Controlling via websocket

If the websocket server is enabled with the -p option, CamillaDSP will listen to incoming websocket connections on the specified port.

If additionally the "wait" flag is given, it will wait for a config to be uploaded via the websocket server before starting the processing.

By default the websocket server binds to the address, which means it's only accessible locally (on the same machine). If it should be also available to remote machines, give the IP address of the interface where it should be available with the -a option. Giving will bind to all interfaces.

The available commands are:


Websocket server settings

Commands for reading and changing settings for the websocket server.

Read processing status

Commands for reading status parameters.

Config management

Commands for reading and changing the active configuration

Config reading and checking

These commands are used to check the syntax and contents of configurations. They do not affect the active configuration.

Controlling from Python using pyCamillaDSP

The recommended way of controlling CamillaDSP with Python is by using the pyCamillaDSP library.

Please see the readme in that library for instructions.

Controlling directly using Python

You need the websocket_client module installed for this to work. The package is called python-websocket-client on Fedora and python3-websocket on Debian/Ubuntu.

First start CamillaDSP with the -p option:

camilladsp -v -p1234 /path/to/someconfig.yml

Start Ipython. Import the websocket client and make a connection:

>In [1]: from websocket import create_connection
In [2]: ws = create_connection("ws://")

Get the name of the current config file

>In [3]: ws.send("getconfigname")
Out[3]: 19

In [4]: print(ws.recv())

Switch to a different config file

The new config is applied when the "reload" command is sent.

>In [5]: ws.send("setconfigname:/path/to/otherconfig.yml")
Out[5]: 52

In [6]: print(ws.recv())

In [7]: ws.send("reload")
Out[7]: 12

In [8]: print(ws.recv())

Get the current configuration

In [9]: ws.send("getconfig")
Out[9]: 15

In [10]: print(ws.recv())
  samplerate: 44100
  buffersize: 1024
  silence_threshold: 0.0
  silence_timeout: 0.0
    type: Alsa

Send a new config as yaml

The new config is applied directly.

>In [11]: with open('/path/to/newconfig.yml') as f:
    ...:     cfg=f.read()

In [12]: ws.send("setconfig:{}".format(cfg))
Out[12]: 957

In [13]: print(ws.recv())
