Methods

Interfaces — as (DBus_Interface_List)

Read only
Added in 0.19.11.

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

(Permalink)

Name — s

Read only

The name of the content. [FIXME: rationale?]

(Permalink)

Type — u (Media_Stream_Type)

Read only

The media type of this content

(Permalink)

Creator — u (Contact_Handle)

Read only

The creator of this content

(Permalink)

Disposition — u (Call_Content_Disposition)

Read only
The disposition of this content. This property cannot change.
(Permalink)

Streams — ao

Read only

The list of Stream.DRAFT objects that exist in this content.

Rationale:

In a conference call multiple parties can share one media content (say, audio), but the streaming of that media can either be shared or separate. For example, in a multicast conference all contacts would share one stream, while in a Muji conference there would be a stream for each participant.

Change notification is via StreamAdded and StreamRemoved.

Types

Enum (Permalink)

Call_Content_Disposition — u

[FIXME]
  • None (0)
    • The content has no specific disposition
  • Early_Media (1)
    • [FIXME: what does this mean?]
  • Initial (2)

    • The content was initially part of the call. When Accept is called on the channel, all streams of this content where the self-handle's sending state in Senders is Sending_State_Pending_Send will be moved to Sending_State_Sending as if SetSending(TRUE) had been called.
