ges: Various functions that return a GError don't set it in all error paths
Examples are ges_clip_add_child_to_track()
and ges_timeline_new_from_uri()
. They return NULL
in various cases without setting the GError
.
If returning NULL
should not be considered an error but normal behaviour then it would be necessary to mark the return value as nullable
, if all NULL
cases should be considered an error then it must not be marked as nullable
.
