Instead of doing it at the time of resetting `object->in_composition`
when user calls `gst_bin_remove` do it after we actually removed
it from the object thread, and do it in the `nle_object_reset`
method where it belongs

We were implementing the logic for moving/trimming elements specific
to SourceClip but this was not correct ass the new timeline tree allows
us to handle that for all element types in a generic and nice way.
This make us need to have groups trimming properly implemented in the
timeline tree, leading to some fixes in the group tests.
This adds tests for the various cases known to not be handled properly
by the previous code.

Unless the pipeline is in certain modes, we do not want to try and link
every track. The previous debug message implied this, but the method did
not actually end early.
Also, we always end early if we receive a track that is neither video
nor audio.
Previous usage of the property proxy-target seemed to alternate between
the two definitions:
+ The asset we are the default proxy of
+ The asset we are in the proxy list of
Now, the latter definition is used, which seems more useful to a user
since knowing the latter can easily allow you to find out the former.
The previous behaviour of ges_asset_set_proxy (asset, NULL) was not very
clear. It is now defined so that it clears all the proxies for 'asset'.
This means that after this call, the GESAsset:proxy property will indeed
be NULL.
Also fixed:
+ We can call ges_asset_set_proxy (asset, proxy) when 'proxy' is already
in the proxy list of 'asset'.
+ Handling of removing the default proxy in ges_asset_unproxy. This was
sending out the wrong notifies.
+ Prohibiting circular proxying. Before we could only prevent one case,
we should now be able to prevent all cases. This will prevent a hang
in ges_asset_request.
The test_proxy_asset test needs the internal method
ges_asset_finish_proxy. The test also uses the associated internal methods
ges_asset_try_proxy and ges_asset_cache_lookup. However, these are
marked with GES_API in ges-internal.h, which allows us access to them
here.
The new method is not marked as GES_API because it would not allow us to
remove the method in the future without removing it from the symbols list.
We do not want to add to the problem.
The test was simply commented out since we may wish to support tests
that access internal methods in the future using meson.
Fix the ownership in ges_asset_request. This should be transfer-full,
but for proxies it would fail to add a reference. Also,
ges_asset_cache_put was leaking memory if the asset already existed.
We should not be accepting ges_asset_set_proxy (NULL, proxy) as part of
the API! This behaviour was used internally in combination with
ges_asset_try_proxy, which is called on a still loading asset, so it was
moved to ges_asset_finish_proxy.
Previously, we tested that the given priority was `>0`, when it seems
that `>=0` was intended. A priority of `-1` means leave the priority
unchanged, whilst a priority of 0, or more, means move to this layer
priority.
Stop overwriting the ->list_children_properties virtual method in
subclasses because the timeline element class handles everything itself
anyway.
Note that containers already automatically add the children properties of
their child elements in ges_container_add.
Previously, we were setting the inpoint_offset using the start offset in
the duration callback!
Also added a notify for when the duration is changed in the child start
callback.
Previously, either the track or track_type arguments had to be specified
in order to find **any** track elements. Now, you can specify neither,
which will match any track element, of the specified type.
In the test_timeline.test_auto_transition, the corresponding xges only
has one layer, so we should only expect one layer when we extract the
timeline. This fixes a change that was missing from commit
d3e2cf55e3
If a clip is already part of a layer, then adding it to another layer
should fail. Previously, in this case, `ges_layer_add_clip` was adding a
reference to the clip instead, without subsequently giving up ownership.
This meant that the clip would be left with an unowned reference.
This has now been corrected by also calling `unref` after the
`ref_sink`.
Note that, since `clip` is already part of `current_layer`, it should
already be non-floating, so the `ref_sink`-`unref` should do nothing
overall. But we keep both to make the ownership (transfer floating/none)
explicit.
The method steals ownership of `copied_from`, so should be responsible
for unreffing it. Also make sure we fail when `layer != -1`, since this
functionality is not supported.
We try to do our best to have the video frames scaled the best way
to fill most space on the final frames, keeping aspect ratio. The user
can later on rescale or move the sources as usual but it makes the
default behaviour a better and more natural especially now that we
set default restriction caps to the video tracks.
And fix the unit test to take that change into account
This way the user can easily know how the clip would look like
if no scaling was applied to the clip, this is useful to be able
to properly position the clips with the framepositionner element.
We used to always call the `->set_child_property` virtual method
of the object that `ges_timeline_element_set_child_property` was called
from, but that means that, in the case of referencing GESContainer
children properties from its children, the children wouldn't know
what child property have been set, and the children override wouldn't
be takent into account, in turns, it means that the behaviour could be
different in the setter depending on parent the method was called,
which is totally unexpected.
We now make sure that the vmethod from the element that introduced the
child property is called whatever parent method is called, making the
behaviour more uniform.
Fix the python override to make sure that new behaviour is respected.
By default, video track output full HD@30fps, this makes the behaviour
of clip position much more understandable and guarantess that we
always have a framerate.
The user can modify the values whenever he wants
