| Release notes for GStreamer Base Plug-ins 0.10.30 "Difficult Birth" |
| |
| |
| |
| The GStreamer team is proud to announce a new release |
| in the 0.10.x stable series of the |
| GStreamer Base 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 a set of reference plugins, base classes for other |
| plugins, and helper libraries. |
| |
| This module is kept up-to-date together with the core developments. Element |
| writers should look at the elements in this module as a reference for |
| their development. |
| |
| This module contains elements for, among others: |
| |
| device plugins: x(v)imagesink, alsa, v4lsrc, cdparanoia |
| containers: ogg |
| codecs: vorbis, theora |
| text: textoverlay, subparse |
| sources: audiotestsrc, videotestsrc, gnomevfssrc, giosrc, appsrc |
| network: tcp |
| typefind functions |
| audio processing: audioconvert, adder, audiorate, audioresample, volume |
| visualisation: libvisual |
| video processing: ffmpegcolorspace |
| aggregate elements: uridecodebin, playbin2, decodebin2, decodebin, playbin |
| |
| |
| Other modules containing plug-ins are: |
| |
| |
| gst-plugins-good |
| contains a set of well-supported plug-ins under our preferred license |
| gst-plugins-ugly |
| contains a set of well-supported plug-ins, but might pose problems for |
| distributors |
| gst-plugins-bad |
| contains a set of less supported plug-ins that haven't passed the |
| rigorous quality testing we expect |
| |

| Features of this release |
| |
| * Use Orc (Optimized Inner Loops Runtime Compiler) for SIMD and |
| other optimisations, and remove liboil dependency. The main goal |
| for this release was to make the transition from liboil to liborc. |
| Performance improvements should not be expected and will be the |
| focus of future versions. liborc is an optional dependency for |
| the time being, to make it possible to test and develop the very |
| latest GStreamer versions on systems that don't have orc yet. |
| However, without orc slow unoptimised backup code will be used |
| for many performance critical code paths. Distributors are urged |
| to package and ship the latest version of liborc and compile |
| GStreamer modules with --enable-orc. Please do not distribute |
| GStreamer packages that are not orc enabled. More information on |
| the orc integration can be found in the docs/design/ directory. |
