Release notes for GStreamer FFmpeg Plug-ins 0.10.12 "A year in hell"

The GStreamer team is proud to announce a new release in the 0.10.x stable series of the GStreamer FFmpeg Plug-ins.

The 0.10.x series is a stable series targeted at end users. It is not API or ABI compatible with the stable 0.8.x series. It is, however, parallel installable with the 0.8.x series.

This module contains plug-ins using libraries from the FFmpeg project.

Other modules containing plug-ins are:

contains a basic set of well-supported plug-ins
contains a set of well-supported plug-ins, but might pose problems for distributors
contains a set of less supported plug-ins that haven't passed the rigorous quality testing we expect
