libgstreamer-plugins-bad1.0-dev - 1.18.4-3+deb11u4pureos1 main

GStreamer is a streaming media framework, based on graphs of filters
which operate on media data. Applications using this library can do
anything from real-time sound processing to playing videos, and just
about anything else media-related. Its plugin-based architecture means
that new data types or processing capabilities can be added simply by
installing new plug-ins.

GStreamer Bad Plug-ins is 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 contains development files for GStreamer libraries from the
"bad" set. The API is not guaranteed to be stable.
