timeline-tree: simplify and fix editing 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.

timeline: re-handle clip children track selection The way a clip's track elements are added to tracks was re-handled. This doesn't affect the normal usage of a simple audio-video timeline, where the tracks are added before any clips, but usage for multi-track timelines has improved. The main changes are: + We can now handle a track being selected for more than one track, including a full copy of their children properties and bindings. (Previously broken.) + When a clip is split, we copy the new elements directly into the same track, avoiding select-tracks-for-object. + When a clip is grouped or ungrouped, we avoid moving the elements to or from tracks. + Added API to allow users to copy the core elements of a clip directly into a track, complementing select-tracks-for-object. + Enforced the rule that a clip can only contain one core child in a track, and all the non-core children must be added to tracks that already contains a core child. This extends the previous condition that two sources from the same clip should not be added to the same track. + Made ges_track_add_element check that the newly added track element does not break the configuration rules of the timeline. + When adding a track to a timeline, we only use select-tracks-for-object to check whether track elements should be added to the new track, not existing ones. + When removing a track from a timeline, we empty it of all the track elements that are controlled by a clip. Thus, we ensure that a clip only contains elements that are in the tracks of the same timeline, or no track. Similarly, when removing a clip from a timeline. + We can now avoid unsupported timeline configurations when a layer is added to a timeline, and already contains clips. + We can now avoid unsupported timeline configurations when a track is added to a timeline, and the timeline already contains clips.

timeline: re-handle clip children track selection The way a clip's track elements are added to tracks was re-handled. This doesn't affect the normal usage of a simple audio-video timeline, where the tracks are added before any clips, but usage for multi-track timelines has improved. The main changes are: + We can now handle a track being selected for more than one track, including a full copy of their children properties and bindings. (Previously broken.) + When a clip is split, we copy the new elements directly into the same track, avoiding select-tracks-for-object. + When a clip is grouped or ungrouped, we avoid moving the elements to or from tracks. + Added API to allow users to copy the core elements of a clip directly into a track, complementing select-tracks-for-object. + Enforced the rule that a clip can only contain one core child in a track, and all the non-core children must be added to tracks that already contains a core child. This extends the previous condition that two sources from the same clip should not be added to the same track. + Made ges_track_add_element check that the newly added track element does not break the configuration rules of the timeline. + When adding a track to a timeline, we only use select-tracks-for-object to check whether track elements should be added to the new track, not existing ones. + When removing a track from a timeline, we empty it of all the track elements that are controlled by a clip. Thus, we ensure that a clip only contains elements that are in the tracks of the same timeline, or no track. Similarly, when removing a clip from a timeline. + We can now avoid unsupported timeline configurations when a layer is added to a timeline, and already contains clips. + We can now avoid unsupported timeline configurations when a track is added to a timeline, and the timeline already contains clips.

Handle changing playback rate Before this patch, NLE and GES did not support NleOperations (respectively GESEffects) that changed the speed/tempo/rate at which the source plays. For example, the 'pitch' element can make audio play faster or slower. In GES 1.5.90 and before, an NleOperation containing the pitch element to change the rate (or tempo) would cause a pipeline state change to PAUSED after that stack; that has been fixed in 1.5.91 (see #755012 [0]). But even then, in 1.5.91 and later, NleComposition would send segment events to its NleSources assuming that one source second is equal to one pipeline second. The resulting early EOS event (in the case of a source rate higher than 1.0) would cause it to switch stacks too early, causing confusion in the timeline and spectacularly messed up output. This patch fixes that by searching for rate-changing elements in GESTrackElements such as GESEffects. If such rate-changing elements are found, their final effect on the playing rate is stored in the corresponding NleObject as the 'media duration factor', named like this because the 'media duration', or source duration, of an NleObject can be computed by multiplying the duration with the media duration factor of that object and its parents (this is called the 'recursive media duration factor'). For example, a 4-second NleSource with an NleOperation with a media duration factor of 2.0 will have an 8-second media duration, which means that for playing 4 seconds in the pipeline, the seek event sent to it must span 8 seconds of media. (So, the 'duration' of an NleObject or GES object always refers to its duration in the timeline, not the media duration.) To summarize: * Rate-changing elements are registered in the GESEffectClass (pitch::tempo and pitch::rate are registered by default); * GESTimelineElement is responsible for detecting rate-changing elements and computing the media_duration_factor; * GESTrackElement is responsible for storing the media_duration_factor in NleObject; * NleComposition is responsible for the recursive_media_duration_factor; * The latter property finally fixes media time computations in NleObject. NLE and GES tests are included. [0] https://bugzilla.gnome.org/show_bug.cgi?id=755012 Differential Revision: https://phabricator.freedesktop.org/D276
