GPAC: build MP4Box only (all platforms)

GPAC: build MP4Box only (all platforms)

29 July 2015 Compiling DASH, HEVC, MP4Box bouqueau

git clone https : //github.com/gpac/gpac.git cd gpac git pull . / configure -- static - mp4box -- use - zlib = no make - j4

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:

1

sudo make install

Check installation

now when you type

1

/ 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’).

Update to a newer revision

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 make distclean . / configure -- static - mp4box -- use - zlib = no make - j4

Cross-compilation

Cross-compiling GPAC is quite standard, and requires only a modification at the ‘configure’ step. Use ‘–extra-cflags=’ and ‘–extra-ldflags=’ to add your environmment flags:

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.

Next Step

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!
