I'm trying to seek on the currently playing song and I'm getting the following error:

  CommandError: [5@0] {} unknown command "seekcur"

Using MPDClient.seek() works fine, but it requires specifying a song and I'd rather just to be able to default to the current song.

Some entries in my MPD library seem to cause a UnicodeDecodeError. I'm using Python3.

Script:

#!/usr/bin/python

import mpd 

client = mpd.MPDClient()
client.connect("localhost", 6600)
print(client.mpd_version)

client.iterate = True
allinfo = client.listall()

for item in allinfo:
  print(item)

client.close
client.disconnect()

Output:

....

I am using mpd 0.17.0, Python 3.2.3 and the latest python-mpd2 from today.

Is it possible to create a new persistent empty playlist?

The command seekcur() works for all modes except random mode as expected. When i'm using the random mode, i.e. seekcur("+10"), mpd jumps to the next song and starts playing at the time position of the last song + 10 secs.

I think this is not the normal behaviour.

print(client.mpd_version): 0.18.0
mpd --version : 0.18.12
(maybe a bug, if not, please use + if you cannot figure out the correct version 0.18.+)

python-mpd2 version: 0.5.3

Hi. This patch allows to build python-mpd in non-unicode locale environment and is compatible with both py2 and py3. Please consider applying it to the master.

Hello,
I'm trying to list my albums grouped by artists, but I don't really get how to do that : your documentation indicates that list() can take an argument "group", so I try to do that:

    mpdclient.connect(server, port)
    mpdclient.list("album", "group", "albumartist")
mpd.CommandError: [2@0] {list} not able to parse args

Did I misunderstood your doc or do I have to do this in 2 operations (listing artists, and then listing the albums for each artist of the list) ?
Thank you

Is there a way to cancel an idle() command?

In MPD you can send a noidle command to cancel a previously issued idle command. But in python-mpd2 the idle command is blocking, so there seems to be no way to cancel it.

The best approach would probably be an asynchronous approach (maybe involving future objects) with blocking helper functions around them. Would this be solved by #30?

As MPD 0.19 introduces some changes to the protocol, i guess there will be changes to the GREAT python-mpd2 lib. See the below link:

http://git.musicpd.org/cgit/master/mpd.git/plain/NEWS?h=v0.19

Hi Mic92,

I got a problem using python-mpd2 version 0.4.2.

I'm running:
Python 2.7.3,
PyQt4.9.1,
mpd 0.16.8,
Windows 7 professional SP1 ( English Edition)

The problem i got is the playlist rename method.
My english is bad, but the following fuzzy code may give you some clues to understand what i mean:

import sys, mpd

sys.getfilesystemencoding()
'mbcs'

m = mpd.MPDClient()
m.connect('localhost', 6600)

old_playlist_name = "大" # Name in Chinese which means 'Big' in English, and it is already existed in m.listplaylists()
new_playlist_name = "New Name"

m.rename(old_playlist_name, new_playlist_name)

Error below (The same logic with the above code):

Traceback (most recent call last):
File "xplayer.py", line 2171, in OKPressed
handler.rename(self.selectedItem, givenName)
File "c:\Python27\lib\site-packages\mpd.py", line 491, in decorator

File "c:\Python27\lib\site-packages\mpd.py", line 235, in _read_line
raise CommandError(error)
mpd.CommandError: [50@0] {rename} No such playlist

The most strange thing is:

new_name = unicode(Chinese_Characters)
m.save(new_name)

Works fine.
So i really don't know why.

Please help, thanks a lot.

I am sorry if i am missing something very obvious but according to the docs , client.status() should return the next song and the nextsongid. If these have been deprecated, could someone point me in the right direction on how (when the playlist is in random mode) to pick a song from the current playlist and get it to play immediately.

Hi,
I've found this module very interesting. Is it possible, to add some commands?
It would be nice when it's possible to use:
add
insert

to manipulate the queue.
Regards Jörg

Hi,
I have the following problem: Every once in a while my Raspberry Pi re-detects my USB Soundcard. After that, I can't set the volume via mpdclient.setvol(x), it just shows '0' in mpdclient.status()['volume']. However, no exception is thrown.
Now, here's the funny thing. Running mpc also shows volume 0%. But running mpc volume 50 errors with problems setting volume. Now, if I try setvol(x) again with mpdclient, it also raises an exception: mpd.CommandError: [52@0] {setvol} problems setting volume

I think this exception should to be thrown, without having to use mpc before.

I may have wrong, but actually the noidle command doesn't works.

If I want to stop idling to quering the status for instance, I have to cancel idling with the noidle command.

client.send_idle('player')
client.noidle()

mpd.PendingCommandError: Cannot execute 'noidle' with pending commands

I'm working on a patch to cancel the idle command when sending noidle, but any insights is welcome.

It would be nice to get help.

OS: Mac OS X 10.9.4
MPD: 0.18.13 (Installed by homebrew: brew install mpd)
python-mpd2: 0.5.3

For debugging, i inserted one line "print('Line from client: ', line)" into the _read_line method of mpd.py. Like below: (Please see the third line)

    def _read_line(self):
        line = self._rfile.readline()
        print('Line from client: ', line)
        if self.use_unicode:
            line = decode_str(line)
        if not line.endswith("\n"):
            self.disconnect()
            raise ConnectionError("Connection lost while reading line")
        line = line.rstrip("\n")
        if line.startswith(ERROR_PREFIX):
            error = line[len(ERROR_PREFIX):].strip()
            raise CommandError(error)
        if self._command_list is not None:
            if line == NEXT:
                return
            if line == SUCCESS:
                raise ProtocolError("Got unexpected '%s'" % SUCCESS)
        elif line == SUCCESS:
            return
        return line

Then i do the following:

import mpd
handler = mpd.MPDClient(use_unicode=True)
handler.timeout = 10
handler.connect('localhost', 6600)

handler.deleteid('117')
('Line from client: ', 'OK\n')           # Print the info i inserted before.

Then after several minutes later, i do the following(before the following action i do nothing at all, just wait inside the ipython prompt):
(And i can confirm that ID as '119' is already existed in the current playlist)

handler.deleteid('119')

As MPD has just released version 0.18 which introduced some new stuff.
Check change log at: http://git.musicpd.org/cgit/master/mpd.git/plain/NEWS?h=release-0.18

It would be nice to let python-mpd2 keep up to date with the upstream.

OSX 10.9.x
MPD: 0.18.11 (installed by homebrew)
Python 2.7.x
python-mpd2 0.5.3

import mpd

handler = mpd.MPDClient(use_unicode=True)
handler.connect('localhost', 6600)

Then sometimes, not every time, there will be problem like below:

Without some API docs it's basically impossible to infer how to use this library. A basic function listing with parameters and their meanings would be sufficient.

I'm writing a web-based front end to MPD. I instantiate and connect MPDClient when my program starts. At first calling commands works fine, but after some time of inactivity,

  File "/home/ztang/music/music.py", line 19, in queue

A further attempt to connect:

Is there a way to avoid the ConnectionError? Will I have to catch the exception and reconnect, or connect and disconnect every time I issue a command?

The MPDClient.seekcur function always raises the following:

mpc.seekcur(60)
Traceback (most recent call last):

The grouping version of count command behave unexpectedly IMHO:

>>> cli = mpd.MPDClient()
>>> cli.connect(host='/run/mpd/socket', port=42)
>>> cli.count('group', 'albumartist')
{'albumartist': ['art00', 'art01',…], 
 'playtime': ['123', '321', …],
 'songs': ['1', '2',…]}
>>> #  idem with:
>>> cli.count('genre', 'Rock', 'group', 'albumartist')

I would expect a list of object of that kind instead:

>>> cli.count('group', 'albumartist')
[ {'albumartist': 'art00', 'playtime': '123', 'songs': '1'},
  {'albumartist': 'art01', 'playtime': '321', 'songs': '2'},
…]

This object does not require extra processing to link grouping values with its playtime/songs stats.

I had a quick look at the raw MPD output, I think this might be tricky since the delimiter changes depending on the function signature. I don't have a straight forward solution to submit.

That's it
Thanks for your work

I code using the send_idle() function with a follow on select() that has been largely working well. I can then use a different thread to send a no_idle command.

                MPD2.send_idle()
                # do this in event loop
                canRead = select([MPD2], [], [])[0]
                logging.debug(str(canRead))
                if canRead:
                    logging.debug('retrieving idle event')
                    event = MPD2.fetch_idle()

The above works great. However, if there is a network glitch between the client and the mpd server, the select above never returns and I can never detect and reset the connection.

If I add a timeout on the select to recover from the glitch, the Python Select documentation say the returned list (canRead) should be empty.

canRead = select([MPD2], [], [], <timeout in seconds>)[0]

However, I always get MPD2 returning in the list. When the code tries to fetch_idle(), the connection is automatically closed and a "Connection lost while reading line" is thrown.

What am I missing? Unless the select() returns an empty list on timeout, there is no way to know there was a timeout and to avoid calling fetch_idle()

It would be great if you could add an explanation of dict returned by MPDClient.status() because I really do not understand the difference between MPDClient.status()['time'] and MPDClient.status()['elapsed']. And is there no way to get the absolute length of a song in seconds?

Sending commands in python-mpd is not thread-safe. But this feature is often required in gui apps. Therefore locking is needed.

Hi Mic92,

Sorry to bother you again.
I work on this problem couple of days already, still have no clue, please help me out.

I am using watchdog to watch the filesystem change of MPD music directory,
once there is/are change(s) happened inside music directory,
my program will ask MPD to update it's database by using your library.

My problem is:
I found when i upload a little more audio files(more than 10 files?) to the music directory of MPD, then my program will generate lots of error.
It seems that while MPD is updating it's database, at the same time if you ask for other information will not be handled. Sometime it is OK, you can get the data you want, but sometimes it will fail, especially for method: 'handler.status()', lot of 'KeyError' information reported.

Some of the error info below:

$ python xplayer.py

Hi
probably not a bug but i'm using 0.5.5 and client status do no seem to report time or elapsed on a mpd 0.16 server?
Also client.status()['time'] or client.status()['elapsed'] return a KeyError: 'time' or KeyError: 'elapsed'

could you please clarify the usage or is it a limitation of the versions Im using atm.
a command line mpc status return the expected value: for ex 0:05/7:40 (1%)
mpc status

Creating a client, and then having the server stop gives one exception the first time client.status is called, and then a different exception after that. Subsequent reconnects also fail.

I think stickers documentation is wrong, missing get, set, del, list and find to make sense.

cf. : http://pythonhosted.org/python-mpd2/topics/commands.html#stickers

Hi and thank you for this project!

When mpd is idle (after calling client.stop()) for a couple of hours, I cannot successfully call client.play() again. I am aware of ConnectionErrors that can occur so I catch them in my script. In this case, however, I get a BrokenPipeError (sometimes I don't get an error at all, but nevertheless mpd won't start to play reproducibly).

I wrote a test script (find it here: https://gist.github.com/speendo/0d9c1a028d045de3f7a6) to track the error down.

I ran this script on my raspberry pi with nohup python3 test_mpd.py &.

Here's a traceback of the Error (found in nohup.out):

Can you help me find the source of this problem (or even solve it)?

Is it possible to wait until MPDclient().update() is complete?

i.e. mpc update --wait

Volume method is not implemented but still in documentation.
http://pythonhosted.org/python-mpd2/topics/commands.html#MPDClient.volume

Hi, I think this issue is related to some of the others (#31, #64). After some time of working great, I consistently get this exception:

  File "example.py", line 90, in update
    self.status = self.client.status()
  File "mpd.py", line 629, in decorator
    return wrapper(self, name, args, bound_decorator(self, returnValue))
  File "mpd.py", line 252, in _execute
    self._write_command(command, args)

  File "mpd.py", line 258, in _write_line
    self._wfile.write("%s\n" % line)
ValueError: I/O operation on closed file.

It is connected to a mopidy instance, which continues to function. I suspect the connection is broken, but I'm not sure if mpd2 should handle this, or I should proceed like the users in the referenced issues and reconnect myself.

Suspect the cause is self._sock.makefile(...), file objects on Windows automatically convert \n into \r\n

Commands cause random seemingly unrelated errors (eg. Expected key 'volume', got 'repeat' for Adding to playlist)

Hello,
Song information may be or not be encoded as UTF-8 string, and as I know, mpd does not convert them into UTF-8. So would it be better not forcing UTF-8 encoding in python3?
I did this for python3 in my own branch.

MPD supports the command
delete a:b
to delete all files from position a to b in the current playlist. To use this in python-mpd2, one must do something like

which is not very nice; I think the possibility to write

instead would be better. I didn't figure out how to implement this because I don't completely understand the way commands are created in python-mpd2, otherwise I'd supply a pull request. :-)

Hi,
I just noticed that your package does not appear in the "Python 3 Packages" section of PyPi. Since Py3k support is one of the outstanding features of this library (and also to promote porting programs to python 3) this should be changed.

As far as I can see it suffices to add the line

Programming Language :: Python :: 3

in setup.py.

Is there a reason why the MPDClient class is old-style (eg. doesn't have a signature of class MPDClient(object):)?

I am having trouble interpreting the documentation for the stored playlist load function, to load a specific entry in a stored playlist using a range.

for example, to load entry #2 in a playlist, I have tried:
client.load('playlistname', '2:2')
client.load('playlistname', '2', '2')
client.load('playlistname', ('2', '2'))
client.load('playlistname', (2, 2))
client.load('playlistname', ['2', '2'])

I always get a: mpd.CommandError: [2@0] {load} wrong number of arguments for "load"

Can some one give me an example?

The commands documentation is currently missing any lists present in the description of a function, for example in MPDClient.idle() there should be a list of subsystems.

sometimes tags in mpd protocol can be duplicates of one another.
This esp. happens if one tagged his library using beets.

This is how raw protocol serves those tags:

currentsong

OK

in python-mpd2 the 2 "track" values will be represented as one string value:

>>> print(file['track'])
[1, 1]
>>> type(file['track'])
<class 'str'>

python-mpd2 could check for key:value on parsing and if multi-values for one key are identical simply merge them. Otherwise represent them as a list.

Alternatively represent all duplicate tags as lists, even if all values are identical. Personally I prefer the first option :)

It appears that currentsong() does not return the song's title, just the file name (as well as other useful bits of information), or am I just using it wrong?

python-mpd could be ported to asyncio (tulip), which would make it easy to integrate in a multitude of main loops from web servers to guis.

i've started porting, and have the very basics running (tcp connection, not blocking on connection and issuing basic commands, integration in gtk3 using gbulb), but it's only a small part. (haven't touched unix sockets (should be trivial) or idle (should interact greatly); iterate mode would have to be standard in this mode, even if it's not exposed).

i'm not sure yet where this takes the code base. my changes so far are small, but i don't think it's feasible to have ifs everywhere around to keep the same code working both blockingly and via asyncio. it might be possible to provide a blocking mode from that code base (where every blocking call is a thinly wrapped nonblocking call), but unless the python2.7 backport makes progress, that'll be python3.3+ only anyway.

(porting to asyncio is just starting, so patterns for keeping both a classical and an asynchronous interfaces can be expected to show up. let's see where this goes.)

this is currently an "i spend an hour on it when i need a break" project for me, so if you want to see progress soon, you'll have to join in or wait for me to be bored with everything else again :-)

I'm using mpd2 along with PiMusicBox to control Spotify on a Rpi. I'm struggling to get good search results back from Spotify via MPD. I do the following

for a specific track by a specific artist

result = client.find("artist", artist_to_find, "title", track_to_find)

or just for an artist:

result = client.find("artist", artist_to_find)

The artist/track search usually gets results but the artist only search often returns nothing - even if the search (artist_to_find) is something like "David Bowie".

Can anyone advise the best way to get Spotify results via MPD?

Thanks

I am new to python and python-mpd2 so I may be using this package incorrectly, but I cannot determine the source of my problem. I have a python-mpd2-based client on one RaspberryPi and a standard mpd on another Pi.

My client connects to the remote mpd and then listens for IR remote commands. When the IR remote command is sent, the client formats the request and relays it to the mpd. So far I have volume up and down working nicely. The client never disconnects and supposedly keeps the connection to the mpd open all the while.

However, if I leave the client for a period of time (an hour or so), just listening for IR commands, when I finally send a command, the client fails with a broken pipe (socket.error?) or sometimes a "ConnectionError: Connection lost while reading line". The mpd is still running and playing, although another mpd client (mpc) elsewhere has been been manipulating it.

Is it normal to expect that the original socket connection would be dropped over time or usage by a different mpd client? I have read all the documents I can find, and have failed to find any reason for the problem. I am expecting to have to catch the error and re-connect, but I'd like to know the root cause.
