All types before - that can be used together as a flags type as before, but from - that message onwards the types are just counted incrementally. - This was necessary to be able to add more message types. - In 2.0 GstMessageType will just become an enum and not a flags - type anymore. - • GstDeviceMonitor for device probing, e.g. to list all available - audio or video capture devices. This is the replacement for - GstPropertyProbe from 0.10. - • Events accumulate the running-time offset now when travelling - through pads, as set by the gst_pad_set_offset() function. This - allows to compensate for this in the QOS event for example. - • GstBuffer has a new flag "tag-memory" that is set automatically - when memory is added or removed to a buffer. This allows buffer - pools to detect if they can recycle a buffer or need to reset - it first. - • GstToc has new API to mark GstTocEntries as loops. - • A not-authorized resource error has been defined to notify - applications that accessing the resource has failed because - of missing authorization and to distinguish this case from others. - This change is actually already in 1.2.4. - • GstPad has a new flag "accept-intersect", that will let the default - ACCEPT_CAPS query handler do an intersection instead of subset check. - This is interesting for parser elements that can handle incomplete - caps. - • GstCollectPads has support for flushing and a default handler for - SEEK events now. - • New GstFlowAggregator helper object that simplifies handling of - flow returns in elements with multiple source pads. Additionally - GstPad now always stores the last flow return and provides an - API to retrieve it. - • GstSegment has new API to offset the running time by a specific - value and this is used in GstPad to allow positive and negative - offsets in gst_pad_set_offset() in all situations. - • Support for h265/HEVC and VP8 has been added to the codec utils and codec - parsers library, and was integrated into various elements. - • API for adjusting the TLS validation of RTSP connection has been added. - • The RTSP and SDP library has MIKEY (RFC 3830) support now, and - there is API to distinguish between the different RTSP profiles. - • API to access RTP time information and statistics. - • Support for auxiliary streams was added to rtpbin. - • Support for tiled, raw video formats has been added. - • GstVideoDecoder and GstAudioDecoder have API to help aggregating tag - events and merge custom tags into them consistently. - • GstBufferPool has support for flushing now. - • playbin/playsink has support for application provided audio and video - filters. - • GstDiscoverer has new and simplified API to get details about missing - plugins and information to pass to the plugin installer. - • The GL library was merged from gst-plugins-gl to gst-plugins-bad, - providing a generic infrastructure for handling GL inside GStreamer - pipelines and a plugin with some elements using these, especially - a video sink. Supported platforms currently are Android, Cocoa (OS X), - DispManX (Raspberry Pi), EAGL (iOS), WGL (Windows) and generic X11, - Wayland and EGL platforms. - This replaces eglglessink and also is supposed to replace osxvideosink. - • New GstAggregator base class in gst-plugins-bad. This is supposed to - replace GstCollectPads in the future and fix long-known shortcomings - in its API. Together with the base class some elements are provided - already, like a videomixer (compositor). +This release has been in the works for more than a year and is packed with new +features, bug fixes and other improvements. +See http://gstreamer.freedesktop.org/releases/1.6/ for the full list of +changes. -Major changes: - • New plugins and elements: - ∘ v4l2videodec element for accessing hardware codecs on - platforms that make them accessible via V4L2, e.g. - Samsung Exynos. This comes together with major refactoring - of the existing V4L2 elements and the corresponding - infrastructure. - The v4l2videodec element replaces the mfcdec element. - ∘ New downloadbuffer element that replaces the download - buffering feature of queue2. Compared to queue2's code - it is much simpler and only for this single use case. - A noteworthy new feature is that it's downloading gaps - in the already downloaded stream parts when nothing else - is to be downloaded. - This is now used by playbin when download buffering is - enabled. - ∘ rtpstreampay and rtpstreamdepay elements for transmitting - RTP packets over a stream API (e.g. TCP) according to - RFC 4571. - ∘ rtprtx elements for standard compliant implementation of - retransmissions, integrated into the rtpmanager plugin. - ∘ audiomixer element that mixes multiple audio streams together - into a single one while keeping synchronization. This is - planned to become the replacement of the adder element. - ∘ OpenNI2 plugin for 3D cameras like the Kinect camera. - ∘ OpenEXR plugin for decoding high-dynamic-range EXR images. - ∘ curlsshsink and curlsftpsink to write files via SSH/SFTP. - ∘ videosignal, ivfparse and sndfile plugins ported from 0.10. - ∘ avfvideosrc, vtdec and other elements were ported from 0.10 and - are available on OS X and iOS now. +Highlights - • Other changes: - ∘ gst-libav now uses libav 10.1, and gained support for H265/HEVC. - ∘ Support for hardware codecs and special memory types has been - improved with bugfixes and feature additions in various plugins - and base classes. - ∘ Various bugfixes and improvements to buffering in queue2 and - multiqueue elements. - ∘ dvbsrc supports more delivery mechanisms and other features - now, including DVB S2 and T2 support. - ∘ The MPEGTS library has support for many more descriptors. - ∘ Major improvements to tsdemux and tsparse, especially time and - seeking related. - ∘ souphttpsrc now has support for keep-alive connections, - compression, configurable number of retries and configuration - for SSL certificate validation. - ∘ hlsdemux has undergone major refactoring and works more - reliable now and supports more HLS features like trick modes. - Also fragments are pushed downstream while they're downloaded - now instead of waiting for each fragment to finish. - ∘ dashdemux and mssdemux are now also pushing fragments downstream - while they're downloaded instead of waiting for each fragment to - finish. - ∘ videoflip can automatically flip based on the orientation tag. - ∘ openjpeg supports the OpenJPEG2 API. - ∘ waylandsink was refactored and should be more useful now. It also - includes a small library which most likely is going to be removed - in the future and will result in extensions to the GstVideoOverlay - interface. - ∘ gst-rtsp-server supports SRTP and MIKEY now. - ∘ gst-libav encoders are now negotiating any profile/level settings - with downstream via caps. - ∘ Lots of fixes for coverity warnings all over the place. - ∘ Negotiation related performance improvements. - ∘ 500+ fixed bug reports, and many other bug fixes and other - improvements everywhere that had no bug report. +- Stereoscopic 3D and multiview video support +- Trick mode API for key-frame only fast-forward/fast-reverse playback etc. +- Improved DTS (decoding timestamp) vs. PTS (presentation timestamp) handling + to account for negative DTS +- New GstVideoConverter API for more optimised and more correct conversion of + raw video frames between all supported formats, with rescaling +- v4l2src now supports renegotiation +- v4l2transform can now do scaling +- V4L2 Element now report Colorimetry properly +- Easier chunked recording of MP4, Matroska, Ogg, MPEG-TS: new splitmuxsink + and multifilesink improvements +- Content Protection signalling API and Common Encryption (CENC) support for + DASH/MP4 +- Many adaptive streaming (DASH, HLS and MSS) improvements +- New PTP and NTP network client clocks and better remote clock tracking + stability +- High-quality text subtitle overlay at display resolutions with glimagesink + or gtkglsink +- RECORD support for the GStreamer RTSP Server +- Retransmissions (RTX) support in RTSP server and client +- RTSP seeking support in client and server has been fixed +- RTCP scheduling improvements and reduced size RTCP support +- MP4/MOV muxer acquired a new "robust" mode of operation which attempts to + keep the output file in a valid state at all times +- Live mixing support in aggregator, audiomixer and compositor was improved a + lot +- compositor now supports rescaling and converting inputs streams on the fly +- New audiointerleave element with proper input synchronisation and live input + support +- Blackmagic Design DeckLink capture and playback card support was rewritten + from scratch; 2k/4k support; mode sensing +- KLV metadata support in RTP and MPEG-TS +- H.265 video encoder (x265), decoders (libav, libde265) and RTP payloader and + depayloaders +- New DTLS plugin and SRTP/DTLS support +- OpenGL3 support, multiple contexts and context propagation, 3D video, + transfer/conversion separation, subtitle blending +- New OpenGL-based QML video sink, Gtk GL video sink, CoreAnimation + CAOpenGLLayerSink video sink +- gst-libav switched to ffmpeg as libav-provider, gains support for + 3D/multiview video, trick modes, and the CAVS codec +- GstHarness API for unit tests +- gst-editing-services got a completely new ges-launch-1.0 interface, improved + mixing support and integration into gst-validate +- gnonlin has been deprecated in favor of nle (Non Linear Engine) in + gst-editing-services +- gst-validate has a new plugin system, an extensive default testsuite, + support for concurrent test runs and valgrind support +- cerbero build tool for SDK binary packages gains new 'bundle-source' command +- Various improvements to the Android, iOS, OS X and Windows platform support -Things to look out for: - • The eglglessink element was removed and replaced by the glimagesink - element. - • The mfcdec element was removed and replaced by v4l2videodec. - • osxvideosink is only available in OS X 10.6 or newer. - • The GstDeviceMonitor API will likely change slightly before the - 1.4.0 release.
