gstreamer1.0-plugins-bad-apps - 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.

This package contains helper programs from the "bad" set, 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.
