GPAC build MP4Box only all platforms
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.
We published a minimal solution to build MP4Box.exe only, with zero dependency. No DLL to distribute.
You need Visual Studio 2010 or more recent (a pop-up will ask you to upgrade your projects, just accept). Open build/msvc10/gpac_mp4box_mini.sln and build (Debug or Release).
That's all!
On your system, you need the following tools installed on your system:
- git
- gcc
- make
- libpthread-dev (should be available on any development system)
In your favorite terminal, type:
git clone https://github.com/gpac/gpac.git
cd gpac
./configure --static-mp4box --use-zlib=no
make -j4
Note
--use-zlib is optional, specify it only if you don't want support for zlib (compressed boxes, compressed files, ...).
To execute MP4Box, assuming you are still in the same directory (i.e. the root of the GPAC repository), you will find the MP4Box executable at:
bin/gcc/MP4Box
To install MP4Box on your system:
sudo make install
now when you type
which MP4Box
you should see
/usr/local/bin/MP4Box
which is the default install folder for the version we have just built. You can tweak this with the -prefix= configure option.
If you see /usr/bin/MP4Box (no "local/" in here), uninstall GPAC from your local packager. On MacOS, go to Finder and unmount the app on the left panel, or uninstall it from your package manager ('port' or 'homebrew' or 'fink').
Of course you want to keep updated with the latest build without having to download the full repository again or re-execute the configuration when not necessary (it may be necessary sometimes, see below "Clean your build" if things go unexpectedly):
cd gpac
git pull
make -j4
sudo make install
That's all!
If things go wrong and you suspect there is an issue in your configuration, the fastest way to restart a clean build is:
cd gpac
make distclean
./configure --static-mp4box --use-zlib=no
make -j4
Cross-compiling GPAC is quite standard, and requires only a modification at the 'configure' step. Use --extra-cflags= and --extra-ldflags= to add your environment flags:
cd gpac
./configure --target-os=$OS --cross-prefix="$crossPrefix" --extra-cflags="-I$PREFIX/$host/include" --extra-ldflags="-L$PREFIX/$host/lib" --prefix=$PREFIX/$host --static-mp4box --use-zlib=no
make -j4
For example, to use the 'x86_64-w64-mingw32' toolchain to cross-build from Linux to Windows:
cd gpac
./configure --target-os=mingw32 --cross-prefix=x86_64-w64-mingw32- --prefix=build/x86_64-w64-mingw32 --static-mp4box --use-zlib=no --extra-cflags="-Ibuild/x86_64-w64-mingw32/include" --extra-ldflags="-Lbuild/x86_64-w64-mingw32/lib"
make -j4
You can find more examples in our TravisCI script.
We have started a multimedia component-level build system called Zenbuild. Zenbuild builds FFmpeg/libav, VLC or GPAC with most of their features enabled (librtmp, jack, openHEVC, etc.). You can start using Zenbuild, it is fully operational!
