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 12.4 platform.

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.

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

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

To Build the package, issue: 

ninja -C build
[Note]

Note

Several tests need a terminal emulator in a graphical session. If 'gst10-plugins-good' is not installed, two tests, elements_rtpsrc and elements_rtpsink, will fail. To test the results, issue: 

ninja -C build

Now Install the package, as the root user: 

ninja -C build install

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.
