Functions

GESExtractableCheckId ()

gchar *
(*GESExtractableCheckId) (GType type,
                          const gchar *id,
                          GError **error);

Parameters

type	The GType to check `id` for:
id	The id to check
error	An error that can be set if needed

Returns

The ID to use for the asset or NULL if id is not valid

ges_extractable_get_asset ()

GESAsset *
ges_extractable_get_asset (GESExtractable *self);

Method for getting an asset from a GESExtractable

Parameters

self

The GESExtractable from which to retrieve a GESAsset

Returns

The GESAsset or NULL if none has been set.

[transfer none][nullable]

ges_extractable_set_asset ()

gboolean
ges_extractable_set_asset (GESExtractable *self,
                           GESAsset *asset);

Method to set the asset which instantiated the specified object

Return: TRUE if asset could be set FALSE otherwize

Parameters

self	Target object
asset	The GESAsset to set.	[transfer none]

ges_extractable_get_id ()

gchar *
