Introduction to GStreamer Base Plug-ins

The GStreamer Base Plug-ins is a well-groomed and well-maintained collection of GStreamer plug-ins and elements, spanning the range of possible types of elements one would want to write for GStreamer. You will need at least one of Good, Bad, Ugly or Libav plugins for GStreamer applications to function properly.

Package Information

GStreamer Base Plug-ins Dependencies

Required

gstreamer-1.24.9 and Meson Toolchain Files (for lib32)

Recommended

alsa-lib-1.2.13, CDParanoia-III (for building the CDDA plugin), GLib-2.82.2 (with GObject Introspection), ISO Codes, libgudev, libjpeg-turbo, libogg-1.3.5, libpng-1.6.44, libvorbis-1.3.7, Mesa-24.2.7, Pango, wayland-protocols-1.38, and Xorg Libraries

Optional

graphene, GTK+-3 (for examples), Opus-1.5.2, Qt-5, SDL2-2.30.9, Valgrind, hotdoc, libtheora, libvisual, Orc, and Tremor

Installation of GStreamer Base Plug-ins

[Note]

Note

If you need a plugin for a given dependency, that dependency needs to be installed before this package.

Install GStreamer Base Plug-ins by running the following commands: 

mkdir build &&
cd    build &&

meson setup ..               \
      --prefix=/usr          \
      --buildtype=release    \
      --wrap-mode=nodownload &&

ninja

To test the results, issue: ninja test. The tests require an X terminal running, or all of the GL tests will fail. Five tests may produce timeouts on some systems depending on their graphics hardware and speed. One test, elements_appsrc, is known to fail on some systems.

Now, as the root user: 

ninja install

32-bit Installation of GStreamer Base Plug-ins

First clean the build directory 

rm -rf *

Install lib32 GStreamer Base Plug-ins by running the following commands: 

meson setup ..               \
      --cross-file lib32     \
      --prefix=/usr          \
      --libdir=/usr/lib32    \
      --buildtype=release    \
      --wrap-mode=nodownload \
      -D qt5=disabled &&

ninja

Now, as the root user: 

DESTDIR=$PWD/DESTDIR ninja install    &&
cp -vR DESTDIR/usr/lib32/* /usr/lib32 &&
rm -rf DESTDIR                        &&
ldconfig

Command Explanations

--buildtype=release: Specify a buildtype suitable for stable releases of the package, as the default may produce unoptimized binaries.

--wrap-mode=nodownload: This switch prevents meson from downloading any optional dependency which is not installed on the system.

-D qt5=disabled: This option disables QT5 support to prevent Meson from using the QT5 libraries for the 32-bit build if the libraries are found as they are likely 64-bit only if you have followed BLFS.
