Problem with Volumio v2.389

[rikardo1979]

Trying to make this working on Volumio v2.389 (Audiophonics RaspDAC V3) with no luck. All I can see on display is the pyPiper start logo and then 'STOP' permanently displayed

Nothing in log apart from

Hi there. Thanks again for this very nice piece of code for different mediaplayers :-)

I have the same problem running a HD44780 16x2 display. It is displaying song and start/stop logo. The funny things is that the display work even though nothing is changed in the pydpiper.service file. Not any ExecStart line is uncomment. only ExecStop file is in use... It will not respond to any change in a uncomment line regarding time, weather, driver, pages etc... time is only updated every 5th min. Please let me know if i can do any trouble shooting... Log file is the same as rikardo1979.

Regards Mikkel

Sorry for everyone that's been having trouble. I've had another project in flight that has eaten all of my development time. I'll take a look at the installation on the current version of Volumio this week.

[W1tch3d]

No soucy, it's OK now for me, i had a problem with docker.

This problem comes and goes, I haven't been able to pinpoint it. But most of the times it works for me

[dhrone]

If you get a chance, try the latest build and see if it resolves your problem. Starting from a fresh install of Volumio 2.389 issue the following commands from within the /home/volumio directory.

git clone https://github.com/dhrone/pydPiper cd pydPiper sudo ./install_docker.sh Make sure that you get a message indicating that Docker has installed successfully sudo ./install_volumio.sh This will run a new configure program to set up the system for your display and distribution and then create and install a systemd service file for pydPiper.

If the problem continues, shut down the service and then run pydPiper manually adding the --showupdates flag to see if you are receiving updates from Volumio correctly.

So... sudo systemctl stop pydpiper sudo systemctl disable pydpiper

sudo /usr/bin/docker run --network=host --privileged -v /var/log:/var/log:rw -v /home/volumio/pydPiper:/app:rw dhrone/pydpiper:v0.31-alpha python /app/pydPiper.py --showupdates

With the showupdates flag set, every time pydPiper receives new data, it will print a message.

NOTE: I have only tested this version with Volumio 2.389 and an HD44780 20x4 line display.

[Saiyato]

I think I found why I experienced the problem, I created a plugin for Volumio (https://github.com/Saiyato/volumio-pydpiper-plugin) and the systemd unit started pydPiper, but when Volumio was started, I restarted the pydPiper service.

What I did now, was remove the systemd unit file, symlink to the one in the plugin directory (so I could write without sudo) and disable the service. In which case Volumio controls the service, plugin disabled = no start, and it only starts after Volumio has been initialized.

At this point I rarely (once in the past two weeks) see this problem.

[MikkelLau]

The display is working great and it is easy to install with the new config :)

Is it some how possible to retrieve the 'bitrate' info (kbps). It is not present when using the --showupdates. It is present when running this with MoOde audio but not here in Volumio. kHz and Bit are retrieved from 'tracktype'

I am trying to run a 'conditional' in the sequences section of the pages file. I am trying to read the 'stream' state when playing flac but i can't make it work. Is this all wrong: { 'name':'playartist_flac', 'duration':14, 'conditional':"db['stream']=='flac' " }, I have a canvas called 'play artist_flac'... Thanks again

[dhrone]

pydPiper does look for the variable samplerate from Volumio. If it is not showing up in --showupdates though it is not being sent by Volumio. You can verify what Volumio is producing by going to the /dev page of the web interface (see https://volumio.github.io/docs/User_Manual/SSH.html).

For your conditional, you are testing against the wrong variable. I think you want tracktype. Something like...

'conditional':"db['tracktype'][:4].lower()=='flac' "

[Saiyato]

Correct, the bitrate is not being sent by Volumio, mpd however does have this info:

volumio@volumioboss:~$ telnet localhost 6600
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

OK

It's been a while since I dug into this code, but maybe this can be concatenated to the Volumio results that do exist?

/dev gives me the following:

{
	"status": "play",
	"position": 11,
	"title": "Path [Vol. 1]",
	"artist": "Apocalyptica",
	"album": "Cult (Special Edition)",

	"uri": "mnt/NAS/iTunes/Apocalyptica/Cult (Special Edition)/1-01 Path [Vol. 1].m4a",
	"trackType": "m4a",
	"seek": 8577,
	"duration": 186,
	"samplerate": "44.1 KHz",

	"volume": 0,
	"mute": false,
	"stream": "m4a",
	"updatedb": false,

}

I think you should be able to calculate kbps, but easiest would be to ask MPD for the value.

[dhrone]

If what you are looking for is instantaneous bitrate then I think MPD is your only source. Unfortunately, it is not currently possible to have two sources active if both are producing information at the same time.

I have been thinking of extending the metadata subsection of pydPiper but do not know when I'm going to get to it. This is an area of the code that has been difficult to deal with as each of the distributions handles metadata somewhat differently. It has needed clean-up for awhile. FYI, if I do upgrade that subsystem, it will likely require that the page files be modified.

[MikkelLau]

Hi guys. Thanks for the input :-) Yes Volumio is not sending the bitrate. We are not the only ones looking for this and there is a forum here, were others are requesting the same https://volumio.org/forum/bit-rate-display-t8248.html The conditional setting was simply to add another condition other than 'webradio' and 'Not webradio'. Its only a nice to have feature! :-) Thanks for your help and it reads the 'flac' state:-)

Hello everyone and thank you Saiyato for a great plug. Unfortunately, after the last volumio update, I cannot install the plugin. During installation I have the following errors in the console:

Please let me know if it is still possible to install the plugin on the Raspberry. I have a Raspberry PI 3+ with volumio 2.917, LCD HD44780 16x2 installed.

Thank you for your answer and best regards

Hi @Jozin7 ,

Unfortunately this is not something @dhrone or I can fix, I've briefly tried investigating another way to run containers (podman, or crun or containerd), but I haven't been able to make it work on Jessie yet. Your best bet is to upgrade to Volumio 3.1xx and up, that way Docker will install fine again :smile:

[Jozin7]

Hello @Saiyato and thank you again for the great plugin :-)

After upgrading Volumio to version 3.198, I installed the pydPiper plugin without any problems. I added a GPIO buttons plugin to handle basic commands and my old DSR tuner REVOX starts its second life :-)

I greet you cordially and wish you all the best
