LFOControlSource

GstLFOControlSource is a ControlSource, that provides several periodic waveforms as control values.

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

All functions are MT-safe.

Constructors

class LFOControlSource

classmethod new() → ControlSource: This returns a new, unbound GstLFOControlSource.

class LFOControlSource

props.amplitude: float: Specifies the amplitude for the waveform of this GstLFOControlSource.

props.frequency: float: Specifies the frequency that should be used for the waveform of this GstLFOControlSource. It should be large enough so that the period is longer than one nanosecond.

props.offset: float: Specifies the value offset for the waveform of this GstLFOControlSource.

props.timeshift: int

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

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

props.waveform: LFOWaveform: Specifies the waveform that should be used for this GstLFOControlSource.
