| Release notes for GStreamer Base Plugins 1.9.1 |
| |
| The GStreamer team is pleased to announce the first release of the unstable |
| 1.9 release series. The 1.9 release series is adding new features on top of |
| the 1.0, 1.2, 1.4, 1.6 and 1.8 series and is part of the API and ABI-stable 1.x release |
| series of the GStreamer multimedia framework. The unstable 1.9 release series |
| will lead to the stable 1.10 release series in the next weeks. Any newly added |
| API can still change until that point. |
| |
| |
| Binaries for Android, iOS, Mac OS X and Windows will be provided in the next days. |
| |
| |
| |
| 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, |
| decodebin, encodebin, and discoverer. |
| |
| 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, giosrc |
| network: tcp |
| typefind functions |
| audio processing: audioconvert, adder, audiorate, audioresample, volume |
| visualisation: libvisual |
| video processing: videoconvert, videoscale |
| high-level components: playbin, uridecodebin, decodebin, encodebin, discoverer |
| libraries: app, audio, fft, pbutils, riff, rtp, rtsp, sdp, tag, video |
| |
| |
| Other modules containing plugins are: |
| |
| |
| gst-plugins-good |
| contains a set of well-supported plugins under our preferred license |
| gst-plugins-ugly |
| contains a set of well-supported plugins, but might pose problems for |
| distributors |
| gst-plugins-bad |
| contains a set of less supported plugins that haven't passed the |
| rigorous quality testing we expect, or are still missing documentation |
| and/or unit tests |
| gst-libav |
| contains a set of codecs plugins based on libav (formerly gst-ffmpeg) |
