Implemented Interfaces

TpBaseMediaCallStream implements TpSvcCall1Stream and TpSvcCall1StreamInterfaceMedia.

Includes

#include <telepathy-glib/telepathy-glib.h>

Description

This base class makes it easier to write TpSvcCall1StreamInterfaceMedia implementations by implementing some of its properties and methods.

Subclasses must still implement TpBaseCallStream's virtual methods plus TpBaseMediaCallStreamClass.add_local_candidates and TpBaseMediaCallStreamClass.finish_initial_candidates.

Functions

TpBaseMediaCallStreamFinishInitialCandidatesFunc ()

gboolean
(*TpBaseMediaCallStreamFinishInitialCandidatesFunc)
                               (TpBaseMediaCallStream *self,
                                GError **error);

Signature of an implementation of TpBaseMediaCallStreamClass.finish_initial_candidates.

Parameters

self

a TpBaseMediaCallStream

  

error

a GError to fill

  

Since 0.17.5

TpBaseMediaCallStreamAddCandidatesFunc ()

GPtrArray *
(*TpBaseMediaCallStreamAddCandidatesFunc)
                               (TpBaseMediaCallStream *self,
                                const GPtrArray *candidates,
                                GError **error);

Signature of an implementation of TpBaseMediaCallStreamClass.add_local_candidates.

Implementation should validate the added candidates and return a subset (or all) of them that are accepted. Implementation should return a new GPtrArray build in a way that g_ptr_array_unref() is enough to free all its memory. It is fine to just add element pointers from candidates to the returned GPtrArray without deep-copy them.

Parameters

self

a TpBaseMediaCallStream

  

candidates

a GPtrArray of GValueArray containing candidates info

  

error

a GError to fill
