Replace the v4l2 example with a more generic version that can add
any spa node to a remote graph
Make the dictionary items const
Add some info to nodes and factories. Add the node info to the node
properties. We can then set the media.class directly on the node,
instead of letting the monitor set it.
Debug node info in spa-inspect.
Do async operation on the audiotestsrc and videotestsrc differently.
* Fix use after free in error path
Memory pointed by 'handle' is used in error path but it is freed before jumping to interface_failed. Remove the wrong free. Memory pointed by 'handle' gets freed in the error handling path.
* Free 'bus' when dbus_bus_get_private fails
If dbus_bus_get_private fails memory pointed by 'bus' is never freed. Free it.
* Free 'impl' if dbus_bus_get_private fails
When dbus_bus_get_private fails the memory pointed by 'impl' is not freed. Free it.
Add signal handlers for daemon to shut down
Add destroy listeners for modules and do cleanup
Fix some leaks
Simplify port registration in new nodes
Hide some more data structures
Let the node implementation take care of the reuse_buffer signal because
then we can get to the graph nodes to find the destination port.
Destroy modules in core cleanup. Modules should undo everything they
have done.
Activate the link after we negotiated format and buffers.
Remove signals.
Rename callbacks -> events, use listeners to listen for events.
Callbacks are still used in spa for things you can listen to only
once.
Add hooks that contain protocol specific interfaces that can be used
to extend the protocol. This makes it possible to add new interfaces
to the protocol and implement the protocol specific data transport.
Move these protocol specific extension to the extensions directory.
