+
+	* plugins/nle/nlecomposition.c:
+	  nlecomposition: ensure elements pending to be added are not leaked
+	  When nlecomposition is finalized with pending add action or io,
+	  associated elements are not unreffed as they should since caller gives
+	  us the reference when calling gst_bin_add causing them to be leaked.
+	  So to make sure we don't leak a reference on element when adding one to
+	  the bin, each stage (action and pending_io) hold a reference on element
+	  and release it when stage is done.

+	  We don't add internal bin, we remove it.

+	  This is the only header which shall be included by user. Otherwise some

-stable 1.x API series of your favourite cross-platform multimedia framework!
-
-As always, this release is again packed with new features, bug fixes and other
-improvements.
-
-See [https://gstreamer.freedesktop.org/releases/1.8/][latest] for the latest
-version of this document.

-
-## Highlights
-
-- **Hardware-accelerated zero-copy video decoding on Android**
-
-- **New video capture source for Android using the android.hardware.Camera API**
-
-- **Windows Media reverse playback** support (ASF/WMV/WMA)
-
-- **New tracing system** provides support for more sophisticated debugging tools
-
-- **New high-level GstPlayer playback convenience API**
-
-- **Initial support for the new [Vulkan][vulkan] API**, see
-  [Matthew Waters' blog post][vulkan-in-gstreamer] for more details
-
-- **Improved Opus audio codec support**: Support for more than two channels; MPEG-TS demuxer/muxer can now handle Opus;
-  [sample-accurate][opus-sample-accurate] encoding/decoding/transmuxing with
-  Ogg, Matroska, ISOBMFF (Quicktime/MP4), and MPEG-TS as container;
-  [new codec utility functions for Opus header and caps handling][opus-codec-utils]
-  in pbutils library. The Opus encoder/decoder elements were also moved to
-  gst-plugins-base (from -bad), and the opus RTP depayloader/payloader to -good.

-
-## Major new features and changes
-
-### Noteworthy new API, features and other changes
-
-- New GstVideoAffineTransformationMeta meta for adding a simple 4x4 affine
-  transformation matrix to video buffers
-
-- [g\_autoptr()](https://developer.gnome.org/glib/stable/glib-Miscellaneous-Macros.html#g-autoptr)
-  support for all types is exposed in GStreamer headers now, in combination
-  with a sufficiently-new GLib version (i.e. 2.44 or later). This is primarily
-  for the benefit of application developers who would like to make use of
-  this, the GStreamer codebase itself will not be using g_autoptr() for
-  the time being due to portability issues.
-
-- GstContexts are now automatically propagated to elements added to a bin
-  or pipeline, and elements now maintain a list of contexts set on them.
-  The list of contexts set on an element can now be queried using the new functions
-  [gst\_element\_get\_context()](https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/GstElement.html#gst-element-get-context)
-  and [gst\_element\_get\_contexts()](https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/GstElement.html#gst-element-get-contexts). GstContexts are used to share context-specific configuration objects
-  between elements and can also be used by applications to set context-specific
-  configuration objects on elements, e.g. for OpenGL or Hardware-accelerated
-  video decoding.
-
-- New [GST\_BUFFER\_DTS\_OR\_PTS()](https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/GstBuffer.html#GST-BUFFER-DTS-OR-PTS:CAPS)
-  convenience macro that returns the decode timestamp if one is set and
-  otherwise returns the presentation timestamp
-
-- New GstPadEventFullFunc that returns a GstFlowReturn instead of a gboolean.
-  This new API is mostly for internal use and was added to fix a race condition
-  where occasionally internal flow error messages were posted on the bus when
-  sticky events were propagated at just the wrong moment whilst the pipeline
-  was shutting down. This happened primarily when the pipeline was shut down
-  immediately after starting it up. GStreamer would not know that the reason
-  the events could not be propagated was because the pipeline was shutting down
-  and not some other problem, and now the flow error allows GStreamer to know
-  the reason for the failure (and that there's no reason to post an error
-  message). This is particularly useful for queue-like elements which may need
-  to asynchronously propagate a previous flow return from downstream.
-
-- Pipeline dumps in form of "dot files" now also show pad properties that
-  differ from their default value, the same as it does for elements. This is
-  useful for elements with pad subclasses that provide additional properties,
-  e.g. videomixer or compositor.
-
-- Pad probes are now guaranteed to be called in the order they were added
-  (before they were called in reverse order, but no particular order was
-  documented or guaranteed)
-
-- Plugins can now have dependencies on device nodes (not just regular files)
-  and also have a prefix filter. This is useful for plugins that expose
-  features (elements) based on available devices, such as the video4linux
-  plugin does with video decoders on certain embedded systems.
-
-- gst\_segment\_to\_position() has been deprecated and been replaced by the
-  better-named gst\_segment\_position\_from\_running\_time(). At the same time
-  gst\_segment\_position\_from\_stream\_time() was added, as well as \_full()
-  variants of both to deal with negative stream time.
-
-- GstController: the interpolation control source gained a new monotonic cubic
-  interpolation mode that, unlike the existing cubic mode, will never overshoot
-  the min/max y values set.
-
-- GstNetAddressMeta: can now be read from buffers in language bindings as well,
-  via the new gst\_buffer\_get\_net\_address\_meta() function
-
-- ID3 tag PRIV frames are now extraced into a new GST\_TAG\_PRIVATE\_DATA tag
-
-- gst-launch-1.0 and gst\_parse\_launch() now warn in the most common case if
-  a dynamic pad link could not be resolved, instead of just silently
-  waiting to see if a suitable pad appears later, which is often perceived
-  by users as hanging -- they are now notified when this happens and can check
-  their pipeline.
-
-- GstRTSPConnection now also parses custom RTSP message headers and retains
-  them for the application instead of just ignoring them
-
-- rtspsrc handling of  authentication over tunneled connections (e.g. RTSP over HTTP)
-  was fixed
-
-- gst\_video\_convert\_sample() now crops if there is a crop meta on the input buffer
-
-- The debugging system printf functions are now exposed for general use, which
-  supports special printf format specifiers such as GST\_PTR\_FORMAT and
-  GST\_SEGMENT\_FORMAT to print GStreamer-related objects. This is handy for
-  systems that want to prepare some debug log information to be output at a
-  later point in time. The GStreamer-OpenGL subsystem is making use of these
-  new functions, which are [gst\_info\_vasprintf()][gst_info_vasprintf],
-    [gst\_info\_strdup\_vprintf()][gst_info_strdup_vprintf] and
-    [gst\_info\_strdup\_printf()][gst_info_strdup_printf].
-
-- videoparse: "strides", "offsets" and "framesize" properties have been added to
-  allow parsing raw data with strides and padding that do not match GStreamer
-  defaults.
-
-- GstPreset reads presets from the directories given in GST\_PRESET\_PATH now.
-  Presets are read from there after presets in the system path, but before
-  application and user paths.

-### New Elements
-
-- [netsim](): a new (resurrected) element to simulate network jitter and
-  packet dropping / duplication.
-
-- New VP9 RTP payloader/depayloader elements: rtpvp9pay/rtpvp9depay
-
-- New [videoframe_audiolevel]() element, a video frame synchronized audio level element
-
-- New spandsp-based tone generator source
-
-- New NVIDIA NVENC-based H.264 encoder for GPU-accelerated video encoding on
-  suitable NVIDIA hardware
-
-- [rtspclientsink](), a new RTSP RECORD sink element, was added to gst-rtsp-server
-
-- [alsamidisrc](), a new ALSA MIDI sequencer source element
-
-### Noteworthy element features and additions
-
-- *identity*: new ["drop-buffer-flags"](https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer-plugins/html/gstreamer-plugins-identity.html#GstIdentity--drop-buffer-flags)
-  property to drop buffers based on buffer flags. This can be used to drop all
-  non-keyframe buffers, for example.
-
-- *multiqueue*: various fixes and improvements, in particular special handling
-  for sparse streams such as substitle streams, to make sure we don't overread
-  them any more. For sparse streams it can be normal that there's no buffer for
-  a long period of time, so having no buffer queued is perfectly normal. Before
-  we would often unnecessarily try to fill the subtitle stream queue, which
-  could lead to much more data being queued in multiqueue than necessary.
-
-- *multiqueue*/*queue*: When dealing with time limits, these elements now use the
-  new ["GST_BUFFER_DTS_OR_PTS"](https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/GstBuffer.html#GST-BUFFER-DTS-OR-PTS:CAPS)
-  and ["gst_segment_to_running_time_full()"](https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/GstSegment.html#gst-segment-to-running-time-full)
-  API, resulting in more accurate levels, especially when dealing with non-raw
-  streams (where reordering happens, and we want to use the increasing DTS as
-  opposed to the non-continuously increasing PTS) and out-of-segment input/output.
-  Previously all encoded buffers before the segment start, which can happen when
-  doing ACCURATE seeks, were not taken into account in the queue level calculation.
-
-- *multiqueue*: New ["use-interleave"](https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer-plugins/html/gstreamer-plugins-multiqueue.html#GstMultiQueue--use-interleave)
-  property which allows the size of the queues to be optimized based on the input
-  streams interleave. This should only be used with input streams which are properly
-  timestamped. It will be used in the future decodebin3 element.
-
-- *queue2*: new ["avg-in-rate"](https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer-plugins/html/gstreamer-plugins-queue2.html#GstQueue2--avg-in-rate)
-  property that returns the average input rate in bytes per second
-
-- audiotestsrc now supports all audio formats and is no longer artificially
-  limited with regard to the number of channels or sample rate
-
-- gst-libav (ffmpeg codec wrapper): map and enable JPEG2000 decoder
-
-- multisocketsink can, on request, send a custom GstNetworkMessage event
-  upstream whenever data is received from a client on a socket. Similarly,
-  socketsrc will, on request, pick up GstNetworkMessage events from downstream
-  and send any data contained within them via the socket. This allows for
-  simple bidirectional communication.
-
-- matroska muxer and demuxer now support the ProRes video format
-
-- Improved VP8/VP9 decoding performance on multi-core systems by enabling
-  multi-threaded decoding in the libvpx-based decoders on such systems
-
-- appsink has a new ["wait-on-eos"](https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-plugins/html/gst-plugins-base-plugins-appsink.html#GstAppSink--wait-on-eos)
-  property, so in cases where it is uncertain if an appsink will have a consumer for
-  its buffers when it receives an EOS this can be set to FALSE to ensure that the
-  appsink will not hang.
-
-- rtph264pay and rtph265pay have a new "config-interval" mode -1 that will
-  re-send the setup data (SPS/PPS/VPS) before every keyframe to ensure
-  optimal coverage and the shortest possibly start-up time for a new client
-
-- mpegtsmux can now mux H.265/HEVC video as well
-
-- The MXF muxer was ported to 1.x and produces more standard conformant files now
-  that can be handled by more other software; The MXF demuxer got improved
-  support for seek tables (IndexTableSegments).
-
-### Plugin moves
-
-- The rtph265pay/depay RTP payloader/depayloader elements for H.265/HEVC video
-  from the rtph265 plugin in -bad have been moved into the existing rtp plugin
-  in gst-plugins-good.
-
-- The mpg123 plugin containing a libmpg123 based audio decoder element has
-  been moved from -bad to -ugly.
-
-- The Opus encoder/decoder elements have been moved to gst-plugins-base and
-  the RTP payloader to gst-plugins-good, both coming from gst-plugins-bad.
-
-### New tracing tools for developers
-
-A new tracing subsystem API has been added to GStreamer, which provides
-external tracers with the possibility to strategically hook into GStreamer
-internals and collect data that can be evaluated later. These tracers are a
-new type of plugin features, and GStreamer core ships with a few example
-tracers (latency, stats, rusage, log) to start with. Tracers can be loaded
-and configured at start-up via an environment variable (GST\_TRACER\_PLUGINS).
-
-Background: While GStreamer provides plenty of data on what's going on in a
-pipeline via its debug log, that data is not necessarily structured enough to
-be generally useful, and the overhead to enable logging output for all data
-required might be too high in many cases. The new tracing system allows tracers
-to just obtain the data needed at the right spot with as little overhead as
-possible, which will be particularly useful on embedded systems.
-
-Of course it has always been possible to do performance benchmarks and debug
-memory leaks, memory consumption and invalid memory access using standard
-operating system tools, but there are some things that are difficult to track
-with the standard tools, and the new tracing system helps with that. Examples
-are things such as latency handling, buffer flow, ownership transfer of
-events and buffers from element to element, caps negotiation, etc.
-
-For some background on the new tracing system, watch Stefan Sauer's
-GStreamer Conference talk ["A new tracing subsystem for GStreamer"][tracer-0]
-and for a more specific example how it can be useful have a look at
-Thiago Santos's lightning talk ["Analyzing caps negotiation using GstTracer"][tracer-1]
-and his ["GstTracer experiments"][tracer-2] blog post. There was also a Google
-Summer of Code project in 2015 that used tracing system for a graphical
-GStreamer debugging tool ["gst-debugger"][tracer-3].
-
-This is all still very much work in progress, but we hope this will provide the
-foundation for a whole suite of new debugging tools for GStreamer pipelines.

-
-### GstPlayer: a new high-level API for cross-platform multimedia playback
-
-GStreamer has had reasonably high-level API for multimedia playback
-in the form of the playbin element for a long time. This allowed application
-developers to just configure a URI to play, and playbin would take care of
-everything else. This works well, but there is still way too much to do on
-the application-side to implement a fully-featured playback application, and
-too much general GStreamer pipeline API exposed, making it less accessible
-to application developers.
-
-Enter GstPlayer. GstPlayer's aim is to provide an even higher-level abstraction
-of a fully-featured playback API but specialised for its specific use case. It
-also provides easy integration with and examples for Gtk+, Qt, Android, OS/X,
-iOS and Windows. Watch Sebastian's [GstPlayer talk at the GStreamer Conference][gstplayer-talk]
-for more information, or check out the [GstPlayer API reference][gstplayer-api]
-and [GstPlayer examples][gstplayer-examples].

-[gstplayer-examples]: https://github.com/sdroege/gst-player/
-
-### Adaptive streaming: DASH, HLS and MSS improvements
-
-- dashdemux now supports loading external xml nodes pointed from its MPD.
-
-- Content protection nodes parsing support for PlayReady WRM in mssdemux.
-
-- Reverse playback was improved to respect seek start and stop positions.
-
-- Adaptive demuxers (hlsdemux, dashdemux, mssdemux) now support the SNAP_AFTER
-  and SNAP_BEFORE seek flags which will jump to the nearest fragment boundary
-  when executing a seek, which means playback resumes more quickly after a seek.
-
-### Audio library improvements
-
-- audio conversion, quantization and channel up/downmixing functionality
-  has been moved from the audioconvert element into the audio library and
-  is now available as public API in form of [GstAudioConverter][audio-0],
-  [GstAudioQuantize][audio-1] and [GstAudioChannelMixer][audio-2].
-  Audio resampling will follow in future releases.
-
-- [gst\_audio\_channel\_get\_fallback\_mask()][audio-3] can be used
-  to retrieve a default channel mask for a given number of channels as last
-  resort if the layout is unknown
-
-- A new [GstAudioClippingMeta][audio-4] meta was added for specifying clipping
-  on encoded audio buffers
-
-- A new GstAudioVisualizer base class for audio visualisation elements;
-  most of the existing visualisers have been ported over to the new base class.
-  This new base class lives in the pbutils library rather than the audio library,
-  since we'd have had to make libgstaudio depend on libgstvideo otherwise,
-  which was deemed undesirable.

-
-### GStreamer OpenGL support improvements
-
-#### Better OpenGL Shader support
-
-[GstGLShader][shader] has been revamped to allow more OpenGL shader types
-by utilizing a new GstGLSLStage object.  Each stage holds an OpenGL pipeline
-stage such as a vertex, fragment or a geometry shader that are all compiled
-separately into a program that is executed.
-
-The glshader element has also received a revamp as a result of the changes in
-the library.  It does not take file locations for the vertex and fragment
-shaders anymore.  Instead it takes the strings directly leaving the file
-management to the application.
-
-A new [example][liveshader-example] was added utilizing the new shader
-infrastructure showcasing live shader edits.
-
-[shader]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-bad-libs/html/gst-plugins-bad-libs-gstglshader.html
-[liveshader-example]: https://cgit.freedesktop.org/gstreamer/gst-plugins-bad/tree/tests/examples/gtk/glliveshader.c
-
-#### OpenGL GLMemory rework
-
-[GstGLMemory] was extensively reworked to support the addition of multiple
-texture targets required for zero-copy integration with the Android
-MediaCodec elements.  This work was also used to provide IOSurface based
-GLMemory on OS X for zero-copy with OS X's VideoToolbox decoder (vtdec) and
-AV Foundation video source (avfvideosrc).  There are also patches in bugzilla
-for GstGLMemoryEGL specifically aimed at improving the decoding performance on
-the Raspberry Pi.
-
-[GstGLMemory]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-bad-libs/html/gst-plugins-bad-libs-gstglmemory.html
-
-A texture-target field was added to video/x-raw(memory:GLMemory) caps to signal
-the texture target contained in the GLMemory.  Its values can be 2D, rectangle
-or external-oes.  glcolorconvert can convert between the different formats as
-required and different elements will accept or produce different targets.  e.g.
-glimagesink can take and render external-oes textures directly as required for
-effecient zero-copy on android.
-
-A generic GL allocation framework was also implemented to support the generic
-allocation of OpenGL buffers and textures which is used extensively by
-GstGLBufferPool.
-
-#### OpenGL DMABuf import uploader
-
-There is now a DMABuf uploader available for automatic selection that will
-attempt to import the upstream provided DMABuf.  The uploader will import into
-2D textures with the necesarry format.  YUV to RGB conversion is still provided
-by glcolorconvert to avoid the laxer restrictions with external-oes textures.
-
-#### OpenGL queries
-
-Queries of various aspects of the OpenGL runtime such as timers, number of
-samples or the current timestamp are not possible.  The GstGLQuery object uses a
-delayed debug system to delay the debug output to later to avoid expensive calls
-to the glGet\* family of functions directly after finishing a query.  It is
-currently used to output the time taken to perform various operations of texture
-uploads and downloads in GstGLMemory.
-
-#### New OpenGL elements
-
-glcolorbalance has been created mirroring the videobalance elements.
-glcolorbalance provides the exact same interface as videobalance so can be used
-as a GPU accelerated replacement.  glcolorbalance has been added to glsinkbin so
-usage with playsink/playbin will use it automatically instead of videobalance
-where possible.
-
-glvideoflip, which is the OpenGL equiavalant of videoflip, implements the exact
-same interface and functionality as videoflip.
-
-#### EGL implementation now selects OpenGL 3.x
-
-The EGL implementation can now select OpenGL 3.x contexts.
-
-#### OpenGL API removal
-
-The GstGLDownload library object was removed as it was not used by anything.
-Everything is performed by GstGLMemory or in the gldownloadelement.
-
-The GstGLUploadMeta library object was removed as it was not being used and we
-don't want to promote the use of GstVideoGLTextureUploadMeta.
-
-#### OpenGL: Other miscellaneous changes
-
-- The EGL implementation can now select OpenGL 3.x contexts.  This brings
-  OpenGL 3.x to e.g. wayland and other EGL systems.
-
-- glstereomix/glstereosplit are now built and are usable on OpenGL ES systems
-
-- The UYVY/YUY2 to RGBA and RGBA to UYVY/YUY2 shaders were fixed removing the
-  sawtooth pattern and luma bleeding.
-
-- We now utilize the GL\_APPLE\_sync extension on iOS devices which improves
-  performance of OpenGL applications, especially with multiple OpenGL
-  contexts.
-
-- glcolorconvert now uses a bufferpool to avoid costly
-  glGenTextures/glDeleteTextures for every frame.
-
-- glvideomixer now has full glBlendFunc and glBlendEquation support per input.
-
-- gltransformation now support navigation events so your weird transformations
-  also work with DVD menus.
-
-- qmlglsink can now run on iOS, OS X and Android in addition to the already
-  supported Linux platform.
-
-- glimagesink now posts unhandled keyboard and mouse events (on backends that
-  support user input, current only X11) on the bus for the application.
-
-### Initial GStreamer Vulkan support
-
-Some new elements, vulkansink and vulkanupload have been implemented utilizing
-the new Vulkan API.  The implementation is currently limited to X11 platforms
-(via xcb) and does not perform any scaling of the stream's contents to the size
-of the available output.
-
-A lot of infrasctructure work has been undertaken to support using Vulkan in
-GStreamer in the future.  A number of GstMemory subclasses have been created for
-integrating Vulkan's GPU memory handling along with VkBuffer's and VkImage's
-that can be passed between elements.  Some GStreamer refcounted wrappers for
-global objects such as VkInstance, VkDevice, VkQueue, etc have also been
-implemented along with GstContext integration for sharing these objects with the
-application.
-
-### GStreamer VAAPI support for hardware-accelerated video decoding and encoding on Intel (and other) platforms
-
-#### GStreamer VAAPI is now part of upstream GStreamer
-
-The GStreamer-VAAPI module which provides support for hardware-accelerated
-video decoding, encoding and post-processing on Intel graphics hardware
-on Linux has moved from its previous home at the [Intel Open Source Technology Center][iostc]
-to the upstream GStreamer repositories, where it will in future be maintained
-as part of the upstream GStreamer project and released in lockstep with the
-other GStreamer modules. The current maintainers will continue to spearhead
-the development at the new location:
-
-[http://cgit.freedesktop.org/gstreamer/gstreamer-vaapi/][gst-vaapi-git]
-
-[gst-vaapi-git]: http://cgit.freedesktop.org/gstreamer/gstreamer-vaapi/
-
-GStreamer-VAAPI relies heavily on certain GStreamer infrastructure API that
-is still in flux such as the OpenGL integration API or the codec parser
-libraries, and one of the goals of the move was to be able to leverage
-new developments early and provide tighter integration with the latest
-developments of those APIs and other graphics-related APIs provided by
-GStreamer, which should hopefully improve performance even further and in
-some cases might also provide better stability.
-
-Thanks to everyone involved in making this move happen!
-
-#### GStreamer VAAPI: Bug tracking
-
-Bugs had already been tracked on [GNOME bugzilla](bgo) but will be moved
-from the gstreamer-vaapi product into a new gstreamer-vaapi component of
-the GStreamer product in bugzilla. Please file new bugs against the new
-component in the GStreamer product from now on.
-
-#### GStreamer VAAPI: Pending patches
-
-The code base has been re-indented to the GStreamer code style, which
-affected some files more than others. This means that some of the patches
-in bugzilla might not apply any longer, so if you have any unmerged patches
-sitting in bugzilla please consider checking if they still apply cleany and
-refresh them if not. Sorry for any inconvenience this may cause.
-
-#### GStreamer VAAPI: New versioning scheme and supported GStreamer versions
-
-The version numbering has been changed to match the GStreamer version
-numbering to avoid confusion: there is a new gstreamer-vaapi 1.6.0 release
-and a 1.6 branch that is roughly equivalent to the previous 0.7.0 version.
-Future releases 1.7.x and 1.8.x will be made alongside GStreamer releases.
-
-While it was possible and supported by previous releases to build against
-a whole range of different GStreamer versions (such as 1.2, 1.4, 1.6 or 1.7/1.8),
-in the future there will only be one target branch, so that git master will
-track GStreamer git master, 1.8.x will target GStreamer 1.8, and
-1.6.x will target the 1.6 series.
-
-[iostc]: http://01.org
-[bgo]:   http://bugzilla.gnome.og
-
-#### GStreamer VAAPI: Miscellaneous changes
-
-All GStreamer-VAAPI functionality is now provided solely by its GStreamer
-elements. There is no more public library exposing GstVaapi API, this API
-was only ever meant for private use by the elements. Parts of it may be
-resurrected again in future if needed, but for now it has all been made
-private.
-
-GStreamer-VAAPI now unconditionally uses the codecparser library in
-gst-plugins-bad instead of shipping its own internal copy. Similarly,
-it no longer ships its own codec parsers but relies on the upstream
-codec parser elements.
-
-The GStreamer-VAAPI encoder elements have been renamed from vaapiencode_foo
-to vaapifooenc, so encoders are now called vaapih264enc, vaapih265enc,
-vaapimpeg2enc, vaapijpegenc, and vaapivp8enc. With this change we now follow
-the standard names in GStreamer, and the plugin documentation is generated
-correctly.
-
-In the case of the decoders, only the jpeg decoder has been split from the
-general decoding element vaapidecode: vaapijpegdec. This is the first step to
-split per codec each decoding element. The vaapijpegdec has also been given
-marginal rank for the time being.
-
-#### GStreamer VAAPI: New features in 1.8: 10-bit H.265/HEVC decoding support
-
-Support for decoding 10-bit H.265/HEVC has been added. For the time being
-this only works in combination with vaapisink though, until support for the
-P010 video format used internally is added to GStreamer and to the
-vaGetImage()/vaPutimage() API in the vaapi-intel-driver.
-
-Several fixes for memory leaks, build errors, and in the internal
-video parsing.
-
-Finally, vaapisink now posts the unhandled keyboard and mouse events to the
-application.
-
-### GStreamer Video 4 Linux Support
-
-Colorimetry support has been enhanced even more. It will now properly select
-default values when not specified by the driver. The range of color formats
-supported by GStreamer has been greatly improved. Notably, support for
-multi-planar I420 has been added along with all the new and non-ambiguous RGB
-formats that got added in recent kernels.
-
-The device provider now exposes a variety of properties as found in the udev
-database.
-
-The video decoder is now able to negotiate the downstream format.
-
-Elements that are dynamically created from /dev/video\* now track changes on
-these devices to ensure the registry stay up to date.
-
-All this and various bug fixes that improve both stability and correctness.
-
-### GStreamer Editing Services
-
-Added APIs to handle asset proxying support. Proxy creation is not the
-responsibility of GES itself, but GES provides all the needed features
-for it to be cleanly handled at a higher level.
-
-Added support for changing playback rate.  This means that now, whenever a
-user adds a 'pitch' element (as it is the only known element to change playback
-rate through properties), GES will handle everything internally. This change
-introduced a new media-duration-factor property in NleObject which will
-lead to tweaking of seek events so they have the proper playback range to be
-requested upstream.
-
-Construction of NLE objects has been reworked making copy/pasting fully
-functional and allowing users to set properties on effects right after
-creating them.
-
-Rework of the title source to add more flexibility in text positioning,
-and letting the user get feedback about rendered text positioning.
-
-Report nlecomposition structural issues (coming from user programing mistakes)
-into ERROR messages on the bus.
-
-Add GI/pythyon testsuite in GES itself, making sure the API is working as expected
-in python, and allowing writing tests faster.
-
-### GstValidate
-
-Added support to run tests inside gdb.
-
-Added a 'smart' reporting mode where we give as much information as possible about
-critical errors.
-
-Uses GstTracer now instead of a LD\_PRELOAD library.
-
-## Miscellaneous
-
-- encodebin now works with "encoder-muxers" such as wavenc
-
-- gst-play-1.0 acquired a new keyboard shortcut: '0' seeks back to the start
-
-- gst-play-1.0 supports two new command line switches: -v for verbose output
-  and --flags to configure the playbin flags to use.
-
-## Build and Dependencies
-
-- The GLib dependency requirement was bumped to 2.40
-
-- The -Bsymbolic configure check now works with clang as well
-
-- ffmpeg is now required as libav provider, incompatible changes were
-  introduced that make it no longer viable to support both FFmpeg and Libav
-  as libav providers. Most major distros have switched to FFmpeg or are in
-  the process of switching to it anyway, so we don't expect this to be a
-  problem, and there is still an internal copy of ffmpeg that can be used
-  as fallback if needed.
-
-- The internal ffmpeg snapshot is now FFMpeg 3.0, but it should be possible
-  to build against 2.8 as well for the time being.
-
-## Platform-specific improvements
-
-### Android
-
-- Zero-copy video decoding on Android using the hardware-accelerated decoders
-  has been implemented, and is fully integrated with the GStreamer OpenGL stack
-
-- ahcsrc, a new camera source element, has been merged and can be used to
-  capture video on android devices. It uses the android.hardware.Camera Java
-  API to capture from the system's cameras.
-
-- The OpenGL-based QML video sink can now also be used on Android
-
-- New tinyalsasink element, which is mainly useful for Android but can also
-  be used on other platforms.
-
-### OS/X and iOS
-
-- The system clock now uses mach\_absolute\_time() on OSX/iOS, which is
-  the preferred high-resolution monotonic clock to be used on Apple platforms
-
-- The OpenGL-based QML video sink can now also be used on OS X and iOS (with
-  some Qt build system massaging)
-
-- New IOSurface based memory implementation in avfvideosrc and vtdec on OS X
-  for zerocopy with OpenGL.  The previously used OpenGL extension
-  GL_APPLE_ycbcr_422 is not compatible with GL 3.x core contexts.
-
-- New GstAppleCoreVideoMemory wrapping CVPixelBuffer's
-
-- avfvideosrc now supports renegotiation.
-
-### Windows
-
-- Various bugs with UDP and multicast were fixed on Windows, mostly related to
-  gst-rtsp-server.
-
-- A few bugs in directsoundsrc and directsoundsink were fixed that could cause
-  the element to lock up. Also the "mute" property on the sink was fixed, and
-  a new "device" property for device selection was added to the source.
-
-## Known Issues
-
-- Building GStreamer applications with the Android NDK r11 is currently not
-  supported due to incompatible changes in the NDK. This is expected to be
-  fixed for 1.8.1.
-  [Bugzilla #763999](https://bugzilla.gnome.org/show_bug.cgi?id=763999)
-
-- vp8enc crashes on 32 bit Windows, but was working fine in 1.6. 64 bit
-  Windows is unaffected.
-  [Bugzilla #763663](https://bugzilla.gnome.org/show_bug.cgi?id=763663)

-## Bugs fixed in 1.8
-
-More than [~700 bugs][bugs-fixed-in-1.8] have been fixed during
-the development of 1.8.
-
-This list does not include issues that have been cherry-picked into the
-stable 1.6 branch and fixed there as well, all fixes that ended up in the
-1.6 branch are also included in 1.8.
-
-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 1.8 branch
-
-After the 1.8.0 release there will be several 1.8.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 1.8.x bug-fix releases will be made from the git 1.8 branch, which
-is a stable branch.
-
-### 1.8.0
-
-1.8.0 was released on 24 March 2016.
-
-### 1.8.1
-
-The first 1.8 bug-fix release (1.8.1) is planned for April 2016.
-
-## Schedule for 1.10
-
-Our next major feature release will be 1.10, and 1.9 will be the unstable
-development version leading up to the stable 1.10 release. The development
-of 1.9/1.10 will happen in the git master branch.
-
-The plan for the 1.10 development cycle is yet to be confirmed, but it is
-expected that feature freeze will be around late July or early August,
-followed by several 1.9 pre-releases and the new 1.10 stable release
-in September.
-
-1.10 will be backwards-compatible to the stable 1.8, 1.6, 1.4, 1.2 and 1.0
-release series.
