to install everything onto the system into the specified prefix.
|
||||
Some additional steps will have to be performed to integrate
|
||||
with the distribution as shown below.
|
||||
|
||||
### PipeWire daemon
|
||||
|
||||
A correctly installed PipeWire system should have a pipewire
|
||||
process, a pipewire-media-session (or alternative) and an (optional)
|
||||
pipewire-pulse process running. PipeWire is usually started as a
|
||||
systemd unit using socket activation or as a service.
|
||||
|
||||
Configuration of the PipeWire daemon can be found in
|
||||
/usr/share/pipewire/pipewire.conf. Please refer to the comments in the
|
||||
config file for more information about the configuration options.
|
||||
|
||||
The daemon is started with:
|
||||
```
|
||||
systemctl --user start pipewire.service pipewire.socket
|
||||
```
|
||||
|
||||
If you did not start the media-session in pipewire.conf, you will
|
||||
also need to start it like this:
|
||||
```
|
||||
systemctl --user start pipewire-media-session.service
|
||||
```
|
||||
To make it start on system startup:
|
||||
```
|
||||
systemctl --user enable pipewire-media-session.service
|
||||
```
|
||||
you can write ```enable --now``` to start service immediately.
|
||||
|
||||
### ALSA plugin
|
||||
|
||||
The ALSA plugin is usually installed in:
|
||||
|
||||
On Fedora:
|
||||
```
|
||||
/usr/lib64/alsa-lib/libasound_module_pcm_pipewire.so
|
||||
```
|
||||
On Ubuntu:
|
||||
```
|
||||
/usr/lib/x86_64-linux-gnu/alsa-lib/libasound_module_pcm_pipewire.so
|
||||
```
|
||||
|
||||
There is also a config file installed in:
|
||||
|
||||
```
|
||||
/usr/share/alsa/alsa.conf.d/50-pipewire.conf
|
||||
```
|
||||
|
||||
The plugin will be picked up by alsa when the following files
|
||||
are in /etc/alsa/conf.d/
|
||||
|
||||
```
|
||||
/etc/alsa/conf.d/50-pipewire.conf -> /usr/share/alsa/alsa.conf.d/50-pipewire.conf
|
||||
/etc/alsa/conf.d/99-pipewire-default.conf
|
||||
```
|
||||
|
||||
With this setup, aplay -l should list a pipewire: device that can be used as
|
||||
a regular alsa device for playback and record.
|
||||
|
||||
### JACK emulation
|
||||
|
||||
PipeWire reimplements the 3 libraries that JACK applications use to make
|
||||
them run on top of PipeWire.
|
||||
|
||||
These libraries are found here:
|
||||
|
||||
```
|
||||
/usr/lib64/pipewire-0.3/jack/libjacknet.so -> libjacknet.so.0
|
||||
/usr/lib64/pipewire-0.3/jack/libjacknet.so.0 -> libjacknet.so.0.304.0
|
||||
/usr/lib64/pipewire-0.3/jack/libjacknet.so.0.304.0
|
||||
/usr/lib64/pipewire-0.3/jack/libjackserver.so -> libjackserver.so.0
|
||||
/usr/lib64/pipewire-0.3/jack/libjackserver.so.0 -> libjackserver.so.0.304.0
|
||||
/usr/lib64/pipewire-0.3/jack/libjackserver.so.0.304.0
|
||||
/usr/lib64/pipewire-0.3/jack/libjack.so -> libjack.so.0
|
||||
/usr/lib64/pipewire-0.3/jack/libjack.so.0 -> libjack.so.0.304.0
|
||||
/usr/lib64/pipewire-0.3/jack/libjack.so.0.304.0
|
||||
|
||||
```
|
||||
|
||||
The provided pw-jack script uses LD_LIBRARY_PATH to set the library
|
||||
search path to these replacement libraries. This allows you to run
|
||||
jack apps on both the real JACK server or on PipeWire with the script.
|
||||
|
||||
It is also possible to completely replace the JACK libraries by adding
|
||||
a file `pipewire-jack-x86_64.conf` to `/etc/ld.so.conf.d/` with
|
||||
contents like:
|
||||
|
||||
```
|
||||
/usr/lib64/pipewire-0.3/jack/
|
||||
```
|
||||
|
||||
Note that when JACK is replaced by PipeWire, the SPA JACK plugin (installed
|
||||
in /usr/lib64/spa-0.2/jack/libspa-jack.so) is not useful anymore and
|
||||
distributions should make them conflict.
|
||||
|
||||
|
||||
### PulseAudio replacement
|
||||
|
||||
PipeWire reimplements the PulseAudio server protocol as a small service
|
||||
that runs on top of PipeWire.
|
||||
|
||||
The binary is normally placed here:
|
||||
|
||||
```
|
||||
/usr/bin/pipewire-pulse
|
||||
```
|
||||
|
||||
The server can be started with provided systemd activation files or
|
||||
from PipeWire itself. (See `/usr/share/pipewire/pipewire.conf`)
|
||||
|
||||
```
|
||||
systemctl --user start pipewire-pulse.service pipewire-pulse.socket
|
||||
```
|
||||
|
||||
You can also start additional PulseAudio servers listening on other
|
||||
sockets with the -a option. See `pipewire-pulse -h` for more info.

# PipeWire Media Session
|
||||
|
||||
[PipeWire](https://pipewire.org) is a server and user space API to
|
||||
deal with multimedia pipelines. This includes:
|
||||
PipeWire Media Session is an example session manager for
|
||||
[PipeWire](https://pipewire.org).
|
||||
|
||||
- Making available sources of video (such as from a capture devices or
|
||||
application provided streams) and multiplexing this with
|
||||
clients.
|
||||
- Accessing sources of video for consumption.
|
||||
- Generating graphs for audio and video processing.
|
||||
|
||||
Nodes in the graph can be implemented as separate processes,
|
||||
communicating with sockets and exchanging multimedia content using fd
|
||||
passing.
|
||||
Note that we recommend the use of
|
||||
[WirePlumber](https://gitlab.freedesktop.org/pipewire/wireplumber) instead.
|
||||
|
||||

|
||||
[install](INSTALL.md) for instructions.
|
||||
|
||||
## Usage
|
||||
|
||||
The most important purpose of PipeWire is to run your favorite apps.
|
||||
|
||||
Some applications use the native PipeWire API, such as most compositors
|
||||
(gnome-shell, wayland, ...) to implement screen sharing. These apps will
|
||||
just work automatically.
|
||||
|
||||
Most audio applications can use either ALSA, JACK or PulseAudio as a
|
||||
backend. PipeWire provides support for all 3 backends. Depending on how
|
||||
your distribution has configured things this should just work automatically
|
||||
or with the provided scripts shown below.
|
||||
|
||||
PipeWire can use environment variables to control the behaviour of
|
||||
applications:
|
||||
|
||||
* `PIPEWIRE_DEBUG=<level>` to increase the debug level (or use one of
|
||||
`XEWIDT` for none, error, warnings, info,
|
||||
debug, or trace, respectively).
|
||||
* `PIPEWIRE_LOG=<filename>` to redirect log to filename
|
||||
* `PIPEWIRE_LOG_SYSTEMD=false` to disable logging to systemd journal
|
||||
* `PIPEWIRE_LATENCY=<num/denom>` to configure latency as a fraction. 10/1000
|
||||
configures a 10ms latency. Usually this is
|
||||
expressed as a fraction of the samplerate,
|
||||
like 256/48000, which uses 256 samples at a
|
||||
samplerate of 48KHz for a latency of 5.33ms.
|
||||
* `PIPEWIRE_NODE=<id>` to request a link to the specified node
|
||||
|
||||
### Using tools
|
||||
|
||||
`pw-cat` can be used to play and record audio and midi. Use `pw-cat -h` to get
|
||||
some more help. There are some aliases like `pw-play` and `pw-record` to make
|
||||
things easier:
|
||||
|
||||
```
|
||||
$ pw-play /home/wim/data/01.\ Firepower.wav
|
||||
```
|
||||
|
||||
### Running JACK applications
|
||||
|
||||
Depending on how the system was configured, you can either run PipeWire and
|
||||
JACK side-by-side or have PipeWire take over the functionality of JACK
|
||||
completely.
|
||||
|
||||
In dual mode, JACK apps will by default use the JACK server. To direct a JACK
|
||||
app to PipeWire, you can use the `pw-jack` script like this:
|
||||
|
||||
```
|
||||
$ pw-jack <appname>
|
||||
```
|
||||
|
||||
If you replaced JACK with PipeWire completely, `pw-jack` does not have any
|
||||
effect and can be omitted.
|
||||
|
||||
JACK applications will automatically use the buffer-size chosen by the
|
||||
server. You can force a maximum buffer size (latency) by setting the
|
||||
`PIPEWIRE_LATENCY` environment variable like so:
|
||||
|
||||
```
|
||||
PIPEWIRE_LATENCY=128/48000 jack_simple_client
|
||||
```
|
||||
Requests the `jack_simple_client` to run with a buffer of 128 or
|
||||
less samples.
|
||||
|
||||
|
||||
### Running PulseAudio applications
|
||||
|
||||
PipeWire can run a PulseAudio compatible replacement server. You can't
|
||||
use both servers at the same time. Usually your package manager will
|
||||
make the server conflict so that you can only install one or the
|
||||
other.
|
||||
|
||||
PulseAudio applications still use the regular PulseAudio client
|
||||
libraries and you don't need to do anything else than change the
|
||||
server implementation.
|
||||
|
||||
A successful swap of the server can be verified by checking the
|
||||
output of
|
||||
|
||||
```
|
||||
pactl info
|
||||
```
|
||||
It should include the string:
|
||||
```
|
||||
...
|
||||
Server Name: PulseAudio (on PipeWire 0.3.x)
|
||||
...
|
||||
```
|
||||
|
||||
You can use pavucontrol to change profiles and ports, change volumes
|
||||
or redirect streams, just like with PulseAudio.
|
||||
|
||||
|
||||
### Running ALSA applications
|
||||
|
||||
If the PipeWire alsa module is installed, it can be seen with
|
||||
|
||||
```
|
||||
$ aplay -L
|
||||
```
|
||||
|
||||
ALSA applications can then use the `pipewire:` device to use PipeWire
|
||||
as the audio system.
|
||||
|
||||
### Running GStreamer applications
|
||||
|
||||
PipeWire includes 2 GStreamer elements called `pipewiresrc` and
|
||||
`pipewiresink`. They can be used in pipelines such as this:
|
||||
|
||||
```
|
||||
$ gst-launch-1.0 pipewiresrc ! videoconvert ! autovideosink
|
||||
```
|
||||
|
||||
Or to play a beeping sound:
|
||||
|
||||
```
|
||||
$ gst-launch-1.0 audiotestsrc ! pipewiresink
|
||||
```
|
||||
|
||||
PipeWire provides a device monitor as well so that
|
||||
|
||||
```
|
||||
$ gst-device-monitor-1.0
|
||||
```
|
||||
|
||||
shows the PipeWire devices and applications like cheese will
|
||||
automatically use the PipeWire video source when possible.
|
||||
|
||||
### Inspecting the PipeWire state
|
||||
|
||||
To inspect and manipulate the PipeWire graph via GUI, you can use [Helvum](https://gitlab.freedesktop.org/ryuukyu/helvum).
|
||||
|
||||
Alternatively, you can use use one of the excellent JACK tools, such as `Carla`,
|
||||
`catia`, `qjackctl`, ...
|
||||
However, you will not be able to see all features like the video
|
||||
ports.
|
||||
|
||||
`pw-mon` dumps and monitors the state of the PipeWire daemon.
|
||||
|
||||
`pw-dot` can dump a graph of the pipeline, check out the help for
|
||||
how to do this.
|
||||
|
||||
`pw-top` monitors the real-time status of the graph. This is handy to
|
||||
find out what clients are running and how much DSP resources they
|
||||
use.
|
||||
|
||||
`pw-dump` dumps the state of the PipeWire daemon in JSON format. This
|

can be used to find out the properties and parameters of the objects
|

in the PipeWire daemon.

|

There is a more complicated tool to inspect the state of the server
|
||||
with `pw-cli`. This tool can be used interactively or it can execute
|
||||
single commands like this to get the server information:
|
||||
|
||||
```
|
||||
$ pw-cli info 0
|
||||
```
