+
+## Major new features and changes
+
+### Noteworthy new API, features and other changes
+
+#### Core API additions
+
+##### Receive property change notifications via bus messages
+
+New API was added to receive element property change notifications via
+bus messages. So far, applications had to connect a callback to an element's
+`notify::property-name` signal via the GObject API, which was inconvenient for
+at least two reasons: one had to implement a signal callback function, and that
+callback function would usually be called from one of the streaming threads, so
+one had to marshal (send) any information gathered or pending requests to the
+main application thread which was tedious and error-prone.
+
+Enter [`gst_element_add_property_notify_watch()`][notify-watch] and
+[`gst_element_add_property_deep_notify_watch()`][deep-notify-watch] which will
+watch for changes of a property on the specified element, either only for this
+element or recursively for a whole bin or pipeline. Whenever such a
+property change happens, a `GST_MESSAGE_PROPERTY_NOTIFY` message will be posted
+on the pipeline bus with details of the element, the property and the new
+property value, all of which can be retrieved later from the message in the
+application via [`gst_message_parse_property_notify()`][parse-notify]. Unlike
+the GstBus watch functions, this API does not rely on a running GLib main loop.
+
+The above can be used to be notified asynchronously of caps changes in the
+pipeline, or volume changes on an audio sink element, for example.
+
+[notify-watch]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/GstElement.html#gst-element-add-property-notify-watch
+[deep-notify-watch]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/GstElement.html#gst-element-add-property-deep-notify-watch
+[parse-notify]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/GstMessage.html#gst-message-parse-property-notify
+
+##### GstBin "deep" element-added and element-removed signals
+
+GstBin has gained `"deep-element-added"` and `"deep-element-removed"` signals
+which makes it easier for applications and higher-level plugins to track when
+elements are added or removed from a complex pipeline with multiple sub-bins.
+
+`playbin` makes use of this to implement the new `"element-setup"` signal which
+can be used to configure elements as they are added to `playbin`, just like the
+existing `"source-setup"` signal which can be used to configure the source
+element created.
+
+##### Error messages can contain additional structured details
+
+It is often useful to provide additional, structured information in error,
+warning or info messages for applications (or higher-level elements) to make
+intelligent decisions based on them. To allow this, error, warning and info
+messages now have API for adding arbitrary additional information to them
+using a `GstStructure`:
+[`GST_ELEMENT_ERROR_WITH_DETAILS`][element-error-with-details] and
+corresponding API for the other message types.
+
+This is now used e.g. by the new [`GST_ELEMENT_FLOW_ERROR`][element-flow-error]
+API to include the actual flow error in the error message, and the
+[souphttpsrc element][souphttpsrc-detailed-errors] to provide the HTTP
+status code, and the URL (if any) to which a redirection has happened.
+
+[element-error-with-details]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/GstElement.html#GST-ELEMENT-ERROR-WITH-DETAILS:CAPS
+[element-flow-error]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/GstElement.html#GST-ELEMENT-FLOW-ERROR:CAPS
+[souphttpsrc-detailed-errors]: https://cgit.freedesktop.org/gstreamer/gst-plugins-good/tree/ext/soup/gstsouphttpsrc.c?id=60d30db912a1aedd743e66b9dcd2e21d71fbb24f#n1318
+
+##### Redirect messages have official API now
+
+Sometimes, elements need to redirect the current stream URL and tell the
+application to proceed with this new URL, possibly using a different
+protocol too (thus changing the pipeline configuration). Until now, this was
+informally implemented using `ELEMENT` messages on the bus.
+
+Now this has been formalized in the form of a new `GST_MESSAGE_REDIRECT` message.
+A new redirect message can be created using [`gst_message_new_redirect()`][new-redirect].
+If needed, multiple redirect locations can be specified by calling
+[`gst_message_add_redirect_entry()`][add-redirect] to add further redirect
+entries, all with metadata, so the application can decide which is
+most suitable (e.g. depending on the bitrate tags).
+
+[new-redirect]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/GstMessage.html#gst-message-new-redirect
+[add-redirect]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/GstMessage.html#gst-message-add-redirect-entry
+
+##### New pad linking convenience functions that automatically create ghost pads
+
+New pad linking convenience functions were added:
+[`gst_pad_link_maybe_ghosting()`][pad-maybe-ghost] and
+[`gst_pad_link_maybe_ghosting_full()`][pad-maybe-ghost-full] which were
+previously internal to GStreamer have now been exposed for general use.
+
+The existing pad link functions will refuse to link pads or elements at
+different levels in the pipeline hierarchy, requiring the developer to
+create ghost pads where necessary. These new utility functions will
+automatically create ghostpads as needed when linking pads at different
+levels of the hierarchy (e.g. from an element inside a bin to one that's at
+the same level in the hierarchy as the bin, or in another bin).
+
+[pad-maybe-ghost]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/GstPad.html#gst-pad-link-maybe-ghosting
+[pad-maybe-ghost-full]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/GstPad.html#gst-pad-link-maybe-ghosting-full
+
+##### Miscellaneous
+
+Pad probes: IDLE and BLOCK probes now work slightly differently in pull mode,
+so that push and pull mode have opposite scenarios for idle and blocking probes.
+In push mode, it will block with some data type and IDLE won't have any data.
+In pull mode, it will block _before_ getting a buffer and will be IDLE once some
+data has been obtained. ([commit][commit-pad-probes], [bug][bug-pad-probes])
+
+[commit-pad-probes]: https://cgit.freedesktop.org/gstreamer/gstreamer/commit/gst/gstpad.c?id=368ee8a336d0c868d81fdace54b24431a8b48cbf
+[bug-pad-probes]: https://bugzilla.gnome.org/show_bug.cgi?id=761211
+
+[`gst_parse_launch_full()`][parse-launch-full] can now be made to return a
+`GstBin` instead of a top-level pipeline by passing the new
+`GST_PARSE_FLAG_PLACE_IN_BIN` flag.
+
+[parse-launch-full]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/gstreamer-GstParse.html#gst-parse-launch-full
+
+The default GStreamer debug log handler can now be removed before
+calling `gst_init()`, so that it will never get installed and won't be active
+during initialization.
+
+A new [`STREAM_GROUP_DONE` event][stream-group-done-event] was added. In some
+ways it works similar to the `EOS` event in that it can be used to unblock
+downstream elements which may be waiting for further data, such as for example
+`input-selector`. Unlike `EOS`, further data flow may happen after the
+`STREAM_GROUP_DONE` event though (and without the need to flush the pipeline).
+This is used to unblock input-selector when switching between streams in
+adaptive streaming scenarios (e.g. HLS).
+
+[stream-group-done-event]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/GstEvent.html#gst-event-new-stream-group-done
+
+The `gst-launch-1.0` command line tool will now print unescaped caps in verbose
+mode (enabled by the -v switch).
+
+[`gst_element_call_async()`][call-async] has been added as convenience API for
+plugin developers. It is useful for one-shot operations that need to be done
+from a thread other than the current streaming thread. It is backed by a
+thread-pool that is shared by all elements.
+
+[call-async]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/GstElement.html#gst-element-call-async
+
+Various race conditions have been fixed around the `GstPoll` API used by e.g.
+`GstBus` and `GstBufferPool`. Some of these manifested themselves primarily
+on Windows.
+
+`GstAdapter` can now keep track of discontinuities signalled via the `DISCONT`
+buffer flag, and has gained [new API][new-adapter-api] to track PTS, DTS and
+offset at the last discont. This is useful for plugins implementing advanced
+trick mode scenarios.
+
+[new-adapter-api]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer-libs/html/GstAdapter.html#gst-adapter-pts-at-discont
+
+`GstTestClock` gained a new [`"clock-type"` property][clock-type-prop].
+
+[clock-type-prop]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer-libs/html/GstTestClock.html#GstTestClock--clock-type
+
+#### GstStream API for stream announcement and stream selection
+
+New stream listing and stream selection API: new API has been added to
+provide high-level abstractions for streams ([`GstStream`][stream-api])
+and collections of streams ([`GstStreamCollections`][stream-collection-api]).
+
+##### Stream listing
+
+A [`GstStream`][stream-api] contains all the information pertinent to a stream,
+such as stream id, caps, tags, flags and stream type(s); it can represent a
+single elementary stream (e.g. audio, video, subtitles, etc.) or a container
+stream. This will depend on the context. In a decodebin3/playbin3 one
+it will typically be elementary streams that can be selected and unselected.
+
+A [`GstStreamCollection`][stream-collection-api] represents a group of streams
+and is used to announce or publish all available streams. A GstStreamCollection
+is immutable - once created it won't change. If the available streams change,
+e.g. because a new stream appeared or some streams disappeared, a new stream
+collection will be published. This new stream collection may contain streams
+from the previous collection if those streams persist, or completely new ones.
+Stream collections do not yet list all theoretically available streams,
+e.g. other available DVD angles or alternative resolutions/bitrate of the same
+stream in case of adaptive streaming.
+
+New events and messages have been added to notify or update other elements and
+the application about which streams are currently available and/or selected.
+This way, we can easily and seamlessly let the application know whenever the
+available streams change, as happens frequently with digital television streams
+for example. The new system is also more flexible. For example, it is now also
+possible for the application to select multiple streams of the same type
+(e.g. in a transcoding/transmuxing scenario).
+
+A [`STREAM_COLLECTION` message][stream-collection-msg] is posted on the bus
+to inform the parent bin (e.g. `playbin3`, `decodebin3`) and/or the application
+about what streams are available, so you no longer have to hunt for this
+information at different places. The available information includes number of
+streams of each type, caps, tags etc.  Bins and/or the application can intercept
+the message synchronously to select and deselect streams before any data is
+produced - for the case where elements such as the demuxers support the new
+stream API, not necessarily in the parsebin compatibility fallback case.
+
+Similarly, there is also a [`STREAM_COLLECTION` event][stream-collection-event]
+to inform downstream elements of the available streams. This event can be used
+by elements to aggregate streams from multiple inputs into one single collection.
+
+The `STREAM_START` event was extended so that it can also contain a GstStream
+object with all information about the current stream, see
+[`gst_event_set_stream()`][event-set-stream] and
+[`gst_event_parse_stream()`][event-parse-stream].
+[`gst_pad_get_stream()`][pad-get-stream] is a new utility function that can be
+used to look up the GstStream from the `STREAM_START` sticky event on a pad.

+[pad-get-stream]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/GstPad.html#gst-pad-get-stream
+
+##### Stream selection
+
+Once the available streams have been published, streams can be selected via
+their stream ID using the new `SELECT_STREAMS` event, which can be created
+with [`gst_event_new_select_streams()`][event-select-streams]. The new API
+supports selecting multiple streams per stream type. In the future, we may also
+implement explicit deselection of streams that will never be used, so
+elements can skip these and never expose them or output data for them in the
+first place.
+
+The application is then notified of the currently selected streams via the
+new `STREAMS_SELECTED` message on the pipeline bus, containing both the current
+stream collection as well as the selected streams. This might be posted in
+response to the application sending a `SELECT_STREAMS` event or when
+`decodebin3` or `playbin3` decide on the streams to be initially selected without
+application input.
+
+[event-select-streams]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/GstEvent.html#gst-event-new-select-streams
+
+##### Further reading

+
+#### Audio conversion and resampling API
+
+The audio conversion library received a completely new and rewritten audio
+resampler, complementing the audio conversion routines moved into the audio
+library in the [previous release][release-notes-1.8]. Integrating the resampler
+with the other audio conversion library allows us to implement generic
+conversion much more efficiently, as format conversion and resampling can now
+be done in the same processing loop instead of having to do it in separate
+steps (our element implementations do not make use of this yet though).
+
+The new audio resampler library is a combination of some of the best features
+of other samplers such as ffmpeg, speex and SRC. It natively supports S16, S32,
+F32 and F64 formats and uses optimized x86 and neon assembly for most of its
+processing. It also has support for dynamically changing sample rates by incrementally
+updating the filter tables using linear or cubic interpolation. According to
+some benchmarks, it's one of the fastest and most accurate resamplers around.
+
+The `audioresample` plugin has been ported to the new audio library functions
+to make use of the new resampler.
+
+[release-notes-1.8]: https://gstreamer.freedesktop.org/releases/1.8/
+
+#### Support for SMPTE timecodes
+
+Support for SMPTE timecodes was added to the GStreamer video library. This
+comes with an abstraction for timecodes, [`GstVideoTimeCode`][video-timecode]
+and a [`GstMeta`][video-timecode-meta] that can be placed on video buffers for
+carrying the timecode information for each frame. Additionally there is
+various API for making handling of timecodes easy and to do various
+calculations with them.
+
+A new plugin called [`timecode`][timecode-plugin] was added, that contains an
+element called `timecodestamper` for putting the timecode meta on video frames
+based on counting the frames and another element called `timecodewait` that
+drops all video (and audio) until a specific timecode is reached.
+
+Additionally support was added to the Decklink plugin for including the
+timecode information when sending video out or capturing it via SDI, the
+`qtmux` element is able to write timecode information into the MOV container,
+and the `timeoverlay` element can overlay timecodes on top of the video.
+
+More information can be found in the [talk about timecodes][timecode-talk] at
+the GStreamer Conference 2016.

+
+#### GStreamer OpenMAX IL plugin
+
+The last gst-omx release, 1.2.0, was in July 2014. It was about time to get
+a new one out with all the improvements that have happened in the meantime.
+From now on, we will try to release gst-omx together with all other modules.
+
+This release features a lot of bugfixes, improved support for the Raspberry Pi
+and in general improved support for zerocopy rendering via EGL and a few minor
+new features.
+
+At this point, gst-omx is known to work best on the Raspberry Pi platform but
+it is also known to work on various other platforms. Unfortunately, we are
+not including configurations for any other platforms, so if you happen to use
+gst-omx: please send us patches with your configuration and code changes!
+
+### New Elements
+
+#### decodebin3, playbin3, parsebin (experimental)
+
+This release features new decoding and playback elements as experimental
+technology previews: `decodebin3` and `playbin3` will soon supersede the
+existing `decodebin` and `playbin` elements. We skipped the number 2 because
+it was already used back in the 0.10 days, which might cause confusion.
+Experimental technology preview means that everything should work fine already,
+but we can't guarantee there won't be minor behavioural changes in the
+next cycle. In any case, please test and report any problems back.
+
+Before we go into detail about what these new elements improve, let's look at
+the new [`parsebin`][parsebin] element. It works similarly to `decodebin` and
+`decodebin3`, only that it stops one step short and does not plug any actual
+decoder elements. It will only plug parsers, tag readers, demuxers and
+depayloaders. Also note that parsebin does not contain any queueing element.
+
+[`decodebin3`'s][decodebin3] internal architecture is slightly different from
+the existing `decodebin` element and fixes many long-standing issues with our
+decoding engine. For one, data is now fed into the internal `multiqueue` element
+*after* it has been parsed and timestamped, which means that the `multiqueue`
+element now has more knowledge and is able to calculate the interleaving of the
+various streams, thus minimizing memory requirements and doing away with magic
+values for buffering limits that were conceived when videos were 240p or 360p.
+Anyone who has tried to play back 4k video streams with decodebin2
+will have noticed the limitations of that approach. The improved timestamp
+tracking also enables `multiqueue` to keep streams of the same type (audio,
+video) aligned better, making sure switching between streams of the same type
+is very fast.
+
+Another major improvement in `decodebin3` is that it will no longer decode
+streams that are not being used. With the old `decodebin` and `playbin`, when
+there were 8 audio streams we would always decode all 8 streams even
+if 7 were not actually used. This caused a lot of CPU overhead, which was
+particularly problematic on embedded devices. When switching between streams
+`decodebin3` will try hard to re-use existing decoders. This is useful when
+switching between multiple streams of the same type if they are encoded in the
+same format.
+
+Re-using decoders is also useful when the available streams change on the fly,
+as might happen with radio streams (chained Oggs), digital television
+broadcasts, when adaptive streaming streams change bitrate, or when switching
+gaplessly to the next title. In order to guarantee a seamless transition, the
+old `decodebin2` would plug a second decoder for the new stream while finishing
+up the old stream. With `decodebin3`, this is no longer needed - at least not
+when the new and old format are the same. This will be particularly useful
+on embedded systems where it is often not possible to run multiple decoders
+at the same time, or when tearing down and setting up decoders is fairly
+expensive.
+
+`decodebin3` also allows for multiple input streams, not just a single one.
+This will be useful, in the future, for gapless playback, or for feeding
+multiple external subtitle streams to decodebin/playbin.
+
+`playbin3` uses `decodebin3` internally, and will supercede `playbin`.
+It was decided that it would be too risky to make the old `playbin` use the
+new `decodebin3` in a backwards-compatible way. The new architecture
+makes it awkward, if not impossible, to maintain perfect backwards compatibility
+in some aspects, hence `playbin3` was born, and developers can migrate to the
+new element and new API at their own pace.
+
+All of these new elements make use of the new `GstStream` API for listing and
+selecting streams, as described above. `parsebin` provides backwards
+compatibility for demuxers and parsers which do not advertise their streams
+using the new API yet (which is most).
+
+The new elements are not entirely feature-complete yet: `playbin3` does not
+support so-called decodersinks yet where the data is not decoded inside
+GStreamer but passed directly for decoding to the sink. `decodebin3` is missing
+the various `autoplug-*` signals to influence which decoders get autoplugged
+in which order. We're looking to add back this functionality, but it will probably
+be in a different way, with a single unified signal and using GstStream perhaps.
+

+
+#### LV2 ported from 0.10 and switched from slv2 to lilv2
+
+The LV2 wrapper plugin has been ported to 1.0 and moved from using the
+deprecated slv2 library to its replacement liblv2. We support sources and
+filter elements. lv2 is short for *Linux Audio Developer's Simple Plugin API
+(LADSPA) version 2* and is an open standard for audio plugins which includes
+support for audio synthesis (generation), digital signal processing of digital
+audio, and MIDI. The new lv2 plugin supersedes the existing LADSPA plugin.
+
+#### WebRTC DSP Plugin for echo-cancellation, gain control and noise suppression
+
+A set of new elements ([webrtcdsp][webrtcdsp], [webrtcechoprobe][webrtcechoprobe])
+based on the WebRTC DSP software stack can now be used to improve your audio
+voice communication pipelines. They support echo cancellation, gain control,
+noise suppression and more. For more details you may read
+[Nicolas' blog post][webrtc-blog-post].

+
+#### Fraunhofer FDK AAC encoder and decoder
+
+New encoder and decoder elements wrapping the Fraunhofer FDK AAC library have
+been added (`fdkaacdec`, `fdkaacdec`). The Fraunhofer FDK AAC encoder is
+generally considered to be a very high-quality AAC encoder, but unfortunately
+it comes under a non-free license with the option to obtain a paid, commercial
+license.
+
+### Noteworthy element features and additions
+
+#### Major RTP and RTSP improvements
+
+- The RTSP server and source element, as well as the RTP jitterbuffer now support
+  remote clock synchronization according to [RFC7273][https://tools.ietf.org/html/rfc7273].
+- Support for application and profile specific RTCP packets was added.
+- The H265/HEVC payloader/depayloader is again in sync with the final RFC.
+- Seeking stability of the RTSP source and server was improved a lot and
+  runs stably now, even when doing scrub-seeking.
+- The RTSP server received various major bugfixes, including for regressions that
+  caused the IP/port address pool to not be considered, or NAT hole punching
+  to not work anymore. [Bugzilla #766612][https://bugzilla.gnome.org/show_bug.cgi?id=766612]
+- Various other bugfixes that improve the stability of RTP and RTSP, including
+  many new unit / integration tests.
+
+#### Improvements to splitmuxsrc and splitmuxsink
+
+- The splitmux element received reliability and error handling improvements,
+  removing at least one deadlock case. `splitmuxsrc` now stops cleanly at the end
+  of the segment when handling seeks with a stop time. We fixed a bug with large
+  amounts of downstream buffering causing incorrect out-of-sequence playback.
+
+- `splitmuxsrc` now has a `"format-location"` signal to directly specify the list
+  of files to play from.
+
+- `splitmuxsink` can now optionally send force-keyunit events to upstream
+  elements to allow splitting files more accurately instead of having to wait
+  for upstream to provide a new keyframe by itself.
+
+#### OpenGL/GLES improvements
+
+##### iOS and macOS (OS/X)
+
+- We now create OpenGL|ES 3.x contexts on iOS by default with a fallback to
+  OpenGL|ES 2.x if that fails.
+- Various zerocopy decoding fixes and enhancements with the
+  encoding/decoding/capturing elements.
+- libdispatch is now used on all Apple platforms instead of GMainLoop, removing
+  the expensive poll()/pthread_*() overhead.
+
+##### New API
+
+- `GstGLFramebuffer` - for wrapping OpenGL frame buffer objects.  It provides
+  facilities for attaching `GstGLMemory` objects to the necessary attachment
+  points, binding and unbinding and running a user-supplied function with the
+  framebuffer bound.
+- `GstGLRenderbuffer` (a `GstGLBaseMemory` subclass) - for wrapping OpenGL
+  render buffer objects that are typically used for depth/stencil buffers or
+  for color buffers where we don't care about the output.
+- `GstGLMemoryEGL` (a `GstGLMemory` subclass) - for combining `EGLImage`s with a GL
+  texture that replaces `GstEGLImageMemory` bringing the improvements made to the
+  other `GstGLMemory` implementations.  This fixes a performance regression in
+  zerocopy decoding on the Raspberry Pi when used with an updated gst-omx.
+
+##### Miscellaneous improvements
+
+- `gltestsrc` is now usable on devices/platforms with OpenGL 3.x and OpenGL|ES
+  and has completed or gained support for new patterns in line with the
+  existing ones in `videotestsrc`.
+- `gldeinterlace` is now available on devices/platforms with OpenGL|ES
+  implementations.
+- The dispmanx backend (used on the Raspberry Pi) now supports the
+  `gst_video_overlay_set_window_handle()` and
+  `gst_video_overlay_set_render_rectangle()` functions.
+- The `gltransformation` element now correctly transforms mouse coordinates (in
+  window space) to stream coordinates for both perspective and orthographic
+  projections.
+- The `gltransformation` element now detects if the
+  `GstVideoAffineTransformationMeta` is supported downstream and will efficiently
+  pass its transformation downstream. This is a performance improvement as it
+  results in less processing being required.
+- The wayland implementation now uses the multi-threaded safe event-loop API
+  allowing correct usage in applications that call wayland functions from
+  multiple threads.
+- Support for native 90 degree rotations and horizontal/vertical flips
+  in `glimagesink`.
+
+#### Vulkan
+
+- The Vulkan elements now work under Wayland and have received numerous
+  bugfixes.
+
+#### QML elements
+
+- `qmlglsink` video sink now works on more platforms, notably, Windows, Wayland,
+  and Qt's eglfs (for embedded devices with an OpenGL implementation) including
+  the Raspberry Pi.
+- New element `qmlglsrc` to record a QML scene into a GStreamer pipeline.
+
+#### KMS video sink
+
+- New element `kmssink` to render video using Direct Rendering Manager
+  (DRM) and Kernel Mode Setting (KMS) subsystems in the Linux
+  kernel. It is oriented to be used mostly in embedded systems.
+
+#### Wayland video sink
+
+- `waylandsink` now supports the wl_viewporter extension allowing
+  video scaling and cropping to be delegated to the Wayland
+  compositor. This extension is also been made optional, so that it can
+  also work on current compositors that don't support it. It also now has
+  support for the video meta, allowing zero-copy operations in more
+  cases.
+
+#### DVB improvements
+
+- `dvbsrc` now has better delivery-system autodetection and several
+  new parameter sanity-checks to improve its resilience to configuration
+  omissions and errors. Superfluous polling continues to be trimmed down,
+  and the debugging output has been made more consistent and precise.
+  Additionally, the channel-configuration parser now supports the new dvbv5
+  format, enabling `dvbbasebin` to automatically playback content transmitted
+  on delivery systems that previously required manual description, like ISDB-T.
+
+#### DASH, HLS and adaptivedemux
+
+- HLS now has support for Alternate Rendition audio and video tracks. Full
+  support for Alternate Rendition subtitle tracks will be in an upcoming release.
+- DASH received support for keyframe-only trick modes if the
+  `GST_SEEK_FLAG_TRICKMODE_KEY_UNITS` flag is given when seeking. It will
+  only download keyframes then, which should help with high-speed playback.
+  Changes to skip over multiple frames based on bandwidth and other metrics
+  will be added in the near future.
+- Lots of reliability fixes around seek handling and bitrate switching.
+
+#### Bluetooth improvements
+
+- The `avdtpsrc` element now supports metadata such as track title, artist
+  name, and more, which devices can send via AVRCP. These are published as
+  tags on the pipeline.
+- The `a2dpsink` element received some love and was cleaned up so that it
+  actually works after the initial GStreamer 1.0 port.
+
+#### GStreamer VAAPI
+
+- All the decoders have been split, one plugin feature per codec. So
+  far, the available ones, depending on the driver, are:
+  `vaapimpeg2dec`, `vaapih264dec`, `vaapih265dec`, `vaapivc1dec`, `vaapivp8dec`,
+  `vaapivp9dec` and `vaapijpegdec` (which already was split).
+- Improvements when mapping VA surfaces into memory. It now differentiates
+  between negotiation caps and allocations caps, since the allocation
+  memory for surfaces may be bigger than one that is going to be
+  mapped.
+- `vaapih265enc` now supports constant bitrate mode (CBR).
+- Since several VA drivers are unmaintained, we decide to keep a whitelist
+  with the va drivers we actually test, which is mostly the i915 and to a lesser
+  degree gallium from the mesa project. Exporting the environment variable
+  `GST_VAAPI_ALL_DRIVERS` disables the whitelist.
+- Plugin features are registered at run-time, according to their support by
+  the loaded VA driver. So only the decoders and encoder supported by the
+  system are registered. Since the driver can change, some dependencies are
+  tracked to invalidate the GStreamer registry and reload the plugin.
+- `dmabuf` importation from upstream has been improved, gaining performance.
+- `vaapipostproc` now can negotiate buffer transformations via caps.
+- Decoders now can do I-frame only reverse playback. This decodes I-frames
+  only because the surface pool is smaller than the required by the GOP to show all the
+  frames.
+- The upload of frames onto native GL textures has been optimized too, keeping
+  a cache of the internal structures for the offered textures by the sink.
+
+#### V4L2 changes
+
+- More pixels formats are now supported
+- Decoder is now using `G_SELECTION` instead of the deprecated `G_CROP`
+- Decoder now uses the `STOP` command to handle EOS
+- Transform element can now scale the pixel aspect ratio
+- Colorimetry support has been improved even more
+- We now support the `OUTPUT_OVERLAY` type of video node in v4l2sink
+
+#### Miscellaneous
+
+- `multiqueue`'s input pads gained a new `"group-id"` property which
+  can be used to group input streams. Typically one will assign
+  different id numbers to audio, video and subtitle streams for
+  example. This way `multiqueue` can make sure streams of the same
+  type advance in lockstep if some of the streams are unlinked and the
+  `"sync-by-running-time"` property is set. This is used in
+  decodebin3/playbin3 to implement almost-instantaneous stream
+  switching.  The grouping is required because different downstream
+  paths (audio, video, etc.)  may have different buffering/latency
+  etc. so might be consuming data from multiqueue with a slightly
+  different phase, and if we track different stream groups separately
+  we minimize stream switching delays and buffering inside the
+  `multiqueue`.
+- `alsasrc` now supports ALSA drivers without a position for each
+  channel, this is common in some professional or industrial hardware.
+- `libvpx` based decoders (`vp8dec` and `vp9dec`) now create multiple threads on
+  computers with multiple CPUs automatically.
+- `rfbsrc` - used for capturing from a VNC server - has seen a lot of
+  debugging. It now supports the latest version of the RFB
+  protocol and uses GIO everywhere.
+- `tsdemux` can now read ATSC E-AC-3 streams.
+- New `GstVideoDirection` video orientation interface for rotating, flipping
+  and mirroring video in 90° steps. It is implemented by the `videoflip` and
+  `glvideoflip` elements currently.
+- It is now possible to give `appsrc` a duration in time, and there is now a
+  non-blocking try-pull API for `appsink` that returns NULL if nothing is
+  available right now.
+- `x264enc` has support now for chroma-site and colorimetry settings
+- A new JPEG2000 parser element was added, and the JPEG2000 caps were cleaned
+  up and gained more information needed in combination with RTP and various
+  container formats.
+- Reverse playback support for `videorate` and `deinterlace` was implemented
+- Various improvements everywhere for reverse playback and `KEY_UNITS` trick mode
+- New cleaned up `rawaudioparse` and `rawvideoparse` elements that replace the
+  old `audioparse` and `videoparse` elements. There are compatibility element
+  factories registered with the old names to allow existing code to continue
+  to work.
+- The Decklink plugin gained support for 10 bit video SMPTE timecodes, and
+  generally got many bugfixes for various issues.
+- New API in `GstPlayer` for setting the multiview mode for stereoscopic
+  video, setting an HTTP/RTSP user agent and a time offset between audio and
+  video. In addition to that, there were various bugfixes and the new
+  gst-examples module contains Android, iOS, GTK+ and Qt example applications.
+- `GstBin` has new API for suppressing various `GstElement` or `GstObject`
+  flags that would otherwise be affected by added/removed child elements. This
+  new API allows `GstBin` subclasses to handle for themselves if they
+  should be considered a sink or source element, for example.
+- The `subparse` element can handle WebVTT streams now.
+- A new `sdpsrc` element was added that can read an SDP from a file, or get it
+  as a string as property and then sets up an RTP pipeline accordingly.
+
+### Plugin moves
+
+No plugins were moved this cycle. We'll make up for it next cycle, promise!
+
+### Rewritten memory leak tracer
+
+GStreamer has had basic functionality to trace allocation and freeing of
+both mini-objects (buffers, events, caps, etc.) and objects in the form of the
+internal `GstAllocTrace` tracing system. This API was never exposed in the
+1.x API series though. When requested, this would dump a list of objects and
+mini-objects at exit time which had still not been freed at that point,
+enabled with an environment variable. This subsystem has now been removed
+in favour of a new implementation based on the recently-added tracing framework.
+
+Tracing hooks have been added to trace the creation and destruction of
+GstObjects and mini-objects, and a new tracer plugin has been written using
+those new hooks to track which objects are still live and which are not. If
+GStreamer has been compiled against the libunwind library, the new leaks tracer
+will remember where objects were allocated from as well. By default the leaks
+tracer will simply output a warning if leaks have been detected on `gst_deinit()`.
+
+If the `GST_LEAKS_TRACER_SIG` environment variable is set, the leaks tracer
+will also handle the following UNIX signals:
+
+ - `SIGUSR1`: log alive objects
+ - `SIGUSR2`: create a checkpoint and print a list of objects created and
+   destroyed since the previous checkpoint.
+
+Unfortunately this will not work on Windows due to no signals, however.
+
+If the `GST_LEAKS_TRACER_STACK_TRACE` environment variable is set, the leaks
+tracer will also log the creation stack trace of leaked objects. This may
+significantly increase memory consumption however.
+
+New `MAY_BE_LEAKED` flags have been added to GstObject and GstMiniObject, so
+that objects and mini-objects that are likely to stay around forever can be
+flagged and blacklisted from the leak output.
+
+To give the new leak tracer a spin, simply call any GStreamer application such
+as `gst-launch-1.0` or `gst-play-1.0` like this:
+
+    GST_TRACERS=leaks gst-launch-1.0 videotestsrc num-buffers=10 ! fakesink
+
+If there are any leaks, a warning will be raised at the end.
+
+It is also possible to trace only certain types of objects or mini-objects:
+
+    GST_TRACERS="leaks(GstEvent,GstMessage)" gst-launch-1.0 videotestsrc num-buffers=10 ! fakesink
+
+This dedicated leaks tracer is much much faster than valgrind since all code is
+executed natively instead of being instrumented. This makes it very suitable
+for use on slow machines or embedded devices. It is however limited to certain
+types of leaks and won't catch memory leaks when the allocation has been made
+via plain old `malloc()` or `g_malloc()` or other means. It will also not trace
+non-GstObject GObjects.
+
+The goal is to enable leak tracing on GStreamer's Continuous-Integration and
+testing system, both for the regular unit tests (make check) and media tests
+(gst-validate), so that accidental leaks in common code paths can be detected
+and fixed quickly.
+
+For more information about the new tracer, check out Guillaume Desmottes's
+["Tracking Memory Leaks"][leaks-talk] talk or his [blog post][leaks-blog] about
+the topic.

+[leaks-blog]: https://blog.desmottes.be/?post/2016/06/20/GStreamer-leaks-tracer
+
+### GES and NLE changes
+
+- Clip priorities are now handled by the layers, and the GESTimelineElement
+  priority property is now deprecated and unused
+- Enhanced (de)interlacing support to always use the `deinterlace` element
+  and expose needed properties to users
+- Allow reusing clips children after removing the clip from a layer
+- We are now testing many more rendering formats in the gst-validate
+  test suite, and failures have been fixed.
+- Also many bugs have been fixed in this cycle!
+
+### GStreamer validate changes
+
+This cycle has been focused on making GstValidate more than just a validating
+tool, but also a tool to help developers debug their GStreamer issues. When
+reporting issues, we try to gather as much information as possible and expose
+it to end users in a useful way. For an example of such enhancements, check out
+Thibault Saunier's [blog post](improving-debugging-gstreamer-validate) about
+the new Not Negotiated Error reporting mechanism.
+
+Playbin3 support has been added so we can run validate tests with `playbin3`
+instead of playbin.
+
+We are now able to properly communicate between `gst-validate-launcher` and
+launched subprocesses with actual IPC between them. That has enabled the test
+launcher to handle failing tests specifying the exact expected issue(s).
+
+[improving-debugging-gstreamer-validate]: https://blogs.s-osg.org/improving-debugging-gstreamer-validate/
+
+### gst-libav changes
+
+gst-libav uses the recently released ffmpeg 3.2 now, which brings a lot of
+improvements and bugfixes from the ffmpeg team in addition to various new
+codec mappings on the GStreamer side and quite a few bugfixes to the GStreamer
+integration to make it more robust.
+
+## Build and Dependencies
+
+### Experimental support for Meson as build system
+
+#### Overview
+
+We have have added support for building GStreamer using the
+[Meson build system][meson]. This is currently experimental, but should work
+fine at least on Linux using the gcc or clang toolchains and on Windows using
+the MingW or MSVC toolchains.
+
+Autotools remains the primary build system for the time being, but we hope to
+someday replace it and will steadily work towards that goal.
+
+More information about the background and implications of all this and where
+we're hoping to go in future with this can be found in [Tim's mail][meson-mail]
+to the gstreamer-devel mailing list.
+
+For more information on Meson check out [these videos][meson-videos] and also
+the [Meson talk][meson-gstconf] at the GStreamer Conference.
+
+Immediate benefits for Linux users are faster builds and rebuilds. At the time
+of writing the Meson build of GStreamer is used by default in GNOME's jhbuild
+system.
+
+The Meson build currently still lacks many of the fine-grained configuration
+options to enable/disable specific plugins. These will be added back in due
+course.
+
+Note: The meson build files are not distributed in the source tarballs, you will
+need to get GStreamer from git if you want try it out.
+

+[meson-mail]: https://lists.freedesktop.org/archives/gstreamer-devel/2016-September/060231.html
+[meson-videos]: http://mesonbuild.com/videos.html
+[meson-gstconf]: https://gstconf.ubicast.tv/videos/gstreamer-development-on-windows-ans-faster-builds-everywhere-with-meson/
+
+#### Windows Visual Studio toolchain support
+
+Windows users might appreciate being able to build GStreamer using the MSVC
+toolchain, which is not possible using autotools. This means that it will be
+possible to debug GStreamer and applications in Visual Studio, for example.
+We require VS2015 or newer for this at the moment.
+
+There are two ways to build GStreamer using the MSVC toolchain:
+
+1. Using the MSVC command-line tools (`cl.exe` etc.) via Meson's "ninja" backend.
+2. Letting Meson's "vs2015" backend generate Visual Studio project files that
+   can be opened in Visual Studio and compiled from there.
+
+This is currently only for adventurous souls though. All the bits are in place,
+but support for all of this has not been merged into GStreamer's cerbero build
+tool yet at the time of writing. This will hopefully happen in the next cycle,
+but for now this means that those wishing to compile GStreamer with MSVC will
+have to get their hands dirty.
+
+There are also no binary SDK builds using the MSVC toolchain yet.
+
+For more information on GStreamer builds using Meson and the Windows toolchain
+check out Nirbheek Chauhan's blog post ["Building and developing GStreamer using Visual Studio"][msvc-blog].
+
+[msvc-blog]: http://blog.nirbheek.in/2016/07/building-and-developing-gstreamer-using.html
+
+### Dependencies
+
+#### gstreamer
+
+libunwind was added as an optional dependency. It is used only for debugging
+and tracing purposes.
+
+The `opencv` plugin in gst-plugins-bad can now be built against OpenCV
+version 3.1, previously only 2.3-2.5 were supported.
+
+#### gst-plugins-ugly
+
+- `mpeg2dec` now requires at least libmpeg2 0.5.1 (from 2008).
+
+#### gst-plugins-bad
+
+- `gltransformation` now requires at least graphene 1.4.0.
+
+- `lv2` now plugin requires at least lilv 0.16 instead of slv2.
+
+### Packaging notes
+
+Packagers please note that the `gst/gstconfig.h` public header file in the
+GStreamer core library moved back from being an architecture dependent include
+to being architecture independent, and thus it is no longer installed into
+`$(libdir)/gstreamer-1.0/include/gst` but into the normal include directory
+where it lives happily ever after with all the other public header files. The
+reason for this is that we now check whether the target supports unaligned
+memory access based on predefined compiler macros at compile time instead of
+checking it at configure time.
+
+## Platform-specific improvements
+
+### Android
+
+#### New universal binaries for all supported ABIs
+
+We now provide a "universal" tarball to allow building apps against all the
+architectures currently supported (x86, x86-64, armeabi, armeabi-v7a,
+armeabi-v8a). This is needed for building with recent versions of the Android
+NDK which defaults to building against all supported ABIs. Use [the Android
+player example][android-player-example-build] as a reference for the required
+changes.
+
+[android-player-example-build]: https://cgit.freedesktop.org/gstreamer/gst-examples/commit/playback/player/android?id=a5cdde9119f038a1eb365aca20faa9741a38e788
+
+#### Miscellaneous
+
+- New `ahssrc` element that allows reading the hardware sensors, e.g. compass
+  or accelerometer.
+
+### macOS (OS/X) and iOS
+
+- Support for querying available devices on OS/X via the GstDeviceProvider
+  API was added.
+- It is now possible to create OpenGL|ES 3.x contexts on iOS and use them in
+  combination with the VideoToolbox based decoder element.
+- many OpenGL/GLES improvements, see OpenGL section above
+
+### Windows
+
+- gstconfig.h: Always use dllexport/import on Windows with MSVC
+- Miscellaneous fixes to make libs and plugins compile with the MVSC toolchain
+- MSVC toolchain support (see Meson section above for more details)
+
+## New Modules for Documentation, Examples, Meson Build
+
+Three new git modules have been added recently:
+
+### gst-docs
+
+This is a new module where we will maintain documentation in the markdown
+format.
+
+It contains the former gstreamer.com SDK tutorials which have kindly been made
+available by Fluendo under a Creative Commons license. The tutorials have been
+reviewed and updated for GStreamer 1.x and will be available as part of the
+[official GStreamer documentation][doc] going forward. The old gstreamer.com
+site will then be shut down with redirects pointing to the updated tutorials.
+
+Some of the existing docbook XML-formatted documentation from the GStreamer
+core module such as the *Application Development Manual* and the *Plugin
+Writer's Guide* have been converted to markdown as well and will be maintained
+in the gst-docs module in future. They will be removed from the GStreamer core
+module in the next cycle.
+
+This is just the beginning. Our goal is to provide a more cohesive documentation
+experience for our users going forward, and easier to create and maintain
+documentation for developers. There is a lot more work to do, get in touch if
+you want to help out.
+
+If you encounter any problems or spot any omissions or outdated content in the
+new documentation, please [file a bug in bugzilla][doc-bug] to let us know.
+
+We will probably release gst-docs as a separate tarball for distributions to
+package in the next cycle.
+
+[doc]: http://gstreamer.freedesktop.org/documentation/
+[doc-bug]: https://bugzilla.gnome.org/enter_bug.cgi?product=GStreamer&component=documentation
+
+### gst-examples
+
+A new [module][examples-git] has been added for examples. It does not contain
+much yet, currently it only contains a small [http-launch][http-launch] utility
+that serves a pipeline over http as well as various [GstPlayer playback frontends][puis]
+for Android, iOS, Gtk+ and Qt.
+
+More examples will be added over time. The examples in this repository should
+be more useful and more substantial than most of the examples we ship as part
+of our other modules, and also written in a way that makes them good example
+code. If you have ideas for examples, let us know.
+
+No decision has been made yet if this module will be released and/or packaged.
+It probably makes sense to do so though.
+
+[examples-git]: https://cgit.freedesktop.org/gstreamer/gst-examples/tree/
+[http-launch]: https://cgit.freedesktop.org/gstreamer/gst-examples/tree/network/http-launch/
+[puis]: https://cgit.freedesktop.org/gstreamer/gst-examples/tree/playback/player
+
+### gst-build
+
+[gst-build][gst-build-git] is a new meta module to build GStreamer using the
+new Meson build system. This module is not required to build GStreamer with
+Meson, it is merely for convenience and aims to provide a development setup
+similar to the existing `gst-uninstalled` setup.
+
+gst-build makes use of Meson's [subproject feature][meson-subprojects] and sets
+up the various GStreamer modules as subprojects, so they can all be updated and
+built in parallel.
+
+This module is still very new and highly experimental. It should work at least
+on Linux and Windows (OS/X needs some build fixes). Let us know of any issues
+you encounter by popping into the `#gstreamer` IRC channel or by
+[filing a bug][gst-build-bug].
+
+This module will probably not be released or packaged (does not really make sense).

+## Bugs fixed in 1.10
+
+More than [750 bugs][bugs-fixed-in-1.10] have been fixed during
+the development of 1.10.
+
+This list does not include issues that have been cherry-picked into the
+stable 1.8 branch and fixed there as well, all fixes that ended up in the
+1.8 branch are also included in 1.10.
+
+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.
+
+[bugs-fixed-in-1.10]: https://bugzilla.gnome.org/buglist.cgi?bug_status=RESOLVED&bug_status=VERIFIED&classification=Platform&limit=0&list_id=164074&order=bug_id&product=GStreamer&query_format=advanced&resolution=FIXED&target_milestone=1.8.1&target_milestone=1.8.2&target_milestone=1.8.3&target_milestone=1.8.4&target_milestone=1.9.1&target_milestone=1.9.2&target_milestone=1.9.90&target_milestone=1.10.0
+
+## Stable 1.10 branch
+
+After the 1.10.0 release there will be several 1.10.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 1.10.x bug-fix releases will be made from the git 1.10 branch,
+which is a stable branch.
+
+### 1.10.0
+
+1.10.0 was released on 1st November 2016.
+
+## Known Issues
+
+- iOS builds with iOS 6 SDK and old C++ STL. You need to select iOS 6 instead
+  of 7 or 8 in your projects settings to be able to link applications.
+  [Bug #766366](https://bugzilla.gnome.org/show_bug.cgi?id=766366)
+- Code signing for Apple platforms has some problems currently, requiring
+  manual work to get your application signed. [Bug #771860](https://bugzilla.gnome.org/show_bug.cgi?id=771860)
+- Building applications with Android NDK r13 on Windows does not work. Other
+  platforms and earlier/later versions of the NDK are not affected.
+  [Bug #772842](https://bugzilla.gnome.org/show_bug.cgi?id=772842)
+- The new leaks tracer may deadlock the application (or exhibit other undefined
+  behaviour) when `SIGUSR` handling is enabled via the `GST_LEAKS_TRACER_SIG`
+  environment variable. [Bug #770373](https://bugzilla.gnome.org/show_bug.cgi?id=770373)
+- vp8enc crashes on 32 bit Windows, but was working fine in 1.6. 64 bit Windows is unaffected.
+  [Bug #763663](https://bugzilla.gnome.org/show_bug.cgi?id=763663)
+
+## Schedule for 1.12
+
+Our next major feature release will be 1.12, and 1.11 will be the unstable
+development version leading up to the stable 1.12 release. The development
+of 1.11/1.12 will happen in the git master branch.
+
+The plan for the 1.12 development cycle is yet to be confirmed, but it is
+expected that feature freeze will be around early/mid-January,
+followed by several 1.11 pre-releases and the new 1.12 stable release
+in March.
+
+1.12 will be backwards-compatible to the stable 1.10, 1.8, 1.6, 1.4, 1.2 and
+1.0 release series.
