How to build GStreamer on Mac OS/X PPC

Goals:

1. Get GStreamer to stream a video on native OS/X GUI (i.e., no XWindows). (This page, well in the future)

2. Do this using the Python bindings. (GstreamerMacPython page)

3. Do this in combination with wxPython. (GstreamerMacwxPython? page)

4. Use the Dirac video codec. (SchrodingerMac? page)

The native OS/X audio/video plugins are in the CVS version of gst-plugins-good. Due to depedencies, this means we have to build the rest from CVS as well. I checked out on 2006/11/02. The patches may not work on other versions.

1. Install libogg, libogg-shlibs, libvorbis0, libvorbis0-shlibs, glib2 2.12.0 and bison >= 1.35 using fink

• I installed esound too; future will tell if it will be used

2. Download, build and install liboil (http://liboil.freedesktop.org/download/liboil-0.3.8.tar.gz)

• To use liboil > 0.3.8, you need this patch:

3. Download, build and install gstreamer from CVS:

cvs -d:pserver:anoncvs@anoncvs.freedesktop.org:/cvs/gstreamer co gstreamer
cd gstreamer
PKG_CONFIG_PATH=/usr/local/lib/pkgconfig ./autogen.sh
make
make install

4. Download, build and install gst-plugins-base from CVS:

cvs -d:pserver:anoncvs@anoncvs.freedesktop.org:/cvs/gstreamer co gst-plugins-base
cd gst-plugins-base
PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/sw/lib/pkgconfig ./autogen.sh
make
make install

5. Download, build and install gst-plugins-good from CVS:

cvs -d:pserver:anoncvs@anoncvs.freedesktop.org:/cvs/gstreamer co gst-plugins-good
cd gst-plugins-good

PKG_CONFIG_PATH=/usr/local/lib/pkgconfig ./autogen.sh
cd sys/osxaudio
make
make install

Now, audio works! To test, run:

gst-launch audiotestsrc ! audioconvert ! audioresample ! osxaudiosink

6. Download, build and install gst-ffmpeg from CVS:

cvs -d:pserver:anoncvs@anoncvs.freedesktop.org:/cvs/gstreamer co gst-ffmpeg
cd gst-ffmpeg
PKG_CONFIG_PATH=/usr/local/lib/pkgconfig ./autogen.sh
cd gst-libs/ext/ffmpeg
./configure --prefix=/usr/local --enable-maintainer-mode --enable-gtk-doc --disable-v4l --disable-audio-oss --disable-dv1394 --disable-vhook --disable-ffmpeg --disable-ffserver --disable-ffplay --disable-sdltest --enable-pp --cache-file=/dev/null --srcdir=. --disable-altivec
cd ../../..
make
make install

The manual ./configure is needed to disable AltiVec, because ffmpeg refuses to compile with it enabled.
