Hi,

I would love some help to install OBS Studio on Trisquel 8. I followed the instructions in the attached photo and always end up with the following errors as seen below in Terminal.

andrew@andrew-ThinkPad-T400:~$ sudo apt-get update && sudo apt-get install obs-studio

The errors appear to be related to the ffmpeg-next ppa you have installed. Try removing or deselecting it in Control Center -> Software & Updates, and then run 'sudo apt update' again.

libfdk-aac0 looks proprietary at least because of that clause:

You may not charge copyright license fees for anyone to use, copy or distribute the FDK AAC Codec software or your modifications thereto.
https://raw.githubusercontent.com/mstorsjo/fdk-aac/master/NOTICE

The obs-studio package depending on that proprietary codec, you cannot use it in freedom.

So I guess you are telling me that I am not able to run OBS studio. Is there any similar lunix app that you would recommend?

> So I guess you are telling me that I am not able to run OBS studio.

OBS Studio has libfdk-aac0, which is a proprietary package, as a required dependency. However, the only purpose of this package is to support the AAC audio format. There are other, freer formats than AAC such as Vorbis and Opus, so if OBS Studio supports such formats then it's likely that OBS Studio could still be useable without AAC support.

To try this, we'll need to download and modify the .deb package so that it no longer tries to install libfdk-aac0, and then install from that .deb file with dpkg instead of apt. This will require us to install dependencies manually, so first run

$ apt-depends obs-studio

This will print all dependencies of obs-studio. Install all of them except for libfdk-aac0.

Then, run

$ apt download obs-studio
$ tar x obs-studio*.deb
$ tar -xzf control.tar.gz
$ sed -e s/"libfdk-aac0 (>= 0.1.1), "//g -i control
$ tar -cvzf control.tar.gz control
$ ar rcs newpackage.deb debian-binary control.tar.gz data.tar.xz
$ sudo dpkg -i newpackage.deb

If it installs without any errors, run it and see if it works. If so, it might be worth contacting the developers and asking them to make libfdk-aac0 a "suggested" dependency instead of a "required" one. That would make it easier to install obs-studio while avoiding libfdk-aac0.

Thanks for your help! Unfortunately I tried running that first command and got this error:

andrew@andrew-ThinkPad-T400:~$ apt-depends obs-studio
No command 'apt-depends' found, did you mean:
Command 'apt-rdepends' from package 'apt-rdepends' (main)

@chaosmonk thank you for your help, I am still having difficulty with the command:

andrew@andrew-ThinkPad-T400:~$ apt depends obs-studio
E: No packages found

Does this mean I need to try installing the program again?

Thanks!

No, OBS is not available in the Trisquel repository. It wasn't in the Ubuntu 16.04 repo either. You need to download the source code and compile it (without AAC support).

Shouldn't 'apt depends' still have worked if they added the PPA correctly though?

Yes, this is is the correct way to do it if within OP's level of ability.

Hi onpon4,

Thank you for your help. I am a complete beginner to this community and I understand I need to download the source code. Could you send me the link I need to download? Also, could you send me instructions for how to compile the application without ACC support?

Thanks so much for everyones help. I am grateful.

I unfortunately haven't succeeded at compiling it, but the source code is here:

OBS will work without it, but you need to recompile it without AAC support.

I don't think that clause renders libfdk-aac proprietary. Note that it says "copyright license fees", not "fees of any kind". You're not allowed to charge "copyright license fees" with the GNU GPL either, because anyone you give a copy to is required to get full permission to use/modify/redistribute under the GNU GPL (without additional cost).

The reason libfdk-aac is in "non-free", from my understanding, is that the license is GPL-incompatible and the library is typically combined with FFmpeg, a GPL-licensed program. So the combination is not libre, i.e. the same sort of issue as ZFS:

You can get the source code with

$ sudo apt install git
$ git clone https://github.com/obsproject/obs-studio

This will copy the repository to your machine in a directory called 'obs-studio'. However, from browsing the source code it is not obvious to me how to disabled AAC support. Maybe someone more experienced than I am can help.

I have gotten around to actually testing my own instructions and can be more specific now.

$ sudo add-apt-repository ppa:obsproject/obs-studio
$ sudo apt update
$ sudo apt install libavcodec-ffmpeg56 libavdevice-ffmpeg56 libavformat-ffmpeg56 libavutil-ffmpeg54 libc6 libcurl3 libdbus-1-3 libfontconfig1 libfreetype6 libgcc1 libjack0 libluajit-5.1-2 libpulse0 libpython3.5 libqt5core5a libqt5gui5 libqt5gui5 libqt5widgets5 libqt5x11extras5 libspeexdsp1 libstdc++6 libswresample-ffmpeg1 libswscale-ffmpeg3 libudev1 libv4l-0 libx11-6 libx11-xcb1 libx264-148 libxcb-shm0 libxcb-xfixes0 libxcb-xinerama0 libxcb1 libxcomposite1 libxfixes3 zlib1g
$ apt download obs-studio
$ ar x obs-studio_22.0.2-0obsproject1~xenial_amd64.deb
$ tar -xzf control.tar.gz
$ sed -e s/"libfdk-aac0 (>= 0.1.1), "//g -i control
$ tar -cvzf control.tar.gz control
$ ar rcs newpackage.deb debian-binary control.tar.gz data.tar.xz
$ sudo dpkg -i newpackage.deb

I was then able to launch OBS. I don't have a webcam so I can't test whether it records video, but it appears to be receiving microphone input.

Building from source without AAC support would be the more correct way to do it, but this way won't take very long to test so I think it's worth trying.

Hi, thank you so much for these instructions.

I was successful until this line:

andrew@andrew-ThinkPad-T400:~$ ar x obs-studio_22.0.2-0obsproject1~xenial_amd64.deb

This gave me no results.

Did you get an error, or was there just no output printed to the terminal? If you didn't get an error, keep going. Nothing was supposed to be printed. All that command does is extract several files from the deb file to be used in later steps.

Okay, so I finished the install, updated software on the computer and the software shows up as an installed application, but when I click on it to launch it, I get this error. I attached the photo for details.

It sounds like the program installed successfully and you're now running into a separate hardware issue. Instead of launching the program by clicking on it, can you run it from a terminal with

$ obs

and copy (Ctrl+Shift+C) any errors printed to the terminal and paste them here? Often the information printed to the terminal is more specific than error messages in the graphical interface.

Can you also run

$ glxinfo | grep OpenGL

and copy/paste that output here. This will give us some information about your GPU.

OBS Studio requires OpenGL 3.2 or higher.[1] Based on the output you posted

it appears that you have OpenGL 2.1, which is the newset version that you can use with the GM45 Express Chipset.

Unfortunately, this means that your hardware is too old to run OBS Studio. Unless you have access to newer hardware, you will need to use another program.

I'm not too familiar with OBS Studio or what features it has, but supposedly these programs are similar.

I would try Kazam first because it can be easily installed[3] from the Trisquel repository.

Hi everyone,i hope you all are doing well.

yes i think kazam and simplescreenrecorder would be a good replacement until some one experienced gets his hands on obs with trisquel in mind ^^

install simplescreenrecorder :

sudo add-apt-repository ppa:maarten-baert/simplescreenrecorder
sudo apt-get update
sudo apt-get install simplescreenrecorder

additional : sudo apt-get install libavcodec-extra

(credits to websiteforstudents :D )
