BaseEffect, Effect

Required methods

This is supported on crate feature v1_18 only.

Get whether the effect is considered a time effect or not. An effect with registered time properties or set translation functions is considered a time effect.

Returns

true if self is considered a time effect.

This is supported on crate feature v1_18 only.

Register a child property of the effect as a property that, when set, can change the timing of its input data. The child property should be specified as in ges_timeline_element_lookup_child().

You should also set the corresponding time translation using ges_base_effect_set_time_translation_funcs().

Note that self must not be part of a clip, nor can it have property::TrackElement::has-internal-source set to true.

child_property_name

The name of the child property to register as a time property

Returns

true if the child property was found and newly registered.
