Building GStreamer from Source on macOS with MacPorts

MacPorts does not currently supply an up-to-date GStreamer.

GStreamer 1.22.0 (just released) has been successfully built from source on MacPorts 2.8.1:

• install the build system:

sudo port install meson ninja bison flex cmake git pkgconfig

• Install some of the external libraries used by GStreamer:

sudo port install glib2-upstream ffmpeg-upstream pango graphene libvorbis libogg libopus libdv libjpeg-turbo 

• On MacPorts, it is also important to do

export LIBRARY_PATH=/opt/local/lib:$LIBRARY_PATH

before compiling, because MacPorts has modified symbols in libiconv, and you must prevent the macOS version of libiconv in /usr/lib from being used. (This leads to build failures with the error "_iconv not found".)

• now download GStreamer, build and install (this assumes v1.22.0; modify as needed, method is valid for 1.19.0 and later). This installs GStreamer in /usr/local/lib.

git clone https://gitlab.freedesktop.org/gstreamer/gstreamer
cd gstreamer
git checkout 1.22.0
