Implemented Interfaces

BtSinkMachine implements GstChildProxy and BtPersistence.

Includes

#include <libbtcore/core.h>

Description

Sinks are machines that do playback or recording of the song. The sink-machine utilizes the BtSinkBin to transparently switch elements between record (encoding) and playback.

Functions

bt_sink_machine_new ()

BtSinkMachine *
bt_sink_machine_new (const BtSong * const song,
                     const gchar * const id,
                     GError **err);

Create a new instance. The machine is automatically added to the setup from the given song object. You don't need to add the machine with

bt_setup_add_machine(setup,BT_MACHINE(machine));.

The element used for this machine is BtSinkBin which is configured according to the use-case (playback, recording). The playback device is taken from the BtSettings.

Parameters

song

the song the new instance belongs to

 

id

the id, we can use to lookup the machine

 

err

inform about failed instance creation

 

Returns

the new instance or NULL in case of an error

Types and Values

struct BtSinkMachine

struct BtSinkMachine;

Sub-class of a BtMachine that implements a signal output (a machine with inputs only).
