Release notes for GStreamer 0.10.36 "Harder"
The GStreamer team is proud to announce a new release
in the 0.10.x stable series of the
core of the GStreamer streaming media framework.
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.
The 0.10.x series has been reworked for threadsafety. It also features
various feature additions and enhancements.
This module, gstreamer, only contains core functionality.
For actual media playback, you will need other modules.
gst-plugins-base
contains a basic set of well-supported plug-ins
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
* bin: Don't interpret pipelines without sink elements as always being in EOS state
* bin: Only post EOS messages after reaching the PLAYING state
* buffer: add set/get_qdata() to attach arbitrary metadata to buffers
* caps, structure, gstvalue: some optimisations and improvements
* miniobject: add weak referencing functionality
* gstobject: make gst_object_replace() atomic
* pad: Only do the subset check in gst_pad_accept_caps() if the pad claims to accept the caps
* pad: make public some ghostpad/proxypad API
* preset: allow applications to specify an extra preset directory with application-specific presets
* collectpads: add GstCollectPads2 API
* basebarse: new detect vfunc so subclassed can do some format detection first
* baseparse: new get_sink_caps vfunc so downstream caps restrictions can be propagated upstream
* baseparse: answer position query in stream time and try upstream first
* baseparse: send duration message when updating internal duration
* baseparse: make baseparse-based elements is reusable
* baseparse: provide latency query support
* basesink: don't compensate for render-delay twice

* filesrc/fdsrc: indicate dynamic size handling to basesrc
* inputselector: add sync mode that syncs inactive pads to the running time of the active pad
* queue2: add bufferlist support
* queue2: adjust input data rate estimation
* multiqueue: add mode to synchronize deactivated/not-linked streams by the running time
* multiqueue: check filled state of queues even if another one is empty
* outputselector: don't send last segment/buffer when no segment was configured yet
* tools: teach gst-launch about missing-plugin messages
* tools: make unversioned wrapper look for -0.10 tools only
