(OS X) does not output anything onto screen, just a blank terminal

[wahidrahim]

I followed the instructions from this issue as well: #24
Still no output.

Here is my config:

##Refresh rate of the visualizers. A really high refresh rate may cause screen tearing. Default is 20.
#visualizer.fps=20

##Sets the audio sources to use. Currently available ones are "mpd" and "alsa"Sets the audio sources to use.
##Currently available ones are "mpd", "pulse" and "alsa". Defaults to "mpd".
audio.sources=mpd

##vis tries to find the correct pulseaudio sink, however this will not work on all systems.
##If pulse audio is not working with vis try switching the audio source. A list can be found by running the
##command pacmd list-sinks  | grep -e 'name:'  -e 'index'
#audio.pulse.source=0

##Defaults to "/tmp/mpd.fifo"
mpd.fifo.path=/tmp/mpd.fifo

##If set to false the visualizers will use mono mode instead of stereo. Some visualizers will
##behave differently when mono is enabled. For example, spectrum show two sets of bars.
#audio.stereo.enabled=false

##Specifies how often the visualizer will change in seconds. 0 means do not rotate. Default is 0.
#visualizer.rotation.secs=10

##Configures the samples rate and the cutoff frequencies.
#audio.sampling.frequency=44100
#audio.low.cutoff.frequency=22050
#audio.high.cutoff.frequency=30


##Configures the visualizers and the order they are in. Available visualizers are spectrum,lorenz,ellipse.
##Defaults to spectrum,ellipse,lorenz
#visualizers=spectrum,ellipse,lorenz


##Configures what character the spectrum visualizer will use. Specifying a space (e.g " ") means the
##background will be colored instead of the character. Defaults to " ".
#visualizer.spectrum.character=#

##Spectrum bar width. Defaults to 2.
#visualizer.spectrum.bar.width=2

##The amount of space between each bar in the spectrum visualizer. Defaults to 1. It's possible to set this to
##zero to have no space between bars
#visualizer.spectrum.bar.spacing=1

##Available smoothing options are monstercat, sgs, none.
#visualizer.spectrum.smoothing.mode=monstercat

##This configures the falloff effect on the spectrum visualizer. Available falloff options are fill,top,none.
##Defaults to "fill"
#visualizer.spectrum.falloff.mode=fill

##Configures how fast the falloff character falls. This is an exponential falloff so values usually look
##best 0.9+ and small changes in this value can have a large effect. Defaults to 0.95
#visualizer.spectrum.falloff.weight=0.95

##Margins in percent of total screen for spectrum visualizer. All margins default to 0
#visualizer.spectrum.top.margin=0.30
#visualizer.spectrum.bottom.margin=0.10
#visualizer.spectrum.right.margin=0.10
#visualizer.spectrum.left.margin=0.10

##Reverses the direction of the spectrum so that high freqs are first and low freqs last. Defaults to false.
#visualizer.spectrum.reversed=false

##This configures the sgs smoothing effect on the spectrum visualizer. More points spreads out the smoothing
##effect and increasing passes runs the smoother multiple times on reach run. Defaults are points=3 and passes=1
#visualizer.sgs.smoothing.points=3
#visualizer.sgs.smoothing.passes=1


##Configures what character the ellipse visualizer will use. Specifying a space (e.g " ") means the
##background will be colored instead of the character. Defaults to "█".
#visualizer.ellipse.character=#

##The radius of each color ring in the ellipse visualizer. Defaults to 2.
#visualizer.ellipse.radius=2


##Configures what character the lorenz visualizer will use. Specifying a space (e.g " ") means the
##background will be colored instead of the character. Defaults to "█".
#visualizer.lorenz.character=#

##Specifies the color scheme. The color scheme must be in ~/.config/vis/colors/ directory. The default scheme is "colors".
#colors.scheme=rainbow

What does your mpd config look like?

I have the same issue.

There's nothing in the vis.log. Also, which vis gives me the correct /usr/local/bin/vis.

my config:

audio.sources=mpd
mpd.fifo.path=/tmp/mpd.fifo

mpd.conf:

music_directory         "~/Music"
    playlist_directory      "~/.mpd/playlists"
    db_file                 "~/.mpd/mpd.db"
    log_file                "~/.mpd/mpd.log"
    pid_file                "~/.mpd/mpd.pid"
    state_file              "~/.mpd/mpdstate"
    auto_update             "yes"
    auto_update_depth       "2"
    follow_outside_symlinks "yes"
    follow_inside_symlinks  "yes"

    audio_output {
      type                  "osx"
      name                  "CoreAudio"
      mixer_type            "software"
    }

    audio_output {
      type                  "fifo"
      name                  "my_fifo"
      path                  "/tmp/mpd.fifo"
      format                "44100:16:2"
    }

    decoder {
      plugin                "mp4ff"
      enabled               "no"
    }

    bind_to_address     "127.0.0.1"
    port                        "6600"

    user                       "my uname"

I also verified that /tmp/mpd.fifo was created.

EDIT: my bad, I did get it to work now with ncmpcpp. Just not with Mopidy + Spotify - but that's probably out the scope of this issue.

[be-ez]

For those who are interested in getting this working in OSX with Mopidy and Spotify. I added an output to the Mopidy config so a /tmp/mpd.fifo file is created.

I added this to my Mopidy.conf file.

[audio]
output = tee name=t t. ! queue ! autoaudiosink t. ! queue ! audioresample ! audioconvert ! audio/x-raw,rate=44100,channels=2,format=S16LE ! wavenc ! filesink location=/tmp/mpd.fifo

Edit: Some references.
Discussion Board I got the idea from
mopidy advanced audio docs

wow ... thanks @be-ez ... it works ...

[brettinternet]

@be-ez thanks for sharing that link, I meant to follow up. For anyone else finding this you can see my mopidy.conf here.

To document some of my other findings: When I initially set up mine on macOS, I had a python error about a missing libspotify framework in /Library/Frameworks. If you get this error, simply run brew info libspotify to see where homebrew has installed your libspotify package. Create a folder in /Library/Frameworks called libspotify.framework, then create a symlink in /Library/Frameworks/libspotify.framework with something like:

ln -s /usr/local/Cellar/libspotify/12.1.51/lib/libspotify

After that brew services start mopidy should run without error.
