Editing has been simplified by breaking down each edit into a combination of three basic single-element edits: MOVE, TRIM_START, and TRIM_END. Each edit follows these steps: + Determine which elements are to be edited and under which basic mode + Determine which track elements will move as a result + Snap the edit position to one of the edges of the main edited element, (or the edge of one of its descendants, in the case of MOVE), avoiding moving elements. NOTE: in particular, we can *not* snap to the edge of a neighbouring element in a roll edit. This was previously possible, even though the neighbour was moving! + Determine the edit positions for clips (or track elements with no parent) using the snapped value. In addition, we replace any edits of a group with an edit of its descendant clips. If any value would be out of bounds (e.g. negative start) we do not edit. NOTE: this is now done *after* checking the snapping. This allows the edit to succeed if snapping would cause it to go from being invalid to valid! + Determine whether the collection of edits would result in a valid timeline-configuration which does not break the rules for sources overlapping. + If all this succeeds, we emit snapping-started on the timeline. + We then perform all the edits. At this point they should all succeed. The simplification/unification should make it easier to make other changes.

/**
|
|
* 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 and later 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 and later 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).
