The default padding I introduced in d4f81fb4e6 is
actually only 4 pointers and on 32bit platforms already smaller than the union.
Replace it with a fixed 64byte padding. Don't add the normal padding for now.
Fixes#755822
While this technically is an abi break, we decided to do this:
1) the struct is documented to be internal
2) the struct is alloced and freed inside the library
3) there are no public methods that receive or return instances
4) the only code known to use this struct are classes containd here
In order for user to be able to track changes in the value set in
GstTimedValueControlSource the following signals have been added:
* value-added
* value-removed
* value-changed
To be able to use a GstControlPoint to be marshalled into the signals,
the GstControlPoint structure is now registerd as a GBoxed type.
New API:
~~~~~~~
* GstTimedValueControlSource::value-added
* GstTimedValueControlSource::value-removed
* GstTimedValueControlSource::value-added
https://bugzilla.gnome.org/show_bug.cgi?id=737616
Move most of the code to a GstTimedValueControlSource. Split out the trigger
'interpolation mode' to a new control source class. Move tests and examples to
new api. Update docs.
Fixes#610338
