Introduction to GStreamer Bad Plug-ins

The GStreamer Bad Plug-ins package contains a set of plug-ins that aren't up to par compared to the rest. They might be close to being good quality, but they're missing something - be it a good code review, some documentation, a set of tests, a real live maintainer, or some actual wide use.

Package Information

GStreamer Bad Plug-ins Dependencies

Required

gst-plugins-base-1.24.9 and Meson Toolchain Files (for lib32)

Recommended

libdvdread, libdvdnav, libva-2.22.0, and SoundTouch

Optional

See BLFS' gst-plugins-bad for a full list of optional dependencies.

Installation of GStreamer Bad Plug-ins

[Note]

Note

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

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

mkdir build &&
cd    build &&

meson setup ..            \
      --prefix=/usr       \
      --buildtype=release \
      -D gpl=enabled &&

ninja

To test the results, issue: ninja test. Several tests need a terminal emulator in a graphical session. One test, elements_dash_mpd, is known to fail. If gst-plugins-good-1.24.9 is not installed, two tests, elements_rtpsrc and elements_rtpsink, will fail.

Now, as the root user: 

ninja install

Installation of GStreamer Bad Plug-ins

First clean the build directory: 

rm -rf *

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

meson setup ..            \
      --cross-file lib32  \
      --prefix=/usr       \
      --libdir=/usr/lib32 \
      --buildtype=release \
      -D gpl=enabled &&

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.

-D gpl=enabled: Without this switch, plugins with dependencies on (A)GPL licensed libraries are not built.
