Implemented Interfaces

FsConference implements GstChildProxy.

Includes

#include <farstream/fs-conference.h>

Description

A Farstream conference is a conversation space that takes place between 2 or more participants. Each conference must have one or more Farstream sessions that are associated to the conference participants.

This will communicate asynchronous events to the user through GstMessage of type GST_MESSAGE_ELEMENT sent over the GstBus.

The "farstream-error" message

1

3
 
"src-object"       #GObject           The object (#FsConference, #FsSession or #FsStream) that emitted the error
"error-no"         #FsError           The Error number
"error-msg"        #gchar*            The error message

The message is sent on asynchronous errors.

Functions

fs_conference_new_session ()

FsSession *
fs_conference_new_session (FsConference *conference,
                           FsMediaType media_type,
                           GError **error);

Create a new Farstream session for the given conference.

Parameters

conference

FsConference interface of a GstElement

  

media_type

FsMediaType of the new session

  

error

location of a GError, or NULL if no error occured

  

Returns

the new FsSession that has been created. The FsSession must be unref'd by the user when closing the session.

fs_conference_new_participant ()

FsParticipant *
fs_conference_new_participant (FsConference *conference,
                               GError **error);

Create a new Farstream Participant for the type of the given conference.

Parameters

conference

FsConference interface of a GstElement

  

error

location of a GError, or NULL if no error occured

  

Returns

the new FsParticipant that has been created. The FsParticipant is owned by the user and he must unref it when he is done with it.

[transfer full]

FS_ERROR

#define FS_ERROR (fs_error_quark ())

This quark is used to denote errors coming from Farstream objects

FS_ERROR_IS_FATAL()

#define             FS_ERROR_IS_FATAL(error)

Tells the programmer if an error if fatal or not, if it returns TRUE, the error is fatal, and the object that created it should be discarded. It returns FALSE otherwise.

Parameters

error

a FsError

  

fs_parse_error ()

gboolean
fs_parse_error (GObject *object,
                GstMessage *message,
                FsError *error,
                const gchar **error_msg);

Parses a "farstream-farstream" message and checks if it matches the object parameters.

Parameters

object

a GObject to match against the message

  

message

a GstMessage to parse

  

error

Returns the FsError error number in the message if not NULL.

[out]

error_msg

Returns the error message if not NULL.

[out][transfer none]

Returns

TRUE if the message matches the object and is valid.

Types and Values

struct FsConference

struct FsConference;

The FsConference structure, all the members are private

enum FsError

This is the enum of error numbers that will come either on the "error" signal, from the Gst Bus or for error in the FS_ERROR domain in GErrors

Members

FS_ERROR_CONSTRUCTION

Error constructing some of the sub-elements, this probably denotes an error in the installation of the gstreamer elements. It is a fatal error.

  

FS_ERROR_INTERNAL

An internal error happened in Farstream, it may be in an inconsistent state. The object from which this error comes should be discarded.

  

FS_ERROR_INVALID_ARGUMENTS

Invalid arguments to the function, this is a programming error and should not be reported to the user

  

FS_ERROR_NETWORK

A network related error, this should probably be reported to the user.

  

FS_ERROR_NOT_IMPLEMENTED

The optional functionality is not implemented by this plugin.

  

FS_ERROR_NEGOTIATION_FAILED

The codec negotiation has failed, this means that there are no common codecs between the local and remote codecs.

  

FS_ERROR_UNKNOWN_CODEC

Data is received on an unknown codec, this most likely denotes an error on the remote side, the buffers will be ignored. It can safely be ignored in most cases (but may result in a call with no media received).

  

FS_ERROR_NO_CODECS

There are no codecs detected for that media type.

  

FS_ERROR_NO_CODECS_LEFT

All of the codecs have been disabled by the codec preferences, one should try less strict codec preferences.

  

FS_ERROR_CONNECTION_FAILED

Could not connect to the to remote party.

  

FS_ERROR_DISPOSED

The object has been disposed.

  

FS_ERROR_ALREADY_EXISTS

The object already exists
