GPAC Build Guide for Linux
Warning
GPAC's wiki has moved to wiki.gpac.io.
This github wiki will no longer be updated.
You can contribute to GPAC's documentation here.
Preliminary notes: the following instructions will be based on Ubuntu and Debian. It should be easily applicable to other distributions, the only changes should be name of the packages to be installed, and the package manager used.
GPAC is a modular piece of software which depends on third-party libraries. During the build process it will try to detect and leverage the installed third-party libraries on your system. Here are the instructions to:
- build GPAC easily (recommended for most users) from what's available on your system,
- build a minimal 'MP4Box' and 'gpac' (only contains GPAC core features like muxing and streaming),
- build a complete GPAC by rebuilding all the dependencies manually.
We first need to install some building tools:
sudo apt install build-essential pkg-config g++ git cmake yasm
git clone https://github.com/gpac/gpac.git
cd gpac
./configure
make
To parallelize the build you can use the -j
option of Make.
git pull
make
If this fails, do make clean
.
If this fails again, reconfigure your GPAC with the same option as you previously did: ./configure --xxx ...
. You can find these options at the top of your config.mak or config.h files (located in the folder where you call the configure
script from).
If you are upgrading from a previous version (especially going from below 1.0.0 to 1.0.0+) you should run make uninstall ; make distclean
before running ./configure
.
You can either:
-
sudo make install
to install the binaries, - or use the
MP4Box
orgpac
binary ingpac_public/bin/gcc/
directly, - or move/copy it somewhere manually.
Install the development packages for the third-party libraries GPAC is able to leverage:
sudo apt install zlib1g-dev libfreetype6-dev libjpeg62-dev libpng-dev libmad0-dev libfaad-dev libogg-dev libvorbis-dev libtheora-dev liba52-0.7.4-dev libavcodec-dev libavformat-dev libavutil-dev libswscale-dev libavdevice-dev libnghttp2-dev libopenjp2-7-dev libcaca-dev libxv-dev x11proto-video-dev libgl1-mesa-dev libglu1-mesa-dev x11proto-gl-dev libxvidcore-dev libssl-dev libjack-jackd2-dev libasound2-dev libpulse-dev libsdl2-dev dvb-apps mesa-utils
This list should work on Ubuntu from 14.04 (trusty
) to at least 22.04 (jammy
).
If you use Debian instead of Ubuntu, replace libjpeg62-dev
with libjpeg62-turbo-dev
. It should work at least from Debian 9 (stretch
) to 12 (bookworm
).
[Also tested on archlinux-2022.02.01-x86_64 with the following: pacman -S zlib freetype2 libjpeg-turbo libpng libmad faad2 libogg libvorbis libtheora a52dec ffmpeg libxv mesa glu xvidcore openssl jack2 alsa-lib libpulse sdl2
]
Once the packages are installed, you can follow the general build instructions from the previous section.
This build is intended if you only need GPAC core features such as demuxing, muxing and streaming or if you need a static build.
To build only the MP4Box and gpac command line utilities, you need to:
- Install build tools
sudo apt install build-essential pkg-config git
- Install zlib
sudo apt install zlib1g-dev
- Get the code
git clone https://github.com/gpac/gpac.git gpac_public
cd gpac_public
- Build
If you are upgrading from a previous version (especially going from below 1.0.0 to 1.0.0+) you should run make uninstall ; make distclean
before running ./configure
.
./configure --static-bin
make
- Use
You can either:
-
sudo make install
to install the binaries, - or use the
MP4Box
orgpac
binary ingpac_public/bin/gcc/
directly, - or move/copy it somewhere manually.
In order to do a full build, we'll first have to handle the dependencies. On Linux, we try to rely on system dependencies (i.e. installable packages) as much as possible and only build the rest manually.
From now on, we'll call the base working directory <GPAC_ROOT_DIR>
.
- Get the code
<GPAC_ROOT_DIR>$ git clone https://github.com/gpac/gpac.git gpac_public
<GPAC_ROOT_DIR>$ git clone https://github.com/gpac/deps_unix
<GPAC_ROOT_DIR>$ cd deps_unix
<GPAC_ROOT_DIR>/deps_unix$ git submodule update --init --recursive --force --checkout
The convention of calling the main gpac repository gpac_public
here is quite important for some scripts. If you don't you'll have to adapt the scripts in deps_unix
.
- Build the dependencies
<GPAC_ROOT_DIR>/deps_unix$ ./build_all.sh linux
If all went well, you should see some libs have been copied over to the gpac repository. It should look something like this:
<GPAC_ROOT_DIR>/deps_unix$ ls -l ../gpac_public/extra_lib/lib/gcc/
total 11240

(contents and versions may differ depending on updates and deprecated features)
Now that all the set up is done, we can build gpac by simply doing:
<GPAC_ROOT_DIR>/gpac_public$ ./configure
<GPAC_ROOT_DIR>/gpac_public$ make
<GPAC_ROOT_DIR>/gpac_public$ sudo make install
[on Arch Linux, use ./configure --prefix=/usr
since Arch doesn't use /usr/local by default]
If you already have a gpac version installed, or if you have already built gpac in the same directory, especially going from a version below 1.0.0 to 1.0.0 and after, you should run
<GPAC_ROOT_DIR>/gpac_public$ make uninstall
<GPAC_ROOT_DIR>/gpac_public$ make distclean
before running ./configure
.
If you want to use GPAC for development (in your own code for example), you can use make install-lib
.
It will install the necessary libraries and header files. It will also install a gpac.pc
file for pkg-config
. With it you can easily build projects that use the gpac library with something like:
$ gcc -o example $(pkg-config --cflags gpac) example.c $(pkg-config --libs gpac)
To generate a .deb package, you can use make deb
.
You will probably have to install some packaging tools to run it:
sudo apt install fakeroot dpkg-dev devscripts debhelper ccache
