Class Details¶

class GstController.LFOControlSource(**kwargs)¶

Bases:: Gst.ControlSource
Abstract:: No
Structure:: GstController.LFOControlSourceClass

GstController.LFOControlSource is a Gst.ControlSource, that provides several periodic waveforms as control values.

To use GstController.LFOControlSource get a new instance by calling GstController.LFOControlSource.new(), bind it to a GObject.ParamSpec and set the relevant properties.

All functions are MT-safe.

classmethod new()¶

Returns:: a new, unbound GstController.LFOControlSource.
Return type:: Gst.ControlSource

This returns a new, unbound GstController.LFOControlSource.

Property Details¶

GstController.LFOControlSource.props.amplitude¶

Name:: amplitude
Type:: float
Default Value:: 1.0
Flags:: READABLE, WRITABLE

Specifies the amplitude for the waveform of this GstController.LFOControlSource.

GstController.LFOControlSource.props.frequency¶

Name:: frequency
Type:: float
Default Value:: 1.0
Flags:: READABLE, WRITABLE

Specifies the frequency that should be used for the waveform of this GstController.LFOControlSource. It should be large enough so that the period is longer than one nanosecond.

GstController.LFOControlSource.props.offset¶

Name:: offset
Type:: float
Default Value:: 1.0
Flags:: READABLE, WRITABLE

Specifies the value offset for the waveform of this GstController.LFOControlSource.

GstController.LFOControlSource.props.timeshift¶

Name:: timeshift
Type:: int
Default Value:: 0
Flags:: READABLE, WRITABLE

Specifies the timeshift to the right that should be used for the waveform of this GstController.LFOControlSource in nanoseconds.

To get a n nanosecond shift to the left use “(Gst.SECOND / frequency) - n”.

GstController.LFOControlSource.props.waveform¶

Name:: waveform
Type:: GstController.LFOWaveform
Default Value:: GstController.LFOWaveform.SINE
Flags:: READABLE, WRITABLE

Specifies the waveform that should be used for this GstController.LFOControlSource.
