	abort_state () : none Abort the state change of the element. Abort the state change of the element. This function is used by elements that do asynchronous state changes and find out something is wrong. This function should be called with the STATE_LOCK held. MT safe. Returns: none	Gst.Element
	add_pad (Pad *pad) : Boolean Adds a pad (link point) to element. Adds a pad (link point) to element. pad's parent will be set to element; see gst_object_set_parent() for refcounting information. Pads are not automatically activated so elements should perform the needed steps to activate the pad in case this pad is added in the PAUSED or PLAYING state. See gst_pad_set_active() for more information about activating pads. The pad and the element should be unlocked when calling this function. This function will emit the GstElement::pad-added signal on the element. a pad with the same name already existed or the pad already had another parent. MT safe. Parameters: Gst.Pad pad* Required (not null) Returns: Boolean	Gst.Element

	get_start_time () : Number Returns the start time of the element. Returns the start time of the element. The start time is the running time of the clock when this element was last put to PAUSED.

	get_state (Object *out_values, State pending, Number timeout) : Gst.StateChangeReturn Gets the state of the element. Gets the state of the element. For elements that performed an ASYNC state change, as reported by gst_element_set_state(), this function will block up to the specified timeout value for the state change to complete. If the element completes the state change or goes into an error, this function returns immediately with a return value of GST_STATE_CHANGE_SUCCESS* or GST_STATE_CHANGE_FAILURE respectively. For elements that did not return GST_STATE_CHANGE_ASYNC, this function returns the current and pending state immediately. This function returns GST_STATE_CHANGE_NO_PREROLL if the element successfully changed its state but is not able to provide data yet. This mostly happens for live sources that only produce data in GST_STATE_PLAYING. While the state change return is equivalent to GST_STATE_CHANGE_SUCCESS, it is returned to the application to signal that some sink elements might not be able to complete their state change because an element is not producing data to complete the preroll. When setting the element to playing, the preroll will complete and playback will start. MT safe.

An ASYNC_START message is posted with indication to distribute a new base_time to the element when new_base_time* is TRUE. If the element was PLAYING, it will go to PAUSED. The element will be restored to its PLAYING state by the parent pipeline when it prerolls again. This is mostly used for elements that lost their preroll buffer in the GST_STATE_PAUSED or GST_STATE_PLAYING state after a flush, they will go to their pending state again when a new preroll buffer is queued.

This function emits the GstElement::no-more-pads signal. MT safe. Returns: none	Gst.Element
	post_message (Message *message) : Boolean Post a message on the element's GstBus. Post a message on the element's GstBus.

Parameters: Gst.Object parent Required (not null) Returns: Boolean	Gst.Object
	set_start_time (Number *time) : none Set the start time of an element. Set the start time of an element. The start time of the element is the running time of the element when it last went to the PAUSED state. In READY or after a flushing seek, it is set to 0. Toplevel elements like GstPipeline* will manage the start_time and base_time on its children. Setting the start_time to GST_CLOCK_TIME_NONE on such a toplevel element will disable the distribution of the base_time to the children and can be useful if the application manages the base_time itself, for example if you want to synchronize capture from multiple pipelines, and you can also ensure that the pipelines have the same clock. MT safe. Parameters: Number time Required (not null) Returns: none	Gst.Element

This function can return GST_STATE_CHANGE_ASYNC, in which case the element will perform the remainder of the state change asynchronously in another thread. An application can use gst_element_get_state() to wait for the completion of the state change or it can wait for a state change message on the bus.
