what a pain, the doc’s first line to install dependencies tries to install gstreamer! I don’t want to install it, I just want to build it. talk about the chicken and the egg!

so here is what I did:
sudo apt-get install gtk-doc-tools liborc-0.4-0 liborc-0.4-dev libvorbis-dev libcdparanoia-dev libcdparanoia0 cdparanoia libvisual-0.4-0 libvisual-0.4-dev libvisual-0.4-plugins libvisual-projectm vorbis-tools vorbisgain libopus-dev libopus-doc libopus0 libopusfile-dev libopusfile0 libtheora-bin libtheora-dev libtheora-doc libflac++-dev libavc1394-dev libraw1394-dev libraw1394-tools libraw1394-doc libraw1394-tools libtag1-dev libtagc0-dev libwavpack-dev wavpack
and I did this:
sudo apt-get install libasound2-dev libavcodec-dev libavformat-dev libswscale-dev

but still no joy, so I admitted defeat and
sudo apt-get install libgstreamer1.0-0

and then the same crap with the plugins, gave up for now

revisited 12/21/2018
I gave up on not installing gstreamer from packages. So a gstreamer exists in /usr/local/bin and another one I copiled myself in /opt/gstreamer

apt-get install gstreamer1.0-0
apt-get install gstreamer1.0-plugins-good gstreamer1.0-plugins-base gstreamer1.0-plugins-ugly gstreamer1.0-plugins-bad

export PKG_CONFIG_PATH=/opt/gstreamer/lib/pkgconfig
./autogen.sh –prefix=/opt/gstreamer –enable-gtk-doc –enable-iso-codes –enable-orc
./autogen.sh –prefix=/opt/gstreamer –disable-gtk-doc
my version is shit, had to change /opt/gstreamer/lib/pkgconfig/gstreamer-1.0.pc
from
prefix=/opt/gstreamer
libexecdir=${exec_prefix}/libexec
exec_prefix=${prefix}
to
prefix=/opt/gstreamer
exec_prefix=${prefix}
libexecdir=${exec_prefix}/libexec
