Blank Screen when running vis about cli-visualizer HOT 36 CLOSED

I had this same problem, then I followed @zpsaras advice and edited the ./install.sh file to contain make ENABLE_PULSE=1 instead of make. I am running Ubuntu 16.04 with default audio settings on Unity.

from cli-visualizer.

Could you try with the line audio.pulse.source=1 completely removed. On most systems, it should auto detect the source correctly.

from cli-visualizer.

I'm going to close this ticket. I know that a few of the above issues are unrelated to the latest fix for ncurses, but this ticket has been a catch all for any blank screen issue for the visualizer and it is hard to distinguish exactly what issue someone is talking about. Anyone on the ticket who still has issues, fill free to open a new one for your specific error.

from cli-visualizer.

Blank screen on Debian Stretch resolved by installing libpulse-dev, changing make to make ENABLE_PULSE=1 and re-running ./install.sh. No need to restart pulse or remove previous build. Thanks to @gnuraspberry and @ArkaneCow for tips.

Thanks for vis!

from cli-visualizer.

Thx mate!
@luxpir and every one also (and vic ofc) <3

work for me (ubuntu 20)

from cli-visualizer.

Could you run it directly with ./build/vis?

from cli-visualizer.

I tried it last night and it was a no go for me (just gives a black screen, which let me quit by pressing q). I followed the steps above. Ubuntu gnome 16.04.

The only things I have in my config are:

audio.sources=pulse
audio.pulse.source=1
color.scheme=rainbow

pacmd list-sinks | grep -e 'name:' -e 'index' give me:
index: 0
name: <alsa_output.pci-0000_01_00.1.hdmi-stereo-extra1>

• index: 1
  name: <alsa_output.pci-0000_00_1f.3.analog-stereo>

gcc version 5.3.1

Haha not sure what info you need.
I see everyone getting it working, so it irks me that I'm having trouble.

I got projectM to run through pulseaudio. If this means anything.

Thanks for the response!

from cli-visualizer.

i took it out. still the same behavior.

Man. Not sure what I did. I'm gonna test this on another machine (Lubuntu 16.04). Will report asap.

from cli-visualizer.

I'm having the same issue https://i.imgur.com/6Ze4Eml.png and this is my config file for vis https://paste.ubuntu.com/17596215/ and this is the config file for mpd https://paste.ubuntu.com/17596253/. I am also running Ubuntu 16.04.

from cli-visualizer.

Could you post the output of pacmd list-sinks as well as the output of ls -altr /tmp/mpd.fifo?

from cli-visualizer.

Sure thing, here's the pacmd https://paste.ubuntu.com/17605212/ and here's the mpd.fifo https://paste.ubuntu.com/17605247/

from cli-visualizer.

So I have tried to reproduce this and unfortunately cannot. Could you try using mpd as a source instead of pulse? If it works, then it would narrow it down to a visualizer issue and not a pulseaudio issue.

To use mpd, the the vis config set

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

from cli-visualizer.

It still does not work.

from cli-visualizer.

When using mpd are you using, mpd to play music or some other player? Could you also post the output of vis -h?

from cli-visualizer.

Here's vis -h https://paste.ubuntu.com/17731385/ and when I normally listen to music, I use mpd+ncmpcpp

from cli-visualizer.

I'm on Arch Linux and I sometimes have a blank screen as well. Although I'm using pulse, not mpd, it might be worth a shot.

I can fix it by opening gnome-control-center (I believe Ubuntu uses the same or at least a similar control panel) and then in the Sound preferences I manually select my output again. Then after running vis, I get the visualizer again.

from cli-visualizer.

I went into my settings and this is all I have. https://my.mixtape.moe/dmqqfu.webm

from cli-visualizer.

Using Xubuntu 16.04:
In response to the original poster, the issue seems to be that you have run
./install.sh
after
make ENABLE_PULSE=1

Running vis from the build/ directory after
make ENABLE_PULSE=1
gives me a working spectrum. None of the other visualizations seem to work, but this is certainly better than a blank screen!

EDIT: Turns out the other visualizers work fine if I run (from build)
./vis -c ~/.config/vis/config

from cli-visualizer.

I'm also having this issue with Mint 18. I've tried running out of build/ and combinations of make ENABLE_PULSE=1 and ./install.sh. I have an identical setup to the OP, trying to use pulseaudio.

pacmd list-sinks
https://paste.ubuntu.com/23056481/
ls -altr /tmp/mpd.fifo
https://paste.ubuntu.com/23056483/

from cli-visualizer.

Same 'black screen' deal here. Using mopidy instead of mpd; to trying to use pulse instead of mpd. ncmpcpp for player.

pacmd list-sinks | grep -e 'name:' -e 'index'
results in:
* index: 0
name: <alsa_output.pci-0000_00_1f.3.analog-stereo>

so:

visualizer.fps=20
audio.sources=pulse
audio.pulse.source=0

run:
~/Downloads/cli-visualizer-master $ build/vis -c ~/.config/vis/config

Get BSOD (black screen of death)

Any ideas? I'm game to try things; running Mint 17.

from cli-visualizer.

Hello,

thanks for cli-sualizer,

it doesn't work for me either...I have a black screen. I use mopidy and ncmpcpp.

my vis conf :

my .mpdconf :
http://www.cjoint.com/c/FIBvhj7oGNa

thanks for any suggestion if you have time,

from cli-visualizer.

What ubuntu version are you using?

from cli-visualizer.

ubuntu mate, Ubuntu 15.10 wily.

from cli-visualizer.

try editing install.sh and change make to make ENABLE_PULSE=1

from cli-visualizer.

I enabled pulseaudio support by default for linux. I don't think this explains all of the issues here. Since I could not reproduce the issue in on my box, it is pretty hard to narrow down.

from cli-visualizer.

Can you identify the particulars of your box Darby?
Kernel? Distro?
Thanks!

Sorry for the late response here, I don't have as much as I'd like for side projects ( : I've pushed a few fixes in the last day. @jonwadsworth could you try re-building now?

from cli-visualizer.

I had this problem tonight, using pulseaudio. Not sure what this is worth but everything started working once I installed libpulse-dev like the README told me too. I was so sure that I had it though.. oh well. I'm running debian stretch, 4.8.0-1-amd64.

I was getting this exact error, removed my /bin/vis, deleted clone and re-cloned, used the install.sh and it worked on first try.

Sorry if this is useless information, I thought I would share here just in case it helps anything since I was having this issue.

from cli-visualizer.

It's working now for me! I'm not sure where I built the visualizer last time, so I totally re-cloned & re-built everything. Works PERFECT for me. Thanks!!

from cli-visualizer.

Still doesn't work for me. Not sure which commit made it start showing just a blank screen, but I'll try to bisect to find it.

from cli-visualizer.

I went pretty far back in time (1.2) and it still doesn't work, whether I build with ENABLE_PULSE=1 or not. This leads me to believe something changed in an external dependency. Also worth noting that the two non-default visualizers work when I cycle through them with space. It is the main/default one that does not work. This tells me it's not an issue with detecting pulseaudio or the correct sink.

Also the log file gets created but never written to, even with 777 permissions.

from cli-visualizer.

Based on your description what is probably broken something in ncurses, possibly wide characters or setting the background color. Could you set try setting the spectrum character in the config to a regular ascii character and then a UTF character, for example

visualizer.spectrum.character=#

visualizer.spectrum.character=❚

Also what system are you running, Arch or ubuntu?

from cli-visualizer.

@dpayne It was indeed the character. Both of those worked. Do you know what could have changed for me in the past few months to make this stop working like it used to?

I use Arch Linux, and my terminal is termite.

from cli-visualizer.

My guess is the ncurses library changed in someway. I'll debug some more tonight. It does work for on Arch for me, but my ncurses library is a custom build.

from cli-visualizer.

@rosshadden could you try again with the latest version on master.

from cli-visualizer.

@dpayne Latest version works great, thanks!
