/**
|
|
* GESEditMode:
|
|
* @GES_EDIT_MODE_NORMAL: 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. When acting on the start of the
|
|
* element (#GES_EDGE_START), this will only MOVE the element, but not
|
|
* its toplevel parent. This can allow you to move a #GESClip or
|
|
* #GESGroup to a new start time or layer within its container group,
|
|
* without effecting other members of the group. When acting on the end
|
|
* of the element (#GES_EDGE_END), this will END-TRIM the element,
|
|
* leaving its toplevel unchanged.
|
|
* @GES_EDIT_MODE_RIPPLE: The element is edited in ripple mode: moving
|
|
* itself as well as later elements, keeping their relative times. This
|
|
* edits the element the same as #GES_EDIT_MODE_NORMAL. In addition, if
|
|
* acting on the element as a whole, or the start of the element, any
|
|
* toplevel element in the same timeline (including different layers)
|
|
* whose start time is later than the *current* start time of the MOVED
|
|
* element will also be MOVED by the same shift as the edited element.
|
|
* If acting on the end of the element, any toplevel element whose start
|
|
* time is later than the *current* end time of the edited element will
|
|
* also be MOVED by the same shift as the change in the end of the
|
|
* edited element. These additional elements will also be shifted by
|
|
* the same shift in layers as the edited element.
|
|
* @GES_EDIT_MODE_ROLL: The element is edited in roll mode: swapping its
|
|
* content for its neighbour's, or vis versa, in the timeline output.
|
|
* This edits the element the same as #GES_EDIT_MODE_TRIM. In addition,
|
|
* any neighbours are also TRIMMED at their opposite edge to the same
|
|
* timeline position. When acting on the start of the element, a
|
|
* neighbour is any earlier element in the timeline whose end time
|
|
* matches the *current* start time of the edited element. When acting on
|
|
* the end of the element, a neighbour is any later element in the
|
|
* timeline whose start time matches the *current* start time of the
|
|
* edited element. In addition, a neighbour have a #GESSource at its
|
|
* end/start edge that shares a track with a #GESSource at the start/end
|
|
* edge of the edited element. Basically, a neighbour is an element that
|
|
* can be extended, or cut, to have its content replace, or be replaced
|
|
* by, the content of the edited element. Acting on the element as a
|
|
* whole (#GES_EDGE_NONE) is not defined. The element can not shift
|
|
* layers under this mode.
|
|
* @GES_EDIT_MODE_TRIM: The element is edited in trim mode. When acting
|
|
* on the start of the element, this will START-TRIM it. When acting on
|
|
* the end of the element, this will END-TRIM it. Acting on the element
|
|
* as a whole (#GES_EDGE_NONE) is not defined.
|
|
* @GES_EDIT_MODE_SLIDE: The element is edited in slide mode (not yet
|
|
* implemented): moving the element replacing or consuming content on
|
|
* each end. When acting on the element as a whole, this will MOVE the
|
|
* element, and TRIM any neighbours on either side. A neighbour is
|
|
* defined in the same way as in #GES_EDIT_MODE_ROLL, but they may be on
|
|
* either side of the edited elements. Elements at the end with be
|
|
* START-TRIMMED to the new end position of the edited element. Elements
|
|
* at the start will be END-TRIMMED to the new start position of the
|
|
* edited element. Acting on the start or end of the element
|
|
* (#GES_EDGE_START and #GES_EDGE_END) is not defined. The element can
|
|
* not shift layers under this mode.
|
|
*
|
|
* 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).
