GstInterpolationControlSource

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 gst_interpolation_control_source_new, bind it to a GParamSpec and set some control points by calling gst_timed_value_control_source_set.

All functions are MT-safe.

Enumerations

GstInterpolationMode

The various interpolation modes available.

Members
GST_INTERPOLATION_MODE_NONE (0) –

steps-like interpolation, default

GST_INTERPOLATION_MODE_LINEAR (1) –

linear interpolation

GST_INTERPOLATION_MODE_CUBIC (2) –

cubic interpolation (natural), may overshoot the min or max values set by the control point, but is more 'curvy'

GST_INTERPOLATION_MODE_CUBIC_MONOTONIC (3) –

monotonic cubic interpolation, will not produce any values outside of the min-max range set by the control points (Since: 1.8)
