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.

[Note]

Note

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

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  --prefix=/usr       \
       --buildtype=release \
       -Dgpl=enabled       \
       -Dpackage-origin=https://www.linuxfromscratch.org/blfs/view/svn/ \
       -Dpackage-name="GStreamer 1.20.3 BLFS" &&
ninja

To test the results, issue: ninja test. Several tests need a terminal emulator in a graphical session. One test, aesdesc is known to fail.

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.

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