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.

libpipewire-module-example-filter

  • 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

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.

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 ]
      }
    }
}
