Member Function Documentation

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
srcThe object originating the message.
formatThe format of the position being played.
positionThe position of the segment being played.
Returns
The new segment start message. MT safe.
void Gst::MessageSegmentStart::parse ( Format format,
gint64 &  position 
) const

Extracts the position and format from the segment start message.

MT safe.

Parameters
formatResult location for the format.
positionResult location for the position.
gint64 Gst::MessageSegmentStart::parse ( ) const

Extracts and returns the position from the segment start message.

MT safe.

Returns
The position.
Format Gst::MessageSegmentStart::parse_format ( ) const

Extracts and returns the format from the segment start message.

MT safe.

Returns
The format.
