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.

The available commands are:

Controlling from 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())
