Tizen Native API  5.5
Screen Mirroring

The Screen Mirroring API provides functions for screen mirroring as sink.

Required Header

#include <scmirroring_sink.h>

Overview

The Screen Mirroring API allows you to implement screen mirroring application as sink. It gives the ability to connect to and disconnect from a screen mirroring source, and start, pause, and resume the screen mirroring sink, set the resolution or display, register state change callback function.

State Diagram

The following diagram shows the life cycle and states of the screen mirroring sink.

State Transitions

FUNCTION PRE-STATE POST-STATE SYNC TYPE
scmirroring_sink_create() NONE NULL SYNC
scmirroring_sink_destroy() NULL NONE SYNC
scmirroring_sink_prepare() NULL PREPARED SYNC
scmirroring_sink_unprepare() PREPARED, DISCONNECTED NULL SYNC
scmirroring_sink_connect() PREPARED CONNECTED ASYNC
scmirroring_sink_start() CONNECTED PLAYING ASYNC
scmirroring_sink_disconnect() CONNECTED, PAUSED or PLAYING DISCONNECTED SYNC
scmirroring_sink_pause() PLAYING PAUSED ASYNC
scmirroring_sink_resume() PAUSED PLAYING ASYNC

State Dependent Function Calls

The following table shows state-dependent function calls. It is forbidden to call the functions listed below in wrong state. Violation of this rule may result in unpredictable behavior.

scmirroring_sink_get_negotiated_audio_bitwidth() CONNECTED/ PLAYING/ PAUSED This function must be called after scmirroring_sink_connect().

Asynchronous Operations

All functions that change the state are synchronous except scmirroring_sink_connect(), scmirroring_sink_start(), scmirroring_sink_pause(), and scmirroring_sink_resume(). Thus the result is passed to the application via the callback mechanism.

Callback(Event) Operations

REGISTER UNREGISTER CALLBACK DESCRIPTION
scmirroring_sink_set_state_changed_cb() scmirroring_sink_unset_state_changed_cb() scmirroring_state_cb() This callback is called for state and error of screen mirroring.
