libpipewire-module-example-filter - Man Page

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-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.

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

context.modules = [
{   name = libpipewire-module-example-filter
    args = {
      node.description = "Example Filter"

          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] }'
