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->next) { + gst_print ("Name of the formatter: %s, file extension it produces: %s", + ges_meta_container_get_string ( + GES_META_CONTAINER (tmp->data), GES_META_FORMATTER_NAME), + ges_meta_container_get_string ( + GES_META_CONTAINER (tmp->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.

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.

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->next) + ges_track_element_set_auto_clamp_control_source (tmp->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.

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> + <member name="edit_normal" value="0" c:identifier="GES_EDIT_MODE_NORMAL" glib:nick="edit_normal"> + <doc xml:space="preserve" filename="../subprojects/gst-editing-services/ges/ges-enums.h">The element is edited the normal way (default). + If acting on the element as a whole (#GES_EDGE_NONE), this will MOVE + the element by MOVING its toplevel.

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 < endB` and `startB < 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 < startB < endA`, then we can say that the +end of `A` overlaps the start of `B`. + +If, instead, `startA <= startB` and `endA >= 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> + <source-position filename="../subprojects/gst-editing-services/ges/ges-timeline.h"/> + <implements name="Extractable"/> + <implements

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.

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> + <source-position filename="../subprojects/gst-editing-services/ges/ges-timeline-element.h"/> + <implements name="Extractable"/> + <implements name="MetaContainer"/> + <virtual-method name="deep_copy"> + <source-position filename="../subprojects/gst-editing-services/ges/ges-timeline-element.h"/> + <return-value transfer-ownership="none"> + <type name="none" c:type="void"/> + </return-value> + <parameters> + <instance-parameter name="self" transfer-ownership="none"> + <type name="TimelineElement" c:type="GESTimelineElement*"/> + </instance-parameter> + <parameter name="copy" transfer-ownership="none"> + <type name="TimelineElement" c:type="GESTimelineElement*"/> + </parameter> + </parameters> + </virtual-method> + <virtual-method name="get_layer_priority" invoker="get_layer_priority" version="1.16"> + <doc xml:space="preserve" filename="../subprojects/gst-editing-services/ges/ges-timeline-element.c">Gets the priority of the layer the element is in.
