- The default plugin entry point has changed. This will only affect
plugins that are recompiled against new GStreamer headers. Binary
plugins using the old entry point will continue to work. However,
plugins that are recompiled must have matching plugin names in
GST_PLUGIN_DEFINE and filenames, as the plugin entry point for
shared plugins is now deduced from the plugin filename. This means
you can no longer have a plugin called foo living in a file called
libfoobar.so or such, the plugin filename needs to match. This might
cause problems with some external third party plugin modules when
they get rebuilt against GStreamer 1.14.
Note to packagers and distributors
A number of libraries, APIs and plugins moved between modules and/or
libraries in different modules between version 1.12.x and 1.14.x, see
the _Plugin and_ _library moves_ section above. Some APIs have seen
minor ABI changes in the course of moving them into the stable APIs
section.
This means that you should try to ensure that all major GStreamer
modules are synced to the same major version (1.12 or 1.13/1.14) and can
only be upgraded in lockstep, so that your users never end up with a mix
of major versions on their system at the same time, as this may cause
breakages.
Also, plugins compiled against >= 1.14 headers will not load with
GStreamer <= 1.12 owing to a new plugin entry point (but plugin binaries
built against older GStreamer versions will continue to load with newer
versions of GStreamer of course).
There is also a small structure size related ABI breakage introduced in
the gst-plugins-bad codecparsers library between version 1.13.90 and
1.13.91. This should "only" affect gstreamer-vaapi, so anyone who ships
the release candidates is advised to upgrade those two modules at the
same time.

- The GStreamer wasapi plugin was rewritten and should not only be
usable now, but in top shape and suitable for low-latency use cases.
The Windows Audio Session API (WASAPI) is Microsoft's most modern
method for talking with audio devices, and now that the wasapi
plugin is up to scratch it is preferred over the directsound plugin.
The ranks of the wasapisink and wasapisrc elements have been updated
to reflect this. Further improvements include:
- support for more than 2 channels
- a new "low-latency" property to enable low-latency operation (which
should always be safe to enable)
- support for the AudioClient3 API which is only available on Windows
10: in wasapisink this will be used automatically if available; in
wasapisrc it will have to be enabled explicitly via the
"use-audioclient3" property, as capturing audio with low latency and
without glitches seems to require setting the realtime priority of
the entire pipeline to "critical", which cannot be done from inside
the element, but has to be done in the application.
- set realtime thread priority to avoid glitches
- allow opening devices in exclusive mode, which provides much lower
latency compared to shared mode where WASAPI's engine period is
10ms. This can be activated via the "exclusive" property.
- There are now GstDeviceProvider implementations for the wasapi and
directsound plugins, so it's now possible to discover both audio
sources and audio sinks on Windows via the GstDeviceMonitor API
- debug log timestamps are now higher granularity owing to
g_get_monotonic_time() now being used as fallback in
gst_utils_get_timestamp(). Before that, there would sometimes be
10-20 lines of debug log output sporting the same timestamp.

suggestions or helped testing.
More than 800 bugs have been fixed during the development of 1.14.
This list does not include issues that have been cherry-picked into the
stable 1.12 branch and fixed there as well, all fixes that ended up in
the 1.12 branch are also included in 1.14.
This list also does not include issues that have been fixed without a
bug report in bugzilla, so the actual number of fixes is much higher.
After the 1.14.0 release there will be several 1.14.x bug-fix releases
which will contain bug fixes which have been deemed suitable for a
stable branch, but no new features or intrusive changes will be added to
a bug-fix release usually. The 1.14.x bug-fix releases will be made from
the git 1.14 branch, which is a stable branch.
1.14.0 was released on 19 March 2018.
1.14.1
The first 1.14 bug-fix release (1.14.1) is scheduled to be released
around the end of March or beginning of April.
This release only contains bugfixes and it should be safe to update from
1.14.0.
- The webrtcdsp element (which is unrelated to the newly-landed
GStreamer webrtc support) is currently not shipped as part of the
Windows binary packages due to a build system issue.
Our next major feature release will be 1.16, and 1.15 will be the
unstable development version leading up to the stable 1.16 release. The
development of 1.15/1.16 will happen in the git master branch.
The plan for the 1.16 development cycle is yet to be confirmed, but it
is expected that feature freeze will be around August 2018 followed by
several 1.15 pre-releases and the new 1.16 stable release in September.
1.16 will be backwards-compatible to the stable 1.14, 1.12, 1.10, 1.8,
1.6, 1.4, 1.2 and 1.0 release series.
