Description
Packit f546b1 
GstInterpolationControlSource is a GstControlSource, that interpolates values between user-given
Packit f546b1 
control points. It supports several interpolation modes and property types.
Packit f546b1 
To use GstInterpolationControlSource get a new instance by calling
Packit f546b1 
gst_interpolation_control_source_new(), bind it to a GParamSpec and set some
Packit f546b1 
control points by calling gst_timed_value_control_source_set().
Packit f546b1 
All functions are MT-safe.
