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.



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.

User Notes:

Installation of GStreamer Bad Plug-ins



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.



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= \
       -Dpackage-name="GStreamer 1.20.2 BLFS" &&

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.

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


Installed Programs: gst-transcoder-1.0 and playout
