gstcontroller.c.types

A value mapping object that attaches multiple control sources to a guint gobject properties representing a color. A control value of 0.0 will turn the color component off and a value of 1.0 will be the color level.

structGstControlPoint

An internal structure for value+time and various temporary values used for interpolation. This "inherits" from GstTimedValue.

Fields

GstClockTime timestamptimestamp of the value change

double valuethe new value

CacheType cache

structGstDirectControlBinding

A value mapping object that attaches control sources to gobject properties. It will map the control values directly to the target property range. If a non-absolute direct control binding is used, the value range [0.0 ... 1.0] is mapped to full target property range, and all values outside the range will be clipped. An absolute control binding will not do any value transformations.

structGstDirectControlBindingClass

The class structure of #GstDirectControlBinding.

void *[4] GstReserved

structGstInterpolationControlSource

#GstInterpolationControlSource is a #GstControlSource, that interpolates values between user-given control points. It supports several interpolation modes and property types.

To use #GstInterpolationControlSource get a new instance by calling [gstcontroller.interpolation_control_source.InterpolationControlSource.new_], bind it to a #GParamSpec and set some control points by calling [gstcontroller.timed_value_control_source.TimedValueControlSource.set].

All functions are MT-safe.

structGstLFOControlSource

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

To use #GstLFOControlSource get a new instance by calling [gstcontroller.lfocontrol_source.LFOControlSource.new_], bind it to a #GParamSpec and set the relevant properties.

All functions are MT-safe.

structGstTimedValueControlSource

Base class for #GstControlSource that use time-stamped values.

When overriding bind, chain up first to give this bind implementation a chance to setup things.

structGstTriggerControlSource

#GstTriggerControlSource is a #GstControlSource, that returns values from user-given control points. It allows for a tolerance on the time-stamps.

To use #GstTriggerControlSource get a new instance by calling [gstcontroller.trigger_control_source.TriggerControlSource.new_], bind it to a #GParamSpec and set some control points by calling [gstcontroller.timed_value_control_source.TimedValueControlSource.set].

All functions are MT-safe.
