seq_sequence_lookup_effects_by_seq()

blender::Span< Sequence * > seq_sequence_lookup_effects_by_seq	(	const Scene *	scene,
		const Sequence *	key )

Find effect strips, that use strip seq as one of inputs. If lookup hash doesn't exist, it will be created. If hash is tagged as invalid, it will be rebuilt.

Parameters

scene	scene that owns lookup hash
key	pointer to Sequence inside of meta strip

Returns

collection of effect strips

seq_sequence_lookup_meta_by_seq()

Sequence * seq_sequence_lookup_meta_by_seq	(	const Scene *	scene,
		const Sequence *	key )

Find meta strip, that contains strip key. If lookup hash doesn't exist, it will be created. If hash is tagged as invalid, it will be rebuilt.

Parameters

scene	scene that owns lookup hash
key	pointer to Sequence inside of meta strip

Returns

pointer to meta strip

SEQ_sequence_lookup_owner_by_channel()

Sequence * SEQ_sequence_lookup_owner_by_channel	(	const Scene *	scene,
