NAME

       libpipewire-module-example-filter - Example Filter

DESCRIPTION

       The example filter is a good starting point for writing a custom filter.

       We refer to the source code for more information.

MODULE NAME

       libpipewire-module-example-filter

MODULE OPTIONS

       • node.description: a human readable name for the filter streams

       • capture.props = {}: properties to be passed to the input stream

       • playback.props = {}: properties to be passed to the output stream

GENERAL OPTIONS

       Options with well-known behavior. Most options can be added to the global configuration or
       the individual streams:

       • remote.name

       • audio.rate

       • audio.channels

       • audio.position

       • media.name

       • node.latency

       • node.description

       • node.group

       • node.link.group

       • node.virtual

       • node.name : See notes below. If not specified, defaults to 'filter-PID-MODULEID'.

       Stream only properties:

       • media.class

       • node.name : if not given per stream, the global node.name will be prefixed with 'input.'
         and 'output.' to generate a capture and playback stream node.name respectively.

EXAMPLE CONFIGURATION OF A VIRTUAL SOURCE

       # ~/.config/pipewire/pipewire.conf.d/my-example-filter.conf

       context.modules = [
       {   name = libpipewire-module-example-filter
           args = {
             node.description = "Example Filter"
             capture.props = {
                 audio.position = [ FL FR ]
                 node.passive = true
             }
             playback.props = {
                 node.name = "Example Filter"
                 media.class = "Audio/Source"
                 audio.position = [ FL FR ]
             }
           }
       }
       ]

       pw-cli -m lm libpipewire-module-example-filter '{ audio.position=[FL FR] }'
