Description

This base class makes it easier to write TpSvcCallStreamInterfaceMedia 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.

Details

TpBaseMediaCallStream

typedef struct _TpBaseMediaCallStream TpBaseMediaCallStream;

A base class for media call stream implementations

Since 0.17.5

struct TpBaseMediaCallStreamClass

struct TpBaseMediaCallStreamClass {
  TpBaseMediaCallStreamReportFailureFunc report_sending_failure;
  TpBaseMediaCallStreamReportFailureFunc report_receiving_failure;
  TpBaseMediaCallStreamAddCandidatesFunc add_local_candidates;

The class structure for TpBaseMediaCallStream

TpBaseMediaCallStreamReportFailureFunc report_sending_failure;

 optional; called to indicate a failure in the outgoing portion of the stream

TpBaseMediaCallStreamReportFailureFunc report_receiving_failure;

 optional; called to indicate a failure in the incoming portion of the stream

TpBaseMediaCallStreamAddCandidatesFunc add_local_candidates;

 mandatory; called when new candidates are added

TpBaseMediaCallStreamFinishInitialCandidatesFunc finish_initial_candidates;

 optional; called when the initial batch of candidates has been added, and should now be processed/sent to the remote side

TpBaseMediaCallStreamRequestReceivingFunc request_receiving;

 optional (see "can-request-receiving"); virtual method called when user requested receiving from the given remote contact. This virtual method should be implemented instead of TpBaseCallStreamClass.request_receiving

TpBaseMediaCallStreamSetSendingFunc set_sending;

 mandatory; virtual method called when user requested to start/stop sending to remote contacts. This virtual method should be implemented instead of TpBaseCallStreamClass.set_sending

Since 0.17.5

TpBaseMediaCallStreamFinishInitialCandidatesFunc ()

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

Signature of an implementation of TpBaseMediaCallStreamClass.finish_initial_candidates.

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.
