sending (2)
    • The contact is sending media.
  • Pending_Stop_Sending (3)
    • The contact has been asked to stop sending media.
Mapping (Permalink)

Contact_Sending_State_Map — a{uu}

A map from a contact to his or her sending state.
