static Glib::RefPtr<Gst::MessageStreamStatus> Gst::MessageStreamStatus::create	(	const Glib::RefPtr< Gst::Object >&	src,
		Gst::StreamStatusType	type,
		const Glib::RefPtr< Gst::Element >&	owner
	)

static

Create a new stream status message.

This message is posted when a streaming thread is created/destroyed or when the state changed.

Parameters

src	The object originating the message.
type	The stream status type.
owner	The owner element of src.

Returns: The new stream status message. MT safe.

Glib::RefPtr<Gst::Object> Gst::MessageStreamStatus::get_object ( ) const

Extracts the object managing the streaming thread from message.

Returns: The object that manages the streaming thread. The actual object is usually a Gst::Task but other types can be added in the future. The object remains valid as long as the message is valid.

void Gst::MessageStreamStatus::parse	(	Gst::StreamStatusType&	type,
		Glib::RefPtr< Gst::Element >&	owner
	)		const

Extracts the stream status type and owner of the Gst::Message.

The returned owner remains valid for as long as the reference to the message is valid.

MT safe.

Parameters

type	A reference to hold the status type.
owner	A reference to hold the owner Gst::Element.

Since 0.10.24.

Gst::StreamStatusType Gst::MessageStreamStatus::parse ( ) const

Extracts the stream status type.

MT safe.

Returns: The stream status type.

Since 0.10.24.

Glib::RefPtr<Gst::Element> Gst::MessageStreamStatus::parse_owner ( ) const

Extracts the owner of the Gst::Message.

The returned owner remains valid for as long as the reference to the message is valid.

MT safe.

Returns: The owner Gst::Element.

Since 0.10.24.

void Gst::MessageStreamStatus::set_object ( const Glib::RefPtr< Gst::Object >& object )

Configures the object handling the streaming thread.

This is usually a Gst::Task object but other objects might be added in the future.

Parameters

object The object controlling the streaming.

Since 0.10.24.
