1 Release notes for GStreamer Base Plugins 1.0.0
3 The GStreamer project is pleased to announce the very first release of the
4 new API and ABI-stable 1.x series of the GStreamer multimedia framework.
6 The 1.x series is a stable series targeted at end users. It is not API or ABI
7 compatible with the 0.10.x series. It can, however, be installed in parallel
8 with the 0.10.x series and will not affect an existing 0.10.x installation.
10 Major improvements include: more flexible memory handling; extensible and
11 negotiable metadata for buffers; caps negotiation and renegotiation mechanisms,
12 decoupled from buffer allocation; improved caps renegotiation; automatic
13 re-sending of state for dynamic pipelines; reworked and more fine-grained pad
14 probing; simpler and more descriptive audio and video caps; more efficient
15 allocation of buffers, events and other mini objects; improved timestamp
16 handling; support for gobject-inspection-based language bindings; countless
19 Most of these changes involve the GStreamer plugin API. The application API
20 has changed comparatively little, and most applications should be fairly easy
21 to port to the new API. There is a porting guide available.
23 The GStreamer team would like to thank everyone who helped bring this release
24 about, whether by submitting patches, reporting bugs, testing, sponsoring
25 development, attending hackfests, or simply supplying moral support.
27 This is the end of a long development process, but also the beginning of
28 one. This release does not mark the pinnacle of perfection, but the point
29 where the team is content with the API and stability and quality of the code
30 base in general, especially compared to the old 0.10 series.
32 There will be bugs to fix, and starting from this release there will be
33 distinct bug-fixing and feature development cycles, with the goal of getting
34 bug-fixes out quicker and unencumbered by other more risky changes. See
36 http://gstreamer.freedesktop.org/wiki/ReleasePlanning/RoadMap
38 for a tentative road map and possible schedule.
42 This module contains a set of reference plugins, base classes for other
43 plugins, and helper libraries.
45 This module is kept up-to-date together with the core developments.
46 Element writers should look at the elements in this module as a reference
47 for their development.
