+# GStreamer 1.8 Release Notes
+**GStreamer 1.8.0 was released on 24 March 2016.**
+The GStreamer team is proud to announce a new major feature release in the
+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
+See [][latest] for the latest
+version of this document.
+*Last updated: Thursday 24 March 2016, 10:00 UTC [(log)][gitlog]*
+## 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.
+ [opus-sample-accurate]:
+ [opus-codec-utils]:
+- **GStreamer VAAPI module now released and maintained as part of the GStreamer project**
+ [vulkan]:
+ [vulkan-in-gstreamer]:
+## 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()](
+ 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()](
+ and [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()](
+ 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"](
+ 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
+ and ["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"](
+ 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"](
+ 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"](
+ 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].
+### 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.
+#### 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.
+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
+#### 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
+### 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:
+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.
+[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
+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
+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
+### 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
+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](
+- vp8enc crashes on 32 bit Windows, but was working fine in 1.6. 64 bit
+ Windows is unaffected.
+ [Bugzilla #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.
