NAME

       libpipewire-module-pipe-tunnel - Unix Pipe Tunnel

DESCRIPTION

       The pipe-tunnel module provides a source or sink that tunnels all audio to or from a unix pipe
       respectively.

MODULE NAME

       libpipewire-module-pipe-tunnel

MODULE OPTIONS

       • tunnel.mode: the desired tunnel to create. (Default playback)

       • tunnel.may-pause: if the tunnel stream is allowed to pause on xrun

       • pipe.filename: the filename of the pipe.

       • stream.props: Extra properties for the local stream.

       When tunnel.mode is capture, a capture stream on the default source is created. The samples captured from
       the source will be written to the pipe.

       When tunnel.mode is sink, a sink node is created. Samples played on the sink will be written to the pipe.

       When tunnel.mode is playback, a playback stream on the default sink is created. The samples read from the
       pipe will be played on the sink.

       When  tunnel.mode  is  source,  a  source  node  is  created. Samples read from the the pipe will be made
       available on the source.

       tunnel.may-pause allows the tunnel stream to become inactive (paused) when there is no data in  the  fifo
       or  when  the  fifo is full. For capture and playback tunnel.mode this is by default true. For source and
       sink tunnel.mode, this is by default false. A paused stream will consume no CPU and will resume when  the
       fifo becomes readable or writable again.

       When  pipe.filename  is  not given, a default fifo in /tmp/fifo_input or /tmp/fifo_output will be created
       that can be written and read respectively, depending on the selected tunnel.mode.

GENERAL OPTIONS

       Options with well-known behavior.

       • remote.name

       • audio.format

       • audio.rate

       • audio.channels

       • audio.position

       • node.latency

       • node.name

       • node.description

       • node.group

       • node.virtual

       • media.class

       • target.object to specify the remote name or serial id to link to

       When not otherwise specified, the pipe will accept or produce a 16 bits, stereo, 48KHz sample stream.

EXAMPLE CONFIGURATION OF A PIPE PLAYBACK STREAM

       # ~/.config/pipewire/pipewire.conf.d/my-pipe-tunnel.conf

       context.modules = [
       {   name = libpipewire-module-pipe-tunnel
           args = {
               tunnel.mode = playback
               #tunnel.may-pause = true
               # Set the pipe name to tunnel to
               pipe.filename = "/tmp/fifo_output"
               #audio.format=<sample format>
               #audio.rate=<sample rate>
               #audio.channels=<number of channels>
               #audio.position=<channel map>
               #target.object=<remote target node>
               stream.props = {
                   # extra sink properties
               }
           }
       }
       ]
