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.

This package is known to build and work properly using an LFS-11.1 platform.

Installation of GStreamer Bad Plug-ins

[Note]

Note

If you do not have an Objective-C compiler installed, the build system for this package will emit a warning about a failed sanity check. This is harmless, and it is safe to continue.

[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 \
       -Dpackage-origin=https://www.linuxfromscratch.org/blfs/view/svn/ \
       -Dpackage-name="GStreamer 1.20.0 BLFS" &&
ninja

To test the results, issue: ninja test. Several tests need a terminal emulator in a graphical session.

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.
