* Automatically creates RAOP (Airplay) sink devices based on zeroconf
|
||||
* information.
|
||||
*
|
||||
* This module will load module-raop-sink for each discovered sink
|
||||
* with the right parameters.
|
||||
* This module will load module-raop-sink for each announced stream that matches
|
||||
* the rule with the create-stream action.
|
||||
*
|
||||
* If no stream.rules are given, it will create a sink for all announced
|
||||
* streams.
|
||||
*
|
||||
* ## Module Options
|
||||
*
|
||||
* This module has no options.
|
||||
* Options specific to the behavior of this module
|
||||
*
|
||||
* - `stream.rules` = <rules>: match rules, use create-stream actions. See
|
||||
* \ref page_module_raop_sink for module properties.

||||
