+ Make GESAssetFileSource a subclass of it
+ Remove ges_asset_filesource_get_supported_type as it is now in GESAssetTimelineObject
+ Remove the GES_META_TIMELINE_OBJECT_SUPPORTED_FORMATS as it is useless now
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
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.
In the case of not properly set uri, we can keep using the same
TimelineFileSource changing its URI until its TrackObject could be created.
This is particularly usefull in the case of formatter trying to load filesource
when the file has been moved
This is usefull by any subclass of GESTimelineObject
+ Bind it in python
+ Fix the keyfile formatter tests
API: ges_timeline_object_set_supported_formats
API: ges_timeline_object_get_supported_formats
* max-duration is the total length of the File.
* supported-formats is the various track types this filesource can produce
trackobjects for. This should maybe be moved to parent classes in the
future
