Introduction
- The GStreamer Rust bindings and Rust plugins module are now
officially part of upstream GStreamer.
+- The GStreamer Editing Services gained a gesdemux element that allows
+ directly playing back serialized edit list with playbin or
+ (uri)decodebin
+
- Many performance improvements
- ccconverter: a closed caption converter that can convert between
different formats
-- line21decoder: extract line21 closed captions from SD video streams
+- line21encoder, line21decoder: inject/extract line21 closed captions
+ to/from SD video streams
- cc708overlay: decodes CEA 608/708 captions and overlays them on
video
- qtdemux and qtmux support CEA 608/708 Closed Caption tracks
-- mpegvideoparse extracts Closed Captions from MPEG-2 video streams
+- mpegvideoparse, h264parse extracts Closed Captions from MPEG-2/H.264
+ video streams
+
+- avviddec, avvidenc, x264enc got support for extracting/injecting
+ Closed Captions
- decklinkvideosink can output closed captions and decklinkvideosrc
can extract closed captions
or uridecodebin3 etc.
- New closed caption elements: cccombiner, ccextractor, ccconverter,
- line21decoder and cc708overlay (see above)
+ line21encoder, line21decoder and cc708overlay (see above)
- wpesrc: new source element acting as a Web Browser based on WebKit
WPE
- srtpdec, srtpenc: add support for MKIs which allow multiple keys to
be used with a single SRTP stream
+- srtpdec, srtpenc: add support for AES-GCM and also add support for
+ it in gst-rtsp-server and rtspsrc.
+
- The srt Secure Reliable Transport plugin has integrated server and
client elements srt{client,server}{src,sink} into one (srtsrc and
srtsink), since SRT connection mode can be changed by uri
"connector-properties" can be used to pass custom properties to the
DRM.
-- waylandsink has a "fullscreen" property now.
+- waylandsink has a "fullscreen" property now and supports the
+ XDG-Shell protocol.
+
+- decklinkvideosink, decklinkvideosrc support selecting between
+ half/full duplex
+
+- The vulkan plugin gained support for macOS and iOS via MoltenVK in
+ addition to the existing support for X11 and Wayland
+
+- imagefreeze has a new num-buffers property to limit the number of
+ buffers that are produced and to send an EOS event afterwards
+
+- webrtcbin has a new, introspectable get-transceiver signal in
+ addition to the old get-transceivers signal that couldn’t be used
+ from bindings
+
+- Support for per-element latency information was added to the latency
+ tracer
Plugin and library moves
- gst_audio_buffer_truncate() convenience function to truncate a raw
audio buffer
+- GstDiscoverer has support for caching the results of discovery in
+ the default cache directory. This can be enabled with the use-cache
+ property and is disabled by default.
+
+- GstMeta that are attached to GstBuffers are now always stored in the
+ order in which they were added.
+
+- Additional support for signalling ONVIF specific features were
+ added: the SEEK event can store a trickmode-interval now and support
+ for the Rate-Control and Frames RTSP headers was added to the RTSP
+ library.
+
Miscellaneous performance and memory optimisations
import DMABUF FDs and also directly pass the pixel format, relying
on the GPU to do the conversion.
+- The OpenGL library no longer restores the OpenGL viewport. This is a
+ performance optimization to not require performing multiple
+ expensive glGet*() function calls per frame. This affects any
+ application or plugin use of the following functions and objects:
+ - glcolorconvert library object (not the element)
+ - glviewconvert library object (not the element)
+ - gst_gl_framebuffer_draw_to_texture()
+ - custom GstGLWindow implementations
+
Tracing framework and debugging improvements
object. This is currently limited to pads for GstElements and
events for the pads. The output may look like this:
- (gdb) gst-print pad.object.parent
- GstMatroskaDemux (matroskademux0) {
- SinkPad (sink, pull) {
- }
- SrcPad (video_0, push) {

- }
-
- gst_structure_to_string() now serialises the actual value of
pointers when serialising GstStructures instead of claiming they’re
NULL. This makes debug logging in various places less confusing,
GStreamer VAAPI
-- this section will be filled in in due course
+- Support Wayland’s display for context sharing, so the application
+ can pass its own wl_display in order to be used for the VAAPI
+ display creation.
+
+- A lot of work to support new Intel hardware using media-driver as VA
+ backend.
+
+- For non-x86 devices, VAAPI display can instantiate, through DRM,
+ with no PCI bus. This enables the usage of libva-v4l2-request
+ driver.
+
+- Added support for XDG-shell protocol as wl_shell replacement which
+ is currently deprecated. This change add as dependency
+ wayland-protocol.
+
+- GstVaapiFilter, GstVaapiWindow, and GstVaapiDecoder classes now
+ inherit from GstObject, gaining all the GStreamer’s instrumentation
+ support.
+
+- The metadata now specifies the plugin as Hardware class.
+
+- H264 decoder is more stable with problematic streams.
+
+- In H265 decoder added support for profiles main-422-10 (P010_10LE),
+ main-444 (AYUV) and main-444-10 (Y410)
+
+- JPEG decoder handles dynamic resolution changes.
+
+- More specification adherence in H264 and H265 encoders.
GStreamer OMX
GStreamer Editing Services and NLE
-- this section will be filled in in due course
+- Added a gesdemux element, it is an auto pluggable element that
+ allows decoding edit list like files supported by GES
+
+- Added gessrc which wraps a GESTimeline as a standard source element
+ (implementing the ges protocol handler)
+
+- Added basic support for videorate::rate property potentially
+ allowing changing playback speed
+
+- Layer priority is now fully automatic and they should be moved with
+ the new ges_timeline_move_layer method, ges_layer_set_priority is
+ now deprecated.
+
+- Added a ges_timeline_element_get_layer_priority so we can simply get
+ all information about GESTimelineElement position in the timeline
+
+- GESVideoSource now auto orientates the images if it is defined in a
+ meta (overridable).
+
+- Added some PyGObject overrides to make the API more pythonic
+
+- The threading model has been made more explicit with safe guard to
+ make sure not thread safe APIs are not used from the wrong threads.
+ It is also now possible to properly handle in what thread the API
+ should be used.
+
+- Optimized GESClip and GESTrackElement creation
+
+- Added a way to compile out the old, unused and deprecated
+ GESPitiviFormatter
+
+- Re implemented the timeline editing API making it faster and making
+ the code much more maintainable
+
+- Simplified usage of nlecomposition outside GES by removing quirks in
+ it API usage and removing the need to treat it specially from an
+ application perspective.
+
+- ges-launch-1.0:
+
+ - Added support to add titles to the timeline
+ - Enhance the help auto generating it from the code
+
+- Deprecate ges_timeline_load_from_uri as loading the timeline should
+ be done through a project now
+
+- MANY leaks have been plugged and the unit testsuite is now “leak
+ free”
GStreamer validate
-- this section will be filled in in due course
+- Added an action type to verify the checksum of the sink last-sample
+
+- Added an include keyword to validate scenarios
+
+- Added the notion of variable in scenarios, with the set-vars keyword
+
+- Started adding support for “performance” like tests by allowing to
+ define the number of dropped buffers or the minimum buffer frequency
+ on a specific pad
+
+- Added a validateflow plugin which allows defining the data flow to
+ be seen on a particular pad and verifying that following runs match
+ the expectations
+
+- Added support for appsrc based test definition so we can instrument
+ the data pushed into the pipeline from scenarios
+
+- Added a mockdecryptor allowing adding tests with on encrypted files,
+ the element will potentially be instrumented with a validate
+ scenario
+
+- gst-validate-launcher:
+
+ - Cleaned up output
+
+ - Changed the default for “muting” tests as user doesn’t expect
+ hundreds of windows to show up when running the testsuite
+
+ - Fixed the outputted xunit files to be compatible with GitLab
+
+ - Added support to run tests on media files in push mode (using
+ pushfile://)
+
+ - Added support for running inside gst-build
+
+ - Added support for running ssim tests on rendered files
+
+ - Added a way to simply define tests on pipelines through a simple
+ .json file
+
+ - Added a python app to easily run python testsuite reusing all
+ the launcher features
+
+ - Added flatpak knowledge so we can print backtrace even when
+ running from within flatpak
+
+ - Added a way to automatically generated “known issues”
+ suppressions lines
+
+ - Added a way to rerun tests to check if they are flaky and added
+ a way to tolerate tests known to be flaky
+
+ - Add a way to output html log files

-Bugs fixed in 1.16
-
-- this section will be filled in in due course
-
-More than XXX bugs have been fixed during the development of 1.16.
-
-This list does not include issues that have been cherry-picked into the
-stable 1.16 branch and fixed there as well, all fixes that ended up in
-the 1.16 branch are also included in 1.16.
-
-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.
-
-
Stable 1.16 branch
After the 1.16.0 release there will be several 1.16.x bug-fix releases
1.16.0
-1.16.0 is scheduled to be released around January/February 2019.
+1.16.0 was released on 19 April 2019.
Known Issues
development of 1.17/1.18 will happen in the git master branch.
The plan for the 1.18 development cycle is yet to be confirmed, but it
-is expected that feature freeze will be around July 2019 followed by
-several 1.17 pre-releases and the new 1.18 stable release in
-August/September.
+is possible that the next cycle will be a short one in which case
+feature freeze would be perhaps around August 2019 with a new 1.18
+stable release in September.
1.18 will be backwards-compatible to the stable 1.16, 1.14, 1.12, 1.10,
1.8, 1.6, 1.4, 1.2 and 1.0 release series.
