Answer 3 · 2023-10-26T20:00:38.000Z

Woof thank. How did you install? It looks like something is wrong with the ffmpeg binding. Maybe recompile it. Also, is there a change you might have more than one copy of the ffmpeg libraries intalled on the system?

Answer 4 · 2023-10-26T20:15:10.000Z

Only ffmpeg/stable,now 8:5.1.3-1+rpt4 arm64 [installed]
I installed with apt. It worked afterward.
It only failed after the upgrades. This happens on DietPi Bookworm and Raspberry Pi OS Bookworm. There is another post to that effect on the Raspberry Pi OS forum.
These are somewhat recent updates.

It also fails on
liquidsoap-e1f7023_2.2.2-debian-bookworm-1_arm64.deb
I also tried liquidsoap_2.2.1-debian-bookworm-1_arm64.deb

----Steve

Answer 5 · 2023-10-26T20:33:55.000Z

Should I try to downgrade ffmpeg?
It was upgraded, but I didn't see in in the part of the list I looked at, so I missed it.
ffmpeg arm64 8:5.1.3-1+rpt4 [1795 kB]

Answer 6 · 2023-10-31T19:53:54.000Z

I installed liquidsoap 2.1.3-2 arm64 on a new DietPi Bookworm OS with apt-get using the supplied package.
It did not install, suggest or recommend ffmpeg. ffmpeg is not installed.
I still get the Segmentation fault.

Here is the gdb output from this installation:

Answer 7 · 2023-10-31T22:22:41.000Z

Thanks for these details. Our builds have switched to the debian multimedia ffmpeg packages to have builtin fdkaac. I suspect the segfault could be due to a ABI difference between the two.

Would you be able to install the ffmpeg package from https://deb-multimedia.org/ and try again?

Answer 8 · 2023-10-31T23:05:44.000Z

Is there a particular version I should try for Debian Bookworm?
Sometimes the package dependencies require specific versions.

Answer 9 · 2023-10-31T23:32:04.000Z

Does liqiudsoap require ffmpeg?
When I install the package, it does not install ffmpeg. It does not suggest or recommend ffmpeg.

On https://deb-multimedia.org/ I found ffmpeg (10:6.0-dmo6) - arm64 - Stable/bullseye
ffmpeg_4.4.4-dmo0+deb11u1_arm64.deb
I will try this one.

The package dependency versions are compatible with my Bullseye system.
The one listed for Bullseye uses newer dependencies.

Edit: there are no packages on https://deb-multimedia.org/ that work with my packages. ffmpeg_4.4.4-dmo0+deb11u1_arm64 is in theory compatible, but one of the required packages has dependency problems.

Answer 10 · 2023-11-01T02:45:14.000Z

With a Bookworm installed from an image from https://raspi.debian.net/tested-images/
These packages work:
liquidsoap 2.1.3-2 arm64
ffmpeg 7:5.1.3-1 arm64

DietPi Bookworm had
liquidsoap 2.1.3-2 arm64 (works on the Debian system above)
and
ffmpeg 8:5.1.3-1+rpt4 arm64
It faults with these packages.
I downgraded ffmpeg to:
ffmpeg 7:5.1.3-1 arm64
It still faults, with the same 2 packages as the Debian system.

On one DietPi system, I removed the ffmpeg package and installed it from source.
It still faults.

It looks to me like it's something other that ffmpeg.
liquidsoap faults on a system that has never had ffmpeg installed.
The same versions work on another system.
Installing ffmpeg from source does not work.
Another user reports the same problem on the Raspberry Pi forum
https://forums.raspberrypi.com/search.php?keywords=liquidsoap&sid=8ee93e3d44f03092738ed8e898e33156
There will be more.

The problem clearly happens after the latest large batch of package upgrades.

I could try installing liquidsoap from source, but that would be a big task.

Answer 11 · 2023-11-01T19:49:18.000Z

I was using ffmpeg as an easy way to talk about dependencies. In fact, yes, ffmpeg is not a dependency of liquidsoap but the various shared libraries that comes with it (libavformat, libavcodec, etc) are.

I'm gonna have to have a look at the packages themselves. The versions have different debian epoch (7 in 7:5.1.3-1 vs. 8 in 8:5.1.3-1+rpt4) which potentially indicates a different package.

Our goal with the binary packages we distribute is that they work with the standard packages of the regular distribution, here debian/bookworm.

If the derived distribution has custom packages that do not work with our binary build, I'm afraid we won't have enough development time to handle situations like that, in which case I would recommend building the binary yourself, indeed.

Answer 12 · 2023-11-01T20:07:02.000Z

I removed ffmpeg from the debian.net system and liquidsoap did run.
There are indeed big changes in the package versions. apt is saying:
Repository 'http://deb.debian.org/debian bookworm InRelease' changed its 'Version' value from '12.1' to '12.2'
Please let me know whether or not you have time to fix things. If not. I will attempt to build liquidsoap myself.

----Steve

Answer 13 · 2023-11-01T23:17:56.000Z

Hi @srs4511351,
So you are basically using a mix of different repositories?

Could you post a comprehensive list of the sources you use?
- cat /etc/apt/sources.list /etc/apt/sources.list.d/*.list /etc/apt/sources.list.d/*.sources > sources
- cat /etc/apt/preferences /etc/apt/preferences.d/* > preferences
  The result is stored in the sources and preferences files.
Could you post a list of installed packages?
- dpkg -l > packages
- apt list ?obsolete > obsolete
  The result will be stored in the packages and obsolete files.

Answer 14 · 2023-11-02T02:52:33.000Z

I am using the default sources that came with the OS.
Repository 'http://deb.debian.org/debian bookworm InRelease' changed its 'Version' value from '12.1' to '12.2'
Means that they changed repositories to a newer version.

I renamed the files to *.txt as files without an extension are not supported.

sources.txt
preferences.txt
packages.txt
obsolete.txt

Answer 15 · 2023-11-02T03:57:44.000Z

Hi @srs4511351. It's possible that the 2.1.3 build is outdate w.r.t. the latest ABI shipped by debian bookworm.

One thing you could try is install the latest build from https://github.com/savonet/liquidsoap/releases/tag/rolling-release-v2.2.x and see it this one works.

Answer 16 · 2023-11-02T04:19:54.000Z

Here's the one I tried.
sudo dpkg -i liquidsoap-3dc336b_2.2.2-debian-bookworm-1_arm64.deb

It installed with no dependency complaints.

dietpi@DietPi:~/Downloads$ /usr/bin/liquidsoap --version
Segmentation fault

Answer 17 · 2023-11-02T04:36:45.000Z

@toots,

liquidsoap is from https://packages.debian.org/bookworm/liquidsoap.
ffmpeg and libs are from https://archive.raspberrypi.org/debian/pool/main/f/ffmpeg/.

@srs4511351,
I'm curious if it's possible to use raspberry without deb https://archive.raspberrypi.org/debian/ bookworm main.

My idea is to:

Downgrade the versions of the libraries by pinning the deb.debian.org with priority 1000.
Keep liquidsoap from deb.debian.org and test if it crashes.
Try liquidsoap from the release artifacts.
Try deb https://www.deb-multimedia.org bookworm main non-free with liquidsoap from release artifacts.

The backup plan is to compile from opam.

Answer 18 · 2023-11-02T05:01:22.000Z

I think that deb https://archive.raspberrypi.org/debian/ bookworm main contains firmware, Raspberry Pi utilities, etc.
I could remove it from /etc/apt/sources.list.d/raspi.list if the existing firmware remains, but there would be no upgrades.

I do not know how to pin the deb.debian.org with priority 1000.
I can add deb https://www.deb-multimedia.org bookworm main non-free. Do I just add it to /etc/apt/sources.list, or do I need to remove the other lines in the file?

Then sudo apt update and sudo apt upgrade ?

I hope this is just a test. A permanent solution would be more transparent to the user.
Remember, it worked before the recent set of upgrades, so a downgrade may fix it.

I have a system installed from debian.net where liquidsoap works if you want to compare to that.

Answer 19 · 2023-11-02T05:12:43.000Z

@srs4511351, if tampering with packages makes the system unbootable, do you have a solution to restore the current state of the system?

Answer 20 · 2023-11-02T05:14:55.000Z

Yes, I have several other installations I can just swap in by changing the SD card.

I did a quick try...
renamed /etc/apt/sources.list.d/raspi.list
apt update/upgrade

The following packages will be upgraded:
libspeechd2 speech-dispatcher speech-dispatcher-audio-plugins
speech-dispatcher-espeak

liquidsoap

Answer 23 · 2023-11-02T05:50:42.000Z

So did this in effect remove the archive.raspberrypi.org/debian packages and use the debian ones?
Some were upgraded and MANY were downgraded.

liquidsoap no longer faults. I assume that this is restored to how it was before the recent upgrades.
If it is due to the raspberrypi.org packages, I would like for you to work with them to fix this properly.

Answer 24 · 2023-11-02T05:58:02.000Z

This is the state of current Debian without any changes introduced by a raspberry repo.
From this state I would like to continue testing with the liquidsoap from release artifacts and later deb-multimedia.

Answer 25 · 2023-11-02T05:59:20.000Z

OK, what do we do next?

Answer 26 · 2023-11-02T06:05:06.000Z

Download and install liquidsoap from the latest release artifact.
2.2.1 will also work.
Test it thoroughly to see if it works for you.

Add deb-multimedia.

wget https://www.deb-multimedia.org/pool/main/d/deb-multimedia-keyring/deb-multimedia-keyring_2016.8.1_all.deb
echo '9faa6f6cba80aeb69c9bac139b74a3d61596d4486e2458c2c65efe9e21ff3c7d  deb-multimedia-keyring_2016.8.1_all.deb' | sha256sum -c -

rm /etc/apt/preferences.d/debian.pref
apt-get update
apt-get dist-upgrade

Test liquidsoap.

Answer 27 · 2023-11-02T06:19:26.000Z

This is working for my application. It's op25, police scanner, used for compression and normalization.
I am hearing it on the same computer as the P25 scanner.

The raspberypi.org source is still disabled.

Answer 28 · 2023-11-02T06:25:54.000Z

Have you tested deb-multimedia?

The raspberypi.org source is still disabled.

I'm thinking about the smoothest way to enable it without breaking everything else.

Answer 29 · 2023-11-02T06:28:02.000Z

Yes, it is working after your instructions containing
echo 'deb https://www.deb-multimedia.org bookworm main non-free' > /etc/apt/sources.list.d/deb-multimedia.list

Answer 30 · 2023-11-02T06:47:10.000Z

How do I know if it is the one from deb-multimedia?
They all seem to be the same version...

Answer 31 · 2023-11-02T06:55:09.000Z

How do I know if it is the one from deb-multimedia?

dpkg --list | grep libavcodec
It should be some of libavcodec-4-dev, libavcodec-5-dev, libavcodec-dev, libavcodec58, libavcodec59, libavcodec60.

For example, there will be libavcodec59, then you check apt-cache policy libavcodec59.

Answer 33 · 2023-11-02T07:34:17.000Z

Does liquidsoap work with and without deb-multimedia?

If the answer is yes, then here's the first step of the plan:

apt-get purge --autoremove liquidsoap
mv /etc/apt/sources.list.d/deb-multimedia.list{,.backup}
apt-get update
apt list ?obsolete

Answer 34 · 2023-11-02T07:37:14.000Z

I removed liquidsoap and installed it again.
There was a line that said: Get:1 https://deb.debian.org/debian bookworm/main arm64 liquidsoap arm64 2.1.3-2
That isn't the one from deb-multimedia...

Answer 35 · 2023-11-02T07:52:29.000Z

Sorry, it's just the first step, the idea is to slowly introduce packages from raspberry.
My idea is to get rid of the packages from other sources and restore the original state, so it's possible to install packages in small groups.

apt-get purge --autoremove liquidsoap
mv /etc/apt/sources.list.d/deb-multimedia.list{,.backup}
apt-get update
apt list ?obsolete

Please paste the list of packages from the last command into this snippet. There's no need to install liquidsoap ahead of time.

Answer 36 · 2023-11-02T08:04:28.000Z

My point is that I made is that I may never have tried the package from deb-multimedia

The latest package from https://github.com/savonet/liquidsoap/releases/tag/rolling-release-v2.2.x
fails with my script. With the other package there was a deprecation message I think about the set command.

i’m in bed now. I will pick this up tomorrow.

Answer 48 · 2023-11-03T04:20:00.000Z

Looks strange, maybe something went wrong.
All raspberry packages are obsolete, looks like raspberry repository is missing.

echo 'deb https://archive.raspberrypi.org/debian/ bookworm main' > /etc/apt/sources.list.d/raspberrypi.list
apt-get update

Did you do this step?

Answer 49 · 2023-11-03T04:30:25.000Z

I did that step, which seems to be two commands, which is how the command line performed it.
/etc/apt/sources.list.d/raspberrypi.list is empty.
However, there was a backup file of the original /etc/apt/sources.list.d/raspi.list, which I have now restored.

Answer 59 · 2023-11-03T06:27:43.000Z

OK, and the last one is ffmpeg.

Let's try to upgrade.
Run apt-get dist-upgrade.
Check the liquidsoap.

To downgrade it back to the default version use the following settings
/etc/apt/preferences.d/ffmpeg.pref

Package: ffmpeg libavcodec-dev libavcodec59 libavdevice59 libavfilter8 libavformat-dev libavformat59 libavutil-dev libavutil57 libpostproc56 libswresample-dev libswresample4 libswscale-dev libswscale6
Pin: origin deb.debian.org
Pin-Priority: 1000

And then downgrade it as usual by using apt-get dist-upgrade.

I think if I pin it with a higher priority it will prevent any updates.
/etc/apt/preferences.d/ffmpeg.pref

Package: ffmpeg libavcodec-dev libavcodec59 libavdevice59 libavfilter8 libavformat-dev libavformat59 libavutil-dev libavutil57 libpostproc56 libswresample-dev libswresample4 libswscale-dev libswscale6
Pin: origin deb.debian.org
Pin-Priority: 600

Get the policy for ffmpeg apt-cache policy ffmpeg and check if it's apt list ?upgradable.

Answer 61 · 2023-11-03T07:02:59.000Z

So basically this is it, you can leave the system in this semi-upgraded state.
Just a final check.

mv /etc/apt/sources.list.d/deb-multimedia.list{.backup,};
apt-get update;
apt-cache policy ffmpeg;

The ultimate solution in this whole case would be to build liquidsoap from source.
On the plus side, this allows you to use custom dependencies and custom liquisoap versions.
But the downside is the requirement to maintain the ocaml itself and its packages. You also have to maintain compatibility with the system packages and rebuild the ocaml packages after any major changes.

The alternative solution would be to use a container from https://hub.docker.com/r/savonet/liquidsoap or build one yourself.
It works fine out of the box if you have no special hardware requirements.

Answer 62 · 2023-11-03T07:20:07.000Z

Wouldn’t it be easier to get Raspberry Pi to use compatible packages? Or maybe just the last pin to keep it from using the Raspberry Pi packages? It would have to be done before any of them are installed.
Otherwise I may as well do without liquidsoap.
Remember, others are having this problem and there will be more.

I will try your checks in the morning.

Answer 64 · 2023-11-03T23:55:56.000Z

I think the PATCH for ffmpeg in the raspberry pi repository makes it incompatible with the liquidsoap from the release artifacts and the bookworm repository.

Perhaps @toots will revisit this issue and suggest a better solution.

For now, my solutions to this problem are

Use ffmpeg from debian or deb-multimedia.
But you will lose the benefits of the patch, probably some hardware acceleration features.
Install liquidsoap from opam.
But you will have to maintain your ocaml installation.
Use containers.
But it'll be a problem if you plan to use some system/hardware features.

You can comment out the contents of the deb-multimedia.list.
Or if you'd like to clean up the remnants of deb-multimedia, then

rm /etc/apt/sources.list.d/deb-multimedia.list;
apt-get purge -y deb-multimedia-keyring;

Find and rm deb-multimedia-keyring_2016.8.1_all.deb.

I finally understand the workaround, I was just downgrading ffmpeg but not the other dependencies.

So I just downgrade ffmpeg and it's dependencies to the Debian version:

apt install ffmpeg=7:5.1.3-1
apt install libavcodec-dev=7:5.1.3-1 libavutil-dev=7:5.1.3-1 libswresample-dev=7:5.1.3-1 libswresample4=7:5.1.3-1 libavdevice-dev=7:5.1.3-1 libavfilter-dev=7:5.1.3-1 libavformat-dev=7:5.1.3-1 libswscale-dev=7:5.1.3-1 libavdevice59=7:5.1.3-1 libavfilter8=7:5.1.3-1 libpostproc-dev=7:5.1.3-1 libpostproc56=7:5.1.3-1 libavutil57=7:5.1.3-1 libswscale6=7:5.1.3-1 libavformat59=7:5.1.3-1 libavcodec59=7:5.1.3-1

Install Liquidsoap 2.2.2 dependencies:

apt install libao4 libfaad2 libfdk-aac2 liblo7 libmad0 libsdl2-image-2.0-0 libsdl2-ttf-2.0-0 libsoundtouch1 libtag1v5

And install it:

dpkg -i liquidsoap_2.2.2-debian-bookworm-1_arm64.deb

And it works!

I have found that on systems which do not yet have the ffmpeg suite installed, you can prevent the installation form the raspberry pi repository and liquidsoap will work. Raspberry Pi OS may have ffmpeg installed in the distributed image.

/etc/apt/preferences.d/ffmpeg.pref

Package: ffmpeg libavcodec-dev libavcodec59 libavdevice59 libavfilter8 libavformat-dev libavformat59 libavutil-dev libavutil57 libpostproc56 libswresample-dev libswresample4 libswscale-dev libswscale6
Pin: origin deb.debian.org
Pin-Priority: 600

If you look where this is presented above, it also shows how to downgrade it also. I haven't tried is on another system yet.

Edit: The procedure with ffmpeg.pref` previously presented fixes a Raspberry Pi OS system that already had the ffmpeg suite installed.

What can we do to resolve the root cause of this issue?
This issue removes out of the box apt installation of liquidsoap on raspberry pi's using bookworm.
@toots do you suggest we log this with ffmpeg support?

Beside the workaround, how can we get this fixed?

Hi @MediaMeasure,
There are a few ways to solve this problem.

You can build the liquidsoap from opam yourself.
This solution could be problematic for a person not familiar with opam and linux.
You can use containers.
This one has a lot of advantages, but for me the main culprit would be hardware acceleration and input/output device interaction.
There will be a special package for rpi.
This solution requires additional attention from the liquidsoap development team.

For anyone coming here looking for a solution, here's a workaround I came up with that combines and tweaks the suggestions above. It's not a good permanent solution, but it should work for now.

This process will work even if you've already installed liquidsoap and are getting the segfault.

Tested on a fresh install of RaspberryOS 12.5 with liquidsoap 2.1.3-2.

Create the /etc/apt/preferences.d/ffmpeg.pref file with the following contents:

Package: ffmpeg libavcodec-dev libavcodec59 libavdevice59 libavfilter8 libavformat-dev libavformat59 libavutil-dev libavutil57 libpostproc56 libswresample-dev libswresample4 libswscale-dev libswscale6
Pin: origin deb.debian.org
Pin-Priority: 1001

(This tells apt to only get these packages from the Debian repos, not the archive.raspberrypi.com repos. The priority of 1001 tells apt that we want it to downgrade packages, if needed.)

Run apt to downgrade (or install) the problematic packages:

apt install ffmpeg libswresample4 libavdevice59 libavfilter8 libpostproc56 libavutil57 libswscale6 libavformat59 libavcodec59

That's it. liquidsoap should run without segfaulting and you can run updates as normal.
