Description
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.
Functions
gst_interpolation_control_source_new ()
GstControlSource *
gst_interpolation_control_source_new (void);
This returns a new, unbound GstInterpolationControlSource.
Types and Values
struct GstInterpolationControlSource
struct GstInterpolationControlSource;
The instance structure of GstControlSource.
enum GstInterpolationMode
The various interpolation modes available.
Members
|
steps-like interpolation, default |
||
|
linear interpolation |
||
|
cubic interpolation (natural), may overshoot the min or max values set by the control point, but is more 'curvy' |
||
|
monotonic cubic interpolation, will not produce any values outside of the min-max range set by the control points (Since 1.8) |
Property Details
The “mode” property
