Unlike ges_container_add, this lets you set the index and will check
that track selection did not fail. This is useful for time effects whose
addition would create an unsupported timeline configuration.
Also can use the clip add error in ges_timeline_add_clip to let the user
know when adding a clip to a layer that its in-point is set larger than
the max-duration of its core children.
Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-editing-services/-/merge_requests/177>
Only allow elements that were created by ges_clip_create_track_elements
(or copied from such an element) to be added to a clip. This prevents
users from adding arbitrary elements to a clip.
As an exception, a user can add GESBaseEffects to clips whose class
supports it, i.e. to a GESSourceClip and a GESBaseEffectClip.
This change also introduces a distinction between the core elements of a
clip (created by ges_clip_create_track_elements) and non-core elements
(currently, only GESBaseEffects, for some classes). In particular,
GESBaseEffectClip will now distinguish between its core elements and
effects added by the user. This means that the core elements will always
have the lowest priority, and will not be listed as top effects. This is
desirable because it brings the behaviour of GESBaseEffectClip in line
with other clip types.
GstDiscoverer objects were leaked by tests making the leaks detector
unusable.
Introduce ges_deinit(), similiar to gst_deinit(), doing some cleanup
before exiting the process.

GESLayer is now responsible for setting clips priorites. Also
GESClip top effects priorities are now set by the
ges_clip_set_top_effect_index method, the user should never call
ges_timeline_element_set_priority as it will anyway be overriden
by GES itself.

Fix all tests as we now have 1 priority inside the layer
dedicated to transitions (basically no source clip will
ever have a priority of 0 inside a layer).

And simplify the way we start computing children priority
making min_priority already relative to the clip itself.

I got some trouble with
arc land
and I wanted to push the 3 commit coming after this revert as 3
different commits but they ended up being all squash into one single
commit, which is clearly not cool for later bisecting and blaming.
Reverting that commit and re pushing those 3 commits as they were
supposed to be.
This reverts commit 9fe15ef435.
The priority handling of clip is now handled by GESLayer itself, and
handling clip as a ordered list should be implemented in GESLayer itself
too, this way the user can decide to switch mode at any time instead of
And fix all the tests as we need to wait for the project to be loaded
to check the reference count of the timeline (as we keep a ref on the
timeline in project to later emit "loaded" on idle).
+ Fix tests as necessary (Do not use agingtv as it can be "applied" on any TrackType
and is not representative of what happens IRL)
We already had the infrastructure so the user can have the control over where to add
the elements (through the "select-track-for-object" signal). We now make use of that
signal everytime a GESClip is added to a GESTimelineLayer. This make user's life easier,
and object responsability clearer.
Modifies some API:
ges_timeline_object_create_track_objects now take a GESTrackType instead of a
GESTrack as second argument, and return a GList instead of a boolean
ges_timeline_object_create_track_object now take a GESTrackType instead of a
GESTrack as second argument
We used to have a ges_track_object_get/set_child_property that was in
fact letting user set/get various properties at once, rename it to
get/set_properties, and implement:
API:
ges_track_object_get_child_property (GESTrackObject *object, const gchar
*property_name, GValue * value);
ges_track_object_set_child_property (GESTrackObject *object, const gchar
*property_name, GValue * value);
