The process involves quite a few steps.
There’s a lot of dependencies that need to be satisfied. Fortunately, most of the dependencies are present in the Raspbian repositories; some (or all) may already be present on your system. I also need to download and install packages for libfdk-aac1 and libfdk-aac which are Fraunhofer FDK AAC Codec Libraries.
Next, clone the project’s GitHub repository, compile the source code, and install the program. Here’s the specific commands:
$ sudo apt-get --allow-releaseinfo-change update
$ sudo DEBIAN_FRONTEND=noninteractive apt-get -y dist-upgrade
$ sudo apt-get -y install build-essential checkinstall cmake git libmbedtls-dev libasound2-dev libavcodec-dev libavdevice-dev libavfilter-dev libavformat-dev libavutil-dev libcurl4-openssl-dev libfontconfig1-dev libfreetype6-dev libgl1-mesa-dev libjack-jackd2-dev libjansson-dev libluajit-5.1-dev libpulse-dev libqt5x11extras5-dev libspeexdsp-dev libswresample-dev libswscale-dev libudev-dev libv4l-dev libvlc-dev libx11-dev libx11-xcb1 libx11-xcb-dev libxcb-xinput0 libxcb-xinput-dev libxcb-randr0 libxcb-randr0-dev libxcb-xfixes0 libxcb-xfixes0-dev libx264-dev libxcb-shm0-dev libxcb-xinerama0-dev libxcomposite-dev libxinerama-dev pkg-config python3-dev qtbase5-dev libqt5svg5-dev swig
$ sudo wget https://ftp.uk.debian.org/debian/pool/non-free/f/fdk-aac/libfdk-aac1_0.1.4-2+b1_armhf.deb
$ sudo wget https://ftp.uk.debian.org/debian/pool/non-free/f/fdk-aac/libfdk-aac-dev_0.1.4-2+b1_armhf.deb
$ sudo dpkg -i libfdk-aac1_0.1.4-2+b1_armhf.deb
$ sudo dpkg -i libfdk-aac-dev_0.1.4-2+b1_armhf.deb
$ sudo git clone --recursive https://github.com/obsproject/obs-studio.git
$ cd obs-studio
$ sudo mkdir build && cd build
$ sudo cmake -DUNIX_STRUCTURE=1 -DCMAKE_INSTALL_PREFIX=/usr ..
$ sudo make -j4
$ sudo make install
I don’t take the credit for these steps. The process was detailed by TheMindVirus published on the obsproject forum.
Compiling the source code took 8 minutes 50 seconds (using all 4 cores of the RPI4). Make sure you use the argument -j4 with make, else the compile time will take a lot longer.
If you start obs from the newly-created menu entry or from the command-line, you get the following error.
Instead, launch the program with the command:
OBS Studio has a very useful auto-configuration wizard which starts when you load the program for the first time. This wizard automatically tests the system and seeks to find settings that your machine can handle. This includes streaming or recording, resolution, bitrate, encoder, streaming provider and more.
Here’s what the wizard determines for the RPI4.
As you can see, the wizard doesn’t recommend recording at 1080p. Instead, it recommends an output resolution of 853×480.
