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. - -[gst_info_vasprintf]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/gstreamer-GstInfo.html#gst-info-vasprintf -[gst_info_strdup_vprintf]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/gstreamer-GstInfo.html#gst-info-strdup-vprintf -[gst_info_strdup_printf]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/gstreamer-GstInfo.html#gst-info-strdup-printf - -### 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. - -[tracer-0]: https://gstconf.ubicast.tv/videos/a-new-tracing-subsystem-for-gstreamer/ -[tracer-1]: https://gstconf.ubicast.tv/videos/analyzing-caps-negotiation-using-gsttracer/ -[tracer-2]: http://blog.thiagoss.com/2015/07/23/gsttracer-experiments/ -[tracer-3]: https://git.gnome.org/browse/gst-debugger - -### 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-api]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-bad-libs/html/player.html -[gstplayer-talk]: https://gstconf.ubicast.tv/videos/gstplayer-a-simple-cross-platform-api-for-all-your-media-playback-needs-part-1/ -[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. - -[audio-0]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-libs/html/gst-plugins-base-libs-GstAudioConverter.html -[audio-1]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-libs/html/gst-plugins-base-libs-GstAudioQuantize.html -[audio-2]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-libs/html/gst-plugins-base-libs-gstaudiochannels.html#gst-audio-channel-mix-new -[audio-3]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-libs/html/gst-plugins-base-libs-gstaudiochannels.html#gst-audio-channel-get-fallback-mask -[audio-4]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-libs/html/gst-plugins-base-libs-gstaudiometa.html#GstAudioClippingMeta - -### 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) - -## Contributors - -Adam Miartus, Alban Bedel, Aleix Conchillo Flaqué, Aleksander Wabik, -Alessandro Decina, Alex Ashley, Alex Dizengof, Alex Henrie, Alistair Buxton, -Andreas Cadhalpun, Andreas Frisch, André Draszik, Anthony G.
