/**
|
|
* The simple endpoint link is an implementation of WpEndpointLink that
|
|
* expects the two linked endpoints to have nodes in the pipewire graph.
|
|
* When asked to create a link, it creates pw_link objects that will link
|
|
* the ports of the source node to the ports of the sink node.
|
|
*
|
|
* The GVariant data that is passed in create must be of type (uau),
|
|
* which means a tuple with the following fields:
|
|
* - u: a uint32 that is the ID of a node
|
|
* - au: an array of uint32 that are the IDs of the ports on this node
|
|
*
|
|
* Linking endpoints with multiple nodes is not supported by this implementation.
