Release notes for
GStreamer Base Plugins 1.0.6
The GStreamer team is pleased to announce a new bug-fix release
in the 1.x stable series of the
core of the GStreamer streaming media framework.
The 1.x series is a stable series targeted at end users.
It is not API or ABI compatible with the stable 0.10.x series.
It is, however, parallel installable with the 0.10.x series and
will not affect an existing 0.10.x installation.
This module contains a set of reference plugins, base classes for other
plugins, and helper libraries. It also includes essential elements such
as audio and video format converters, and higher-level components like playbin,
