Detailed Description

Enumeration Type Documentation

◆ Emotion_Suspend

enum Emotion_Suspend

Used for emotion pipeline resource management.

See also: emotion_object_suspend_set(); emotion_object_suspend_get()

Enumerator
EMOTION_WAKEUP	pipeline is up and running
EMOTION_SLEEP	turn off hardware resource usage like overlay
EMOTION_DEEP_SLEEP	destroy the pipeline, but keep full resolution pixels output around
EMOTION_HIBERNATE	destroy the pipeline, and keep half resolution or object resolution if lower

Function Documentation

◆ emotion_object_priority_set()

void emotion_object_priority_set	(	Evas_Object *	obj,
		Eina_Bool	priority
	)

Raise priority of an object so it will have a priviledged access to hardware resources.

Parameters

obj	The object which the query is being ran on.
priority	EINA_TRUE means give me a priority access to the hardware resources.

Hardware have a few dedicated hardware pipeline that process the video at no cost for the CPU. Especially on SoC, you mostly have one (on mobile phone SoC) or two (on Set Top Box SoC) when Picture in Picture is needed. And most application just have a few video stream that really deserve high frame rate, high quality output. That's why this call is for.

Please note that if Emotion can't acquire a priviledged hardware resource, it will fallback to the no-priority path. This work on the first asking first get basis system.

◆ emotion_object_priority_get()

Eina_Bool emotion_object_priority_get ( const Evas_Object * obj )

Get the actual priority of an object.

Parameters

obj	The object which the query is being ran on.

Returns: EINA_TRUE if the object has a priority access to the hardware.

This actually return the priority status of an object. If it failed to have a priviledged access to the hardware, it will return EINA_FALSE.

References EINA_FALSE.

◆ emotion_object_suspend_set()

void emotion_object_suspend_set	(	Evas_Object *	obj,
		Emotion_Suspend	state
	)

Change the state of an object pipeline.

Parameters

obj	The object which the query is being ran on.
state	The new state for the object.

Changing the state of a pipeline should help preserve the battery of an embedded device. But it will only work sanely if the pipeline is not playing at the time you change its state. Depending on the engine all state may be not implemented.
