Member Function Documentation

create()

static Glib::RefPtr<Gst::MessageSegmentStart> Gst::MessageSegmentStart::create ( const Glib::RefPtr< Gst::Object >&  src, Format  format, gint64  position  )

static

Create a new segment message.

This message is posted by elements that start playback of a segment as a result of a segment seek. This message is not received by the application but is used for maintenance reasons in container elements.

Parameters

src	The object originating the message.
format	The format of the position being played.
position	The position of the segment being played.

Returns

The new segment start message.

MT safe.

parse()

void Gst::MessageSegmentStart::parse	(	Format&	format,
		gint64 &	position
	)		const

Extracts the position and format from the segment start message.

MT safe.

Parameters

format	Result location for the format.
position	Result location for the position.

parse_format()

Format Gst::MessageSegmentStart::parse_format

(

)

const

Extracts and returns the format from the segment start message.

MT safe.

Returns

The format.

parse_position()

gint64 Gst::MessageSegmentStart::parse_position

(

)

const

Extracts and returns the position from the segment start message.

MT safe.

Returns

The position.
