* @short_description: Base Class for the elements of a #GESTrack
*
2020-01-15 14:46:02 +00:00
* 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.

2020-01-15 14:46:02 +00:00
* 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.

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

*
* The default value is determined by the #GESTrackElementClass
* @default_has_internal_source class property. For most

* that have a potentially *static* source, such as #GESImageSourceClass

* 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).
