CamillaDSP for piCorePlayer

I will keep trying then

Installation was super easy, thanks for the great work.
I currently have ~~two~~ one issues:
1) CamillaDSP seemingly does not reach to playback: muting, dimming have no effect. In pCP the output setting is camilladsp, in cDSP I entered plughw:CARD=sndrpihifiberry and state says RUNNING. The levels of the meters move. But muting and dimming still do not work.

You have to create a volume or loudness filter and put it in the pipeline for some/all channels in order to have any effect.
I assume, you solved the playback issue?

This should solve itself after some time - not sure, what I could do about this in the meantime :/
I already altered the script to use the pcp-load method as per Greg's suggestion.

Just for clarification:
Did loading openssl.tcz via the UI fail?
Or did it work, but the script still failed afterwards?

Yes, everything works.

UI says its already installed. Still cant get it to work :/

I made another clean image and resized to exactly 200MB this time. Usually tried more.

Do I need to do something with the md5 text included in the zip?
I unzipped and the imager only writes the img i think (using Raspberry Pi Imager v1.7.5).
Also tried with Win32 Disk Imager - 1.0.
I tried redownloading the files but still no luck. Should i go for the 32 bit version?

This is what i get (Sorry for posting something so long):

If piCorePlayer is running properly, you don't have to reinstall when the script aborts.
Just restarting is sufficient to restore the initial state, since the changes are only saved, if the script finishes without error.

You can try to switch the extension repo:
Go to Main Page > Extensions > then wait for the check to complete (until you see 5 green check marks)
Then go to > Available > Current repository > select "piCorePlayer mirror repository" and "Set".
Now you can run the script again.

Let me know, if this worked.

Nikyo · 2023-09-13 9:44 pm

Works. Awesome. Thank you so much

Another question, Johannes:

I am trying to integrate a script that connects a home automation knob with camillaDSP. This is the thread where I took it from: https://www.audiosciencereview.com/...pi-help-needed-with-python.40320/post-1524295 The knob is a zigbee device and it connects to camillaDSP via:

Zigbee rotary knob ---zigbee signal---> zigbee2mqtt zigbee to mqtt bridge ---mqtt---> Mosquitto mqtt broker ---mqtt---> Eclipse Paho mqtt Python Client ---python---> Pycamilladsp python library <------> Camilladsp

Everything is installed and working, the python script is the final piece in the chain. This is the blank script (takes your IP and knob ID):

#!python3
import json
import paho.mqtt.client as mqtt
import time
from camilladsp import CamillaConnection
HOST, PORT = "127.0.0.1", 1234

def on_connect(client, userdata, flags, rc, properties=None): #added properties=None to make sure it works with mqtt v3x and v5
# print("Connected with result code "+str(rc))

broker="192.168.xxx.xx"
# Subscribing in on_connect() means that if we lose the connection and
# reconnect then subscriptions will be renewed.
client.subscribe("zigbee2mqtt/0xdc8e95fffe8a7094",0)
global active
active = 1
global tone_db_change
tone_db_change = 0

def on_message(client, userdata, msg):
# print(msg.topic+" "+str(msg.payload))
payload = json.loads(msg.payload)
action_sense = payload['action']
global tone_db_change
global active
tone_db_change = 0
# print("active", active)
if action_sense == 'single':
if active == 1:
active = 2
elif active == 2:
active = 1
elif action_sense == 'rotate_right':
tone_db_change = 0.5
elif action_sense == 'rotate_left':
tone_db_change = -0.5
else :
tone_db_change = 0
cdsp = CamillaConnection(HOST, PORT)
cdsp.connect()
cdspconf = cdsp.get_config()
filters = cdspconf['filters']
bass = filters['Bass']
bass_parameters = bass['parameters']
# print(bass_parameters)
bass_gain = bass_parameters['gain']
# print(bass_gain)
treble = filters['Treble']
treble_parameters = treble['parameters']
# print(treble_parameters)
treble_gain = treble_parameters['gain']
# print(treble_gain)
if active == 1:
new_bass_gain = bass_gain + tone_db_change
if new_bass_gain > 9.5:
new_bass_gain = 9.5
elif new_bass_gain < -9.5:
new_bass_gain = -9.5
# print(new_bass_gain)
bass_parameters['gain'] = new_bass_gain
elif active == 2:
new_treble_gain = treble_gain + tone_db_change
if new_treble_gain > 9.5:
new_treble_gain = 9.5
elif new_treble_gain < -9.5:
new_treble_gain = -9.5
# print(new_treble_gain)
treble_parameters['gain'] = new_treble_gain
cdsp.set_config(cdspconf)

client = mqtt.Client(client_id="", clean_session=True, userdata=None, transport="tcp")
client.on_connect = on_connect
client.on_message = on_message

client.connect("192.168.xxx.xx")

client.loop_forever()

I receive the following error message when I start it:

tc@pCP:~$ python3 /home/tc/tonecontrol.py
Traceback (most recent call last):
File "/home/tc/tonecontrol.py", line 5, in <module>
from camilladsp import CamillaConnection
ModuleNotFoundError: No module named 'camilladsp'

What am I missing? The script was created for a different, the Raspi OS, but until here I got everything working on TinyCore. How can I make the script find camilladsp and connect?

Thanks in advance!

JWahle · 2023-09-18 4:47 pm

The 'camilladsp' module comes from the pycamilladsp python library.

There are several ways to set up python projects with dependencies, but the cleanest way I found is like I did to install CamillaGUI:

install PIP (python package manager)
create and activate a virtual python environment in some folder
install the dependencies (pycamilladsp and websocket_client)
put your python script inside the folder

Then you can run it like I did here.

You can either do this in /home/tc/yourproject and use the normal backup functionality
or create it in /usr/local/yourproject and create a module like I did here.
The piCorePlayer documentation contains more info on the backup mechanism and the extension mechanism.

sheeple · 2023-09-18 5:36 pm

Do you have an idea why the import function used in tonecontrol.py does not find camilladsp that your script installed?

from camilladsp import CamillaConnection
ModuleNotFoundError: No module named 'camilladsp'

I tried to start the tonecontrol.py in the virtual environment, and could not solve the issue.

Added: Maybe I activated the wrong way, I am not very knowledgeable and always work from descriptions.

JWahle · 2023-09-18 5:46 pm

Do you have an idea why the import function used in tonecontrol.py does not find camilladsp that your script installed?

Yes, because it is only installed locally for the python environment.
You can try to reuse the piCoreCDSP/CamillaGUI python environment for your script like this:

Code:

source /usr/local/camillagui/environment/bin/activate
python3 <absolute path to your python file>

LoekWhostalkin · 2023-10-15 9:08 am

Did a fresh pCP install and ran the script. All appears to work fine except when pausing the player I see a lot of warning messages in the log window repeating every second. The CamillaDSP GUI State is alternating between STALLED and PAUSED a couple of times per second while the Capture Sample Rate shows 88200.

I tried several Device settings but could not resolve this issue. Anyone has any clue?

LoekWhostalkin · 2023-10-15 9:36 am

Solved it by using the squeezelite -C option with a positive value i.e. 5. This will close the output after 5 seconds and the CamillaDSP State will go to Offline.

Hi, I tried to run the script, but it always fails, because it doesn't habe permission to edit /etc/asound.conf (or create files there.)
My installation is a freshly installed PCP. Isn't it normal, that users can't write in /etc?

sheeple · 2023-10-15 7:48 pm

You should be able to edit this vis the pCP interface.

LoekWhostalkin · 2023-10-15 8:43 pm

Indeed, that's what I did, using the "Close output setting".

/etc/asound.conf should be writable to the user tc.
How did you connect to the piCorePlayer?
Can you post the exact log message (last ~30 lines of the log)?

kh5 · 2023-10-16 6:44 pm

OK, now I chowned /etc/asound.conf to tc:staff and the script completed successfully. Are those the normal rights for the file? Because everything else in the directory is root:root. Could be that I recreated that file before and it used the permissions of the directory.

JWahle · 2023-10-17 11:20 am

I also noticed the permissions being a little weird, but normally the script works with a fresh pcp image.
That's why I did not fiddle with the permissions or try some weird sudo magic in my script.

kh5 · 2023-10-17 12:59 pm

Ok. Well, it completed in the end and everything is working now. Thanks for the script, that sure made it much easier.
