Original commit message from CVS: Reviewed by: Stefan Kost <ensonic@users.sf.net> * libs/gst/controller/Makefile.am: * libs/gst/controller/gstcontroller.c: (gst_controlled_property_add_interpolation_control_source), (gst_controlled_property_new), (gst_controlled_property_free), (gst_controller_find_controlled_property), (gst_controller_new_valist), (gst_controller_new_list), (gst_controller_new), (gst_controller_remove_properties_valist), (gst_controller_remove_properties_list), (gst_controller_remove_properties), (gst_controller_set_property_disabled), (gst_controller_set_disabled), (gst_controller_set_control_source), (gst_controller_get_control_source), (gst_controller_get), (gst_controller_sync_values), (gst_controller_get_value_array), (_gst_controller_dispose), (gst_controller_get_type), (gst_controlled_property_set_interpolation_mode), (gst_controller_set), (gst_controller_set_from_list), (gst_controller_unset), (gst_controller_unset_all), (gst_controller_get_all), (gst_controller_set_interpolation_mode): * libs/gst/controller/gstcontroller.h: * libs/gst/controller/gstcontrollerprivate.h: * libs/gst/controller/gstcontrolsource.c: (gst_control_source_class_init), (gst_control_source_init), (gst_control_source_get_value), (gst_control_source_get_value_array), (gst_control_source_bind): * libs/gst/controller/gstcontrolsource.h: * libs/gst/controller/gsthelper.c: (gst_object_set_control_source), (gst_object_get_control_source): * libs/gst/controller/gstinterpolation.c: (gst_interpolation_control_source_find_control_point_node), (gst_interpolation_control_source_get_first_value), (_interpolate_none_get), (interpolate_none_get), (interpolate_none_get_boolean_value_array), (interpolate_none_get_enum_value_array), (interpolate_none_get_string_value_array), (_interpolate_trigger_get), (interpolate_trigger_get), (interpolate_trigger_get_boolean_value_array), (interpolate_trigger_get_enum_value_array), (interpolate_trigger_get_string_value_array): * libs/gst/controller/gstinterpolationcontrolsource.c: (gst_control_point_free), (gst_interpolation_control_source_reset), (gst_interpolation_control_source_new), (gst_interpolation_control_source_set_interpolation_mode), (gst_interpolation_control_source_bind), (gst_control_point_compare), (gst_control_point_find), (gst_interpolation_control_source_set_internal), (gst_interpolation_control_source_set), (gst_interpolation_control_source_set_from_list), (gst_interpolation_control_source_unset), (gst_interpolation_control_source_unset_all), (gst_interpolation_control_source_get_all), (gst_interpolation_control_source_get_count), (gst_interpolation_control_source_init), (gst_interpolation_control_source_finalize), (gst_interpolation_control_source_dispose), (gst_interpolation_control_source_class_init): * libs/gst/controller/gstinterpolationcontrolsource.h: * libs/gst/controller/gstinterpolationcontrolsourceprivate.h: API: Refactor GstController into the core controller which can take a GstControlSource for providing actual values for timestamps. Implement a interpolation control source and use this for backward compatibility, deprecate a bunch of functions that are now handled by GstControlSource or GstInterpolationControlSource. Make it possible to disable the controller completely or only for specific properties. Fixes #450711. * docs/libs/gstreamer-libs-docs.sgml: * docs/libs/gstreamer-libs-sections.txt: * docs/libs/gstreamer-libs.types: Add new functions and classes to the docs. * tests/check/libs/controller.c: (GST_START_TEST), (gst_controller_suite): * tests/examples/controller/audio-example.c: (main): Port unit test and example to the new API and add some new unit tests.
