+
+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 10.2, 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.
