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.
struct GstInterpolationControlSource;
The instance structure of GstControlSource.
typedef enum {
GST_INTERPOLATION_MODE_NONE,
GST_INTERPOLATION_MODE_LINEAR,
GST_INTERPOLATION_MODE_CUBIC,
GST_INTERPOLATION_MODE_CUBIC_MONOTONIC,
} GstInterpolationMode;
The various interpolation modes available.
| 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) |
GstControlSource * gst_interpolation_control_source_new
(void);
