Hardware codecs for AV1 are slowly - becoming available in embedded systems and desktop GPUs (AMD, Intel, - NVIDIA), and these can now be used via GStreamer. - -- New AV1 RTP payloader and depayloader elements. - -- New encoder settings in the AOM reference encoder-based av1enc - element. - -- Various improvements in the AV1 parser and in the MP4/Matroska/WebM - muxers/demuxers. - -- dav1d and rav1e based software decoder/encoder elements shipped as - part of the binaries. - -- AV1 parser improvements and various bugfixes all over the place. - -Touchscreen event support in Navigation API - -The Navigation API supports the sending of key press events and mouse -events through a GStreamer pipeline. Typically these will be picked up -by a video sink on which these events happen and then the event is -transmitted into the pipeline so it can be handled by elements inside -the pipeline if it wasn’t handled by the application. - -This has traditionally been used for DVD menu support, but can also be -used to forward such inputs to source elements that render a web page -using a browser engine such as WebKit or Chromium. - -This API has now gained support for touchscreen events, and this has -been implemented in various plugins such as the GTK, Qt, XV, and x11 -video sinks as well as the wpevideosrc element. - -GStreamer CUDA integration - -- New gst-cuda library -- integration with D3D11 and NVIDIA dGPU NVMM elements -- new cudaconvertscale element - -GStreamer Direct3D11 integration - -- New gst-d3d11 public library - - gst-d3d11 library is not integrated with GStreamer documentation - system yet. Please refer to the examples -- d3d11screencapture: Add Windows Graphics Capture API based capture - mode, including Win32 application window capturing -- d3d11videosink and d3d11convert can support flip/rotation and crop - meta -- d3d11videosink: New emit-present property and present signal so that - applications can overlay an image on Direct3D11 swapchain’s - backbuffer via Direct3D/Direct2D APIs. See also C++ and Rust - examples -- d3d11compositor supports YUV blending/composing without intermediate - RGB(A) conversion to improve performance -- Direct3D11 video decoders are promoted to GST_RANK_PRIMARY or - higher, except for the MPEG2 decoder - -H.264/H.265 timestamp correction elements - -- Muxers are often picky and need proper PTS/DTS timestamps set on the - input buffers, but that can be a problem if the encoded input media - stream comes from a source that doesn’t provide proper signalling of - DTS, such as is often the case for RTP, RTSP and WebRTC streams or - Matroska container files. Theoretically parsers should be able to - fix this up, but it would probably require fairly invasive changes - in the parsers, so two new elements h264timestamper and - h265timestamper bridge the gap in the meantime and can reconstruct - missing PTS/DTS. - -Easy sender timestamp reconstruction for RTP and RTSP - -- it was always possible to reconstruct and retrieve the original RTP - sender timestamps in GStreamer, but required a fair bit of - understanding of the internal mechanisms and the right property - configuration and clock setup. - -- rtspsrc and rtpjitterbuffer gained a new - “add-reference-timestamp-meta” property that if set puts the - original absolute reconstructed sender timestamps on the output - buffers via a meta. This is particularly useful if the sender is - synced to an NTP clock or PTP clock. The original sender timestamps - are either based on the RTCP NTP times, NTP RTP header extensions - (RFC6051) or RFC7273-style clock signalling. - -Qt6 support - -- new qml6glsink element for Qt6 similar to the existing Qt5 element. - Matching source and overlay elements will hopefully follow in the - near future. - -OpenGL + Video library enhancements - -- Support for new video formats (NV12_4L4, NV12_16L32S, NV12_8L128, - NV12_10BE_8L128) and dmabuf import in more formats (Y410, Y212_LE, - Y212_BE, Y210, NV21, NV61) - -- Improved support for tiled formats with arbitrary tile dimensions, - as needed by certain hardware decoders/encoders - -- glvideomixer: New “crop-left,”crop-right, “crop-top” and - “crop-bottom” pad properties for cropping inputs - -- OpenGL support for gst_video_sample_convert(): - - - Used for video snapshotting and thumbnailing, to convert buffers - retrieved from appsinks or sink “last-sample” properties in - JPG/PNG thumbnails. - - This function can now take samples and buffers backed by GL - textures as input and will automatically plug a gldownload - element in that case. - -High bit-depth support (10, 12, 16 bits per component value) improvements - -- compositor can now handle any supported input format and also mix - high-bitdepth (10-16 bit) formats (naively) - -- videoflip has gained support for higher bit depth formats. - -- vp9enc, vp9dec now support 12-bit formats and also 10-bit 4:4:4 - -WebRTC - -- Allow insertion of bandwidth estimation elements e.g. for Google - Congestion Control (GCC) support - -- Initial support for sending or receiving simulcast streams - -- Support for asynchronous host resolution for STUN/TURN servers - -- GstWebRTCICE was split into base classes and implementation to make - it possible to plug custom ICE implementations - -- webrtcsink: batteries-included WebRTC sender (Rust) - -- whipsink: WebRTC HTTP ingest (WHIP) to a MediaServer (Rust) - -- whepsrc: WebRTC HTTP egress (WHEP) from a MediaServer (Rust) - -- Many other improvements and bug fixes - -New HLS, DASH and MSS adaptive streaming clients - -A new set of “adaptive demuxers” to support HLS, DASH and MSS adaptive -streaming protocols has been added. They provide improved performance, -new features and better stream compatibility compared to the previous -elements. These new elements require a “streams-aware” pipeline such as -playbin3, uridecodebin3 or urisourcebin. - -The previous elements’ design prevented implementing several use-cases -and fixing long-standing issues. The new elements were re-designed from -scratch to tackle those: - -- Scheduling Only 3 threads are present, regardless of the number of - streams selected. One in charge of downloading fragments and - manifests, one in charge of outputting parsed data downstream, and - one in charge of scheduling. This improves performance, resource - usage and latency. - -- Better download control The elements now directly control the - scheduling and download of manifests and fragments using libsoup - directly instead of depending on external elements for downloading. - -- Stream selection, only the selected streams are downloaded. This - improves bandwith usage. Switching stream is done in such a way to - ensure there are no gaps, meaning the new stream will be switched to - only once enough data for it has been downloaded. - -- Internal parsing, the downloaded streams are parsed internally. This - allows the element to fully respect the various specifications and - offer accurate buffering, seeking and playback. This is especially - important for HLS streams which require parsing for proper - positioning of streams. - -- Buffering and adaptive rate switching, the new elements handle - buffering internally which allows them to have a more accurate - visibility of which bandwith variant to switch to. - -Playbin3, Decodebin3, UriDecodebin3, Parsebin improvements - -The “new” playback elements introduced in 1.18 (playbin3 and its various -components) have been refactored to allow more use-cases and improve -performance. They are no longer considered experimental, so applications -using the legacy playback elements (playbin and (uri)decodebin) can -migrate to the new components to benefit from these improvements. - -- Gapless The “gapless” feature allows files and streams to be - fetched, buffered and decoded in order to provide a “gapless” - output. This feature has been refactored extensively in the new - components: - - A single (uri)decodebin3 (and therefore a single set of - decoders) is used. This improves memory and cpu usage, since on - identical codecs a single decoder will be used. - - The “next” stream to play will be pre-rolled “just-in-time” - thanks to the buffering improvements in urisourcebin (see below) - - This feature is now handled at the uridecodebin3 level. - Applications that wish to have a “gapless” stream and process it - (instead of just outputting it, for example for transcoding, - retransmission, …) can now use uridecodebin3 directly. Note that - a streamsynchronizer element is required in that case. -- Buffering improvements The urisourcebin element is in charge of - fetching and (optionally) buffering/downloading the stream. It has - been extended and improved: - - When the parse-streams property is used (by default in - uridecodebin3 and playbin3), compatible streams will be demuxed - and parsed (via parsebin) and buffering will be done on the - elementary streams. This provides a more accurate handling of - buffering. Previously buffering was done on a best-effort basis - and was mostly wrong (i.e. downloading more than needed). - - Applications can use urisourcebin with this property as a - convenient way of getting elementary streams from a given URI. - - Elements can handle buffering themselves (such as the new - adaptive demuxers) by answering the GST_QUERY_BUFFERING query. - In that case urisourcebin will not handle it. -- Stream Selection Efficient stream selection was previously only - possible within decodebin3. The downside is that this meant that - upstream elements had to provide all the streams from which to chose - from, which is inefficient. With the addition of the - GST_QUERY_SELECTABLE query, this can now be handled by elements - upstream (i.e. sources) - - Elements that can handle stream selection internally (such as - the new adaptive demuxer elements) answer that query, and handle - the stream selection events themselves. - - In this case, decodebin3 will always process all streams that - are provided to it. -- Instant URI switching This new feature allows switching URIs - “instantly” in playbin3 (and uridecodebin3) without having to change - states. This mimics switching channels on a television. - - If compatible, decoders will be re-used, providing lower - latency/cpu/memory than by switching states. - - This is enabled by setting the instant-uri property to true, - setting the URI to switch to immediately, and then disabling the - instant-uri property again afterwards. -- playbin3, decodebin3, uridecodebin3, parsebin, and urisrc are no - longer experimental - - They were originally marked as ‘technology preview’ but have - since seen extensive usage in production settings, so are - considered ready for general use now. - -Fraunhofer AAC audio encoder HE-AAC and AAC-LD profile support - -- fdkaacenc: - - Support for encoding to HE-AACv1 and HE-AACv2 profile - - Support for encoding to AAC Low Delay (LD) profile - - Advanced bitrate control options via new “rate-control”, - “vbr-preset”, “peak-bitrate”, and “afterburner” properties - -RTP rapid synchronization support in the RTP stack (RFC6051) - -RTP provides several mechanisms how streams can be synchronized relative -to each other, and how absolute sender times for RTP packets can be -obtained. One of these mechanisms is via RTCP, which has the -disadvantage that the synchronization information is only distributed -out-of-band and usually some time after the start. - -GStreamer’s RTP stack, specifically the rtpbin, rtpsession and -rtpjitterbuffer elements, now also have support for retrieving and -sending the same synchronization information in-band via RTP header -extensions according to RFC6051 (Rapid Synchronisation of RTP Flows). -Only 64-bit timestamps are supported currently. - -This provides per packet synchronization information from the very -beginning of a stream and allows accurate inter-stream, and (depending -on setup) inter-device, synchronization at the receiver side. - -ONVIF XML Timed Metadata support - -The ONVIF standard implemented by various security cameras also -specifies a format for timed metadata that is transmitted together with -the audio/video streams, usually over RTSP. - -Support for this timed metadata is implemented in the MP4 demuxer now as -well as the new fragmented MP4 muxer and the new non-fragmented MP4 -muxer from the GStreamer Rust plugins. Additionally, the new onvif -plugin ‒ which is part of the GStreamer Rust plugins ‒ provides general -elements for handling the metadata and e.g. overlaying certain parts of -it over a video stream. - -As part of this support for absolute UTC times was also implemented -according to the requirements of the ONVIF standards in the -corresponding elements. - -MP3 gapless playback support - -While MP3 can probably considered a legacy format at this point, a new -feature was added with this release. - -When playing back plain MP3 files, i.e. outside a container format, -switches between files can now be completely gapless if the required -metadata is provided inside the file. There is no standardized metadata -for this, but the LAME MP3 encoder writes metadata that can be parsed by -the mpegaudioparse element now and forwarded to decoders for ensuring -removal of padding samples at the front and end of MP3 files. - -“force-live” property for audio + video aggregators - -This is a quality of life fix for playout and streaming applications -where it is common to have audio and video mixer elements that should -operate in live mode from the start and produce output continuously. - -Often one would start a pipeline without any inputs hooked up to these -mixers in the beginning, and up until now there was no way to easily -force these elements into live mode from the start. One would have to -add an initial live video or audio test source as dummy input to achieve -this. - -The new “force-live” property makes these audio and video aggregators -start in live mode without the need for any dummy inputs, which is -useful for scenarios where inputs are only added after starting the -pipeline. - -This new property should usually be used in connection with the -“min-upstream-latency” property, i.e. you should always set a non-0 -minimum upstream latency then. - -This is now supported in all GstAudioAggregator and GstVideoAggregator -subclasses such as audiomixer, audiointerleave, compositor, -glvideomixer, d3d11compositor, etc. +- This section will be completed in due course New elements and plugins -- new cudaconvertscale element that can convert and scale in one pass - -- new gtkwaylandsink element based on gtksink, but similar to - waylandsink and uses Wayland APIs directly instead of rendering with - Gtk/Cairo primitives. This approach is only compatible with Gtk3, - and like gtksink this element only supports Gtk3. - -- new h264timestamper and h265timestamper elements to reconstruct - missing pts/dts from inputs that might not provide them such as - e.g. RTP/RTSP/WebRTC inputs (see above) - -- mfaacdec, mfmp3dec: Windows MediaFoundation AAC and MP3 decoders - -- new msdkav1enc AV1 video encoder element - -- new nvcudah264enc, nvcudah265enc, nvd3d11h264enc, and nvd3d11h265enc - NVIDIA GPU encoder elements to support zero-copy encoding, via CUDA - and Direct3D11 APIs, respectively - -- new nvautogpuh264enc and nvautogpuh265enc NVIDIA GPU encoder - elements: The auto GPU elements will automatically select a target - GPU instance in case multiple NVIDIA desktop GPUs are present, also - taking into account the input memory. On Windows CUDA or Direct3D11 - mode will be determined by the elements automatically as well. Those - new elements are useful if target GPU and/or API mode (either CUDA - or Direct3D11 in case of Windows) is undeterminable from the encoder - point of view at the time when pipeline is configured, and therefore - lazy target GPU and/or API selection are required in order to avoid - unnecessary memory copy operations. - -- new nvav1dec AV1 NVIDIA desktop GPU decoder element - -- new qml6glsink element to render video with Qt6 - -- qsv: New Intel OneVPL/MediaSDK (a.k.a Intel Quick Sync) based - decoder and encoder elements, with gst-d3d11 (on Windows) and gst-va - (on Linux) integration - - - Support multi-GPU environment, for example, concurrent video - encoding using Intel iGPU and dGPU in a single pipeline - - H.264 / H.265 / VP9 and JPEG decoders - - H.264 / H.265 / VP9 / AV1 / JPEG encoders with dynamic encoding - bitrate update - - New plugin does not require external SDK for building on Windows - -- vulkanoverlaycompositor: new vulkan overlay compositor element to - overlay upstream GstVideoOverlayCompositonMeta onto the video - stream. - -- vulkanshaderspv: performs operations with SPIRV shaders in Vulkan - -- win32ipcvideosink, win32ipcvideosrc: new shared memory videosrc/sink - elements for Windows - -- wicjpegdec, wicpngdec: Windows Imaging Component (WIC) based JPEG - and PNG decoder elements. - -- Many exciting new Rust elements, see Rust section below +- This section will be completed in due course New element features and additions -- audioconvert: Dithering now uses a slightly slower, less biased PRNG - which results in better quality output. Also dithering can now be - enabled via the new “dithering-threshold” property for target bit - depths of more than 20 bits. - -- av1enc: Add “keyframe-max-dist” property for controlling max - distance between keyframes, as well as “enc-pass”, “keyframe-mode”, - “lag-in-frames” and “usage-profile” properties. - -- cccombiner: new “output-padding” property - -- decklink: Add support for 4k DCI, 8k/UHD2 and 8k DCI modes - -- dvbsubenc: Support for >SD resolutions is working correctly now. - -- fdkaacenc: Add HE-AAC / HE-AACv2 profile support - -- glvideomixer: New “crop-left,”crop-right, “crop-top” and - “crop-bottom” pad properties for cropping inputs - -- gssink: new ‘content-type’ property. Useful when one wants to upload - a video as video/mp4 instead of ’video/quicktime` for example. - -- jpegparse: Rewritten using the common parser library - -- msdk: - - - new msdkav1enc AV1 video encoder element - - msdk decoders: Add support for Scaler Format Converter (SFC) on - supported Intel platforms for hardware accelerated conversion - and scaling - - msdk encoders: support import of dmabuf, va memory and D3D11 - memory - - msdk encoders: add properties for low delay bitrate control and - max frame sizes for I/P frames - - msdkh264enc, msdkh265enc: more properties to control intra - refresh - - note that on systems with multi GPUs the Windows D3D11 - integration might only work reliably if the Intel GPU is the - primary GPU - -- mxfdemux: Add support for Canon XF-HEVC - -- openaptx: Support the freeaptx library - -- qroverlay: - - - new “qrcode-case-sensitive” property allows encoding case - sensitive strings like wifi SSIDs or passwords. - - added the ability to pick up data to render from an - upstream-provided custom GstQROverlay meta - -- qtdemux: Add support for ONVIF XML Timed MetaData and AVC-Intra - video - -- rfbsrc now supports the uri handler interface, so applications can - use RFB/VNC sources in uridecodebin(3) and playbin, with - e.g. rfb://:password@10.1.2.3:5903?shared=1 - -- rtponviftimestamp: Add support for using reference timestamps - -- rtpvp9depay now has the same keyframe-related properties as - rtpvp8depay and rtph264depay: “request-keyframe” and - “wait-for-keyframe” - -- rtspsrc: Various RTSP servers are using invalid URL operations for - constructing the control URL. Until GStreamer 1.16 these worked - correctly because GStreamer was just appending strings itself to - construct the control URL, but starting version 1.18 the correct URL - operations were used. With GStreamer 1.22, rtspsrc now first tries - with the correct control URL and if that fails it will retry with - the wrongly constructed control URL to restore support for such - servers. - -- rtspsrc and rtpjitterbuffer gained a new - “add-reference-timestamp-meta” property that makes them put the - unmodified original sender timestamp on output buffers for NTP or - PTP clock synced senders - -- srtsrc, srtsink: new “auto-reconnect” property to make it possible - to disable automatic reconnects (in caller mode) and make the - elements post an error immediately instead; also stats improvements - -- srtsrc: new “keep-listening” property to avoid EOS on disconnect and - keep the source running while it waits for a new connection. - -- videocodectestsink: added YUV 4:2:2 support - -- wasapi2src: Add support for process loopback capture - -- wpesrc: Add support for modifiers in key/touch/pointer events +- This section will be completed in due course Plugin and library moves -- The xingmux plugin has been moved from gst-plugins-ugly into - gst-plugins-good. - -- The various Windows directshow plugins in gst-plugins-bad have been - unified into a single directshow plugin. +- This section will be completed in due course Plugin removals -- The dxgiscreencapsrc element has been removed, use - d3d11screencapturesrc instead +- This section will be completed in due course Miscellaneous API additions -- GST_AUDIO_FORMAT_INFO_IS_VALID_RAW() and - GST_VIDEO_FORMAT_INFO_IS_VALID_RAW() can be used to check if a - GstAudioFormatInfo or GstVideoFormatInfo has been initialised to a - valid raw format. - -- Video SEI meta: new GstVideoSEIUserDataUnregisteredMeta to carry - H.264 and H.265 metadata from SEI User Data Unregistered messages. - -- vulkan: Expose gst_vulkan_result_to_string() +- This section will be completed in due course Miscellaneous performance, latency and memory optimisations -- liborc 0.4.33 adds support for aarch64 (64-bit ARM) architecture - (not enabled by default on Windows yet though) and improvements for - 32-bit ARM and should greatly enhance performance for certain - operations that use ORC. +- This section will be completed in due course -- as always there have been plenty of performance, latency and memory - optimisations all over the place. +- liborc 0.4.35 (latest: 0.4.36) adds support for AVX/AVX2 and contains improvements for the SSE backend. -Miscellaneous other changes and enhancements +- as always there have been plenty of performance, latency and memory optimisations all over the place. -- the audio/video decoder base classes will not consider decoding - errors a hard error by default anymore but will continue trying to - decode. Previously more than 10 consecutive errors were considered a - hard error but this caused various partially broken streams to fail. - The threshold is configurable via the “max-errors” property. +Miscellaneous other changes and enhancements -- compatibility of the GStreamer PTP clock implementation with - different PTP server implementations was improved, and - synchronization is achieved successfully in various scenarios that - failed before. +- This section will be completed in due course Tracing framework and debugging improvements New tracers -- buffer-lateness: Records lateness of buffers and the reported - latency for each pad in a CSV file. Comes with a script for - visualisation. - -- pipeline-snapshot: Creates a .dot file of all pipelines in the - application whenever requested via SIGUSR1 (on UNIX systems) - -- queue-levels: Records queue levels for each queue in a CSV file. - Comes with a script for visualisation. +- This section will be completed in due course Debug logging system improvements -- new log macros GST_LOG_ID, GST_DEBUG_ID, GST_INFO_ID, - GST_WARNING_ID, GST_ERROR_ID, and GST_TRACE_ID allow passing a - string identifier instead of a GObject. This makes it easier to log - non-gobject-based items and also has performance benefits. +- This section will be completed in due course Tools -- gst-play-1.0 gained a --no-position command line option to suppress - position/duration queries, which can be useful to reduce debug log - noise. +- This section will be completed in due course GStreamer FFMPEG wrapper -- Fixed bitrate management and timestamp inaccuracies for video - encoders - -- Fix synchronization issues and errors created by the (wrong) - forwarding of upstream segment events by ffmpeg demuxers. - -- Clipping meta support for gapless mp3 playback +- This section will be completed in due course GStreamer RTSP server -- Add RFC5576 Source-specific media attribute to the SDP media for - signalling the CNAME - -- Add support for adjusting request response on pipeline errors - - - Give the application the possibility to adjust the error code - when responding to a request. For that purpose the pipeline’s - bus messages are emitted to subscribers through a - “handle-message” signal. The subscribers can then check those - messages for errors and adjust the response error code by - overriding the virtual method - GstRTSPClientClass::adjust_error_code(). - -- Add gst_rtsp_context_set_token() method to make it possible to set - the RTSPToken on some RTSPContext from bindings such as the Python - bindings. - -- rtspclientsink gained a “publish-clock-mode” property to configure - whether the pipeline clock should be published according to RFC7273 - (RTP Clock Source Signalling), similar to the same API on - GstRTSPMedia. +- This section will be completed in due course GStreamer VA-API support -- Development activity has shifted towards the new va plugin, with - gstreamer-vaapi now basically in maintenance-only mode.

The OpenMAX standard is long dead and even the Raspberry Pi OS no longer supports it. + There has not been any development since 1.22 was released. Users of these elements should switch to the Video4Linux-based + video encoders and decoders which have been the standard on embedded Linux for quite some time now. GStreamer Editing Services and NLE -- Handle compositors that are bins around the actual compositor - implementation (like glvideomixers which wraps several elements) - -- Add a mode to disable timeline editing API so the user can be in - full control of its layout (meaning that the user is responsible for - ensuring its validity/coherency) - -- Add a new fade-in transition type - -- Add support for non-1/1 PAR source videos - -- Fix frame accuracy when working with very low framerate streams +- This section will be completed in due course GStreamer validate -- Clean up and stabilize API so we can now generate rust bindings - -- Enhance the appsrc-push action type allowing to find tune the - buffers more in details - -- Add an action type to verify currently configured pad caps - -- Add a way to run checks from any thread after executing a ‘wait’ - action.

See below for the list of shipped plugins and the - status of Rust support in cerbero. +The GStreamer Rust bindings are released separately with a different release cadence that’s tied to gtk-rs, but the latest +release has already been updated for the new GStreamer 1.24 API. -- The Rust plugins are also part of the documentation on the GStreamer - website now. +gst-plugins-rs, the module containing GStreamer plugins written in Rust, has also seen lots of activity with many new elements +and plugins -- Rust plugins can be used from any programming language. To the - outside they look just like a plugin written in C or C++. +- Rust plugins can be used from any programming language. To the outside they look just like a plugin written in C or C++. New Rust plugins and elements -- rtpav1pay / rtpav1depay: RTP (de)payloader for the AV1 video codec -- gtk4paintablesink: a GTK4 video sink that provides a GdkPaintable - for rendering a video in any place inside a GTK UI. Supports - zero-copy rendering via OpenGL on Linux and macOS. -- ndi: source, sink and device provider for NewTek NDI protocol -- onvif: Various elements for parsing, RTP (de)payloading, overlaying - of ONVIF timed metadata. -- livesync: Element for converting a live stream into a continuous - stream without gaps and timestamp jumps while preserving live - latency requirements. -- raptorq: Encoder/decoder elements for the RaptorQ FEC mechanism that - can be used for RTP streams (RFC6330). - -WebRTC elements - -- webrtcsink: a WebRTC sink (batteries included WebRTC sender with - specific signalling) -- whipsink: WebRTC HTTP ingest (WHIP) to MediaServer -- whepsrc: WebRTC HTTP egress (WHEP) from MediaServer -- rtpgccbwe: RTP bandwidth estimator based on the Google Congestion - Control algorithm (GCC), used by webrtcsink - -Amazon AWS services - -- awss3src / awss3sink: A source and sink element to talk to the - Amazon S3 object storage system. -- awss3hlssink: A sink element to store HLS streams on Amazon S3. -- awstranscriber: an element wrapping the AWS Transcriber service. -- awstranscribeparse: an element parsing the packets of the AWS - Transcriber service. - -Video Effects (videofx) - -- roundedcorners: Element to make the corners of a video rounded via - the alpha channel. -- colordetect: A pass-through filter able to detect the dominant - color(s) on incoming frames, using color-thief. -- videocompare: Compare similarity of video frames. The element can - use different hashing algorithms like Blockhash, DSSIM, and others. - -New MP4 muxer + Fragmented MP4 muxer - -- fmp4mux: New fragmented MP4/ISOBMFF/CMAF muxer for generating - e.g. DASH/HLS media fragments. -- isomp4mux: New non-fragmented, normal MP4 muxer. - -Both plugins provides elements that replace the existing qtmux/mp4mux -element from gst-plugins-good. While not feature-equivalent yet, the new -codebase and using separate elements for the fragment and non-fragmented -case allows for easier extensability in the future. +- This section will be completed in due course Cerbero Rust support -- Starting this release, cerbero has support for building and shipping - Rust code on Linux, Windows (MSVC) and macOS. The Windows (MSVC) and - macOS binaries also ship the GStreamer Rust plugins in this release. - Only dynamic plugins are built and shipped currently. - -- Preliminary support for Android, iOS and Windows (MinGW) exists but - more work is needed. Check the tracker issue for more details about - future work. - -- The following plugins are included currently: audiofx, aws, cdg, - claxon, closedcaption, dav1d, fallbackswitch, ffv1, fmp4, gif, - hlssink3, hsv, json, livesync, lewton, mp4, ndi, onvif, rav1e, - regex, reqwest, raptorq, png, rtp, textahead, textwrap, threadshare, - togglerecord, tracers, uriplaylistbin, videofx, webrtc, webrtchttp. +- This section will be completed in due course Build and Dependencies -- meson 0.62 or newer is required - -- GLib >= 2.62 is now required (but GLib >= 2.64 is strongly - recommended) - -- libnice >= 0.1.21 is now required and contains important fixes for - GStreamer’s WebRTC stack. - -- liborc >= 0.4.33 is recommended for 64-bit ARM support and 32-bit - ARM improvements - -- onnx: OnnxRT >= 1.13.1 is now required - -- openaptx: can now be built against libfreeaptx - -- opencv: allow building against any 4.x version - -- shout: libshout >= 2.4.3 is now required - -- gstreamer-vaapi’s Meson build options have been switched from a - custom combo type (yes/no/auto) to the built-in Meson feature type - (enabled/disabled/auto) +- This section will be completed in due course -- The GStreamer Rust plugins module gst-plugins-rs is now considered - an essential part of the GStreamer plugin offering and packagers and - distributors are strongly encouraged to package and ship those - plugins alongside the existing plugin modules. +Monorepo build (neé gst-build) -- we now make use of Meson’s install tags feature which allows - selective installation of installl components and might be useful - for packagers. - -Monorepo build (gst-build) - -- new “orc-source” build option to allow build against a - system-installed liborc instead of forcing the use of orc as a - subproject. - -- GStreamer command line tools can now be linked to the gstreamer-full - library if it’s built +- This section will be completed in due course 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 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. General improvements -- Rust support was added for all support configurations, controlled by - the rust variant; see above for more details -- All pkgconfig files are now reliably relocatable without requiring - pkg-config --define-prefix. This also fixes statically linking with - GStreamer plugins using the corresponding pkgconfig files. -- New documentation on how to build a custom GStreamer repository - using Cerbero, please see the README -- HTTPS certificate checking is enabled for downloads on all platforms - now -- Fetching now automatically retries on error for robustness against - transient errors -- Support for building the new Qt6 plugin was added -- pkgconfig files for various recipes were fixed -- Several recipes were updated to newer versions -- New plugins: adaptivedemux2 aes codectimestamper dav1d -- New libraries: cuda webrtcnice +- This section will be completed in due course macOS / iOS -- Added support for running Cerbero on ARM64 macOS -- GStreamer.framework and all libraries in it are now relocatable, - which means they use LC_RPATH entries to find dependencies instead - of using an absolute path. If you link to GStreamer using the - pkgconfig files, no action is necessary. However, if you use the - framework directly or link to the libraries inside the framework by - hand, then you need to pass -Wl,-rpath,<path_to_libdir> to the - linker. -- Apple bitcode support was dropped, since Apple has deprecated it -- macOS installer now correctly advertises support for both x86_64 and - arm64 -- macOS framework now ships the gst-rtsp-server-1.0 library -- Various fixes were made to make static linking to gstreamer - libraries and plugins work correctly on macOS -- When statically linking to the applemedia plugin using Xcode 13, you - will need to pass -fno-objc-msgsend-selector-stubs which works - around a backwards-incompatible change in Xcode 14. This is not - required for the rest of GStreamer at present, but will be in the - future. -- macOS installer now shows the GStreamer logo correctly +- This section will be completed in due course Windows -- MSVC is now required by default on Windows, and the Visual Studio - variant is enabled by default - - To build with MinGW, use the mingw variant -- Visual Studio props files were updated for newer Visual Studio - versions -- Visual Studio 2015 support was dropped -- MSYS2 is now supported as the base instead of MSYS. Please see the - README for more details. Some advantages include: - - Faster build times, since parallel make works - - Faster bootstrap, since some tools are provided by MSYS2 - - Other speed-ups due to using MSYS2 tools instead of MSYS -- Faster download by using powershell instead of hand-rolled Python - code -- Many recipes were ported from Autotools to Meson, speeding up the - build -- Universal Windows Platform is no longer supported, and binaries are - no longer shipped for it -- New documentation on how to force a specific Visual Studio - installation in Cerbero, please see the README -- New plugins: qsv wavpack directshow amfcodec wic win32ipc -- New libraries: d3d11 - -Windows MSI installer - -- Universal Windows Platform prebuilt binaries are no longer available +- This section will be completed in due course Linux -- Various fixes for RHEL/CentOS 7 support -- Added support for running on Linux ARM64 +- This section will be completed in due course Android -- Android support now requires Android API version 21 (Lollipop) -- Support for Android Gradle plugin 7.2 +- This section will be completed in due course Platform-specific changes and improvements Android -- Android SDK 21 is required now as minimum SDK version - -- androidmedia: Add H.265 / HEVC video encoder mapping - -- Implement JNI_OnLoad() to register static plugins etc. automatically - in case GStreamer is loaded from Java using System.loadLibrary(), - which is also useful for the gst-full deployment scenario. +- This section will be completed in due course Apple macOS and iOS -- The GLib version shipped with the GStreamer binaries does not - initialize an NSApp and does not run a NSRunLoop on the main thread - anymore. This was a custom GLib patch and caused it to behave - different from the GLib shipped by Homebrew or anybody else. - - The change was originally introduced because various macOS APIs - require a NSRunLoop to run on the main thread to function correctly - but as this change will never get merged into GLib and it was - reverted for 1.22. Applications that relied on this behaviour should - move to the new gst_macos_main() function, which also does not - require the usage of a GMainLoop. - - See e.g. gst-play.c for an example for the usage of - gst_macos_main(). - -- GStreamer.framework and all libraries in it are now relocatable, - which means they use LC_RPATH entries to find dependencies instead - of using an absolute path. If you link to GStreamer using the - pkgconfig files, no action is necessary. However, if you use the - framework directly or link to the libraries inside the framework by - hand, then you need to pass -Wl,-rpath,<path_to_libdir> to the - linker. - -- avfvideosrc: Allow specifying crop coordinates during screen capture - -- vtenc, vtdec: H.265 / HEVC video encoding + decoding support - -- osxaudiosrc: Support a device as both input and output - - - osxaudiodeviceprovider now probes devices more than once to - determine if the device can function as both an input AND and - output device. Previously, if the device provider detected that - a device had any output capabilities, it was treated solely as - an Audio/Sink. This caused issues for devices that have both - input and output capabilities (for example, USB interfaces for - professional audio have both input and output channels). Such - devicesare now listed as both an Audio/Sink as well as an - Audio/Source. - -- osxaudio: support hidden devices on macOS - - - These are devices that will not be shown in the macOS UIs and - that cannot be retrieved without having the specific UID of the - hidden device. There are cases when you might want to have a - hidden device, for example when having a virtual speaker that - forwards the data to a virtual hidden input device from which - you can then grab the audio. The blackhole project supports - these hidden devices and this change provides a way that if the - device id is a hidden device it will use it instead of checkinf - the hardware list of devices to understand if the device is - valid. +- This section will be completed in due course Windows -- win32ipcvideosink, win32ipcvideosrc: new shared memory videosrc/sink - elements - -- wasapi2: Add support for process loopback capture for a specified - PID (requires Windows 11/Windows Server 2022) - -- The Windows universal UWP build is currently non-functional and will - need updating after the recent GLib upgrade. It is unclear if anyone - is using these binaries, so if you are please make yourself known. - -- wicjpegdec, wicpngdec: Windows Imaging Component (WIC) based JPEG - and PNG decoder elements. - -- mfaacdec, mfmp3dec: Windows MediaFoundation AAC and MP3 decoders - -- The uninstalled development environment supports PowerShell 7 now +- This section will be completed in due course Linux -- Improved design for DMA buffer sharing and modifier handling for - hardware-accelerated video decoders/encoders/filters and - capture/rendering on Linux and Linux-like system. - -- kmssink - - - new “fd” property which allows an application to provide their - own opened DRM device fd handle to kmssink. That way an - application can lease multiple fd’s from a DRM master to display - on different CRTC outputs at the same time with multiple kmssink - instances, for example. - - new “skip-vsync” property to achieve full framerate with legacy - emulation in drivers. - - HDR10 infoframe support - -- va plugin and gstreamer-vaapi improvements (see above) - -- waylandsink: Add “rotate-method” property and “render-rectangle” - property - -- new gtkwaylandsink element based on gtksink, but similar to - waylandsink and uses Wayland APIs directly instead of rendering with - Gtk/Cairo primitives. This approach is only compatible with Gtk3, - and like gtksink this element only supports Gtk3. +- This section will be completed in due course Documentation improvements -- The GStreamer Rust plugins are now included and documented in the - plugin documentation. +- This section will be completed in due course Possibly Breaking Changes -- the Opus audio RTP payloader and depayloader no longer accept the - lower case encoding-format=multiopus but instead produce and accept - only the upper case variant encoding-format=MULTIOPUS, since those - should always be upper case in GStreamer (caps fields are always - case sensitive). This should hopefully only affect applications - where RTP caps are set manually and multi-channel audio (>= 3 - channels) is used. - -- wpesrc: the URI handler protocols changed from wpe:// and web:// to - web+http://, web+https://, and web+file:// which means URIs are RFC - 3986 compliant and the source can simply strip the prefix from the - protocol. - -- The Windows screen capture element dxgiscreencapsrc has been - removed, please use d3d11screencapturesrc instead. - -- On Android the minimum supported Android API version is now version - 21 and has been increased from 16. - -- On macOS, the GLib version shipped with the GStreamer binaries will - no longer initialize an NSApp or run an NSRunLoop on the main - thread. See macOS/iOS section above for details. - -- decklink: The decklink plugin is now using the 12.2.2 version of the - SDK and will not work with drivers older than version 12. - -- On iOS Apple Bitcode support was removed from the binaries. This - feature is deprecated since XCode 14 and not used on the App Store - anymore. - -- The MP4/Matroska/WebM muxers now require the “stream-format” to be - provided as part of the AV1 caps as only the original “obu-stream” - format is supported in these containers and not the “annexb” format. +- This section will be completed in due course Known Issues -- The Windows UWP build in Cerbero needs fixing after the recent GLib - upgrade (see above) - -- The C# bindings have not been updated to include new 1.22 API yet - (see above) +- This section will be completed in due course Statistics -- 4072 commits +- This section will be completed in due course -- 2224 Merge Requests +Contributors -- 716 Issues +- This section will be completed in due course -- 200+ Contributors +Stable 1.24 branch -- ~33% of all commits and Merge Requests were in Rust modules +After the 1.24.0 release there will be several 1.24.x bug-fix releases which will contain bug fixes which have been deemed +suitable for a stable branch, but no new features or intrusive changes will be added to a bug-fix release usually.
