Hi,
I wanted to compose the stream example, but the entrypoint start.sh from the shairport.yml is missing. I also tried the entrypoint.sh but its also not in the image.

Hello I have Mopidy and Snapcast running in docker and wanted to get this LedFx container setup to work with them but am having a couple of issues.

My Mopidy has an audio output that is
output = audioresample ! audioconvert ! audio/x-raw,rate=48000,channels=2,format=S16LE ! filesink location=/tmp/snapfifo

From what i can tell this LedFx container is looking for an output in a file called stream. So if i change the Mopidy out to
output = audioresample ! audioconvert ! audio/x-raw,rate=48000,channels=2,format=S32LE ! filesink location=/tmp/stream

LedFx can access that, however that then renders my snapcast unavailable as it is wanting snapfifo.

So my question is how would i get this all working together, what files do i need to edit to have this all work in sync. If this is a mopidy config file setting, and someone has an example i can look at that would be great. I'm just a little confused at how this all works together.

It seems like the docker container does not contain the current version of LedFx. It would be great if you could update it.

Thanks in advance.

I am running the container on a libreelec installation (inside libreelec) on an RPI4 with following cmd:

docker run \
-p 8888:8888 \
-v ~/ledfx-config:/app/ledfx-config \
-v ~/audio:/app/audio \
-e HOST=192.168.1.222 \
-e FORMAT='-r 48000 -f S16_LE -c 2' \
--restart always \
--name ledfx -h ledfx shirom/ledfx

The ledfx device is showing up on the snapserver webinterface on the libreelec-Addon, but no sound is received.

The other problem is, that even a successful configuration would prevent using HDMI-Audio and Snapserver at the same time.

Maybe it's just simple and I don't get it:
I need a audio-pipe that transfers the audio from libreelec (all sounds) to the container on the same machine.
What options are needed to run the container and receive audio while playing audio with the "ALSA: vc4-hdmi-0" device?

Thanks anyway for your work!

Hi,

big thanks for the Snapcast-Integration 👍

Could you update the Dockerfile to use always the latest upstream version of Snapclient (0.26.0 at the moment)?
Currently the Dockerfile uses apt which result in an old version (0.15.0).

Hello,
I've seen that there was an integration for Home Assistant, which is deprecated. The developer seemed to move directly to the LEDfx team. In the old project https://github.com/YeonV/ledfxrm it is mentioned that an integration with MQTT will come. Is there a chance to get this into this docker container? I just tested it out today, the container works great. I nearly containerized everything I could and I am happy to get an LEDfx container that works out of the box.
It would be great to see the MQTT integration primarily to check the state of LEDfx.
Regards,
Harald

This repo seems like a total gem, can't wait to try it out. One thing before I start (and I'll report back on how it went): @ShiromMakkad can you confirm it's possible to have another docker container of sorts that is used as an AirPlay receiver, so when I AirPlay something to it, it can forward the stream to your LedFx container and therefore control the LEDs?
AirPlay is mentioned in the documentation but it isn't too clear for me. Sorry!

Hello,

We have connected a chromecast to the audio input of a computer. I can hear the audio if i pipe the microphone to the internal speakers using qpwgraph. I however can't seem to figure out how to pipe this microphone to the stream file

I'm running this container on UnRaid.
I'm taking a chrome cast, splitting the audio using an HDMI audio splitter, then passing the 3.5mm audio in via one of these:
https://www.amazon.co.uk/dp/B010N8UP6C?psc=1&ref=ppx_yo2ov_dt_b_product_details

I'm also passing /dev/hidraw0 (confirmed correct) as a device via docker options.

However, the USB device doesn't show in the container, only ALSA pulse and default, neither of which seem to have the audio stream.

I found performance very poor on Raspberry Pi3B, Nanopi Neo3 and NanopiR4S. After a few minutes the animation would lag severely behind the audio (Squeezebox/LMS). After longer times (10 min or so), when the audio was stopped, the animation would continue for several more seconds.
Testing more extensively on the R4S running Armbian and docker, I found that running the container 'privileged' strongly improves performance. Limiting to specific CPU's also seems to help. This is my adjusted compose file:

--------------------------------------
version: '2'

services:
  ledfx:
    image: shirom/ledfx
    container_name: ledfx
    environment: 
      - FORMAT=-r 44100 -f S16_LE -c 2
      - SQUEEZE=1
    ports:
      - 8888:8888
    network_mode: host
    volumes:
      - ./ledfx-config:/app/ledfx-config
      - ~/audio:/app/audio
    cpuset: '4,5'
    privileged: true

--------------------------------------

in non-privileged mode, the performance was 'best' (but still very poor) when limiting to only 1 CPU.
With the compose above, it is now running OK for 7 WLED devices with about 1500 pixels in total.

There is a ENTRYPOINT entrypoint.sh in the Dockerfile however it is nowhere to be found in this repo

Hi, could you help me how to use your image with an external USB sound card? I went through your examples, but I got nothing.

Thanks very much.

Hello!

Building the image myself gives me this error:
standard_init_linux.go:219: exec user process caused: exec format error

Hello!

I'd like to use this image with PulseAudio however I'm unsure about how I would go about that... I'm trying to avoid using snapcast entirely.

I'm getting this:
[Logs]    [2022-9-28 15:33:03] [ledfx] ALSA lib seq_hw.c:466:(snd_seq_hw_open) open /dev/snd/seq failed: No such file or directory
[Logs]    [2022-9-28 15:33:03] [ledfx] [ERROR   ] ledfx.integrations.midi        : Unable to enumerate midi devices: MidiInAlsa::initialize: error creating ALSA sequencer client object.

I'm using this inside a balenasound image without snapcast with an external sound card

Hello,
I would like to run this docker in the architecture arm64, is it possible?
What would be the steps to manage it?
Best regards

Hey, thanks for that amazing project.
You saved me a few more weeks figuring everything out!

There are new versions of LedFX, do you compile them yourself and upload the images to docker or is it a broken automatic build?

Hello, tell me please is there an opportunity to connect a microphone?

Hi,

I'm using this image as my goal is to stream music from Spotify to LedFX and create sound reactive WLED effect.
My problem is that I don't know where should I configure my Spotify account, is it somewhere in Snapserver container?

I've tried several docker-compose using different images, with no luck so far.
My current configuration uses docker-compose.yml from this project examples.
https://github.com/ShiromMakkad/LedFxDocker/blob/master/examples/snapcast.yml

version: '3'

services:
snapserver:
image: ivdata/snapserver
container_name: snapserver
ports:
- 1704:1704
- 1705:1705
volumes:
- ./snapcast:/tmp/snapcast
ledfx:
image: shirom/ledfx
container_name: ledfx
environment:
- HOST=snapserver
ports:
- 8888:8888
volumes:
- ./ledfx-config:/root/.ledfx

Second issue I have is that ledfx container is complaining about ALSA and reporting following error in logs:

ALSA lib seq_hw.c:466:(snd_seq_hw_open) open /dev/snd/seq failed: No such file or directory
[ERROR ] ledfx.integrations.midi : Unable to enumerate midi devices: MidiInAlsa::initialize: error creating ALSA sequencer client object.
ALSA lib seq_hw.c:466:(snd_seq_hw_open) open /dev/snd/seq failed: No such file or directory

Can someone explain me what I'm missing or having incorrectly configured?

Thanks

Hi,

First of all, thank you for creating this project. It's awesome and I managed to get it up and running fairly quickly. This is not really an issue, but more of a post with questions.

On the official page of https://ledfx.readthedocs.io/en/latest/installing.html#raspberry-pi-installation, they say I need a USB audio card for a raspberry pi.
I am actually running your container on raspberry pi 3 and it works with the built-in audio card. Is the main reason for this that you integrated snapcast into this repository and did some magic to direct the audio to LedFx with use of snapcast (basically the 50 hours of work you mention in the README :))? I haven't tried just running LedFx without your container so I'm not sure if USB audio card is necessary there too, but I assume yes given the documentation.

If the answer to the above is yes, then I'm curious if your work would ever be upstreamed to LedFx to make it work on a stock RPi without extra audio cards. Don't get me wrong, I support your project, but it would be even better if it was used in the original LedFx for the sake of simplicity and lower maintenance.

No call for action here, mere curiosity. Thank you again for this amazing contribution.
