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.

[Note]

Note

Development versions of BLFS may not build or run some packages properly if LFS or dependencies have been updated since the most recent stable versions of the books.

Package Information

GStreamer Base Plug-ins Dependencies

Required

gstreamer-1.24.8

Recommended

alsa-lib-1.2.12, CDParanoia-III-10.2 (for building the CDDA plugin), GLib-2.82.2 (with GObject Introspection), ISO Codes-4.17.0, libgudev-238, libjpeg-turbo-3.0.1, libogg-1.3.5, libpng-1.6.44, libvorbis-1.3.7, Mesa-24.2.5, Pango-1.54.0, wayland-protocols-1.38, and Xorg Libraries

Optional

graphene-1.10.8, GTK+-3.24.43 (for examples), Opus-1.5.2, SDL2-2.30.8, Valgrind-3.23.0, 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.

[Note]

Note

When installing, the build process does some additional linking. If you do not have Xorg in /usr, the LIBRARY_PATH variable needs to be defined for the root user. If using sudo to assume root, use the -E option to pass your current environment variables for the install process.

Now, as the root user: 

ninja install

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.
