The GNL API changed to go from a model where user could
enable/disable updates in the composition, which leaded to races
in many places, to a model where any positioning change in the
composition is not directly done but 'cached' and then the user
has to commit those changes so they become effective in the media
processing stack.
The new API in GES is pretty similare and is basically copy
pasting this new design.
We still need to see if in some context it would make sense to add
a mode where we would commit any changes ourself at the end of our
operation for basic use cases.
Removed APIs:
ges_timeline_enable_update
ges_timeline_is_updating
ges_track_enable_update
ges_track_is_updating
New APIs:
ges_track_commit
ges_timeline_commit
+ Fix tests (starting using GESTestClip instead of GESCustomClip)
Now the height is not only growing, but can also go down, as the value
is just simply computed
API:
GESContainer::compute_height virtual method
+ Fix tests (we still need a round of modernisation, making use of
assets where it makes sense)
There is no reason to use those method outside of GES, so remove them,
cleaning the API and making it easier for users.
Removed APIs:
-----------
* ges_clip_create_track_element
* ges_clip_create_track_elements
This way we let the possibility to the user to actually do it, but we avoid him to do it
without knowing it is absolutely not recommanded to.
API:
+ ges_uri_clip_asset_request_sync
... Not the other way round.
+ Add and enhance debugging info on the way
The user should not be responsible for removing the GESTrackElements from
GESTracks, instead, removing it from a GESClip should imply removing
it from any GESTrack it is in.
This patch changes sensibly the behaviour when we remove a
GESTrackElement from a GESTrack, not remoing it from the GESClip it is
in. *But*, users should never remove a GESTrackElement from a GESTrack
anyway. The testsuite has been updated to that new behaviour.
+ 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 do it in TimelineFileSource which does not make sense.
At the same time we set AUDIO | VIDEO as default supported types as it is more
likely to be what subclasses support. If it is not the case, they need to
specify it as shown in ges-timeline-custom-timeline-source.c
+ Fix the tests accordingly
It was using deprecated URI, and can not be used in real life anymore.
Also remove the ges_formatter_default_new method ges_formatter_new_for_uri
that are useless now
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);
In TimelineTitleSource We do not add a TrackAudioTestSource in the audio track
anymore as it was a hack to work around the fact that we used not to have gap
support, now we do, remove related tests
+ timeline: Add a snapping-distance property
+ Bump the GLib dependency to 2.28 in the mean time as we need some functions from GSequence that only landed
+ Update the testsuite accordingly
API: GESTimeline:snapping-distance property
API: ges_timeline_object_edit
API: ges_timeline_object_ripple
API: ges_timeline_object_ripple_end
API: ges_timeline_object_roll_start
API: ges_timeline_object_roll_end
API: ges_timeline_object_trim_start
API: ges_track_object_edit
API: GESEdge enum
API: GESEditMode enum
This property was firstly added to TrackFileSource, but in the end, it makes
more sense for it to be directly in TrackOject as it can be usefull in other cases.
