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 10.2, 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.
