      <doc xml:space="preserve" filename="../subprojects/gst-editing-services/ges/ges-asset.c">A #GESAsset in the GStreamer Editing Services represents a resources
that can be used. In particular, any class that implements the
#GESExtractable interface may have some associated assets with a
corresponding #GESAsset:extractable-type, from which its objects can be
extracted using ges_asset_extract(). Some examples would be
#GESClip, #GESFormatter and #GESTrackElement.

All assets that are created within GES are stored in a cache; one per
each #GESAsset:id and #GESAsset:extractable-type pair. These assets can
be fetched, and initialized if they do not yet exist in the cache,
using ges_asset_request().

``` c
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));

```

The advantage of using assets, rather than simply creating the object
directly, is that the currently loaded resources can be listed with
ges_list_assets() and displayed to an end user. For example, to show
which media files have been loaded, and a standard list of effects. In
fact, the GES library already creates assets for #GESTransitionClip and
#GESFormatter, which you can use to list all the available transition
types and supported formats.

The other advantage is that #GESAsset implements #GESMetaContainer, so
metadata can be set on the asset, with some subclasses automatically
creating this metadata on initiation.

For example, to display information about the supported formats, you
could do the following:
|[
   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) {
     gst_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);

## ID

Each asset is uniquely defined in the cache by its
#GESAsset:extractable-type and #GESAsset:id. Depending on the
#GESAsset:extractable-type, the #GESAsset:id can be used to parametrise
the creation of the object upon extraction. By default, a class that
implements #GESExtractable will only have a single associated asset,
with an #GESAsset:id set to the type name of its objects. However, this
is overwritten by some implementations, which allow a class to have
multiple associated assets. For example, for #GESTransitionClip the
#GESAsset:id will be a nickname of the #GESTransitionClip:vtype. You
should check the documentation for each extractable type to see if they
differ from the default.

Moreover, each #GESAsset:extractable-type may also associate itself
with a specific asset subclass. In such cases, when their asset is
requested, an asset of this subclass will be returned instead.

## Managing

You can use a #GESProject to easily manage the assets of a
#GESTimeline.

## Proxies

Some assets can (temporarily) act as the #GESAsset:proxy of another
asset. When the original asset is requested from the cache, the proxy
will be returned in its place. This can be useful if, say, you want
to substitute a #GESUriClipAsset corresponding to a high resolution
media file with the asset of a lower resolution stand in.

An asset may even have several proxies, the first of which will act as
its default and be returned on requests, but the others will be ordered
to take its place once it is removed. You can add a proxy to an asset,
or set its default, using ges_asset_set_proxy(), and you can remove
them with ges_asset_unproxy().</doc>

exists in the cache (it has been previously created in GES), then a
reference to the existing asset is returned. Otherwise, a newly created
asset is returned, and also added to the cache.

If the requested asset has been loaded with an error, then @error is
set, if given, and %NULL will be returned instead.

Note that the given @id may not be exactly the #GESAsset:id that is
set on the returned asset. For instance, it may be adjusted into a
standard format. Or, if a #GESExtractable type does not have its
extraction parametrised, as is the case by default, then the given @id
may be ignored entirely and the #GESAsset:id set to some standard, in
which case a %NULL @id can be given.

Similarly, the given @extractable_type may not be exactly the
#GESAsset:extractable-type that is set on the returned asset. Instead,
the actual extractable type may correspond to a subclass of the given
@extractable_type, depending on the given @id.

Moreover, depending on the given @extractable_type, the returned asset
may belong to a subclass of #GESAsset.

Finally, if the requested asset has a #GESAsset:proxy, then the proxy
that is found at the end of the chain of proxies is returned (a proxy's
proxy will take its place, and so on, unless it has no proxy).

Some asset subclasses only support asynchronous construction of its
assets, such as #GESUriClip. For such assets this method will fail, and
you should use ges_asset_request_async() instead. In the case of
#GESUriClip, you can use ges_uri_clip_asset_request_sync() if you only
want to wait for the request to finish.</doc>

Note that the source object passed to the callback will be the
#GESAsset corresponding to the request, but it may not have loaded
correctly and therefore can not be used as is. Instead,
ges_asset_request_finish() should be used to fetch a usable asset, or
indicate that an error occurred in the asset's creation.

Note that the callback will be called in the #GMainLoop running under
the same #GMainContext that ges_init() was called in. So, if you wish
the callback to be invoked outside the default #GMainContext, you can
call g_main_context_push_thread_default() in a new thread before
calling ges_init().

Example of an asynchronous asset request:
``` c
// The request callback
static void
asset_loaded_cb (GESAsset * source, GAsyncResult * res, gpointer user_data)
{
  GESAsset *asset;
  GError *error = NULL;

  asset = ges_asset_request_finish (res, &amp;error);
  if (asset) {

      <doc xml:space="preserve" filename="../subprojects/gst-editing-services/ges/ges-base-effect.c">A #GESBaseEffect is some operation that applies an effect to the data
it receives.

## Time Effects

Some operations will change the timing of the stream data they receive
in some way. In particular, the #GstElement that they wrap could alter
the times of the segment they receive in a #GST_EVENT_SEGMENT event,
or the times of a seek they receive in a #GST_EVENT_SEEK event. Such
operations would be considered time effects since they translate the
times they receive on their source to different times at their sink,
and vis versa. This introduces two sets of time coordinates for the
event: (internal) sink coordinates and (internal) source coordinates,
where segment times are translated from the sink coordinates to the
source coordinates, and seek times are translated from the source
coordinates to the sink coordinates.

If you use such an effect in GES, you will need to inform GES of the
properties that control the timing with
ges_base_effect_register_time_property(), and the effect's timing
behaviour using ges_base_effect_set_time_translation_funcs().

Note that a time effect should not have its
#GESTrackElement:has-internal-source set to %TRUE.

In addition, note that GES only *fully* supports time effects whose
mapping from the source to sink coordinates (those applied to seeks)
obeys:

+ Maps the time `0` to `0`. So initial time-shifting effects are
  excluded.
+ Is monotonically increasing. So reversing effects, and effects that
  jump backwards in the stream are excluded.
+ Can handle a reasonable #GstClockTime, relative to the project. So
  this would exclude a time effect with an extremely large speed-up
  that would cause the converted #GstClockTime seeks to overflow.
+ Is 'continuously reversible'. This essentially means that for every
  time in the sink coordinates, we can, to 'good enough' accuracy,
  calculate the corresponding time in the source coordinates. Moreover,
  this should correspond to how segment times are translated from
  sink to source.
+ Only depends on the registered time properties, rather than the
  state of the #GstElement or the data it receives. This would exclude,
  say, an effect that would speedup if there is more red in the image
  it receives.

Note that a constant-rate-change effect that is not extremely fast or
slow would satisfy these conditions. For such effects, you may wish to
use ges_effect_class_register_rate_property().</doc>

      <doc xml:space="preserve" filename="../subprojects/gst-editing-services/ges/ges-clip.c">#GESClip-s are the core objects of a #GESLayer. Each clip may exist in
a single layer but may control several #GESTrackElement-s that span
several #GESTrack-s. A clip will ensure that all its children share the
same #GESTimelineElement:start and #GESTimelineElement:duration in
their tracks, which will match the #GESTimelineElement:start and
#GESTimelineElement:duration of the clip itself. Therefore, changing
the timing of the clip will change the timing of the children, and a
change in the timing of a child will change the timing of the clip and
subsequently all its siblings. As such, a clip can be treated as a
singular object in its layer.

For most uses of a #GESTimeline, it is often sufficient to only
interact with #GESClip-s directly, which will take care of creating and
organising the elements of the timeline's tracks.

## Core Children

In more detail, clips will usually have some *core* #GESTrackElement
children, which are created by the clip when it is added to a layer in
a timeline. The type and form of these core children will depend on the
clip's subclass. You can use ges_track_element_is_core() to determine
whether a track element is considered such a core track element. Note,
if a core track element is part of a clip, it will always be treated as
a core *child* of the clip. You can connect to the
#GESContainer::child-added signal to be notified of their creation.

When a child is added to a clip, the timeline will select its tracks
using #GESTimeline::select-tracks-for-object. Note that it may be the
case that the child will still have no set #GESTrackElement:track
after this process. For example, if the timeline does not have a track
of the corresponding #GESTrack:track-type. A clip can safely contain
such children, which may have their track set later, although they will
play no functioning role in the timeline in the meantime.

If a clip may create track elements with various
#GESTrackElement:track-type(s), such as a #GESUriClip, but you only
want it to create a subset of these types, you should set the
#GESClip:supported-formats of the clip to the subset of types. This
should be done *before* adding the clip to a layer.

If a clip will produce several core elements of the same
#GESTrackElement:track-type, you should connect to the timeline's
#GESTimeline::select-tracks-for-object signal to coordinate which
tracks each element should land in. Note, no two core children within a
clip can share the same #GESTrack, so you should not select the same
track for two separate core children. Provided you stick to this rule,
it is still safe to select several tracks for the same core child, the
core child will be copied into the additional tracks. You can manually
add the child to more tracks later using ges_clip_add_child_to_track().
If you do not wish to use a core child, you can always select no track.

The #GESTimelineElement:in-point of the clip will control the
#GESTimelineElement:in-point of its core children to be the same
value if their #GESTrackElement:has-internal-source is set to %TRUE.

The #GESTimelineElement:max-duration of the clip is the minimum
#GESTimelineElement:max-duration of its core children. If you set its
value to anything other than its current value, this will also set the
#GESTimelineElement:max-duration of all its core children to the same
value if their #GESTrackElement:has-internal-source is set to %TRUE.
As a special case, whilst a clip does not yet have any core children,
its #GESTimelineElement:max-duration may be set to indicate what its
value will be once they are created.

## Effects

Some subclasses (#GESSourceClip and #GESBaseEffectClip) may also allow
their objects to have additional non-core #GESBaseEffect-s elements as
children. These are additional effects that are applied to the output
data of the core elements. They can be added to the clip using
ges_clip_add_top_effect(), which will take care of adding the effect to
the timeline's tracks. The new effect will be placed between the clip's
core track elements and its other effects. As such, the newly added
effect will be applied to any source data **before** the other existing
effects. You can change the ordering of effects using
ges_clip_set_top_effect_index().

Tracks are selected for top effects in the same way as core children.
If you add a top effect to a clip before it is part of a timeline, and
later add the clip to a timeline, the track selection for the top
effects will occur just after the track selection for the core
children. If you add a top effect to a clip that is already part of a
timeline, the track selection will occur immediately. Since a top
effect must be applied on top of a core child, if you use
#GESTimeline::select-tracks-for-object, you should ensure that the
added effects are destined for a #GESTrack that already contains a core
child.

In addition, if the core child in the track is not
#GESTrackElement:active, then neither can any of its effects be
#GESTrackElement:active. Therefore, if a core child is made in-active,
all of the additional effects in the same track will also become
in-active. Similarly, if an effect is set to be active, then the core
child will also become active, but other effects will be left alone.
Finally, if an active effect is added to the track of an in-active core
child, it will become in-active as well. Note, in contrast, setting a
core child to be active, or an effect to be in-active will *not* change
the other children in the same track.

### Time Effects

Some effects also change the timing of their data (see #GESBaseEffect
for what counts as a time effect). Note that a #GESBaseEffectClip will
refuse time effects, but a #GESSource will allow them.

When added to a clip, time effects may adjust the timing of other
children in the same track. Similarly, when changing the order of
effects, making them (in)-active, setting their time property values
or removing time effects. These can cause the #GESClip:duration-limit
to change in value. However, if such an operation would ever cause the
#GESTimelineElement:duration to shrink such that a clip's #GESSource is
totally overlapped in the timeline, the operation would be prevented.
Note that the same can happen when adding non-time effects with a
finite #GESTimelineElement:max-duration.

Therefore, when working with time effects, you should -- more so than
usual -- not assume that setting the properties of the clip's children
will succeed. In particular, you should use
ges_timeline_element_set_child_property_full() when setting the time
properties.

If you wish to preserve the *internal* duration of a source in a clip
during these time effect operations, you can do something like the
following.

```c
void
do_time_effect_change (GESClip * clip)
{
  GList *tmp, *children;
  GESTrackElement *source;
  GstClockTime source_outpoint;
  GstClockTime new_end;
  GError *error = NULL;

  // choose some active source in a track to preserve the internal
  // duration of
  source = ges_clip_get_track_element (clip, NULL, GES_TYPE_SOURCE);

  // note its current internal end time
  source_outpoint = ges_clip_get_internal_time_from_timeline_time (
        clip, source, GES_TIMELINE_ELEMENT_END (clip), NULL);

  // handle invalid out-point

  // stop the children's control sources from clamping when their
  // out-point changes with a change in the time effects
  children = ges_container_get_children (GES_CONTAINER (clip), FALSE);

  for (tmp = children; tmp; tmp = tmp-&gt;next)
    ges_track_element_set_auto_clamp_control_sources (tmp-&gt;data, FALSE);

  // add time effect, or set their children properties, or move them around
  ...
  // user can make sure that if a time effect changes one source, we should
  // also change the time effect for another source. E.g. if
  // "GstVideorate::rate" is set to 2.0, we also set "GstPitch::rate" to
  // 2.0

  // Note the duration of the clip may have already changed if the
  // duration-limit of the clip dropped below its current value

  new_end = ges_clip_get_timeline_time_from_internal_time (
        clip, source, source_outpoint, &amp;error);
  // handle error

  if (!ges_timeline_elemnet_edit_full (GES_TIMELINE_ELEMENT (clip),
        -1, GES_EDIT_MODE_TRIM, GES_EDGE_END, new_end, &amp;error))
    // handle error

  for (tmp = children; tmp; tmp = tmp-&gt;next)
    ges_track_element_set_auto_clamp_control_sources (tmp-&gt;data, TRUE);

  g_list_free_full (children, gst_object_unref);
  gst_object_unref (source);
}

This will take any time effects placed on the clip into account (see
#GESBaseEffect for what time effects are supported, and how to
declare them in GES).

When @timeline_time is above the #GESTimelineElement:start of @clip,
this will return the internal time at which the content that appears at
@timeline_time in the output of the timeline is created in @child. For
example, if @timeline_time corresponds to the current seek position,
this would let you know which part of a media file is being read.

This will be done assuming the clip has an indefinite end, so the
internal time may be beyond the current out-point of the child, or even
its #GESTimelineElement:max-duration.

If, instead, @timeline_time is below the current
#GESTimelineElement:start of @clip, this will return what you would
need to set the #GESTimelineElement:in-point of @child to if you set
the #GESTimelineElement:start of @clip to @timeline_time and wanted

#GESTimelineElement:start of @clip at the same timeline position. If
this would be negative, the conversion fails. This is useful for
determining what #GESTimelineElement:in-point would result from a

Note that whilst a clip has no time effects, this second return is
equivalent to finding the internal time at which the content that
appears at @timeline_time in the timeline can be found in @child if it
had indefinite extent in both directions. However, with non-linear time
effects this second return will be more distinct.

In either case, the returned time would be appropriate to use for the

must already have a #GESClip:layer.

The original clip's #GESTimelineElement:duration is reduced such that
its end point matches the split position. Then a new clip is created in
the same layer, whose #GESTimelineElement:start matches the split
position and #GESTimelineElement:duration will be set such that its end
point matches the old end point of the original clip. Thus, the two
clips together will occupy the same positions in the timeline as the
original clip did.

The children of the new clip will be new copies of the original clip's
children, so it will share the same sources and use the same
operations.

The new clip will also have its #GESTimelineElement:in-point set so
that any internal data will appear in the timeline at the same time.
Thus, when the timeline is played, the playback of data should
appear the same. This may be complicated by any additional
#GESEffect-s that have been placed on the original clip that depend on
the playback time or change the data consumption rate of sources. This
method will attempt to translate these effects such that the playback
appears the same. In such complex situations, you may get a better
result if you place the clip in a separate sub #GESProject, which only
contains this clip (and its effects), and in the original layer
create two neighbouring #GESUriClip-s that reference this sub-project,
but at a different #GESTimelineElement:in-point.</doc>

      <doc xml:space="preserve" filename="../subprojects/gst-editing-services/ges/ges-enums.h">When a single timeline element is edited within its timeline at some
position, using ges_timeline_element_edit(), depending on the edit
mode, its #GESTimelineElement:start, #GESTimelineElement:duration or
#GESTimelineElement:in-point will be adjusted accordingly. In addition,
any clips may change #GESClip:layer.

Each edit can be broken down into a combination of three basic edits:

+ MOVE: This moves the start of the element to the edit position.
+ START-TRIM: This cuts or grows the start of the element, whilst
  maintaining the time at which its internal content appears in the
  timeline data output. If the element is made shorter, the data that
  appeared at the edit position will still appear in the timeline at
  the same time. If the element is made longer, the data that appeared
  at the previous start of the element will still appear in the
  timeline at the same time.
+ END-TRIM: Similar to START-TRIM, but the end of the element is cut or
  grown.

In particular, when editing a #GESClip:

+ MOVE: This will set the #GESTimelineElement:start of the clip to the
  edit position.
+ START-TRIM: This will set the #GESTimelineElement:start of the clip
  to the edit position. To keep the end time the same, the
  #GESTimelineElement:duration of the clip will be adjusted in the
  opposite direction. In addition, the #GESTimelineElement:in-point of
  the clip will be shifted such that the content that appeared at the
  new or previous start time, whichever is latest, still appears at the
  same timeline time. For example, if a frame appeared at the start of
  the clip, and the start of the clip is reduced, the in-point of the
  clip will also reduce such that the frame will appear later within
  the clip, but at the same timeline position.
+ END-TRIM: This will set the #GESTimelineElement:duration of the clip
  such that its end time will match the edit position.

When editing a #GESGroup:

+ MOVE: This will set the #GESGroup:start of the clip to the edit
  position by shifting all of its children by the same amount. So each
  child will maintain their relative positions.
+ START-TRIM: If the group is made shorter, this will START-TRIM any
  clips under the group that start after the edit position to the same
  edit position. If the group is made longer, this will START-TRIM any
  clip under the group whose start matches the start of the group to
  the same edit position.
+ END-TRIM: If the group is made shorter, this will END-TRIM any clips
  under the group that end after the edit position to the same edit
  position. If the group is made longer, this will END-TRIM any clip
  under the group whose end matches the end of the group to the same
  edit position.

When editing a #GESTrackElement, if it has a #GESClip parent, this
will be edited instead. Otherwise it is edited in the same way as a
#GESClip.

The layer priority of a #GESGroup is the lowest layer priority of any
#GESClip underneath it. When a group is edited to a new layer
priority, it will shift all clips underneath it by the same amount,
such that their relative layers stay the same.

If the #GESTimeline has a #GESTimeline:snapping-distance, then snapping
may occur for some of the edges of the **main** edited element:

+ MOVE: The start or end edge of *any* #GESSource under the element may
  be snapped.
+ START-TRIM: The start edge of a #GESSource whose start edge touches
  the start edge of the element may snap.
+ END-TRIM: The end edge of a #GESSource whose end edge touches the end
  edge of the element may snap.

These edges may snap with either the start or end edge of *any* other
#GESSource in the timeline that is not also being moved by the element,
including those in different layers, if they are within the
#GESTimeline:snapping-distance. During an edit, only up to one snap can
occur. This will shift the edit position such that the snapped edges
will touch once the edit has completed.

Note that snapping can cause an edit to fail where it would have
otherwise succeeded because it may push the edit position such that the
edit would result in an unsupported timeline configuration. Similarly,
snapping can cause an edit to succeed where it would have otherwise
failed.

For example, in #GES_EDIT_MODE_RIPPLE acting on #GES_EDGE_NONE, the
main element is the MOVED toplevel of the edited element. Any source
under the main MOVED toplevel may have its start or end edge snapped.
Note, these sources cannot snap with each other. The edit may also
push other elements, but any sources under these elements cannot snap,
nor can they be snapped with. If a snap does occur, the MOVE of the
toplevel *and* all other elements pushed by the ripple will be shifted
by the same amount such that the snapped edges will touch.

You can also find more explanation about the behaviour of those modes at:
[trim, ripple and roll](http://pitivi.org/manual/trimming.html)
and [clip management](http://pitivi.org/manual/usingclips.html).</doc>

have is that effects element should have a single [sinkpad](GST_PAD_SINK)
(which will be requested if necessary) and a single [srcpad](GST_PAD_SRC).

Note that `gesaudiomixer` and `gescompositor` can be used as effects even
though they can have several sinkpads.

## GES specific effects:

* **`gesvideoscale`**: GES implements a specific scaling bin that allows
  specifying where scaling will happen inside the chain of effects. By
  default scaling can happen either in the source (if the source doesn't have
  a specific size, like `videotestsrc` or [mixing](ges_track_set_mixing) has
  been disabled) or in the mixing element otherwise, when adding that element
  as an effect, GES guarantees that the scaling will happen in it. This can
  be useful for example if you want to crop the video before scaling or apply
  rounding corners to the video after scaling, etc...

&gt; Note: GES always adds converters (`audioconvert ! audioresample !
&gt; audioconvert` for audio effects and `videoconvert` for video effects) to
&gt; make it simpler for end users.</doc>

The property type must be float or double, and must be a factor of the
rate, i.e. a value of 2.0 must mean that the media plays twice as fast.
Several properties may be registered for a single element type,
provided they all contribute to the rate as independent factors. For
example, this is true for the "GstPitch::rate" and "GstPitch::tempo"
properties. These are already registered by default in GES, along with
#videorate:rate for #videorate and #scaletempo:rate for #scaletempo.

If such a rate property becomes a child property of a #GESEffect upon
its creation (the element is part of its #GESEffect:bin-description),
it will be automatically registered as a time property (see
ges_base_effect_register_time_property()) and will have its time
translation functions set (see
ges_base_effect_set_time_translation_funcs()) to use the overall rate
of the rate properties. Note that if an effect contains a rate
property as well as a non-rate time property, you should ensure to set
the time translation functions to some other methods using
ges_base_effect_set_time_translation_funcs().

Note, you can obtain a reference to the GESEffectClass using

```
  GES_EFFECT_CLASS (g_type_class_ref (GES_TYPE_EFFECT));

      <doc xml:space="preserve" filename="../subprojects/gst-editing-services/ges/ges-extractable.c">A #GObject that implements the #GESExtractable interface can be
extracted from a #GESAsset using ges_asset_extract().

Each extractable type will have its own way of interpreting the
#GESAsset:id of an asset (or, if it is associated with a specific
subclass of #GESAsset, the asset subclass may handle the
interpretation of the #GESAsset:id). By default, the requested asset
#GESAsset:id will be ignored by a #GESExtractable and will be set to
the type name of the extractable instead. Also by default, when the
requested asset is extracted, the returned object will simply be a
newly created default object of that extractable type. You should check
the documentation for each extractable type to see if they differ from
the default.

After the object is extracted, it will have a reference to the asset it
came from, which you can retrieve using ges_extractable_get_asset().</doc>

      <doc xml:space="preserve" filename="../subprojects/gst-editing-services/ges/ges-group.c">A #GESGroup controls one or more #GESContainer-s (usually #GESClip-s,
but it can also control other #GESGroup-s). Its children must share
the same #GESTimeline, but can otherwise lie in separate #GESLayer-s
and have different timings.

To initialise a group, you may want to use ges_container_group(),
and similarly use ges_container_ungroup() to dispose of it.

A group will maintain the relative #GESTimelineElement:start times of
its children, as well as their relative layer #GESLayer:priority.
Therefore, if one of its children has its #GESTimelineElement:start
set, all other children will have their #GESTimelineElement:start
shifted by the same amount. Similarly, if one of its children moves to
a new layer, the other children will also change layers to maintain the
difference in their layer priorities. For example, if a child moves
from a layer with #GESLayer:priority 1 to a layer with priority 3, then
another child that was in a layer with priority 0 will move to the
layer with priority 2.

The #GESGroup:start of a group refers to the earliest start
time of its children. If the group's #GESGroup:start is set, all the
children will be shifted equally such that the earliest start time
will match the set value. The #GESGroup:duration of a group is the
difference between the earliest start time and latest end time of its
children. If the group's #GESGroup:duration is increased, the children
whose end time matches the end of the group will be extended
accordingly. If it is decreased, then any child whose end time exceeds
the new end time will also have their duration decreased accordingly.

A group may span several layers, but for methods such as
ges_timeline_element_get_layer_priority() and
ges_timeline_element_edit() a group is considered to have a layer
priority that is the highest #GESLayer:priority (numerically, the
smallest) of all the layers it spans.</doc>

      <doc xml:space="preserve" filename="../subprojects/gst-editing-services/ges/ges-layer.c">#GESLayer-s are responsible for collecting and ordering #GESClip-s.

A layer within a timeline will have an associated priority,
corresponding to their index within the timeline. A layer with the
index/priority 0 will have the highest priority and the layer with the
largest index will have the lowest priority (the order of priorities,
in this sense, is the _reverse_ of the numerical ordering of the
indices). ges_timeline_move_layer() should be used if you wish to
change how layers are prioritised in a timeline.

Layers with higher priorities will have their content priorities
over content from lower priority layers, similar to how layers are
used in image editing. For example, if two separate layers both
display video content, then the layer with the higher priority will
have its images shown first. The other layer will only have its image
shown if the higher priority layer has no content at the given
playtime, or is transparent in some way. Audio content in separate
layers will simply play in addition.</doc>

it, that is data that is unimportant to its function within GES, but
may hold some useful information. In particular,
ges_meta_container_set_meta() can be used to store any #GValue under
any generic field (specified by a string key). The same method can also
be used to remove the field by passing %NULL. A number of convenience
methods are also provided to make it easier to set common value types.
The metadata can then be read with ges_meta_container_get_meta() and
similar convenience methods.

## Registered Fields

By default, any #GValue can be set for a metadata field. However, you
can register some fields as static, that is they only allow values of a
specific type to be set under them, using
ges_meta_container_register_meta() or
ges_meta_container_register_static_meta(). The set #GESMetaFlag will
determine whether the value can be changed, but even if it can be
changed, it must be changed to a value of the same type.

Internally, some GES objects will be initialized with static metadata
fields. These will correspond to some standard keys, such as
#GES_META_VOLUME.</doc>

Unlike ges_meta_container_register_meta(), no (initial) value is set
for this field, which means you can use this method to reserve the
space to be _optionally_ set later.

Note that if a value has already been set for the field being
registered, then its type must match the registering type, and its
value will be left in place. If the field has no set value, then
you will likely want to include #GES_META_WRITABLE in @flags to allow

      <doc xml:space="preserve" filename="../subprojects/gst-editing-services/ges/ges-project.c">The #GESProject is used to control a set of #GESAsset and is a
#GESAsset with `GES_TYPE_TIMELINE` as @extractable_type itself. That
means that you can extract #GESTimeline from a project as followed:

```c
GESProject *project;
GESTimeline *timeline;

project = ges_project_new ("file:///path/to/a/valid/project/uri");

// Here you can connect to the various signal to get more infos about
// what is happening and recover from errors if possible
...

timeline = ges_asset_extract (GES_ASSET (project));
```

The #GESProject class offers a higher level API to handle #GESAsset-s.
It lets you request new asset, and it informs you about new assets through
a set of signals. Also it handles problem such as missing files/missing
#GstElement and lets you try to recover from those.

## Subprojects

In order to add a subproject, the only thing to do is to add the subproject
to the main project:

``` c
ges_project_add_asset (project, GES_ASSET (subproject));
```
then the subproject will be serialized in the project files. To use
the subproject in a timeline, you should use a #GESUriClip with the
same subproject URI.

When loading a project with subproject, subprojects URIs will be temporary
writable local files. If you want to edit the subproject timeline,
you should retrieve the subproject from the parent project asset list and
extract the timeline with ges_asset_extract() and save it at
the same temporary location.</doc>

## Asset

The default asset ID is GESTestClip, but the framerate and video
size can be overridden using an ID of the form:

```
framerate=60/1, width=1920, height=1080, max-duration=5.0
```
Note: `max-duration` can be provided in seconds as float, or as GstClockTime
as guint64 or gint.</doc>

      <doc xml:space="preserve" filename="../subprojects/gst-editing-services/ges/ges-timeline.c">#GESTimeline is the central object for any multimedia timeline.

A timeline is composed of a set of #GESTrack-s and a set of
#GESLayer-s, which are added to the timeline using
ges_timeline_add_track() and ges_timeline_append_layer(), respectively.

The contained tracks define the supported types of the timeline
and provide the media output. Essentially, each track provides an
additional source #GstPad.

Most usage of a timeline will likely only need a single #GESAudioTrack
and/or a single #GESVideoTrack. You can create such a timeline with
ges_timeline_new_audio_video(). After this, you are unlikely to need to
work with the tracks directly.

A timeline's layers contain #GESClip-s, which in turn control the
creation of #GESTrackElement-s, which are added to the timeline's
tracks. See #GESTimeline::select-tracks-for-object if you wish to have
more control over which track a clip's elements are added to.

The layers are ordered, with higher priority layers having their
content prioritised in the tracks. This ordering can be changed using
ges_timeline_move_layer().

## Editing

See #GESTimelineElement for the various ways the elements of a timeline
can be edited.

If you change the timing or ordering of a timeline's
#GESTimelineElement-s, then these changes will not actually be taken
into account in the output of the timeline's tracks until the
ges_timeline_commit() method is called. This allows you to move its
elements around, say, in response to an end user's mouse dragging, with
little expense before finalising their effect on the produced data.

## Overlaps and Auto-Transitions

There are certain restrictions placed on how #GESSource-s may overlap
in a #GESTrack that belongs to a timeline. These will be enforced by
GES, so the user will not need to keep track of them, but they should
be aware that certain edits will be refused as a result if the overlap
rules would be broken.

Consider two #GESSource-s, `A` and `B`, with start times `startA` and
`startB`, and end times `endA` and `endB`, respectively. The start
time refers to their #GESTimelineElement:start, and the end time is
their #GESTimelineElement:start + #GESTimelineElement:duration. These
two sources *overlap* if:

+ they share the same #GESTrackElement:track (non %NULL), which belongs
  to the timeline;
+ they share the same #GES_TIMELINE_ELEMENT_LAYER_PRIORITY; and
+ `startA &lt; endB` and `startB &lt; endA `.

Note that when `startA = endB` or `startB = endA` then the two sources
will *touch* at their edges, but are not considered overlapping.

If, in addition, `startA &lt; startB &lt; endA`, then we can say that the
end of `A` overlaps the start of `B`.

If, instead, `startA &lt;= startB` and `endA &gt;= endB`, then we can say
that `A` fully overlaps `B`.

The overlap rules for a timeline are that:

1. One source cannot fully overlap another source.
2. A source can only overlap the end of up to one other source at its
   start.
3. A source can only overlap the start of up to one other source at its
   end.

The last two rules combined essentially mean that at any given timeline
position, only up to two #GESSource-s may overlap at that position. So
triple or more overlaps are not allowed.

If you switch on #GESTimeline:auto-transition, then at any moment when
the end of one source (the first source) overlaps the start of another
(the second source), a #GESTransitionClip will be automatically created
for the pair in the same layer and it will cover their overlap. If the
two elements are edited in a way such that the end of the first source
no longer overlaps the start of the second, the transition will be
automatically removed from the timeline. However, if the two sources
still overlap at the same edges after the edit, then the same
transition object will be kept, but with its timing and layer adjusted
accordingly.

NOTE: if you know what you are doing and want to be in full control of the
timeline layout, you can disable the edit APIs with
#ges_timeline_disable_edit_apis.

## Saving

To save/load a timeline, you can use the ges_timeline_load_from_uri()
and ges_timeline_save_to_uri() methods that use the default format.

## Playing

A timeline is a #GstBin with a source #GstPad for each of its
tracks, which you can fetch with ges_timeline_get_pad_for_track(). You
will likely want to link these to some compatible sink #GstElement-s to
be able to play or capture the content of the timeline.

You can use a #GESPipeline to easily preview/play the timeline's
content, or render it to a file.</doc>

When changes happen in a timeline, they are not immediately executed
internally, in a way that effects the output data of the timeline. You
should call this method when you are done with a set of changes and you
want them to be executed.

Any pending changes will be executed in the backend. The
#GESTimeline::commited signal will be emitted once this has completed.
You should not try to change the state of the timeline, seek it or add
tracks to it before receiving this signal. You can use
ges_timeline_commit_sync() if you do not want to perform other tasks in
the mean time.

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

        <doc xml:space="preserve" filename="../subprojects/gst-editing-services/ges/ges-timeline.c">This will be emitted whenever the timeline needs to determine which
tracks a clip's children should be added to. The track element will
be added to each of the tracks given in the return. If a track
element is selected to go into multiple tracks, it will be copied
into the additional tracks, under the same clip. Note that the copy
will *not* keep its properties or state in sync with the original.

Connect to this signal once if you wish to control which element
should be added to which track. Doing so will overwrite the default
behaviour, which adds @track_element to all tracks whose
#GESTrack:track-type includes the @track_element's
#GESTrackElement:track-type.

Note that under the default track selection, if a clip would produce
multiple core children of the same #GESTrackType, it will choose
one of the core children arbitrarily to place in the corresponding
tracks, with a warning for the other core children that are not
placed in the track. For example, this would happen for a #GESUriClip
that points to a file that contains multiple audio streams. If you
wish to choose the stream, you could connect to this signal, and use,
say, ges_uri_source_asset_get_stream_info() to choose which core
source to add.

When a clip is first added to a timeline, its core elements will
be created for the current tracks in the timeline if they have not
already been created. Then this will be emitted for each of these
core children to select which tracks, if any, they should be added
to. It will then be called for any non-core children in the clip.

In addition, if a new track element is ever added to a clip in a
timeline (and it is not already part of a track) this will be emitted
to select which tracks the element should be added to.

Finally, as a special case, if a track is added to the timeline
*after* it already contains clips, then it will request the creation
of the clips' core elements of the corresponding type, if they have
not already been created, and this signal will be emitted for each of
these newly created elements. In addition, this will also be released
for all other track elements in the timeline's clips that have not
yet been assigned a track. However, in this final case, the timeline
will only check whether the newly added track appears in the track
list. If it does appear, the track element will be added to the newly
added track. All other tracks in the returned track list are ignored.

In this latter case, track elements that are already part of a track
will not be asked if they want to be copied into the new track. If
you wish to do this, you can use ges_clip_add_child_to_track().

Note that the returned #GPtrArray should own a new reference to each
of its contained #GESTrack. The timeline will set the #GDestroyNotify
free function on the #GPtrArray to dereference the elements.</doc>

      <doc xml:space="preserve" filename="../subprojects/gst-editing-services/ges/ges-timeline-element.c">A #GESTimelineElement will have some temporal extent in its
corresponding #GESTimelineElement:timeline, controlled by its
#GESTimelineElement:start and #GESTimelineElement:duration. This
determines when its content will be displayed, or its effect applied,
in the timeline. Several objects may overlap within a given
#GESTimeline, in which case their #GESTimelineElement:priority is used
to determine their ordering in the timeline. Priority is mostly handled
internally by #GESLayer-s and #GESClip-s.

A timeline element can have a #GESTimelineElement:parent,
such as a #GESClip, which is responsible for controlling its timing.

## Editing

Elements can be moved around in their #GESTimelineElement:timeline by
setting their #GESTimelineElement:start and
#GESTimelineElement:duration using ges_timeline_element_set_start()
and ges_timeline_element_set_duration(). Additionally, which parts of
the underlying content are played in the timeline can be adjusted by
setting the #GESTimelineElement:in-point using
ges_timeline_element_set_inpoint(). The library also provides
ges_timeline_element_edit(), with various #GESEditMode-s, which can
adjust these properties in a convenient way, as well as introduce
similar changes in neighbouring or later elements in the timeline.

However, a timeline may refuse a change in these properties if they
would place the timeline in an unsupported configuration. See
#GESTimeline for its overlap rules.

Additionally, an edit may be refused if it would place one of the
timing properties out of bounds (such as a negative time value for
#GESTimelineElement:start, or having insufficient internal
content to last for the desired #GESTimelineElement:duration).

## Time Coordinates

There are three main sets of time coordinates to consider when using
timeline elements:

+ Timeline coordinates: these are the time coordinates used in the
  output of the timeline in its #GESTrack-s. Each track share the same
  coordinates, so there is only one set of coordinates for the
  timeline. These extend indefinitely from 0. The times used for
  editing (including setting #GESTimelineElement:start and
  #GESTimelineElement:duration) use these coordinates, since these
  define when an element is present and for how long the element lasts
  for in the timeline.
+ Internal source coordinates: these are the time coordinates used
  internally at the element's output. This is only really defined for
  #GESTrackElement-s, where it refers to time coordinates used at the
  final source pad of the wrapped #GstElement-s. However, these
  coordinates may also be used in a #GESClip in reference to its
  children. In particular, these are the coordinates used for
  #GESTimelineElement:in-point and #GESTimelineElement:max-duration.
+ Internal sink coordinates: these are the time coordinates used
  internally at the element's input. A #GESSource has no input, so
  these would be undefined. Otherwise, for most #GESTrackElement-s
  these will be the same set of coordinates as the internal source
  coordinates because the element does not change the timing
  internally. Only #GESBaseEffect can support elements where these
  are different. See #GESBaseEffect for more information.

You can determine the timeline time for a given internal source time
in a #GESTrack in a #GESClip using
ges_clip_get_timeline_time_from_internal_time(), and vice versa using
ges_clip_get_internal_time_from_timeline_time(), for the purposes of
editing and setting timings properties.

## Children Properties

If a timeline element owns another #GstObject and wishes to expose
some of its properties, it can do so by registering the property as one
of the timeline element's children properties using
ges_timeline_element_add_child_property(). The registered property of
the child can then be read and set using the
ges_timeline_element_get_child_property() and
ges_timeline_element_set_child_property() methods, respectively. Some
sub-classed objects will be created with pre-registered children
properties; for example, to expose part of an underlying #GstElement
that is used internally. The registered properties can be listed with
ges_timeline_element_list_children_properties().</doc>

After calling this function @element should not be used. In particular,

      <doc xml:space="preserve" filename="../subprojects/gst-editing-services/ges/ges-track.c">A #GESTrack acts an output source for a #GESTimeline. Each one
essentially provides an additional #GstPad for the timeline, with
#GESTrack:restriction-caps capabilities. Internally, a track
wraps an #nlecomposition filtered by a #capsfilter.

A track will contain a number of #GESTrackElement-s, and its role is
to select and activate these elements according to their timings when
the timeline in played. For example, a track would activate a
#GESSource when its #GESTimelineElement:start is reached by outputting
its data for its #GESTimelineElement:duration. Similarly, a
#GESOperation would be activated by applying its effect to the source
data, starting from its #GESTimelineElement:start time and lasting for
its #GESTimelineElement:duration.

For most users, it will usually be sufficient to add newly created
tracks to a timeline, but never directly add an element to a track.
Whenever a #GESClip is added to a timeline, the clip adds its
elements to the timeline's tracks and assumes responsibility for
updating them.</doc>

If @type is #GES_TRACK_TYPE_AUDIO, and @caps is a subset of

      <doc xml:space="preserve" filename="../subprojects/gst-editing-services/ges/ges-track-element.c">A #GESTrackElement is a #GESTimelineElement that specifically belongs
to a single #GESTrack of its #GESTimelineElement:timeline. Its
#GESTimelineElement:start and #GESTimelineElement:duration specify its
temporal extent in the track. Specifically, a track element wraps some
nleobject, such as an #nlesource or #nleoperation, which can be
retrieved with ges_track_element_get_nleobject(), and its
#GESTimelineElement:start, #GESTimelineElement:duration,
#GESTimelineElement:in-point, #GESTimelineElement:priority and
#GESTrackElement:active properties expose the corresponding nleobject
properties. When a track element is added to a track, its nleobject is
added to the corresponding #nlecomposition that the track wraps.

Most users will not have to work directly with track elements since a
#GESClip will automatically create track elements for its timeline's
tracks and take responsibility for updating them. The only track
elements that are not automatically created by clips, but a user is
likely to want to create, are #GESEffect-s.

## Control Bindings for Children Properties

You can set up control bindings for a track element child property
using ges_track_element_set_control_source(). A
#GstTimedValueControlSource should specify the timed values using the
internal source coordinates (see #GESTimelineElement). By default,
these will be updated to lie between the #GESTimelineElement:in-point
and out-point of the element. This can be switched off by setting
#GESTrackElement:auto-clamp-control-sources to %FALSE.</doc>

        <doc xml:space="preserve" filename="../subprojects/gst-editing-services/ges/ges-track-element.c">This property is used to determine whether the 'internal time'
properties of the element have any meaning. In particular, unless
this is set to %TRUE, the #GESTimelineElement:in-point and
#GESTimelineElement:max-duration can not be set to any value other
than the default 0 and #GST_CLOCK_TIME_NONE, respectively.

If an element has some *internal* *timed* source #GstElement that it
reads stream data from as part of its function in a #GESTrack, then
you'll likely want to set this to %TRUE to allow the
#GESTimelineElement:in-point and #GESTimelineElement:max-duration to
be set.

The default value is determined by the #GESTrackElementClass
@default_has_internal_source class property. For most
#GESSourceClass-es, this will be %TRUE, with the exception of those
that have a potentially *static* source, such as #GESImageSourceClass
and #GESTitleSourceClass. Otherwise, this will usually be %FALSE.

For most #GESOperation-s you will likely want to leave this set to
%FALSE. The exception may be for an operation that reads some stream
data from some private internal source as part of manipulating the
input data from the usual linked upstream #GESTrackElement.

For example, you may want to set this to %TRUE for a
#GES_TRACK_TYPE_VIDEO operation that wraps a #textoverlay that reads
from a subtitle file and places its text on top of the received video
data. The #GESTimelineElement:in-point of the element would be used
to shift the initial seek time on the #textoverlay away from 0, and
the #GESTimelineElement:max-duration could be set to reflect the
time at which the subtitle file runs out of data.

Note that GES can not support track elements that have both internal
content and manipulate the timing of their data streams (time
effects).</doc>

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

supported.

set to "video/x-raw" with the following properties:

- width: 1280

These fields are needed for negotiation purposes, but you can change
their values if you wish. It is advised that you do so using
ges_track_update_restriction_caps() with new values for the fields you
wish to change, and any additional fields you may want to add. Unlike
using ges_track_set_restriction_caps(), this will ensure that these
default fields will at least have some value set.</doc>
