GStreamer Changelog

New in version 1.4.4

November 10th, 2014
  • Bugs fixed in this release:
  • 737498 : multiqueue: doesn't take GAP event into account when calculating current level
  • 737794 : multiqueue: deadlock if queue overruns with serialized events
  • 737999 : systemclock: multi-thread entry status issue
  • 738198 : multiqueue: Does not wake up not-linked streams on EOS

New in version 1.4.1 (August 28th, 2014)

  • The 1.4 release series is adding new features on top of the 1.2 series and is part of the API and ABI-stable 1.x release series of the GStreamer multimedia framework that contains new features. The 1.4.x bugfix releases only contain important bugfixes compared to 1.4.0.

New in version 1.4 RC2 (July 12th, 2014)

  • The GStreamer team is pleased to announce the second release candidate of the stable 1.4 release series. The 1.4 release series is adding new features on top of the 1.0 and 1.2 series and is part of the API and ABI-stable 1.x release series of the GStreamer multimedia framework.
  • This release candidate will hopefully shortly be followed by the stable 1.4.0 release if no bigger regressions or bigger issues are detected, and enough testing of the release candidate happened. The new API that was added during the 1.3 release series is not expected to change anymore at this point.

New in version 1.4 RC1 (June 30th, 2014)

  • New API:
  • GstMessageType has GST_MESSAGE_EXTENDED added. 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).
  • 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.
  • 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.
  • 800+ fixed bug reports, and many other bug fixes and other improvements everywhere that had no bug report.
  • 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.
  • On Android the namespace of the automatically generated Java class for initialization of GStreamer has changed from com.gstreamer to org.freedesktop.gstreamer to prevent namespace pollution.
  • On iOS you have to update your gst_ios_init.h and gst_ios_init.m in your projects from the one included in the binaries if you used the GnuTLS GIO module before. The loading mechanism has slightly changed.

New in version 1.2.2 (December 28th, 2013)

  • The 1.2 release series is adding new features on top of the 1.0 series and is part of the API and ABI-stable 1.x release series of the GStreamer multimedia framework that contains new features.

New in version 1.2.0 (September 25th, 2013)

  • New API:
  • GstContext negotiation / sharing / announcing for sharing a generic context between elements, e.g. a display handle
  • GL texture upload conversion meta for allowing different buffer types to be converted to an OpenGL texture
  • GstCapsFeatures as extension to GstCaps for allowing the negotiation of specific memory or meta requirements between elements
  • GstMemory flags for contiguous and non-mappable memory

  • insertbin library for easier handling of dynamically linked pipelines (in -bad for now)
  • EGL helper library (in -bad for now)
  • MPEG-TS data structure library (in -bad for now)
  • New GstVideoRegionOfInterestMeta to describe a region of interest on video frames.
  • GstVideoDecoder/Encoder has new ::flush() vfunc to replace the ill-defined ::reset() vfunc.
  • The URI query allows to query the redirected URI now.
  • Major changes:
  • New tool: gst-play-1.0 in gst-plugins-base for basic playback testing on the command line.
  • New plugins:
  • mssdemux for Microsoft Smooth Streaming
  • dashdemux for DASH adaptive streaming protocol
  • bluez for interaction with Bluetooth devices
  • openjpeg for JPEG2000 decoding and encoding
  • daala for experimental Daala decoding and encoding
  • vpx plugin has experimental VP9 decoding and encoding support
  • webp plugin for WebP decoding (encoding to be added later)
  • Various others: yadif, srtp, sbc, fluidsynth, midiparse, mfc, ivtv, accuraterip and audiofxbad
  • Moved plugins:
  • dtmf, vp8rtp, scaletempo and rtpmux plugins are in gst-plugins-good now
  • Video:
  • Fix handling of interlaced video in converters such as videoscale and videoconvert (e.g. scale both fields independently)
  • videoconvert will try harder to minimise quality losses when conversion is necessary
  • The experimental GstSurfaceConverter, GstSurfaceMeta and GstVideoContext APIs from the (confusingly-named) libgstbasevideo-1.0 library in gst-plugins-bad have now been removed and been replaced by new APIs in GStreamer Core and gst-plugins-base (see above). Since that was all that was left in this library, the entire experimental libgstbasevideo-1.0 library has been removed from gst-plugins-bad
  • Chroma subsampling and chroma siting conversion is better handled in videoconvert and the support for interlaced video was improved.
  • New pinwheel and spoke patterns in videotestsrc
  • videomixer can now accept different video formats on its sinkpads and converts to a common format during mixing
  • Audio:
  • audioconvert will try harder to minimise quality losses when conversion is necessary
  • adder now allows muting/unmuting of its input streams, and also per-input stream volume
  • pulseaudio elements can switch between devices during playback now
  • aacparse can convert between ADTS←→RAW
  • Platform specific changes:
  • Caps, events, etc. are now printed in the GStreamer debug logs with their content instead of just the pointer address even on non-glibc platforms (e.g. Windows, OSX, Android).
  • Network elements (UDP/TCP) now work better with platforms, where IPv6 sockets can't handle IPv4 (e.g. Windows)
  • Linux/BSD: v4l2 had many improvements and cleanups
  • Other changes:
  • gst-libav now uses libav 9
  • Static linking of plugins is supported now (also in 1.0.7)
  • rtspsrc: add support for NetClientClock: when the server suggests a GstNetTimeProvider in the SDP, set up a GstNetClientClock that slaves to the remote clock and suggest this clock in provide_clock. Simplifies synchronized playback of a resource from an RTSP server. gst-rtsp-server now supports adding this to the SDP and can provide a network clock
  • RTP retransmission / NACK support and big RTP jitterbuffer improvements
  • SRTP and DTLS support
  • Changes to many elements and core to use the correct sticky event order and also not lose any important sticky events during flushing
  • >1000 fixed bug reports, and many other bug fixes and other improvements everywhere that had no bug report
  • Things to look out for:
  • Single header includes for all libraries, e.g. #include - this was needed for some bindings.
  • Stricter (correct) caps subset checking in some cases where this was not correct before. Caps will now always fail to be a compatible subset of another set of caps if the subset caps are missing some fields that the superset caps have. This might lead to not-negotiated errors if caps are incomplete now. However, it also prevents possible data corruption caused by piping data formatted in an incompatible/unexpected way into some elements. Check your h264 caps for stream-format and alignment fields and AAC caps for the stream-format field. This change will also be included in the next stable 1.0.8 release.
  • Stricter checking for missing events and correct sticky event order (stream-start, caps, segment) in some places; this is not enabled in stable releases by default, but you may get warnings when using git builds, development releases or when compiling with -UG_DISABLE_ASSERT in CFLAGS
  • x264enc now outputs data in byte-stream by default if downstream has ANY caps (e.g. appsink without caps set, filesink, udpsink, tcpserversink etc.)
  • The MPEG TS demuxer posts messages contain the PMT, PAT, etc. in a different format now. This new format uses the data structures from the new MPEGTS library
  • The GstContext API has changed between 1.1.4 and 1.1.90
