Struct LFOControl
Source pub struct LFOControlSource { /* private fields */ }Expand description
LFOControlSource is a gst::ControlSource, that provides several periodic
waveforms as control values.
To use LFOControlSource get a new instance by calling
new(), bind it to a GParamSpec and set the relevant
properties.
All functions are MT-safe.
§Properties
§amplitude
Specifies the amplitude for the waveform of this LFOControlSource.
Readable | Writeable
§frequency
Specifies the frequency that should be used for the waveform
of this LFOControlSource. It should be large enough
so that the period is longer than one nanosecond.
Readable | Writeable
§offset
Specifies the value offset for the waveform of this LFOControlSource.
Readable | Writeable
§timeshift
Specifies the timeshift to the right that should be used for the waveform
of this LFOControlSource in nanoseconds.
To get a n nanosecond shift to the left use “(GST_SECOND / frequency) - n”.
Readable | Writeable
§waveform
Specifies the waveform that should be used for this LFOControlSource.

Object
§name
Readable | Writeable | Construct
§parent
The parent of the object. Please note, that when changing the ‘parent’
property, we don’t emit GObject::notify and deep-notify
signals due to locking issues. In some cases one can use
GstBin::element-added or GstBin::element-removed signals on the parent to
achieve a similar effect.

§Implements
LFOControlSourceExt, gst::prelude::ControlSourceExt, gst::prelude::ObjectExt
