NAME¶

libpipewire-module-example-filter - Example Filter 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>-<module-id>'.

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¶

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] }'
