What this + commit introduces is a new allocator that allows us to track + the GstMemory objects independently. Now, when a buffer returns + to the pool, it is not necessary for the memory to be released + as well. We simply track the memory's ref count in the allocator + and we return the OMX buffer back when the memory's ref count + drops to 0. + The reason for doing this is to allow implementing zero-copy + transfers in situations where we may need to copy or map a + certain region of the buffer.

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 - -- line21encoder, line21decoder: inject/extract line21 closed captions - to/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, h264parse extracts Closed Captions from MPEG-2/H.264 - video streams - -- avviddec, avvidenc, x264enc got support for extracting/injecting - Closed Captions - -- 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. +- FIXME 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, - line21encoder, 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. +- FIXME 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 - -- srtpdec, srtpenc: add support for AES-GCM and also add support for - it in gst-rtsp-server and rtspsrc. - -- 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 and supports the - XDG-Shell protocol. - -- decklinkvideosink, decklinkvideosrc support selecting between - half/full duplex - -- The vulkan plugin gained support for macOS and iOS via MoltenVK in - addition to the existing support for X11 and Wayland - -- imagefreeze has a new num-buffers property to limit the number of - buffers that are produced and to send an EOS event afterwards - -- webrtcbin has a new, introspectable get-transceiver signal in - addition to the old get-transceivers signal that couldn’t be used - from bindings - -- Support for per-element latency information was added to the latency - tracer +- FIXME 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. +- FIXME 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. +- FIXME 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 - -- GstDiscoverer has support for caching the results of discovery in - the default cache directory. This can be enabled with the use-cache - property and is disabled by default. - -- GstMeta that are attached to GstBuffers are now always stored in the - order in which they were added. - -- Additional support for signalling ONVIF specific features were - added: the SEEK event can store a trickmode-interval now and support - for the Rate-Control and Frames RTSP headers was added to the RTSP - library. +- FIXME 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. +across all components and modules. Some of them 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 +- FIXME GstPlayer -- API was added to fine-tune the synchronisation offset between - subtitles and video +- FIXME 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! +- FIXME 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. - -- The OpenGL library no longer restores the OpenGL viewport. This is a - performance optimization to not require performing multiple - expensive glGet*() function calls per frame. This affects any - application or plugin use of the following functions and objects: - - glcolorconvert library object (not the element) - - glviewconvert library object (not the element) - - gst_gl_framebuffer_draw_to_texture() - - custom GstGLWindow implementations +- FIXME 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: - -- 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. +- FIXME 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. +- FIXME 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 +- FIXME GStreamer VAAPI -- Support Wayland’s display for context sharing, so the application - can pass its own wl_display in order to be used for the VAAPI - display creation. - -- A lot of work to support new Intel hardware using media-driver as VA - backend. - -- For non-x86 devices, VAAPI display can instantiate, through DRM, - with no PCI bus. This enables the usage of libva-v4l2-request - driver. - -- Added support for XDG-shell protocol as wl_shell replacement which - is currently deprecated. This change add as dependency - wayland-protocol. - -- GstVaapiFilter, GstVaapiWindow, and GstVaapiDecoder classes now - inherit from GstObject, gaining all the GStreamer’s instrumentation - support. - -- The metadata now specifies the plugin as Hardware class. - -- H264 decoder is more stable with problematic streams. - -- In H265 decoder added support for profiles main-422-10 (P010_10LE), - main-444 (AYUV) and main-444-10 (Y410) - -- JPEG decoder handles dynamic resolution changes. - -- More specification adherence in H264 and H265 encoders. +- FIXME 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. Video encoders will also - use this query to adjust their number of allocated buffers - preventing starvation when using dynamic buffer mode. - -- The OMX_PERFORMANCE debug category has been renamed to OMX_API_TRACE - and can now be used to track a widder variety of interactions - between OMX and GStreamer. - -- Video encoders will now detect frame rate only changes and will - inform OMX about it rather than doing a full format reset. - -- Various Zynq UltraScale+ specific improvements: - - Video encoders are now able to import dmabuf from upstream. - - Support for HEVC range extension profiles and more AVC profiles. - - We can now request video encoders to generate an IDR using the - force key unit event. +- FIXME GStreamer Editing Services and NLE -- Added a gesdemux element, it is an auto pluggable element that - allows decoding edit list like files supported by GES - -- Added gessrc which wraps a GESTimeline as a standard source element - (implementing the ges protocol handler) - -- Added basic support for videorate::rate property potentially - allowing changing playback speed - -- Layer priority is now fully automatic and they should be moved with - the new ges_timeline_move_layer method, ges_layer_set_priority is - now deprecated. - -- Added a ges_timeline_element_get_layer_priority so we can simply get - all information about GESTimelineElement position in the timeline - -- GESVideoSource now auto orientates the images if it is defined in a - meta (overridable). - -- Added some PyGObject overrides to make the API more pythonic - -- The threading model has been made more explicit with safe guard to - make sure not thread safe APIs are not used from the wrong threads. - It is also now possible to properly handle in what thread the API - should be used. - -- Optimized GESClip and GESTrackElement creation - -- Added a way to compile out the old, unused and deprecated - GESPitiviFormatter - -- Re implemented the timeline editing API making it faster and making - the code much more maintainable - -- Simplified usage of nlecomposition outside GES by removing quirks in - it API usage and removing the need to treat it specially from an - application perspective. - -- ges-launch-1.0: - - - Added support to add titles to the timeline - - Enhance the help auto generating it from the code - -- Deprecate ges_timeline_load_from_uri as loading the timeline should - be done through a project now - -- MANY leaks have been plugged and the unit testsuite is now “leak - free” +- FIXME GStreamer validate -- Added an action type to verify the checksum of the sink last-sample - -- Added an include keyword to validate scenarios - -- Added the notion of variable in scenarios, with the set-vars keyword - -- Started adding support for “performance” like tests by allowing to - define the number of dropped buffers or the minimum buffer frequency - on a specific pad - -- Added a validateflow plugin which allows defining the data flow to - be seen on a particular pad and verifying that following runs match - the expectations - -- Added support for appsrc based test definition so we can instrument - the data pushed into the pipeline from scenarios - -- Added a mockdecryptor allowing adding tests with on encrypted files, - the element will potentially be instrumented with a validate - scenario - -- gst-validate-launcher: - - - Cleaned up output - - - Changed the default for “muting” tests as user doesn’t expect - hundreds of windows to show up when running the testsuite - - - Fixed the outputted xunit files to be compatible with GitLab - - - Added support to run tests on media files in push mode (using - pushfile://) - - - Added support for running inside gst-build - - - Added support for running ssim tests on rendered files - - - Added a way to simply define tests on pipelines through a simple - .json file - - - Added a python app to easily run python testsuite reusing all - the launcher features - - - Added flatpak knowledge so we can print backtrace even when - running from within flatpak - - - Added a way to automatically generated “known issues” - suppressions lines - - - Added a way to rerun tests to check if they are flaky and added - a way to tolerate tests known to be flaky - - - Add a way to output html log files +- FIXME GStreamer Python Bindings -- add binding for gst_pad_set_caps() - -- pygobject dependency requirement was bumped to >= 3.8 - -- new audiotestsrc, audioplot, and mixer plugin examples, and a - dynamic pipeline example +- FIXME GStreamer C# Bindings -- bindings for the GstWebRTC library +- FIXME GStreamer Rust Bindings -The GStreamer Rust bindings are now officially part of the GStreamer -project and are also maintained in the GStreamer GitLab. - -The releases will generally not be synchronized with the releases of -other GStreamer parts due to dependencies on other projects. - -Also unlike the other GStreamer libraries, the bindings will not commit -to full API stability but instead will follow the approach that is -generally taken by Rust projects, e.g.: - -1) 0.12.X will be completely API compatible with all other 0.12.Y - versions. -2) 0.12.X+1 will contain bugfixes and compatible new feature additions. -3) 0.13.0 will _not_ be backwards compatible with 0.12.X but projects - will be able to stay at 0.12.X without any problems as long as they - don’t need newer features. - -The current stable release is 0.12.2 and the next release series will be -0.13, probably around March 2019. - -At this point the bindings cover most of GStreamer core (except for most -notably GstAllocator and GstMemory), and most parts of the app, audio, -base, check, editing-services, gl, net. pbutils, player, rtsp, -rtsp-server, sdp, video and webrtc libraries. - -Also included is support for creating subclasses of the following types -and writing GStreamer plugins: - -- gst::Element -- gst::Bin and gst::Pipeline -- gst::URIHandler and gst::ChildProxy -- gst::Pad, gst::GhostPad -- gst_base::Aggregator and gst_base::AggregatorPad -- gst_base::BaseSrc and gst_base::BaseSink -- gst_base::BaseTransform - -Changes to 0.12.X since 0.12.0 - -Fixed - -- PTP clock constructor actually creates a PTP instead of NTP clock - -Added - -- Bindings for GStreamer Editing Services -- Bindings for GStreamer Check testing library -- Bindings for the encoding profile API (encodebin) - -- VideoFrame, VideoInfo, AudioInfo, StructureRef implements Send and - Sync now -- VideoFrame has a function to get the raw FFI pointer -- From impls from the Error/Success enums to the combined enums like - FlowReturn -- Bin-to-dot file functions were added to the Bin trait -- gst_base::Adapter implements SendUnique now -- More complete bindings for the gst_video::VideoOverlay interface, - especially - gst_video::is_video_overlay_prepare_window_handle_message() - -Changed - -- All references were updated from GitHub to freedesktop.org GitLab -- Fix various links in the README.md -- Link to the correct location for the documentation -- Remove GitLab badge as that only works with gitlab.com currently - -Changes in git master for 0.13 - -Fixed - -- gst::tag::Album is the album tag now instead of artist sortname - -Added - -- Subclassing infrastructure was moved directly into the bindings, - making the gst-plugin crate deprecated. This involves many API - changes but generally cleans up code and makes it more flexible. - Take a look at the gst-plugins-rs crate for various examples. - -- Bindings for CapsFeatures and Meta -- Bindings for - ParentBufferMeta,VideoMetaandVideoOverlayCompositionMeta` -- Bindings for VideoOverlayComposition and VideoOverlayRectangle -- Bindings for VideoTimeCode - -- UniqueFlowCombiner and UniqueAdapter wrappers that make use of the - Rust compile-time mutability checks and expose more API in a safe - way, and as a side-effect implement Sync and Send now - -- More complete bindings for Allocation Query -- pbutils functions for codec descriptions -- TagList::iter() for iterating over all tags while getting a single - value per tag. The old ::iter_tag_list() function was renamed to - ::iter_generic() and still provides access to each value for a tag -- Bus::iter() and Bus::iter_timed() iterators around the corresponding - ::pop\*() functions - -- serde serialization of Value can also handle Buffer now - -- Extensive comments to all examples with explanations -- Transmuxing example showing how to use typefind, multiqueue and - dynamic pads -- basic-tutorial-12 was ported and added - -Changed - -- Rust 1.31 is the minimum supported Rust version now -- Update to latest gir code generator and glib bindings - -- Functions returning e.g. gst::FlowReturn or other “combined” enums - were changed to return split enums like - Result<gst::FlowSuccess, gst::FlowError> to allow usage of the - standard Rust error handling. - -- MiniObject subclasses are now newtype wrappers around the underlying - GstRc<FooRef> wrapper. This does not change the API in any breaking - way for the current usages, but allows MiniObjects to also be - implemented in other crates and makes sure rustdoc places the - documentation in the right places. - -- BinExt extension trait was renamed to GstBinExt to prevent conflicts - with gtk::Bin if both are imported - -- Buffer::from_slice() can’t possible return None - -- Various clippy warnings +- FIXME GStreamer Rust Plugins -Like the GStreamer Rust bindings, the Rust plugins are now officially -part of the GStreamer project and are also maintained in the GStreamer -GitLab. - -In the 0.3.x versions this contained infrastructure for writing -GStreamer plugins in Rust, and a set of plugins. - -In git master that infrastructure was moved to the GLib and GStreamer -bindings directly, together with many other improvements that were made -possible by this, so the gst-plugins-rs repository only contains -GStreamer elements now. - -Elements included are: - -- Tutorials plugin: identity, rgb2gray and sinesrc with extensive - comments - -- rsaudioecho, a port of the audiofx element - -- rsfilesrc, rsfilesink - -- rsflvdemux, a FLV demuxer.
