cornrow's Issues

Problems with sound

Hi, first of all thank you for cornrow!

A few things (let me know if i should open more than one issue)

1. At least on my rpi 4 the install via apt is broken due to some dependencies (libavcodec58 i think), which are outdated.
2. When connecting via cronrow to my rpi4 i get an output (via snapcast), but its pitched higher and stuttering. I tried disableing BluetoothLE, but the problem remains.
3. I tried installing the EQ App to investigate if the EQ causes the problem with the higher pitch, but the app is not available for Android anymore. Is there a way to disable EQ completely in the conf?
4. Are there other codecs implementet?

Thank you in advance.

Control via python script

Hi,

It's possible to control via a python script? This is, to start/stop, and to just be discoverable when I click a button? This is to avoid random users to connect to BT, they should have to press a button first to pair...

Thanks a lot

no sound when connected

Bluetooth doesent want to connect on android using the app . it says connecting to the raspberry pi but it fails

terminate called after throwing an instance of 'std::out_of_range'

Hello, and thank you for cornrow! When it works it's works so well...

I'm using this on a raspberry 4b with Raspbian GNU/Linux 11 (bullseye) and streamed as a snapcast source.

The following shows the status of the service after it has been aborted. If I restart the service it works well.

I have 3 sources in my snapcast config: cornrow, mopidy, and pianobar (pandora). I can easily switch sources using home assistant and nodered and everything works as expected until the abort service error. I've tried connecting both airplay and BT at the same time, and while AP took precedence, the BT connection took over once AP was disconnected.

I am not currently able to define when the problem happens. If I can provide further detail please advise.

Cheers

Install on raspberry pi

hi,

I would like to install this bluetooth audio, but I can't.
I would like to install it on raspberry pi 3, with the latest install version of raspbianOS

Snapcast integration - output to ALSA loopback, FIFO, or STDOUT?

I'd love to be able to integrate this with Snapcast as it's the only Bluetooth audio daemon I've found that works reliably on a Raspberry Pi. Snapcast can read from multiple source types but I'm unclear how to redirect cornrow's output to any of them. Any pointers would be appreciated!

Unable to reconnect after client "forgets" the server device

I'm experiencing an edge case problem in reconnecting a client to the cornrow server.

Steps to reproduce:

1. connect client to cornrow bluetooth server. Observe that music playback works fine.
2. In the client, click "Forget This Device" in the bluetooth settings for the cornrow bluetooth server
3. In the client, attempt to connect to the cornrow bluetooth server again. Observe error message: "Pairing Unsuccessful. iPhone can no longer connect to <server name>. Forget this device and pair it again."
4. Even after telling the client to "Forget Device" again, we are still unable to connect to the server.

There is a workaround for this error:

1. On the server, run bluetoothctl remove XX:XX:XX:XX:XX:XX, specifying the client's address
2. The client should now be able to connect to the cornrow server again

Client details: iPhone 13 mini, iOS version 16.1.1
Server details: Raspberry Pi 3 Model A Plus Rev 1.0, Raspbian GNU/Linux 11 (bullseye)

Thanks for any insight you can provide!

missing dev dependecies

Hi..
I am installing the sw into my raspi.

In the installation guide some dependecies are missing and the dpkg-buildpackage noticed that.
The dependencies are: libboost-dev extra-cmake-modules qtconnectivity5-dev

Thank you for sharing the project!

Debian bookworm support?

hey hey
great project, thanks for sharing it.
it worked as bluetooth to snapcast solution like a charm, but after upgrading to debian 12 based raspbian it no longer does :/

/usr/bin/cornrowd: error while loading shared libraries: libmmal_core.so.0: cannot open shared object file: No such file or directory

i'm currently searching around but can only find some dropped mmal support e.g. here
raspberrypi/userland#688

also the paths in /opt/vc/ where it lied up until bullseye is gone.

currently trying to recompile it and see if it works, but also fighting, so i though maybe already somebody has hit this problem?
thanks!

Unmet dependency: libboost-system1.67 on bullseye

Thanks for this project, it seems nice!

I'm trying to install it from deb, on an Rpi 3B+, Raspbian 11 Bullseye, 5.10.63-v7+ kernel.

$ sudo apt install ./cornrowd_0.8.0_armhf.deb
[...]
The following packages have unmet dependencies:
 cornrowd : Depends: libboost-system1.67.0 but it is not installable

If I try to install manually libboost-system or libboost-system-dev it installs 1.74.

1.67 is not available in the bullseye repo, only 1.74: https://packages.debian.org/bullseye/libboost-system-dev

Should I build it manually, or can you update the build for bullseye? Thanks!

Unable to Connect Bluetooth Device On Raspbian Buster and Bullseye

I recently installed cornrow in order to set up a bluetooth integration for my snapserver instance. Snapserver runs on a Ubuntu 22 server and I have a raspberry which runs snapclient. I tried to install cornrow on this raspberry in order to enable bluetooth connectivity and send everything back to the snapserver via tcp. Installation was straightforward and Corocomo connects without issue.
However, when I try to actually connect a bluetooth device (e. g. Android phone) the connection is terminated after roughly 1 second. Journalctl registers the following error:

bluetoothd[473]: Endpoint replied with an error: org.freedesktop.DBus.Error.NoReply

This is on raspbian buster (cornrow 0.8.0). I tried on raspbian bullseye (using cornrow 0.8.1) as well. The error was similar:

Bluetooth is configured correctly as far as I can tell since playback using pulseaudio (which I installed for a test) worked without altering bluetooth settings.

Thanks in advance and regards

iPhone unable to control volume

Hi,

Successfully installed on RaspberryPi B3+. When my macbook is connected, I can change the volume with my macbook. However with my iPhone connected, changing the volume on the iPhone doesn't change the volume on the speaker.

Edit: same problem when i boot Windows on my macbook, volume doesn't change when it's changed in Windows.

Another thing, the speaker isn't discoverable automatically. Would it be possible to make it discoverable automatically when no device is connected?

Thanks in advance & best regards,
Jesper

Usage of non-SBC codecs

Is it possible to use another Codec than SBC, e.g. aptx?

There is a codecs option in cornrowd.conf. But I found no information on other supported codecs and no other codec IDs in the A2DB specification.

Thanks for the time you have invested in cornrowd. It works already great with SBC.

Is this, because I use a Raspberry Pi 1 and the .deb file was compiled for Raspberry Pi 2+?

rpi zero conection issues

I installed the newest version of cornrow on my Raspberry PI Zero running DietPI.
Everything works smoothly and I can see the Pi as bluetooth device. When I want to connect to
the raspi, the connection suddenly drops.

When monitoring on the pi with bluetoothctl I can see the device which wants to connect, but two second later the connection breaks down and bluetoothctl reports it.

Any hints how to resolve this?

Remove qtconnectivity5-dev dependency

Compiling on Alpine

I've compiled cornrow on Docker with an Alpine image, during this I found some issues addressed in the attached patch, also included the dockerfile builder. All tests have been on 0.8.1.

It basically boils down to a few issues

1. Use of "uint" in thirdparty/libcornrow/src/audio/Peq.cpp, assume size_t should be appropriate
2. Use of "uint" throughout cornrowd/src/config/Persistence.cpp, i typedef'ed it to "unsigned int"
3. Alpine uses an external lib for execinfo (not maintained and in disorder)
4. Use of __bswap_16 vs __bswap16 in thirdparty/libcornrow/src/audio/AlsaSink.cpp
5. Unused variable in thirdparty/libcornrow/src/loguru/loguru.cpp(530)

char buff[256] __attribute__((unused));

7. Missing library in thirdparty/qtzeroprops/thirdparty/QtZeroConf/CMakeLists.txt, need avahi-common. This hit me in building (Docker) for debian bullseye as well.

   target_link_libraries(QtZeroConf PRIVATE avahi-client)
+  target_link_libraries(QtZeroConf PRIVATE avahi-common)

And that's about it, very nice and clean code :)

Now, the Alpine execinfo is in disorder and does core dump on calling backtrace.

pairing procedure

Hi again!
I am having issues pairing my Android phone. The app can control the gstreamer EQ but I cannot connect to the bluetooth in order to stream audio.

Is there any procedure or sequence to follow in order to have everything working (audio stream and EQ)?

Thank you again,
Roberto

Cannot connect with MacBook Pro

Hello, when I try to connect from my MacBook Pro the daemon crashes with following message:

Apologies for the crappy photo, the Pi was connected to my TV.

Good work by the way, it pretty well worked right after I installed the dependencies and the .deb package.

tested on Pi 4

Hi,

I setup cornrow on a Pi4 from the deb file.

• The I stream 48KHz audio to It with a scream service on a windows machine and it works. YESS.

But:

• I tried the android corocomo, but it do not detect anything (using Bluetooth I think)
• The Android application do not allow me to give the IP of my cornrowd server.
• The listen port can not be change (UDP 4010) and for me had been find using a netstat.
• I would like stream some linux sound to It, but I do not know what protocols is supported, what king of UDP data I should send.

Please add some doc / link to compatible software.
What is this software should be able of.
I do not have any STD error about Bluetooth at startup.

I started to looks for answer In sources, and I build time it's looks like libqt5websockets5-dev should in install on debian base OS

sudo apt-get install libqt5websockets5-dev

Can you add a not like 'do not forget to pull the git submodule' ?

Question: can I use it on OrangePi?

Hi! Thanks for this project!
I'm trying to figure out a cheap device as a scream output, it seams Orange Pi has all I need, an enteher port, a 16bit stereo ouput jack (with a cheap specific shield), a ready plastic box to contain it.. so that can be a good choice, does it work there? Thank you!

Configure Airplay or Bluetooth enabled

In my Snapcast server I've already configured an Airplay server, thus I would not need cornrow to create a new Airplay instance. Can it be possible to build without Airplay packages and disable it in the config file?

Issues building from source

Hi

I'm trying to build the latest version from source on Debian (bullseye) ,on an amd64 processor which is fully updated.
All the listed dependencies have been installed, and I've got the latest source (git clone --recursive https://github.com/mincequi/cornrow).

The build process fails with this error...

Any advice would be appreciated :)

Connection problems with smartphone

I've installed cornrow v0.9.0 with the deb file on my raspberry 4, but when I try connecting to it with bluetooth on my android smartphone I get constant audio stuttering or can't connect at all.

When the connection fails cornrow doesn't give me any logs. When it connects it shows something about a "broken pipe" the whole time, I would send the specific log message but I currently can't get my smartphone to connect.

Is there anything I can do to fix this, I never had problems with bluetooth headphones or similar.

I also tried connecting with my PC, that works without problems.
