It is scheduled for release in +March 2019. + +1.15.x is the unstable development version that is being developed in +the git master branch and which will eventually result in 1.16. + +1.16 will be backwards-compatible to the stable 1.14, 1.12, 1.10, 1.8, +1.6, 1.4, 1.2 and 1.0 release series. + +See https://gstreamer.freedesktop.org/releases/1.16/ for the latest +version of this document. + +_Last updated: Wednesday 27 January 2019, 00:30 UTC (log)_ + + +Introduction + +The GStreamer team is proud to announce a new major feature release in +the stable 1.x API series of your favourite cross-platform multimedia +framework! + +As always, this release is again packed with many new features, bug +fixes and other improvements. + + +Highlights + +- GStreamer WebRTC stack gained support for data channels for + peer-to-peer communication based on SCTP, BUNDLE support, as well as + support for multiple TURN servers. + +- AV1 video codec support for Matroska and QuickTime/MP4 containers + and more configuration options and supported input formats for the + AOMedia AV1 encoder + +- Support for Closed Captions and other Ancillary Data in video + +- Support for planar (non-interleaved) raw audio + +- GstVideoAggregator, compositor and OpenGL mixer elements are now in + -base + +- New alternate fields interlace mode where each buffer carries a + single field + +- WebM and Matroska ContentEncryption support in the Matroska demuxer + +- new WebKit WPE-based web browser source element + +- Video4Linux: HEVC encoding and decoding, JPEG encoding, and improved + dmabuf import/export + +- Hardware-accelerated Nvidia video decoder gained support for VP8/VP9 + decoding, whilst the encoder gained support for H.265/HEVC encoding. + +- Many improvements to the Intel Media SDK based hardware-accelerated + video decoder and encoder plugin (msdk): dmabuf import/export for + zero-copy integration with other components; VP9 decoding; 10-bit + HEVC encoding; video post-processing (vpp) support including + deinterlacing; and the video decoder now handles dynamic resolution + changes. + +- The ASS/SSA subtitle overlay renderer can now handle multiple + subtitles that overlap in time and will show them on screen + simultaneously + +- The Meson build is now feature-complete (*) and it is now the + recommended build system on all platforms. The Autotools build is + scheduled to be removed in the next cycle. + +- The GStreamer Rust bindings and Rust plugins module are now + officially part of upstream GStreamer. + +- Many performance improvements + + +Major new features and changes + +Noteworthy new API + +- GstAggregator has a new "min-upstream-latency" property that forces + a minimum aggregate latency for the input branches of an aggregator. + This is useful for dynamic pipelines where branches with a higher + latency might be added later after the pipeline is already up and + running and where a change in the latency would be disruptive. This + only applies to the case where at least one of the input branches is + live though, it won’t force the aggregator into live mode in the + absence of any live inputs. + +- GstBaseSink gained a "processing-deadline" property and + setter/getter API to configure a processing deadline for live + pipelines. The processing deadline is the acceptable amount of time + to process the media in a live pipeline before it reaches the sink. + This is on top of the systemic latency that is normally reported by + the latency query. This defaults to 20ms and should make pipelines + such as v4l2src ! xvimagesink not claim that all frames are late in + the QoS events. Ideally, this should replace the "max-lateness" + property for most applications. + +- RTCP Extended Reports (XR) parsing according to RFC 3611: + Loss/Duplicate RLE, Packet Receipt Times, Receiver Reference Time, + Delay since the last Receiver (DLRR), Statistics Summary, and VoIP + Metrics reports. This only provides the ability to parse such + packets, generation of XR packets is not supported yet and XR + packets are not automatically parsed by rtpbin / rtpsession but must + be actively handled by the application. + +- a new mode for interlaced video was added where each buffer carries + a single field of interlaced video, with buffer flags indicating + whether the field is the top field or bottom field. Top and bottom + fields are expected to alternate in this mode. Caps for this + interlace mode must also carry a format:Interlaced caps feature to + ensure backwards compatibility. + +- The video library has gained support for three new raw pixel + formats: + + - Y410: packed 4:4:4 YUV, 10 bits per channel + - Y210: packed 4:2:2 YUV, 10 bits per channel + - NV12_10LE40: fully-packed 10-bit variant of NV12_10LE32, + i.e. without the padding bits + +- GstRTPSourceMeta is a new meta that can be used to transport + information about the origin of depayloaded or decoded RTP buffers, + e.g. when mixing audio from multiple sources into a single stream. A + new "source-info" property on the RTP depayloader base class + determines whether depayloaders should put this meta on outgoing + buffers. Similarly, the same property on RTP payloaders determines + whether they should use the information from this meta to construct + the CSRCs list on outgoing RTP buffers. + +- gst_sdp_message_from_text() is a convenience constructor to parse + SDPs from a string which is particularly useful for language + bindings. + +Support for Planar (Non-Interleaved) Raw Audio + +Raw audio samples are usually passed around in interleaved form in +GStreamer, which means that if there are multiple audio channels the +samples for each channel are interleaved in memory, e.g. +|LEFT|RIGHT|LEFT|RIGHT|LEFT|RIGHT| for stereo audio. A non-interleaved +or planar arrangement in memory would look like +|LEFT|LEFT|LEFT|RIGHT|RIGHT|RIGHT| instead, possibly with +|LEFT|LEFT|LEFT| and |RIGHT|RIGHT|RIGHT| residing in separate memory +chunks or separated by some padding. + +GStreamer has always had signalling for non-interleaved audio since +version 1.0, but it was never actually properly implemented in any +elements. audioconvert would advertise support for it, but wasn’t +actually able to handle it correctly. + +With this release we now have full support for non-interleaved audio as +well, which means more efficient integration with external APIs that +handle audio this way, but also more efficient processing of certain +operations like interleaving multiple 1-channel streams into a +multi-channel stream which can be done without memory copies now. + +New API to support this has been added to the GStreamer Audio support +library: There is now a new GstAudioMeta which describes how data is +laid out inside the buffer, and buffers with non-interleaved audio must +always carry this meta. To access the non-interleaved audio samples you +must map such buffers with gst_audio_buffer_map() which works much like +gst_buffer_map() or gst_video_frame_map() in that it will populate a +little GstAudioBuffer helper structure passed to it with the number of +samples, the number of planes and pointers to the start of each plane in +memory. This function can also be used to map interleaved audio buffers +in which case there will be only one plane of interleaved samples. + +Of course support for this has also been implemented in the various +audio helper and conversion APIs, base classes, and in elements such as +audioconvert, audioresample, audiotestsrc, audiorate. + +Support for Closed Captions and Other Ancillary Data in Video + +The video support library has gained support for detecting and +extracting Ancillary Data from videos as per the SMPTE S291M +specification, including: + +- a VBI (Vertical Blanking Interval) parser that can detect and + extract Ancillary Data from Vertical Blanking Interval lines of + component signals. This is currently supported for videos in v210 + and UYVY format. + +- a new GstMeta for closed captions: GstVideoCaptionMeta. This + supports the two types of closed captions, CEA-608 and CEA-708, + along with the four different ways they can be transported (other + systems are a superset of those). + +- a VBI (Vertical Blanking Interval) encoder for writing ancillary + data to the Vertical Blanking Interval lines of component signals. + +The new closedcaption plugin in gst-plugins-bad then makes use of all +this new infrastructure and provides the following elements: + +- cccombiner: a closed caption combiner that takes a closed captions + stream and another stream and adds the closed captions as + GstVideoCaptionMeta to the buffers of the other stream. + +- ccextractor: a closed caption extractor which will take + GstVideoCaptionMeta from input buffers and output them as a separate + closed captions stream. + +- ccconverter: a closed caption converter that can convert between + different formats + +- line21decoder: extract line21 closed captions from SD video streams + +- cc708overlay: decodes CEA 608/708 captions and overlays them on + video + +Additionally, the following elements have also gained Closed Caption +support: + +- qtdemux and qtmux support CEA 608/708 Closed Caption tracks + +- mpegvideoparse extracts Closed Captions from MPEG-2 video streams + +- decklinkvideosink can output closed captions and decklinkvideosrc + can extract closed captions + +- playbin and playbin3 learned how to autoplug CEA 608/708 CC overlay + elements + +- the externally maintained ajavideosrc element for AJA capture cards + has support for extracting closed captions + +The rsclosedcaption plugin in the Rust plugins collection includes a +MacCaption (MCC) file parser and encoder. + +New Elements + +- overlaycomposition: New element that allows applications to draw + GstVideoOverlayCompositions on a stream. The element will emit the + "draw" signal for each video buffer, and the application then + generates an overlay for that frame (or not). This is much more + performant than e.g. cairooverlay for many use cases, e.g. because + pixel format conversions can be avoided or the blitting of the + overlay can be delegated to downstream elements (such as + gloverlaycompositor). It’s particularly useful for cases where only + a small section of the video frame should be drawn on. + +- gloverlaycompositor: New OpenGL-based compositor element that + flattens any overlays from GstVideoOverlayCompositionMetas into the + video stream. This element is also always part of glimagesink. + +- glalpha: New element that adds an alpha channel to a video stream. + The values of the alpha channel can either be set to a constant or + can be dynamically calculated via chroma keying. It is similar to + the existing alpha element but based on OpenGL. Calculations are + done in floating point so results may not be identical to the output + of the existing alpha element. + +- rtpfunnel funnels together RTP streams into a single session. Use + cases include multiplexing and bundle. webrtcbin uses it to + implement BUNDLE support. + +- testsrcbin is a source element that provides an audio and/or video + stream and also announces them using the recently-introduced + GstStream API. This is useful for testing elements such as playbin3 + or uridecodebin3 etc. + +- New closed caption elements: cccombiner, ccextractor, ccconverter, + line21decoder and cc708overlay (see above) + +- wpesrc: new source element acting as a Web Browser based on WebKit + WPE + +- Two new OpenCV-based elements: cameracalibrate and cameraundistort + that can communicate to figure out distortion correction parameters + for a camera and correct for the distortion. + +- New sctp plugin based on usrsctp with sctpenc and sctpdec elements. + These elements are used inside webrtcbin for implementing data + channels. + +New element features and additions + +- playbin3, playbin and playsink have gained a new "text-offset" + property to adjust the positioning of the selected subtitle stream + vis-a-vis the audio and video streams. This uses subtitleoverlay’s + new "subtitle-ts-offset" property. GstPlayer has gained matching API + for this, namely gst_player_get_text_video_offset(). + +- playbin3 buffering improvements: in network playback scenarios there + may be multiple inputs to decodebin3, and buffering will be done + before decodebin3 using queue2 or downloadbuffer elements inside + urisourcebin. Since this is before any parsers or demuxers there may + not be any bitrate information available for the various streams, so + it was difficult to configure the buffering there smartly within + global constraints. This was improved now: The queue2 elements + inside urisourcebin will now use the new bitrate query to figure out + a bitrate estimate for the stream if no bitrate was provided by + upstream, and urisourcebin will use the bitrates of the individual + queues to distribute the globally-set "buffer-size" budget in bytes + to the various queues. urisourcebin also gained "low-watermark" and + "high-watermark" properties which will be proxied to the internal + queues, as well as a read-only "statistics" property which allows + querying of the minimum/maximum/average byte and time levels of the + queues inside the urisourcebin in question. + +- splitmuxsink has gained a couple of new features: + + - new "async-finalize" mode: This mode is useful for muxers or + outputs that can take a long time to finalize a file. Instead of + blocking the whole upstream pipeline while the muxer is doing + its stuff, we can unlink it and spawn a new muxer + sink + combination to continue running normally. This requires us to + receive the muxer and sink (if needed) as factories via the new + "muxer-factory" and "sink-factory" properties, optionally + accompanied by their respective properties structures (set via + the new "muxer-properties" and "sink-properties" properties). + There are also new "muxer-added" and "sink-added" signals in + case custom code has to be called for them to configure them. + + - "split-at-running-time" action signal: When called by the user, + this action signal ends the current file (and starts a new one) + as soon as the given running time is reached. If called multiple + times, running times are queued up and processed in the order + they were given. + + - "split-after" action signal to finish outputting the current GOP + to the current file and then start a new file as soon as the GOP + is finished and a new GOP is opened (unlike the existing + "split-now" which immediately finishes the current file and + writes the current GOP into the next newly-started file). + + - "reset-muxer" property: when unset, the muxer is reset using + flush events instead of setting its state to NULL and back. This + means the muxer can keep state across resets, e.g. mpegtsmux + will keep the continuity counter continuous across segments as + required by hlssink2. + +- qtdemux gained PIFF track encryption box support in addition to the + already-existing PIFF sample encryption support, and also allows + applications to select which encryption system to use via a + "drm-preferred-decryption-system-id" context in case there are + multiple options. + +- qtmux: the "start-gap-threshold" property determines now whether an + edit list will be created to account for small gaps or offsets at + the beginning of a stream in case the start timestamps of tracks + don’t line up perfectly. Previously the threshold was hard-coded to + 1% of the (video) frame duration, now it is 0 by default (so edit + list will be created even for small differences), but fully + configurable. + +- rtpjitterbuffer has improved end-of-stream handling + +- rtpmp4vpay will be prefered over rtpmp4gpay for MPEG-4 video in + autoplugging scenarios now + +- rtspsrc now allows applications to send RTSP SET_PARAMETER and + GET_PARAMETER requests using action signals. + +- rtspsrc has a small (100ms) configurable teardown delay by default + to try and make sure an RTSP TEARDOWN request gets sent out when the + source element shuts down. This will block the downward PAUSED to + READY state change for a short time, but can be disabled where it’s + a problem. Some servers only allow a limited number of concurrent + clients, so if no proper TEARDOWN is sent new clients may have + problems connecting to the server for a while. + +- souphttpsrc behaves better with low bitrate streams now. Before it + would increase the read block size too quickly which could lead to + it not reading any data from the socket for a very long time with + low bitrate streams that are output live downstream. This could lead + to servers kicking off the client. + +- filesink: do internal buffering to avoid performance regression with + small writes since we bypass libc buffering by using writev() + instead of fwrite() + +- identity: add "eos-after" property and fix "error-after" property + when the element is reused + +- input-selector: lets context queries pass through, so that + e.g. upstream OpenGL elements can use contexts and displays + advertised by downstream elements + +- queue2: avoid ping-pong between 0% and 100% buffering messages if + upstream is pushing buffers larger than one of its limits, plus + performance optimisations + +- opusdec: new "phase-inversion" property to control phase inversion. + When enabled, this will slightly increase stereo quality, but + produces a stream that when downmixed to mono will suffer audio + distortions. + +- The x265enc HEVC encoder also exposes a "key-int-max" property to + configure the maximum allowed GOP size now. + +- decklinkvideosink has seen stability improvements for long-running + pipelines (potential crash due to overflow of leaked clock refcount) + and clock-slaving improvements when performing flushing seeks + (causing stalls in the output timeline), pausing and/or buffering. + +- srtpdec, srtpenc: add support for MKIs which allow multiple keys to + be used with a single SRTP stream + +- The srt Secure Reliable Transport plugin has integrated server and + client elements srt{client,server}{src,sink} into one (srtsrc and + srtsink), since SRT connection mode can be changed by uri + parameters. + +- h264parse and h265parse will handle SEI recovery point messages and + mark recovery points as keyframes as well (in addition to IDR + frames) + +- webrtcbin: "add-turn-server" action signal to pass multiple ICE + relays (TURN servers). + +- The removesilence element has received various new features and + properties, such as a "threshold" property, detecting silence only + after minimum silence time/buffers, a "silent" property to control + bus message notifications as well as a "squash" property. + +- AOMedia AV1 decoder gained support for 10/12bit decoding whilst the + AV1 encoder supports more image formats and subsamplings now and + acquired support for rate control and profile related configuration. + +- The Fraunhofer fdkaac plugin can now be built against the 2.0.0 + version API and has improved multichannel support + +- kmssink now supports unpadded 24-bit RGB and can configure mode + setting from video info, which enables display of multi-planar + formats such as I420 or NV12 with modesetting. It has also gained a + number of new properties: The "restore-crtc" property does what it + says on the tin and is enabled by default. "plane-properties" and + "connector-properties" can be used to pass custom properties to the + DRM. + +- waylandsink has a "fullscreen" property now. + +Plugin and library moves + +- The stereo element was moved from -bad into the existing audiofx + plugin in -good. If you get duplicate type registration warnings + when upgrading, check that you don’t have a stale stereoplugin lying + about somewhere. + +GstVideoAggregator, compositor, and OpenGL mixer elements moved from -bad to -base + +GstVideoAggregator is a new base class for raw video mixers and muxers +and is based on GstAggregator. It provides defined-latency mixing of raw +video inputs and ensures that the pipeline won’t stall even if one of +the input streams stops producing data. + +As part of the move to stabilise the API there were some last-minute API +changes and clean-ups, but those should mostly affect internal elements. +Most notably, the "ignore-eos" pad property was renamed to +"repeat-after-eos" and the conversion code was moved to a +GstVideoAggregatorConvertPad subclass to avoid code duplication, make +things less awkward for subclasses like the OpenGL-based video mixer, +and make the API more consistent with the audio aggregator API. + +It is used by the compositor element, which is a replacement for +‘videomixer’ which did not handle live inputs very well. compositor +should behave much better in that respect and generally behave as one +would expected in most scenarios. + +The compositor element has gained support for per-pad blending mode +operators (SOURCE, OVER, ADD) which determines what operator to use for +blending this pad over the previous ones. This can be used to implement +crossfading and the available operators can be extended in the future as +needed. + +A number of OpenGL-based video mixer elements (glvideomixer, glmixerbin, +glvideomixerelement, glstereomix, glmosaic) which are built on top of +GstVideoAggregator have also been moved from -bad to -base now. These +elements have been merged into the existing OpenGL plugin, so if you get +duplicate type registration warnings when upgrading, check that you +don’t have a stale openglmixers plugin lying about somewhere. + +Plugin removals + +The following plugins have been removed from gst-plugins-bad: + +- The experimental daala plugin has been removed, since it’s not so + useful now that all effort is focused on AV1 instead, and it had to + be enabled explicitly with --enable-experimental anyway. + +- The spc plugin has been removed. It has been replaced by the gme + plugin. + +- The acmmp3dec and acmenc plugins for Windows have been removed. ACM + is an ancient legacy API and there was no point in keeping the + plugins around for a licensed MP3 decoder now that the MP3 patents + have expired and we have a decoder in -good. We also didn’t ship + these in our cerbero-built Windows packages, so it’s unlikely that + they’ll be missed. + + +Miscellaneous API additions + +- GstBitwriter: new generic bit writer API to complement the existing + bit reader + +- gst_buffer_new_wrapped_bytes() creates a wrap buffer from a GBytes + +- gst_caps_set_features_simple() sets a caps feature on all the + structures of a GstCaps + +- New GST_QUERY_BITRATE query: This allows determining from downstream + what the expected bitrate of a stream may be which is useful in + queue2 for setting time based limits when upstream does not provide + timing information. tsdemux, qtdemux and matroskademux have basic + support for this query on their sink pads. + +- elements: there is a new “Hardware” class specifier. Elements + interacting with hardware devices should specify this classifier in + their element factory class metadata. This is useful to advertise as + one might need to put such elements into READY state to test if the + hardware is present in the system for example. + +- protection: Add a new definition for unspecified system protection, + GST_PROTECTION_UNSPECIFIED_SYSTEM_ID + +- take functions for various mini objects that didn’t have them yet: + gst_query_take(), gst_message_take(), gst_tag_list_take(), + gst_buffer_list_take(). Unlike the various _replace() functions + _take() does not increase the reference count but takes ownership of + the mini object passed. + +- clear functions for various mini object types and GstObject which + unrefs the object or mini object (if non-NULL) and sets the variable + pointed to to NULL: gst_clear_structure(), gst_clear_tag_list(), + gst_clear_query(), gst_clear_message(), gst_clear_event(), + gst_clear_caps(), gst_clear_buffer_list(), gst_clear_buffer(), + gst_clear_mini_object(), gst_clear_object() + +- miniobject: new API gst_mini_object_add_parent() and + gst_mini_object_remove_parent() to set parent pointers on mini + objects to ensure correct writability: Every container of + miniobjects now needs to store itself as parent in the child object, + and remove itself again later. A mini object is then only writable + if there is at most one parent, that parent is writable itself, and + the reference count of the mini object is 1. GstBuffer (for + memories), GstBufferList (for buffers), GstSample (for caps, buffer, + bufferlist), and GstVideoOverlayComposition were updated + accordingly. Without this it was possible to have e.g. a buffer list + with a refcount of 2 used in two places at once that both modify the + same buffer with refcount 1 at the same time wrongly thinking it is + writable even though it’s really not. + +- poll: add API to watch for POLLPRI and stop treating POLLPRI as a + read. This is useful to wait for video4linux events which are + signalled via POLLPRI. + +- sample: new API to update the contents of a GstSample and make it + writable: gst_sample_set_buffer(), gst_sample_set_caps(), + gst_sample_set_segment(), gst_sample_set_info(), plus + gst_sample_is_writable() and gst_sample_make_writable(). This makes + it possible to reuse a sample object and avoid unnecessary memory + allocations, for example in appsink. + +- ClockIDs now keep a weak reference to underlying clock to avoid + crashes in basesink in corner cases where a clock goes away while + the ClockID is still in use, plus some new API + (gst_clock_id_get_clock(), gst_clock_id_uses_clock()) to check the + clock a ClockID is linked to. + +- The GstCheck unit test library gained a + fail_unless_equals_clocktime() convenience macro as well as some new + GstHarness API for for proposing meta APIs from the allocation + query: gst_harness_add_propose_allocation_meta(). ASSERT_CRITICAL() + checks in unit tests are now skipped if GStreamer was compiled with + GST_DISABLE_GLIB_CHECKS. + +- gst_audio_buffer_truncate() convenience function to truncate a raw + audio buffer + + +Miscellaneous performance and memory optimisations + +As always there have been many performance and memory usage improvements +across all components and modules. Some of them (such as dmabuf +import/export) have already been mentioned elsewhere so won’t be +repeated here. + +The following list is only a small snapshot of some of the more +interesting optimisations that haven’t been mentioned in other contexts +yet: + +- The GstVideoEncoder and GstVideoDecoder base classes now release the + STREAM_LOCK when pushing out buffers, which means (multi-threaded) + encoders and decoders can now receive and continue to process input + buffers whilst waiting for downstream elements in the pipeline to + process the buffer that was pushed out. This increases throughput + and reduces processing latency, also and especially for + hardware-accelerated encoder/decoder elements. + +- GstQueueArray has seen a few API additions + (gst_queue_array_peek_nth(), gst_queue_array_set_clear_func(), + gst_queue_array_clear()) so that it can be used in other places like + GstAdapter instead of a GList, which reduces allocations and + improves performance. + +- appsink now reuses the sample object in pull_sample() if possible + +- rtpsession only starts the RTCP thread when it’s actually needed now + +- udpsrc uses a buffer pool now and the GstUdpSrc object structure was + optimised for better cache performance + +GstPlayer + +- API was added to fine-tune the synchronisation offset between + subtitles and video + + +Miscellaneous changes + +- As a result of moving to newer FFmpeg APIs, encoder and decoder + elements exposed by the GStreamer FFmpeg wrapper plugin (gst-libav) + may have seen possibly incompatible changes to property names and/or + types, and not all properties exposed might be functional. We are + still reviewing the new properties and aim to minimise breaking + changes at least for the most commonly-used properties, so please + report any issues you run into! + +OpenGL integration + +- The OpenGL mixer elements have been moved from -bad to + gst-plugins-base (see above) + +- The Mesa GBM backend now supports headless mode + +- gloverlaycompositor: New OpenGL-based compositor element that + flattens any overlays from GstVideoOverlayCompositionMetas into the + video stream. + +- glalpha: New element that adds an alpha channel to a video stream. + The values of the alpha channel can either be set to a constant or + can be dynamically calculated via chroma keying. It is similar to + the existing alpha element but based on OpenGL. Calculations are + done in floating point so results may not be identical to the output + of the existing alpha element. + +- glupload: Implement direct dmabuf uploader, the idea being that some + GPUs (like the Vivante series) can actually perform the YUV->RGB + conversion internally, so no custom conversion shaders are needed. + To make use of this feature, we need an additional uploader that can + import DMABUF FDs and also directly pass the pixel format, relying + on the GPU to do the conversion. + + +Tracing framework and debugging improvements + +- There is now a GDB PRETTY PRINTER FOR VARIOUS GSTREAMER TYPES: For + GstObject pointers the type and name is added, e.g. + 0x5555557e4110 [GstDecodeBin|decodebin0]. For GstMiniObject pointers + the object type is added, e.g. 0x7fffe001fc50 [GstBuffer]. For + GstClockTime and GstClockTimeDiff the time is also printed in human + readable form, e.g. 150116219955 [+0:02:30.116219955]. + +- GDB EXTENSION WITH TWO CUSTOM GDB COMMANDS gst-dot AND gst-print: + + - gst-dot creates dot files that a very close to what + GST_DEBUG_BIN_TO_DOT_FILE() produces, but object properties and + buffer contents such as codec-data in caps are not available. + + - gst-print produces high-level information about a GStreamer + object. This is currently limited to pads for GstElements and + events for the pads. The output may look like this: + + (gdb) gst-print pad.object.parent + GstMatroskaDemux (matroskademux0) { + SinkPad (sink, pull) { + } + SrcPad (video_0, push) { + events: + stream-start: + stream-id: 0463ccb080d00b8689bf569a435c4ff84f9ff753545318ae2328ea0763fd0bec/001:1274058367 + caps: video/x-theora + width: 1920 + height: 800 + pixel-aspect-ratio: 1/1 + framerate: 24/1 + streamheader: < 0x5555557c7d30 [GstBuffer], 0x5555557c7e40 [GstBuffer], 0x7fffe00141d0 [GstBuffer] > + segment: time + rate: 1 + tag: global + container-format: Matroska + } + SrcPad (audio_0, push) { + events: + stream-start: + stream-id: 0463ccb080d00b8689bf569a435c4ff84f9ff753545318ae2328ea0763fd0bec/002:1551204875 + caps: audio/mpeg + mpegversion: 4 + framed: true + stream-format: raw + codec_data: 0x7fffe0014500 [GstBuffer] + level: 2 + base-profile: lc + profile: lc + channels: 2 + rate: 44100 + segment: time + rate: 1 + tag: global + container-format: Matroska + tag: stream + audio-codec: MPEG-4 AAC audio + language-code: en + } + } + +- gst_structure_to_string() now serialises the actual value of + pointers when serialising GstStructures instead of claiming they’re + NULL. This makes debug logging in various places less confusing, + because it’s clear now that structure fields actually hold valid + objects. Such object pointer values will never be deserialised + however. + + +Tools + +- gst-inspect-1.0 has coloured output now and will automatically use a + pager if the output does not fit on a page. This only works in a + UNIX environment and if the output is not piped, and on Windows 10 + build 16257 or newer. If you don’t like the colours you can disable + them by setting the GST_INSPECT_NO_COLORS=1 environment variable or + passing the --no-color command line option. + + +GStreamer RTSP server + +- Improved backlog handling when using TCP interleaved for data + transport. Before there was a fixed maximum size for backlog + messages, which was prone to deadlocks and made it difficult to + control memory usage with the watch backlog. The RTSP server now + limits queued TCP data messages to one per stream, moving queuing of + the data into the pipeline and leaving the RTSP connection + responsive to RTSP messages in both directions, preventing all those + problems. + +- Initial ULP Forward Error Correction support in rtspclientsink and + for RECORD mode in the server. + +- API to explicitly enable retransmission requests (RTX) + +- Lots of multicast-related fixes + +- rtsp-auth: Add support for parsing .htdigest files + + +GStreamer VAAPI + +- this section will be filled in in due course + + +GStreamer OMX + +- Add support of NV16 format to video encoders input. + +- Video decoders now handle the ALLOCATION query to tell upstream + about the number of buffers they require.

The Autotools build is + scheduled to be removed in the next cycle. Developers who currently + use gst-uninstalled should move to gst-build. The build option + naming has been cleaned up and made consistent and there are now + feature options to enable/disable plugins and various other features + on a case-by-case basis. (*) with the exception of plugin docs which + will be handled differently in future + +- Symbol export in libraries is now controlled via explicit exports + using symbol visibility or export defines where supported, to ensure + consistency across all platforms. This also allows libraries to have + exports that vary based on detected platform features and configure + options as is the case with the GStreamer OpenGL integration library + for example. A few symbols that had been exported by accident in + earlier versions may no longer be exported. These symbols will not + have had declarations in any public header files then though and + would not have been usable. + +- The GStreamer FFmpeg wrapper plugin (gst-libav) now depends on + FFmpeg 4.x and uses the new FFmpeg 4.x API and stopped relying on + ancient API that was removed with the FFmpeg 4.x release. This means + that it is no longer possible to build this module against an older + system-provided FFmpeg 3.x version. Use the internal FFmpeg 4.x copy + instead if you build using autotools, or use gst-libav 1.14.x + instead which targets the FFmpeg 3.x API and _should_ work fine in + combination with a newer GStreamer. It’s difficult for us to support + both old and new FFmpeg APIs at the same time, apologies for any + inconvenience caused. + +- Hardware-accelerated Nvidia video encoder/decoder plugins nvdec and + nvenc can be built against CUDA Toolkit versions 9 and 10.0 now. The + dynlink interface has been dropped since it’s deprecated in 10.0. + +- The (optional) OpenCV requirement has been bumped to >= 3.0.0 and + the plugin can also be built against OpenCV 4.x now. + +- New sctp plugin based on usrsctp (for WebRTC data channels) + +Cerbero + +Cerbero is a meta build system used to build GStreamer plus dependencies +on platforms where dependencies are not readily available, such as +Windows, Android, iOS and macOS. + +Cerbero has seen a number of improvements: + +- Cerbero has been ported to Python 3 and requires Python 3.5 or newer + now + +- Source tarballs are now protected by checksums in the recipes to + guard against download errors and malicious takeover of projects or + websites. In addition, downloads are only allowed via secure + transports now and plain HTTP, FTP and git:// transports are not + allowed anymore. + +- There is now a new fetch-bootstrap command which downloads sources + required for bootstrapping, with an optional --build-tools-only + argument to match the bootstrap --build-tools-only command. + +- The bootstrap, build, package and bundle-source commands gained a + new --offline switch that ensures that only sources from the cache + are used and never downloaded via the network. This is useful in + combination with the fetch and fetch-bootstrap commands that acquire + sources ahead of time before any build steps are executed. This + allows more control over the sources used and when sources are + updated, and is particularly useful for build environments that + don’t have network access. + +- bootstrap --assume-yes will automatically say ‘yes’ to any + interactive prompts during the bootstrap stage, such as those from + apt-get or yum. + +- bootstrap --system-only will only bootstrap the system without build + tools. + +- Manifest support: The build manifest can be used in continuous + integration (CI) systems to fixate the Git revision of certain + projects so that all builds of a pipeline are on the same reference. + This is used in GStreamer’s gitlab CI for example. It can also be + used in order to re-produce a specific build. To set a manifest, you + can set manifest = 'my_manifest.xml' in your configuration file, or + use the --manifest command line option.

The 1.16.x bug-fix releases will be made from +the git 1.16 branch, which is a stable branch. + +1.16.0 + +1.16.0 is scheduled to be released in March 2019. + + +Known Issues + +- possibly breaking/incompatible changes to properties of wrapped + FFmpeg decoders and encoders (see above). + +- The way that GIO modules are named has changed due to upstream GLib + natively adding support for loading static GIO modules. This means + that any GStreamer application using gnutls for SSL/TLS on the + Android or iOS platforms (or any other setup using static libraries) + will fail to link looking for the g_io_module_gnutls_load_static() + function. The new function name is now + g_io_gnutls_load(gpointer data). See Android/iOS sections above for + further details. + + +Schedule for 1.18 + +Our next major feature release will be 1.18, and 1.17 will be the +unstable development version leading up to the stable 1.18 release. The +development of 1.17/1.18 will happen in the git master branch. + +The plan for the 1.18 development cycle is yet to be confirmed, but it +is expected that feature freeze will be around July 2019 followed by +several 1.17 pre-releases and the new 1.18 stable release in +August/September. + +1.18 will be backwards-compatible to the stable 1.16, 1.14, 1.12, 1.10, +1.8, 1.6, 1.4, 1.2 and 1.0 release series. + +------------------------------------------------------------------------ + +_These release notes have been prepared by Tim-Philipp Müller with_ +_contributions from Sebastian Dröge and Guillaume Desmottes._ + +_License: CC BY-SA 4.0_
