      <doc xml:space="preserve">The Assets in the GStreamer Editing Services represent the resources
that can be used. You can create assets for any type that implements the #GESExtractable
interface, for example #GESClips, #GESFormatter, and #GESTrackElement do implement it.
This means that assets will represent for example a #GESUriClips, #GESBaseEffect etc,
and then you can extract objects of those types with the appropriate parameters from the asset
using the #ges_asset_extract method:

|[
GESAsset *effect_asset;
GESEffect *effect;

// You create an asset for an effect
effect_asset = ges_asset_request (GES_TYPE_EFFECT, "agingtv", NULL);

// And now you can extract an instance of GESEffect from that asset
effect = GES_EFFECT (ges_asset_extract (effect_asset));

]|

In that example, the advantages of having a #GESAsset are that you can know what effects
you are working with and let your user know about the avalaible ones, you can add metadata
to the #GESAsset through the #GESMetaContainer interface and you have a model for your
custom effects. Note that #GESAsset management is making easier thanks to the #GESProject class.

Each asset is represented by a pair of @extractable_type and @id (string). Actually the @extractable_type
is the type that implements the #GESExtractable interface, that means that for example for a #GESUriClip,
the type that implements the #GESExtractable interface is #GESClip.
The identifier represents different things depending on the @extractable_type and you should check
the documentation of each type to know what the ID of #GESAsset actually represents for that type. By default,
we only have one #GESAsset per type, and the @id is the name of the type, but this behaviour is overriden
to be more useful. For example, for GESTransitionClips, the ID is the vtype of the transition
you will extract from it (ie crossfade, box-wipe-rc etc..) For #GESEffect the ID is the
@bin-description property of the extracted objects (ie the gst-launch style description of the bin that
will be used).

Each and every #GESAsset is cached into GES, and you can query those with the #ges_list_assets function.
Also the system will automatically register #GESAssets for #GESFormatters and #GESTransitionClips
and standard effects (actually not implemented yet) and you can simply query those calling:
|[
   GList *formatter_assets, *tmp;

   //  List all  the transitions
   formatter_assets = ges_list_assets (GES_TYPE_FORMATTER);

   // Print some infos about the formatter GESAsset
   for (tmp = formatter_assets; tmp; tmp = tmp-&gt;next) {
     g_print ("Name of the formatter: %s, file extension it produces: %s",
       ges_meta_container_get_string (GES_META_CONTAINER (tmp-&gt;data), GES_META_FORMATTER_NAME),
       ges_meta_container_get_string (GES_META_CONTAINER (tmp-&gt;data), GES_META_FORMATTER_EXTENSION));
   }

   g_list_free (transition_assets);

]|

You can request the creation of #GESAssets using either ges_asset_request() or
ges_asset_request_async(). All the #GESAssets are cached and thus any asset that has already
been created can be requested again without overhead.</doc>

clips at the end, splitted at the time specified by @position, as a position
in the timeline (not in the clip to be split). For example, if
ges_clip_split is called on a 4-second clip playing from 0:01.00 until
0:05.00, with a split position of 0:02.00, this will result in one clip of 1
second and one clip of 3 seconds, not in two clips of 2 seconds.

The newly created clip will be added to the same layer as @clip is in. This
implies that @clip must be in a #GESLayer for the operation to be possible.

This method supports clips playing at a different tempo than one second per
second. For example, splitting a clip with a #GESEffect 'pitch tempo=1.5'
four seconds after it starts, will set the inpoint of the new clip to six
seconds after that of the clip to split. For this, the rate-changing
property must be registered using @ges_effect_class_register_rate_property;
for the 'pitch' plugin, this is already done.</doc>

When changes happen in a timeline, they are not
directly executed in the non-linear engine. Call this method once you are
done with a set of changes and want it to be executed.

The #GESTimeline::commited signal will be emitted when the (possibly updated)
#GstPipeline is ready to output data again, except if the state of the
timeline was #GST_STATE_READY or #GST_STATE_NULL.

Note that all the pending changes will automatically be executed when the
timeline goes from #GST_STATE_READY to #GST_STATE_PAUSED, which usually is
triggered by corresponding state changes in a containing #GESPipeline.

You should not try to change the state of the timeline, seek it or add
tracks to it during a commit operation, that is between a call to this
function and after receiving the #GESTimeline::commited signal.

See #ges_timeline_commit_sync if you don't want to bother with waiting
for the signal.</doc>

## Children Properties

You can use the following children properties through the
#ges_track_element_set_child_property and alike set of methods:
&lt;informaltable frame="none"&gt;
&lt;tgroup cols="3"&gt;
&lt;colspec colname="properties_type" colwidth="150px"/&gt;
&lt;colspec colname="properties_name" colwidth="200px"/&gt;
&lt;colspec colname="properties_flags" colwidth="400px"/&gt;
&lt;tbody&gt;
&lt;row&gt;
 &lt;entry role="property_type"&gt;&lt;link linkend="guint"&gt;&lt;type&gt;guint&lt;/type&gt;&lt;/link&gt;&lt;/entry&gt;
 &lt;entry role="property_name"&gt;&lt;link linkend="GESTileSource--background"&gt;background&lt;/link&gt;&lt;/entry&gt;
 &lt;entry&gt;The color of the background&lt;/entry&gt;
&lt;/row&gt;
&lt;row&gt;
 &lt;entry role="property_type"&gt;&lt;link linkend="guint"&gt;&lt;type&gt;guint&lt;/type&gt;&lt;/link&gt;&lt;/entry&gt;
 &lt;entry role="property_name"&gt;&lt;link linkend="GESTileSource--color"&gt;color&lt;/link&gt;&lt;/entry&gt;
 &lt;entry&gt;The color of the text&lt;/entry&gt;
&lt;/row&gt;
&lt;row&gt;
  &lt;entry role="property_type"&gt;&lt;link linkend="gchar"&gt;&lt;type&gt;gchar&lt;/type&gt;&lt;/link&gt;&lt;/entry&gt;

The shape of the video transition depends on the value of the "vtype"

supported.
