How to get the MPDroid nfo on the x2, x4 lines display in Volumio?
Example:

I would like to see it:

x2-lines:

Serengety & Polyphonic “Move!” (Terradactyl - 2009)
mp3 | 320kbps | 24bits | 44,1kHz

x4-lines:

Serengety & Polyphonic
“Move!”
Terradactyl - 2009
mp3 | 320kbps | 24bits | 44,1kHz

Or maybe mpd can not do it?

.SH NAME
MPDlcd - A tool to display MPD status on a lcdproc server
.
.
.SH SYNOPSIS
.B mpdlcd
.RI --help
.B mpdlcd
.RI [ options ]
.
.
.SH DESCRIPTION
.P
MPDlcd is a tool to display the status of a Music Player Daemon on a
.BR lcdproc (1)
server.
.P
It supports definition of custom screen patterns, and adapts them to the LCD width and height.
Configuration is done in the
.I /etc/mpdlcd.conf
file and can be overridden through command-line options.
.P
.BR mpdlcd
supports logging to syslog (local or remote), stdout or to a user-chosen file.
.
.
.SH SCREEN PATTERNS
The lines to display on the LCD are defined in a
.BR pattern,
which describes how fields should be arranged on each line.
Width is automatically adjusted to the screen size;
.BR mpdlcd
will automatically select a pattern whose length matches the screen height.
.
.SS Pattern syntax
The general format of a pattern line is:
.br
.B “{song format=’%(artist)s - %(title)s’,speed=2} {elapsed}/{total}”
The escaping character is
.BR “(rs” " (backslash):"
it will always make the next character non-special, anywhere in the string.
A pattern line may contain:
.br

  • Fields, enclosed in curly brackets – the
    .I {song…}
    ,
    .I “{elapsed}”
    or
    .I “{total}”
    blocks in the above example;
    .br
  • Raw text, which is displayed as is – the
    .I “‘space’”
    ,
    .I “’/’”
    blocks of the example.
    .
    The definition of a field is:
    .br
    .IR “{kind}” " or " “{kind option1=val1,option2=val2,…}”
    where
    .I kind
    is the field kind (see below), followed by an optional list of field options.
    The option values may be enclosed in simple quotes
    .IR “’” " or double quotes " *(lq “.”
    Any text which does not belong to a field will be displayed as is, in a fixed manner (using the
    .I fixed
    field).
    .
    .SS Fields
    .
    .P
    Elements displaying MPD informations are described in
    .IR fields “.”
    Those fields are refreshed at regular intervals, when related MPD data (song, elapsed time, state) is updated.
    Available fields are:
    .br
    .RS 5
    .HP
    .B fixed
    Display a fixed string.
    .br
    Accepts the following options:

    .I “mm:ss”
    format.
    .
    .HP
    .B bitrate

    .IR “192” ).
    .
    .HP
    .B sampling
    Sampling rate of the current song in kHz, as a 4+ digits field (e.g:
    .IR “192” ).
    .
    .HP

…And so… then one…

pattern2 = {song format="%(artist)s ,%(title)s’’ %(album)s '%(date)s",speed=2}
{???} {bitrate} {???} {sampling}

When the {sampling} parameter is used, then there is an error and does not start mpdlcd (((

Someone knows how to add {file type} , {bits} & {sampling} ???

Found and fixed a bug in

/usr/local/bin/python2.7/dist-packages/mpdlcd/display_fields.py

In one of the lines has been written “BitRateField”.

The right kind

[code]@register_field
class SamplingField(Field):
base_name = ‘sampling’
target_hooks = [‘status’]

def _format_sampling(self, sampling='44100:16:2'):
    rate = sampling.split(':')[0]
    return '%.1f' % float(rate)

def __init__(self, **kwargs):
    width = len(self._format_sampling())
    super(SamplingField, self).__init__(width=width, **kwargs)

def add_to_screen(self, screen, left, top):
    return screen.add_string_widget(self.name,
        self._format_sampling(), x=left, y=top)

def hook_changed(self, hook_name, widget, new_data):
    if hook_name == 'status':
        self.status_changed(widget, new_data)
    super(SamplingField, self).hook_changed(hook_name, widget, new_data)

def status_changed(self, widget, new_status):
    txt = self._format_sampling(new_status.get('audio') or '0:0:0')
    logger.debug(u"Setting widget %r to %r", widget.ref, txt)
    widget.set_text(txt)[/code]

But display shows “Sampling” only so…

44100.0 96000.0 192000.0

without “bits” & “channels” :frowning:(((

5

Is there any way to shorten 44100.0/96000.0/192000.0 ect to 44, 96,192 ?
