                                   (GESTrackElementAsset *asset);

Get the GESAssetTrackType the GESTrackElement extracted from `self` should get into

#### Parameters

asset | A GESAssetObject |

#### Returns

a GESTrackType

### ges_track_element_asset_set_track_type ()

    void
    ges_track_element_asset_set_track_type
                                   (GESTrackElementAsset *asset,
                                    GESTrackType type);

Set the GESAssetTrackType the GESTrackElement extracted from `self` should get into

#### Parameters

### ges_track_element_add_children_props ()

    void
    ges_track_element_add_children_props (GESTrackElement *self,
                                          GstElement *element,
                                          const gchar **wanted_categories,
                                          const gchar **blacklist,
                                          const gchar **whitelist);

Looks for the properties defines with the various parametters and add them to the hashtable of children properties.

To be used by subclasses only

#### Parameters

self | The GESTrackElement to set chidlren props on |
element | The GstElement to retrieve properties from |
wanted_categories | An array of categories of GstElement to take into account (as defined in the factory meta "klass" field). | [array zero-terminated=1][transfer none][allow-none]
blacklist | A blacklist of elements factory names to not take into account. | [array zero-terminated=1][transfer none][allow-none]
whitelist | A list of propery names to add as children properties. | [array zero-terminated=1][transfer none][allow-none]
