## Major new features and changes
|
||
|
||
### Discourse forum and Matrix chat space
|
||
|
||
- The new Discourse forum and Matrix chat space are now our preferred communication channels for support and developer chat.
|
||
|
||
- The mailing lists and IRC channel are on their way to being phased out, but Discourse can be used via e-mail as well.
|
||
|
||
- For release announcements please subscribe to the News + Announcements category on Discourse, although we will continue to
|
||
also send announcements to the mailing list for the time being.
|
||
|
||
### Playbin3, decodebin3 now stable and default
|
||
|
||
- After a year of stability, testing and more improvements, playbin3, and its various components (uridecodebin3, decodebin3
|
||
and urisourcebin), are now the recommended playback components.
|
||
|
||
- Some playback components have now switched to defaulting to playbin3: gst-play-1.0 and the GstPlay / GstPlayer libraries.
|
||
Application developers are strongly recommended to switch to using those components instead of the legacy playbin and
|
||
(uri)decodebin.
|
||
|
||
Improvements in this cycle:
|
||
|
||
- Better support missing/faulty decoders, attempt to use another one or gracefully un-select the stream.
|
||
|
||
- Many fixes for more complex gapless and instant-switching scenarios
|
||
|
||
- Lower latency for live pipelines
|
||
|
||
- Fix for “chained” streams (ex: Ogg, or PMT update in MPEG-TS)
|
||
|
||
- Fixes for hardware-accelerated playback with subtitles (provided the sink can handle offloading composition). This was also
|
||
partly due to a historical confusion between subtitle “decoders” (which decode the format to text and “parsers” (which only
|
||
do timing detection and optional seeking).
|
||
|
||
### GstMeta serialization/deserialization and other GstMeta improvements
|
||
|
||
- GstMeta serialization/deserialization allows metas to be transmitted or stored. This is used by the unixfd and cudaipc
|
||
plugins for inter-process communication (IPC). Implemented so far for GstCustomMeta, GstVideoMeta, GstAudioMeta and
|
||
GstReferenceTimestampMeta.
|
||
|
||
- Simplified GstCustomMeta registration with gst_meta_register_custom_simple() for the simple case where tags and transform
|
||
functions are not needed.
|
||
|
||
- GstMetaClearFunction clears the content of the meta. This will be called by buffer pools when a pooled buffer is returned to
|
||
the pool.
|
||
|
||
- Add gst_meta_info_new() and gst_meta_info_register() to register a GstMeta in two steps for easier extensibility.
|
||
|
||
### New unixfd plugin for efficient 1:N inter-process communication on Linux
|
||
|
||
- unixfdsink and unixfdsrc are elements that, inspired by shmsink andn shmsrc, send UNIX file descriptors (e.g. memfd, dmabuf)
|
||
from one sink to multiple source elements in other processes on Linux.
|
||
|
||
- The unixfdsink proposes a memfd/shm allocator to upstream elements which allows for example videotestsrc to write directly
|
||
into memory that can be transfered to other processes without copying.
|
||
|
||
### New GstMeta for SMPTE ST-291M HANC/VANC Ancillary Data
|
||
|
||
- Previously only various specific GstMeta for ancillary data were provided, such as GstVideoCaptionMeta and GstVideoAFDMeta.
|
||
The new GstAncillaryMeta allows passing arbitrary ancillary data between elements, including custom and non-standard
|
||
ancillary data. See GstAncillaryMeta for details.
|
||
|
||
- Add with gst_buffer_add_ancillary_meta() and retrieve with gst_buffer_get_ancillary_meta() or
|
||
gst_buffer_iterate_ancillary_meta().
|
||
|
||
- Supported by the newly added AJA sink and source elements
|
||
|
||
### DSD audio support
|
||
|
||
- DSD audio is a non-PCM raw audio format representation and the GstAudio library gained support for this in form of new
|
||
GstDsdInfo and GstDsdFormat API.
|
||
|
||
- Support for DSD audio has been implemented in alsasink as well as the GstAudioSink and GstAudioRingBuffer base classes, and
|
||
the gst-libav plugin to enable FFmpeg-based DSD elements and functionality.
|
||
|
||
### Analytics and Machine Learning
|
||
|
||
- A new library, GstAnalytics, has been added. It defines a GstAnalyticsRelationMeta that can efficiently hold a large number
|
||
of observations from a data analysis process, for example from machine learning. It also contains a matrix of the
|
||
relationship between those observations.
|
||
|
||
- Three types of metadata are already defined in the library: object detection, classification and tracking.
|
||
|
||
- A new objectdetectionoverlay element has been merged that draws the bounding boxes and the classes from the object detection
|
||
and classification metadata types.
|
||
|
||
- The onnxinference element has been split into two parts. The first part works with the ONNX Runtime library to do the actual
|
||
inference, while the second part called ssdobjectdetector interprets the produced tensor. This new element creates
|
||
GstAnalyticsRelationMeta.
|
||
|
||
- The onnxinference element now accepts video frames without transformation if the module declares that it accepts the “Image”
|
||
type and the format is something that GStreamer knows.
|
||
|
||
- In the next release, tensor decoders such as ssdobjectdetector will live outside of the ONNX plugin so they can be used with
|
||
other machine learning acceleration frameworks.
|
||
|
||
### Qt5 + Qt6 QML integration improvements
|
||
|
||
- The Qt5 qmlglsink, qmlgloverlay, qmlglmixer received support for directly consuming BGRA and YV12 video frames without a
|
||
prior glcolorconvert.
|
||
|
||
- New qml6glsrc, qml6glmixer, and qml6gloverlay elements as Qt6 counterparts to the existing Qt5 elements, also with support
|
||
for directly consuming BGRA and YV12 video frames without a prior glcolorconvert.
|
||
|
||
- qml6d3d11sink is a new Direct3D11 Qt6 QML sink for Windows as an alternative to the existing qml6glsink.
|
||
|
||
### DRM Modifier Support for dmabufs on Linux
|
||
|
||
The Linux dmabuf subsystem provides buffer sharing across different hardware device drivers and subsystems, and is used
|
||
extensively by the DRM subsystem to exchange buffers between processes, contexts, and library APIs within the same process, and
|
||
also to exchange buffers with other subsystems such as Linux Media.
|
||
|
||
In GStreamer, it’s used on the capture side (v4l2src, pipewire), hardware-accelerated video decoders and encoders, OpenGL
|
||
integration, Wayland renderers, etc.
|
||
|
||
GStreamer has had support for dmabufs for a long time and was able to negotiate “zero-copy” paths between different components,
|
||
however it only supported and assumed simple linear formats and was not able to negotiate complex non-linear formats. This meant
|
||
that dmabuf support actually had to be disabled in many scenarios to avoid “garbled video”.
|
||
|
||
With GStreamer 1.24 there is now full DRM modifier support and complex non-linear formats can be supported and negotiated
|
||
between components.
|
||
|
||
This is achieved with an extra drm_format field in video/x-raw(memory:DMABuf), format=(string)DMA_DRM caps, e.g.
|
||
drm-format=(string)NV12:0x0x0100000000000001.
|
||
|
||
See the GStreamer DMA buffers design documentation for more details.
|
||
|
||
This is used in the VA-API va plugin, waylandsink, the MSDK plugin, and the OpenGL integration. Video4Linux support is expected
|
||
to land in one of the next minor releases.
|
||
|
||
New API has been added for easy handling of these new caps:
|
||
|
||
- GstVideoInfoDmaDrm plus associated functions, similar to GstVideoInfo, including conversion to and from GstVideoInfo with
|
||
gst_video_info_dma_drm_from_video_info() and gst_video_info_dma_drm_to_video_info()
|
||
|
||
- GST_VIDEO_DMA_DRM_CAPS_MAKE
|
||
|
||
- GST_VIDEO_FORMAT_DMA_DRM
|
||
|
||
### OpenGL integration enhancements
|
||
|
||
- When using EGL, if both OpenGL ES and OpenGL are available, OpenGL ES is preferred over OpenGL. OpenGL ES supports some
|
||
necessary features required for dmabuf support. This does not apply if an external library/application chooses an OpenGL API
|
||
first.
|
||
|
||
- Improved support for dmabuf use cases. The glupload element now supports the new and improved dmabuf negotiation with
|
||
explicit modifiers.
|
||
|
||
- Base classes for mixing with OpenGL are now public API. GstGLBaseMixer and GstGLMixer are exposed matching the existing
|
||
filter-based GstGLBaseFilter and GstGLFilter base classes. The new OpenGL mixer base classes are based on
|
||
GstVideoAggregator.
|
||
|
||
- Add support for a ‘surfaceless’ EGL context using EGL_MESA_platform_surfaceless.
|
||
|
||
- Expose Vivante Framebuffer build-related files (pkg-config, gir) as public API
|
||
|
||
- Add support for more video formats:
|
||
|
||
- A420 8/10/12/16-bit.
|
||
- A422 8/10/12/16-bit.
|
||
- A444 8/10/12/16-bit.
|
||
- I420 10/12 bit.
|
||
- RBGA.
|
||
|
||
- Add support for tiled video formats
|
||
|
||
- NV12_16L32S (Mediatek format)
|
||
- NV12_4L4 (Verisilicon Hantro format)
|
||
|
||
- glcolorconvert now has API for retrieving shader strings for:
|
||
|
||
- swizzling (reordering components).
|
||
- YUV->RGB conversion.
|
||
- RGB->YUV conversion.
|
||
|
||
- Add more helpers for information about a particular video and/or GL format e.g. number of components, bytes used, or pixel
|
||
ordering.
|
||
|
||
- glvideomixer has new sink pad properties sizing-policy, xalign, yalign matching compositor.
|
||
|
||
- GstGLBufferPool now has a configuration option for allowing a number of buffers to be always outstanding allowing for
|
||
reducing the potential synchronisation delay when reusing OpenGL memory backed buffers.
|
||
|
||
### Vulkan integration enhancements
|
||
|
||
- Add support for the Vulkan H.264 and H.265 decoders.
|
||
|
||
- Add support for timeline semaphores.
|
||
|
||
- Optionally use newer Vulkan functions for format selection.
|
||
|
||
- Add support for GPU-assisted validation.
|
||
|
||
- Vulkan/Wayland: add support for xdg_wm_base protocol for creating a visible debug window. Required as the previous wl_shell
|
||
interface is being removed from compositors.
|
||
|
||
### CUDA / NVCODEC integration and feature additions
|
||
|
||
- New cudaipcsrc and cudaipcsink elements for zero-copy CUDA memory sharing between processes
|
||
|
||
- New nvJPEG library based nvjpegenc JPEG encoder element
|
||
|
||
- The NVIDIA desktop GPU decoder nvh264sldec, nvh265sldec, nvvp8sldec, and nvvp9sldec elements were renamed to nvh264dec,
|
||
nvh265dec, nvvp8dec, and nvvp9dec, respectively.
|
||
|
||
- GStreamer NVIDIA H.264 and H.265 encoders except for nvh264enc and nvh265enc gained support for CEA708 Closed Caption
|
||
inserting.
|
||
|
||
- OpenGL memory support is added to nv{cuda,autogpu}h264enc and nv{cuda,autogpu}h265enc elements
|
||
|
||
- CUDA stream integration: As of 1.24, CUDA stream synchronization is an application’s responsibility, and GStreamer will not
|
||
execute unnecessary synchronization operations. If an application needs direct access to CUDA memory via GST_MAP_CUDA map
|
||
flag, cuStreamSynchronize() or gst_cuda_memory_sync() call is required unless application-side CUDA operation is executed
|
||
with the GstCudaMemory’s associated CUDA stream.
|
||
|
||
### RTP stack improvements
|
||
|
||
- New rtppassthroughpay element which just passes RTP packets through unchanged, but appears like an RTP payloader element.
|
||
This is useful for relaying an RTP stream as-is through gst-rtsp-server, which expects an RTP payloader with certain
|
||
properties at the end of an RTSP media sub-pipeline.
|
||
|
||
- New “timeout-inactive-rtp-sources” property on rtpbin, sdpdemux and rtpsession to allow applications to disable automatic
|
||
timeout of sources from which no data has been received for a while.
|
||
|
||
- rtpvp8pay, rtpvp9pay: expose “picture-id” as a property, and add a “picture-id-offset” property to the VP9 payloader to
|
||
bring it in line with the VP8 payloader.
|
||
|
||
- rtpjitterbuffer has seen improved media clock handling (clock equality and clock setting/resetting), as well as two new
|
||
properties that allow reconstruction of absolute PTP timestamps without actually syncing to the PTP clock, which can be
|
||
useful in scenarios where one wants to reconstruct the absolute PTP clock timestamps on a machine that doesn’t have access
|
||
to the network of the PTP clock provider. The two new properties are:
|
||
|
||
- “rfc7273-use-system-clock”: allows the jitter buffer to assume that the system clock is synced sufficiently close to the
|
||
media clock used by an RFC7273 stream. By default the property is disabled and the jitter buffer will create a media
|
||
clock and try to sync to it, but this is only required to determine in which wraparound period from the media clock’s
|
||
Epoch the current RTP timestamps refer to (and thus to reconstruct absolute time stamps from them). If the property is
|
||
enabled the wraparound period and current offset from the Epoch will be determined based on the local system clock,
|
||
which means that no direct network connection to the media clock provider is needed to reconstruct absolute timestamps.
|
||
There is also no start-up delay, because there’s no clock sync that needs to be established first.
|
||
|
||
- “rfc7273-reference-timestamp-meta-only”: If this property is enabled then the jitter buffer will do the normal timestamp
|
||
calculations for the output buffers according to the configured mode instead of making use of the RFC7273 media clock
|
||
for that. It will still calculate RFC7273 media clock timestamps, but only attach them to the output buffers in form of
|
||
a clock reference meta.
|
||
|
||
- RTP payloaders and depayloaders now have an “extensions” property for retrieving the list of currently enabled RTP header
|
||
extensions.
|
||
|
||
- rtpbin and webrtcbin no longer blindly set properties on the jitter buffer assuming it’s a standard rtpjitterbuffer, but
|
||
instead check if the property is available first, to better support non-standard jitterbuffers or even an identity element
|
||
in lieu of a jitter buffer.
|
||
|
||
- RTP header extension handling fixes for depayloaders that aggregate multiple input buffers into a single output buffer.
|
||
Before, only the last RTP input buffer was checked for header extensions. Now the depayloader remembers all RTP packets
|
||
pushed before an output buffer is produced and checks all RTP input buffers for header extensions.
|
||
|
||
- Affected depayloaders: rtph264depay, rtph265depay, rtpvp8depay, rtpvp9depay, rtpxqtdepay, rtpasfdepay, rtpmp4gdepay,
|
||
rtpsbcdepay, rtpvorbisdepay, rtpmp4vdepay, rtptheoradepay, rtpsv3vdepay, rtpmp4adepay, rtpklvdepay, rtpjpegdepay,
|
||
rtpj2kdepay, rtph263pdepay, rtph263depay, rtph261depay. rtpgstdepay.
|
||
|
||
### WebRTC improvements
|
||
|
||
- Add support for ICE consent freshness (RFC 7675). This requires libnice >= 0.1.22.
|
||
|
||
- Advertise the local side of an end-of-candidates with an empty candidate string.
|
||
|
||
- Add the number of Data Channels opened and closed to webrtcbin’s statistics.
|
||
|
||
- Various improvements and feature additions in the Rust webrtc plugin, which provides webrtcsrc and webrtcsink elements as
|
||
well as specific elements for different WebRTC signalling protocols. See the Rust plugins section below for more details.
|
||
|
||
### Adaptive Streaming improvements and Low-Latency HLS (LL-HLS) support
|
||
|
||
- hlsdemux2 now supports Low-Latency HLS (LL-HLS)
|
||
|
||
- hlsdemux2 asynchronous playlist download and update improves responsiveness and bandwith usage.
|
||
|
||
- hlsdemux2 handles fallback variant URLs.
|
||
|
||
- hlsdemux2 is more responsive and accurate when handling seeks.
|
||
|
||
- dashdemux2 and hlsdemux2 have a new “start-bitrate” property, improving the decision for which initial stream variant that
|
||
will be used.
|
||
|
||
- dashdemux2, hlsdemux2, mssdemux2 have received many improvements regarding seeking, along with support for “early-seek”
|
||
which allows playback to start immediately from the requested position without any previous download.
|
||
|
||
- dashdemux2, hlsdemux2, mssdemux2 better handle errors on or near the live edge.
|
||
|
||
- dashsink can now use the dashmp4mux muxer from the Rust plugins and will also produce better and RFC 6381-compatible codec
|
||
strings. The “suggested-presentation-delay” property allows to set the suggested presentation delay in the MPD.
|
||
|
||
- No development took place on the legacy demuxers (dashdemux, hlsdemux, mssdemux). Application developers are reminded to use
|
||
the new demuxers instead. They are automatically picked up when using urisourcebin, uridecodebin3 or playbin3.
|
||
|
||
### W3C Media Source Extensions library
|
||
|
||
- A new GStreamer library (mse) implementing the W3C Media Source Extensions specification was added.
|
||
|
||
- Applications can embed this library along with GStreamer in order to integrate software that uses the Media Source APIs
|
||
without relying on a web browser engine. Typically an application consuming this library will wrap the C API with JavaScript
|
||
bindings that match the Media Source API so their existing code can integrate with this library.
|
||
|
||
### Closed Caption handling improvements
|
||
|
||
- ccconverter supports converting between the two CEA-608 fields.
|
||
|
||
- New cea608mux element for muxing multiple CEA-608 streams together.
|
||
|
||
- Various improvements and feature additions in the Rust-based closed caption elements. Check out the Rust plugins section
|
||
below for more details.
|
||
|
||
### Precision Time Protocol (PTP) clock improvements
|
||
|
||
- Many fixes and compatibility/interoperability improvements.
|
||
|
||
- Better support for running on devices with multiple network interfaces.
|
||
|
||
- Allow sync to master clock on same host.
|
||
|
||
- PTP clock support is now also available on Windows.
|
||
|
||
- The standalone ptp-helper binary has been rewritten in Rust for portability and security. This works on Linux, Android,
|
||
Windows, macOS, FreeBSD, NetBSD, OpenBSD, DragonFlyBSD, Solaris and Illumos. Newly supported compared to the C version is
|
||
Windows. Compared to the C version various error paths are handled more correctly and a couple of memory leaks are fixed.
|
||
Otherwise it should work identically. The minimum required Rust version for compiling this is 1.48, i.e. the version
|
||
currently in Debian oldstable. On Windows, Rust 1.54 is needed at least.
|
||
|
||
- New ptp-helper Meson build option so PTP support can be disabled or required.
|
||
|
||
- gst_ptp_init_full() allows for a more fine-grained and extensible configuration and initialization of the GStreamer PTP
|
||
subsystem, including TTL configuration.
|
||
|
||
### Bayer 10/12/14/16-bit depth support
|
||
|
||
- bayer2rgb and rgb2bayer now support bayer with 10/12/14/16 bit depths
|
||
|
||
- v4l2src and videotestsrc now support bayer with 10/12/14/16 bit depths
|
||
|
||
- imagefreeze gained bayer support as well
|
||
|
||
### MPEG-TS improvements
|
||
|
||
- mpegtsdemux gained support for
|
||
- segment seeking for seamless non-flushing looping, and
|
||
- synchronous KLV
|
||
- mpegtsmux now
|
||
- allows attaching PCR to non-PES streams
|
||
- allows setting of the PES stream number for AAC audio and AVC video streams via a new “stream-number” property on the
|
||
muxer sink pads. Currently the PES stream number is hard-coded to zero for these stream types.
|
||
- allows writing arbitrary Opus channel mapping families and up to 255 channels
|
||
- separate handling of DVB and ATSC AC3 descriptors
|
||
|
||
## New elements and plugins
|
||
|
||
- analyticsoverlay visualises object-detection metas on a video stream.
|
||
|
||
- autovideoflip and autodeinterlace are two new auto elements.
|
||
|
||
- AJA source and sink elements plus device provider for AJA capture and playout cards, including support for HANC/VANC
|
||
ancillary data.
|
||
|
||
- New cea608mux element for muxing multiple CEA-608 streams together.
|
||
|
||
- The codec2json plugin adds av12json, h2642json, h2652json and vp82json elements which convert AV1, H.264, H.265 and VP8
|
||
frame parameters into human readable JSON data, which is useful for debugging and testing purposes.
|
||
|
||
- New lc3 plugin with a decoder and encoder for the Bluetooth LC3 audio codec.
|
||
|
||
- New onnxinference element to run ONNX inference models on video buffers.
|
||
|
||
- New rtppassthroughpay element which just passes RTP packets through unchanged, but appears like an RTP payloader element.
|
||
This is mostly useful for medias that simply pass through an existing RTP stream in gst-rtsp-server.
|
||
|
||
- Qt6: qml6glsrc, qml6glmixer, qml6gloverlay, and qml6d3d11sink
|
||
|
||
- New SVT-AV1 encoder plugin, imported from SVT-AV1 but with many fixes.
|
||
|
||
- Many exciting new Rust elements, see Rust section below.
|
||
|
||
- New DirectWrite text rendering and Direct3D12 plugins (see Windows section below).
|
||
|
||
- New vaav1enc element for encoding video in AV1 (See VA-API section)
|
||
|
||
- New uvcsink element for exporting streams as UVC camera
|
||
|
||
## New element features and additions
|
||
|
||
- alphacombine supports I420_10LE now for 10-bit WebM/alpha support.
|
||
|
||
- The amfcodec for hardware-accelerated video encoding using the Advanced Media Framework (AMF) SDK for AMD GPUs gained some
|
||
new features:
|
||
|
||
- 10-bit and HDR support for H.265 / HEVC and AV1 video encoders
|
||
- B-frame support in the H.264 encoder
|
||
- Initial support of pre-analysis and pre-encoding
|
||
- Initial support of Smart Access Video for optimal distribution amongst multiple AMD hardware instances.
|
||
|
||
- appsink: new “propose-allocation” signal so applications can provide a buffer pool or allocators to the upstream elements,
|
||
as well as “max-time” and “max-buffers” properties to configure the maximum size of the appsink-internal queue in addition
|
||
to the existing “max-bytes” property.
|
||
|
||
- autovideoconvert exposes colorspace and scaler elements for well know elements
|
||
|
||
- avtp: add AVTP Raw Video Format payload and de-payload support.
|
||
|
||
- cacasink’s output driver can now be selected via the “driver” property.
|
||
|
||
- camerabin: various fixes and stability improvements
|
||
|
||
- clocksync: “QoS” property to optionally send QoS events upstream like a synchronising sink would.
|
||
|
||
- cutter: can add GstAudioLevelMeta on output buffers, which can be enabled via the new “audio-level-meta” property.
|
||
|
||
- dashdemux2 has a new “start-bitrate” property.
|
||
|
||
- dashsink can now use the dashmp4mux muxer from the Rust plugins and will also produce better and RFC 6381-compatible codec
|
||
strings. The “suggested-presentation-delay” property allows to set the suggested presentation delay in the MPD.
|
||
|
||
- deinterlace: Add support for 10/12/16-bit planar YUV formats
|
||
|
||
- The dvdspu subpicture overlay now implements GstVideoOverlayComposition support to make it work better with hardware
|
||
decoders where the video data should ideally stay on the GPU/VPU and the overlay blitting be delegated to the renderer.
|
||
|
||
- encodebin now automatically autoplugs timestamper elements such as h264timestamper or h265timestamper, based on new
|
||
“Timestamper” element factory type and rank.
|
||
|
||
- New fakevideodec element (see debugging section below).
|
||
|
||
- filesink: “file-mode” property to allow the ability to specify rb+ file mode, which overwrites an existing file. This is
|
||
useful in combination with splitmuxsink so that files can be pre-allocated which can be useful to reduce disk fragmentation
|
||
over time.
|
||
|
||
- flvmux: add “enforce-increasing-timestamps” property to allow disabling a hack that was added back in the day because
|
||
librtmp as used in rtmpsink would get confused by timestamps going backwards, but this is no longer required with rtmpsink2.
|
||
If set to true (still the default, for backwards compatibility), flvmux will modify buffers timestamps to ensure they are
|
||
always strictly increasing, inside one stream and also between the audio and video streams.
|
||
|
||
- giostreamsink: Add a property to close the stream on stop().
|
||
|
||
- h264parse improved its AU boundary detection.
|
||
|
||
- h264parse, h265parse, mpegvideoparse now support multiple unregistered user data SEI messages.
|
||
|
||
- insertbin is now a registered element and available via the registry, so can be constructed via parse-launch and not just
|
||
via the insertbin API.
|
||
|
||
- jack: libjack is now loaded dynamically at runtime instead of linking it at build time. This means the plugin can be shipped
|
||
on Windows and macOS and will work if there’s a user-installed JACK server/library setup.
|
||
|
||
- jpegparse now has a rank so it will be autoplugged if needed.
|
||
|
||
- kmssink: Add auto-detection for NXP i.MX8M Plus LCDIFv3, ST STM32 LTDC, and Texas Instruments TIDSS display controllers.
|
||
|
||
- matroskademux and matroskamux gained support for more raw video formats, namely RGBA64_LE, BGRA64_LE, GRAY10_BE32, GRAY16_LE
|
||
|
||
- mpg123audiodec’s rank was changed from MARGINAL to PRIMARY so it’s now higher than avdec_mp3, as it works better with
|
||
“freeformat” MP3s.
|
||
|
||
- msdk:
|
||
|
||
- DRM modifier support on Linux
|
||
|
||
- only expose codecs and capabilities actually supported by the platform
|
||
|
||
- msdkvpp video post-processing:
|
||
|
||
- new “hdr-tone-mapping” property to enable HDR-to-SDR tone mapping
|
||
- new compute scaling mode
|
||
|
||
- Decoders sport D3D11 and VA integration, and the VP9 decoder supports certain resolution changes.
|
||
|
||
- Encoders:
|
||
|
||
- msdkh264enc, msdkh265enc**: “pic-timing-sei” property to insert pic timing SEI
|
||
- msdkh264enc, msdkh265enc**: Add properties to allow different max/min-qp values for I/P/B frames
|
||
- msdkh264enc: Added BGRx format DMABuf support
|
||
- Advertise special image formats in low power mode
|
||
|
||
- mxfdemux gained support for FFV1 demuxing
|
||
|
||
- opusenc, opusdec now support decoding and encoding more than 8 channels, and can also handle unknown/unpositioned channel
|
||
layouts.
|
||
|
||
- The oss plugin gained a device provider for audio device discovery
|
||
|
||
- pcapparse learned how to handle the Linux “cooked” capture encapsulation v2
|
||
|
||
- Intel Quick Sync plugin improvements:
|
||
|
||
- qsvh264enc gained more encoding options
|
||
- qsvh265dec now supports GBR decoding and HEVC RExt profiles
|
||
|
||
- qtdemux now adds audio clipping meta when playing gapless m4a content, supports CENC sample grouping, as well as the SpeedHQ
|
||
video codec.
|
||
|
||
- ristsrc gained support for dynamic payloads via the new “caps” and “encoding-name” properties. These can be used to make the
|
||
ristsrc receive other payload types than MPEG-TS.
|
||
|
||
- rtmp2src: a new “no-eof-is-error” property was added: There is currently no way for applications to know if the stream has
|
||
been properly terminated by the server or if the network connection was disconnected, as an EOS is sent in both cases. With
|
||
the property set, connection errors will be reported as errors, allowing applications to distinguish between both scenarios.
|
||
|
||
- rtspsrc: new “extra-http-request-headers” property for adding custom http request headers when using http tunnelling.
|
||
|
||
- sdpdemux now supports SDP source filters as per RFC 4570; audio-only or video-only streaming can be selected via the new
|
||
“media” property, and RTCP feedback can be disabled via the “rtcp-mode” property.
|
||
|
||
- splitmuxsrc uses natural ordering to sort globbed filenames now, i.e. 0, 1, 2, 10, 11 instead of 0, 1, 10, 11, 2, …
|
||
|
||
- srt: Add more fields to the statistics to see how many packets were retransmitted and how many were dropped.
|
||
|
||
- switchbin: many improvements, especially for caps handling and passthrough.
|
||
|
||
- taginject: a “scope” property was added to allow injection of global tags in addition to the current default which is stream
|
||
tags.
|
||
|
||
- timeoverlay: add buffer-count and buffer-offset time modes.
|
||
|
||
- udpsrc: new “multicast-source” property to support IGMPv3 Source Specific Muliticast (SSM) as per RFC 4604.
|
||
|
||
- videoconvertscale, videoconvert: add a “converter-config” property to allow fine-tuning conversion parameters that are not
|
||
exposed directly as property.
|
||
|
||
- videoflip: many orientation tag handling fixes and improvements
|
||
|
||
- videorate: add “drop-out-of-segment” property to force dropping of out-of-segment buffers.
|
||
|
||
- volume now supports arbitrarily-large positive gains via a new “volume-full-range” property (it was not possibly to just
|
||
allow a bigger maximum value for the existing “volume” property for GstController-related backwards-compatibility reasons).
|
||
|
||
- waylandsink, gtkwaylandsink: improved frame scheduling reducing frame drops and improve throughput.
|
||
|
||
- webpenc now has support for animated WebP which can be enabled via the new “animated” property. By default it will just
|
||
output a stand-alone WebP image for each input buffer, just like before.
|
||
|
||
- wpe: added a WebProcess crash handler; gained WPEWebKit 2.0 API support.
|
||
|
||
- x264enc gained support for 8-bit monochrome video (GRAY8).
|
||
|
||
- ximagesrc gained navigation support (mouse and keyboard events).
|
||
|
||
- y4mdec now parses extended headers to support high bit depth video.
|
||
|
||
## Plugin and library moves
|
||
|
||
- The AMR-NB and AMR-WB plugins have been moved from -ugly to -good.
|
||
|
||
## Plugin and element removals
|
||
|
||
- The entire gst-omx package and plugin has been retired. See the OMX section below for more details.
|
||
|
||
- The RealServer RTSP extension, RDT handling and PNM source have been removed from the realmedia plugin.
|
||
|
||
- The kate subtitle plugin has been removed.
|
||
|
||
## Miscellaneous API additions
|
||
|
||
GStreamer Core
|
||
|
||
- gst_pipeline_get_configured_latency() and gst_pipeline_is_live() convenience functions to query liveness and configured
|
||
latency of a pipeline.
|
||
|
||
- Plugins can now provide status info messages for plugins that will be displayed in gst-inspect-1.0 and is useful for dynamic
|
||
plugins that register features at runtime. They are now able to provide information to the user why features might not be
|
||
available. This is now used in the amfcodec, nvcodec, qsv, and va plugins.
|
||
|
||
- GST_OBJECT_AUTO_LOCK() and GST_PAD_STREAM_AUTO_LOCK() are g_autoptr(GMutexLocker)-based helpers for GstPad and GstObject
|
||
that unlock the mutex automatically when the helper goes out of scope. This is not portable so should not be used in
|
||
GStreamer code that needs to be portable to e.g. Windows with MSVC.
|
||
|
||
- gst_clear_context(), gst_clear_promise(), gst_clear_sample()
|
||
|
||
- gst_util_ceil_log2() and gst_util_simplify_fraction() utility functions
|
||
|
||
- New TAG_CONTAINER_SPECIFIC_TRACK_ID tag for container specific track ID as used in an HTML5 context, plus basic support in
|
||
matroskademux, qtdemux, dashdemux and dashdemux2
|
||
|
||
- New utility functions to create a stream-id without a pad for elements:
|
||
|
||
- gst_element_decorate_stream_id()
|
||
- gst_element_decorate_stream_id_printf_valist()
|
||
- gst_element_decorate_stream_id_printf()
|
||
|
||
- GstQueueArray gained API for sorting and sorted insertion
|
||
|
||
- Add strict GstStructure serialisation with gst_structure_serialize_full() in combination with GST_SERIALIZE_FLAG_STRICT
|
||
which only succeeds if the result can later be fully deserialised again.
|
||
|
||
- GstBaseSrc enhancements: the “automatic-eos” property can be used to do the equivalent to gst_base_src_set_automatic_eos().
|
||
gst_base_src_push_segment() sends a segment event right away which can be useful for subclasses like appsrc which have their
|
||
own internal queuing.
|
||
|
||
- GstBaseSink gained a new custom GST_BASE_SINK_FLOW_DROPPED flow return which can be used by subclasses from the virtual
|
||
::render method to signal to the base class that a frame is not being rendered. This is used in e.g. waylandsink and ensures
|
||
that elements such as fpsdisplaysink will correctly report the rate of frames rendered and dropped.
|
||
|
||
GstDiscoverer
|
||
|
||
- New “load-serialized-info” signal to retrieve a serialized GstDiscovererInfo
|
||
|
||
GstSDP
|
||
|
||
- Add gst_sdp_message_remove_media()
|
||
|
||
Video Library
|
||
|
||
DRM Modifier Support for dmabufs on Linux
|
||
|
||
See section above.
|
||
|
||
List of Video Formats for Passthrough
|
||
|
||
New helper API was added to get a list of all supported video formats, including DMA_DRM formats, and can be used to advertise
|
||
all supported formats for passthrough purposes:
|
||
|
||
- GST_VIDEO_FORMATS_ANY_STR, GST_VIDEO_FORMATS_ANY
|
||
- gst_video_formats_any() which can be used by bindings or for code that prefers GstVideoFormat values instead of strings.
|
||
|
||
New Video Formats
|
||
|
||
- 12-bit and 16-bit A420 / A422 / A444 (YUV with alpha channel) variants:
|
||
|
||
- A444_12BE, A444_12LE
|
||
- A422_12BE, A422_12LE
|
||
- A420_12BE, A420_12LE
|
||
- A444_16BE, A444_16LE
|
||
- A422_16BE, A422_16LE
|
||
- A420_16BE, A420_16LE
|
||
|
||
- 8-bit A422 / A444 (YUV with alpha channel) variant:
|
||
|
||
- A422
|
||
- A444
|
||
|
||
- Planar 16-bit 4:4:4 RGB formats:
|
||
|
||
- GBR_16BE
|
||
- GBR_16LE
|
||
|
||
- RBGA, intended to be used by hardware decoders where VUYA is only supported 4:4:4 decoding surface but the stream is encoded
|
||
with GBR color space, such as HEVC and VP9 GBR streams for example.
|
||
|
||
- Two tiled Mediatek 10-bit formats:
|
||
|
||
- MT2110T
|
||
- MT2110R
|
||
|
||
- Tiled 10-bit NV12 format NV12_10LE40_4L4 (Verisilicon Hantro)
|
||
|
||
## Miscellaneous performance, latency and memory optimisations
|
||
|
||
- liborc 0.4.35 (latest: 0.4.38) adds support for AVX/AVX2 and contains improvements for the SSE backend.
|
||
|
||
- liborc 0.4.37 adds support for NEON on macOS on Apple ARM64 CPUs.
|
||
|
||
- Most direct use of the GLib GSLice allocator has been removed, as there is little evidence that it actually still provides
|
||
much advantage over the standard system allocator on Linux or Windows in 2024. There is strong evidence however that it
|
||
causes memory fragmentation for standard GStreamer workloads such as RTSP/RTP/WebRTC streaming.
|
||
|
||
- As always there have been plenty of performance, latency and memory optimisations all over the place.
|
||
|
||
## Tracing framework and debugging improvements
|
||
|
||
- The gst-stats tool can now be passed a custom regular expression
|
||
|
||
- gst-debug-viewer from the devtools module has seen minor improvements and fixes
|
||
|
||
New tracers
|
||
|
||
- None in this release.
|
||
|
||
Debug logging system improvements
|
||
|
||
- Nothing major in this cycle.
|
||
|
||
Fake video decoder
|
||
|
||
- The new fakevideodec element does not decode the input bitstream, it only reads video width, height and framerate from the
|
||
caps and then pushes out raw video frames of the expected size in RGB format.
|
||
|
||
- It draws a snake moving from left to right in the middle of the frame, which is reasonably light weight and still provides
|
||
an idea about how smooth the rendering is.
|
||
|
||
## Tools
|
||
|
||
- gst-launch-1.0 gained a new --prog-name command line option to set the program name, which will be used by GTK and GStreamer
|
||
to set the class or app-id.
|
||
|
||
- gst-play-1.0 now defaults to using playbin3, but can still be made to use the old playbin by passing the --use-playbin2
|
||
command line argument.
|
||
|
||
## GStreamer FFmpeg wrapper
|
||
|
||
- New avvideocompare element to compare two incoming video buffers using a specified comparison method (e.g. SSIM or PSNR).
|
||
|
||
- Prefer using FFmpeg Musepack decoder/demuxer over musepackdec as they work better with decodebin3 and playbin3 which likes
|
||
to have parsers and decoders separate.
|
||
|
||
- Added codec mappings for AV1, MxPEG, FFVHuff video
|
||
|
||
- Added raw video format support for P010, VUYA, Y410, P012, Y212 and Y412.
|
||
|
||
- Newer, non-deprecated APIs are used by the plugin when built with FFmpeg 6.0 or newer.
|
||
|
||
- The FFmpeg meson subproject wrap has been updated to v6.1
|
||
|
||
- Note: see Known Issues section below for known issues with FFmpeg 6.0.0 and the latest FFmpeg 7.x release
|
||
|
||
## GStreamer RTSP server
|
||
|
||
- New “ensure-keyunit-on-start” property: While the suspend modes NONE and PAUSED provided a low startup latency for
|
||
connecting clients, it did not ensure that streams started on fresh data. With this new property it is possible to maintain
|
||
the low startup latency of those suspend modes while also ensuring that a stream starts on a key unit. Furthermore, by
|
||
setting the new “ensure-keyunit-on-start-timeout” property it is also possible to accept a key unit of a certain age, but
|
||
discard it if too much time has passed and instead force a new key unit.
|
||
|
||
- rtspclientsink: apply “port-range” property for RTCP port selection as well
|
||
|
||
## GStreamer VA-API support
|
||
|
||
GstVA
|
||
|
||
- vah264dec, vah265dec, vavp8dec, vavp9dec, vampeg2dec and vaav1dec were promoted to rank PRIMARY+1 on Linux
|
||
|
||
- Improved support for dmabuf use cases. All va elements now negotiate the new and improved dmabuf capabilities with explicit
|
||
modifiers. This supports both import and export of dmabufs.
|
||
|
||
- Added vaav1enc element, available in recent Intel and AMD GPUs
|
||
|
||
- Added support for the experimental VA-Win32 backend. It needs at least libva 1.18
|
||
|
||
- Improved handling of multi-GPU systems. Still, sharing buffers among them is not advised.
|
||
|
||
- Bumped minimum libva version to 1.12
|
||
|
||
- Enhanced support for RadeonSI Mesa driver for 10bit decoding
|
||
|
||
- Register elements only for allowed drivers (Intel and Mesa, for the moment)
|
||
|
||
GStreamer-VAAPI
|
||
|
||
- The new GstVA elements (see above) should be preferred when possible.
|
||
|
||
- Ranks of decoders were demoted to NONE so they won’t be used automatically by playbin and similar elements anymore.
|
||
|
||
- Clean-ups and minimal fixes.
|
||
|
||
- gstreamer-vaapi should be considered deprecated and may be discontinued as soon as the va plugin is fully feature
|
||
equivalent. Users who rely on gstreamer-vaapi are encouraged to migrate and test the va elements at the earliest
|
||
opportunity.
|
||
|
||
## GStreamer Video4Linux2 support
|
||
|
||
- New uvcsink element, based on v4l2sink allow streaming your pipeline as a UVC camera using Linux UVC Gadget driver.
|
||
|
||
- v4l2src now supports 10/12/14/16-bit bayer formats.
|
||
|
||
- Stateful decoders now pass too large encoded frames over multiple buffers.
|
||
|
||
- AV1 Stateless video decoder.
|
||
|
||
- Stateless decoders now tested using Virtual driver (visl), making it possible to run the tests in the cloud based CI
|
||
|
||
## GStreamer OMX
|
||
|
||
- The gst-omx module has been removed. 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.
|
||
|
||
- Hardware vendors which still use OpenMAX are known to have non-standard forks and it is recommended that they maintain it
|
||
while planning their move to the Video4Linux API.
|
||
|
||
## GStreamer Editing Services and NLE
|
||
|
||
- Implement a gesvideoscale effect which gives user the ability to chooses where a clip has to be scaled in the chain of
|
||
effects. By default scaling is done in the compositor.
|
||
|
||
- Add support for gessrc as sub-timeline element so third party can implement their own formatters and use their timelines as
|
||
sub-timelines. Before that, only timelines serialized as files on the filesystem could be loaded as sub-timelines (using
|
||
gesdemux).
|
||
|
||
- Implement a new GESDiscovererManager singleton object making management of the discoverers used to discoverer media files
|
||
cleaner and allowing to expose the following APIs:
|
||
|
||
- load-serialize-info signal so GstDiscovererInfo can be serialized by users the way they like and load them without
|
||
requiring discovering the file when reloading a project.
|
||
- source-setup signal so user can tweak source elements during discovery
|
||
|
||
- Expose GESFrameCompositionMeta in public API so user can implement their own effects targetting GES which take into account
|
||
that meta.
|
||
|
||
- Expose audioconvert:mix-matrix property in audio sources
|
||
|
||
- Port GESPipeline rendering to use encodebin2. This allows rendering timelines directly with a muxing sink (like hlssinkX
|
||
etc..) and leverage all new features of that new element.
|
||
|
||
ges-launch
|
||
|
||
- Fix setting keyframes
|
||
|
||
- Add an ignore-eos option
|
||
|
||
- Allow overriding container profile so that the user can build encoding profiles following the media format of a specific
|
||
media file, for example, but ensuring it is muxed using a specific format
|
||
|
||
- Ensure sink elements are inside a GstBin and never in a GstPipeline
|
||
|
||
- Move +effect stack effects from source to last effect added, so it feels more natural to user as adding them at the
|
||
beginning of the chain while the syntax is +effect felt wrong
|
||
|
||
## GStreamer validate
|
||
|
||
- In action types, add a way to avoid checking property value after setting it, in case elements do it async for example.
|
||
|
||
- Add a vmethod to free GstValidateActionParameters to be more binding friendly.
|
||
|
||
- Allow scenarios to define the pipeline state target in the metadata instead of assuming PLAYING state.
|
||
|
||
- Add support to run sub-pipelines/scenarios
|
||
|
||
- Added support to forward buffers from appsink to appsrc
|
||
|
||
- Add a way to set pipeline base-time, start-time and force using the system clock.
|
||
|
||
- Add a ‘fill-mode’ to the appsrc-push action type so we can create some type of streams easily using an appsrc, giving
|
||
control when writing scenarios without requiring files with the content.
|
||
|
||
- Add a “select-streams” action type to test “stream aware” elements.
|
||
|
||
- Add a way to wait for a property to reach a specified value before executing an action. For example it is possible to wait
|
||
for a pad to get some specific caps set before executing an action.
|
||
|
||
- validate: Add support to replace variables in deeply nested structures in particular for more complex action types where
|
||
some of the properties are inside structures.
|
||
|
||
- Fixed compatibility with Python 3.12.
|
||
|
||
## GStreamer Python Bindings
|
||
|
||
gst-python is an extension of the regular GStreamer Python bindings based on gobject-introspection information and PyGObject,
|
||
and provides “syntactic sugar” in form of overrides for various GStreamer APIs that makes them easier to use in Python and more
|
||
pythonic; as well as support for APIs that aren’t available through the regular gobject-introspection based bindings, such as
|
||
e.g. GStreamer’s fundamental GLib types such as Gst.Fraction, Gst.IntRange etc.
|
||
|
||
- Added a GstTagList override that makes a tag list act like a dict
|
||
|
||
- Fix build and usage in Windows
|
||
|
||
- Various fixes for Python >= 3.12
|
||
|
||
- Rework libpython loading to be relocatable
|
||
|
||
- Fix libpython dlopen on macOS
|
||
|
||
## GStreamer C# Bindings
|
||
|
||
- The GStreamer C# bindings have been updated to a more recent version of GtkSharp and the bindings have been regenerated with
|
||
that version.
|
||
|
||
- GStreamer API added in recent GStreamer releases is now available
|
||
|
||
- GstRtspServer bindings have been added, plus an RTSP server example
|
||
|
||
## GStreamer Rust Bindings and Rust Plugins
|
||
|
||
The GStreamer Rust bindings and plugins are released separately with a different release cadence that’s tied to the twice-a-year
|
||
GNOME release cycle.
|
||
|
||
The latest release of the bindings (0.22) has already been updated for the new GStreamer 1.24 APIs, and works with any GStreamer
|
||
version starting at 1.14.
|
||
|
||
gst-plugins-rs, the module containing GStreamer plugins written in Rust, has also seen lots of activity with many new elements
|
||
and plugins. The GStreamer 1.24 binaries track the 0.12 release series of gst-plugins-rs, and fixes from newer versions will be
|
||
backported as needed to the 0.12 brach for future 1.24.x bugfix releases.
|
||
|
||
Rust plugins can be used from any programming language. To applications they look just like a plugin written in C or C++.
|
||
|
||
### WebRTC
|
||
|
||
- New element webrtcsrc that can act as a recvonly WebRTC client. Just like the opposite direction, webrtcsink, this can
|
||
support various different WebRTC signalling protocols. Some are included with the plugin and provide their own element
|
||
factory for easier usage but it is also possible for applications to provide new signalling protocol implementations.
|
||
|
||
- webrtcsink now exposes the signaller as property and allows implementing a custom signaller by connecting signal handlers to
|
||
the default signaller.
|
||
|
||
- A new signaller and webrtcsink implementation for Janus’ VideoRoom implementation. The corresponding webrtcsrc signaller
|
||
implementation is currently in a merge request in GitLab.
|
||
|
||
- New whepsrc element that can receive WHEP WebRTC streams. This is currently not based on webrtcsrc but in the future a new
|
||
element around webrtcsrc will be added.
|
||
|
||
- New whipserversrc element around webrtcsrc for ingesting WHIP WebRTC streams in GStreamer.
|
||
|
||
- New whipclientsink element around webrtcsink for publishing WHIP WebRTC streams from GStreamer. This deprecates the old
|
||
whipsink element.
|
||
|
||
- A new signaller and webrtcsink implementation for LiveKit. The corresponding webrtcsrc signaller implementation was merged
|
||
into the git repository recently.
|
||
|
||
- A new signaller and webrtcsink implementation for AWS Kinesis Video Streams
|
||
|
||
- webrtcsink has a new payloader-setup signal to allow the application more fine grained control over the RTP payloader
|
||
configuration, similar to the already existing encoder-setup signal for encoders.
|
||
|
||
- webrtcsrc gained support for a custom navigation event protocol over the data channel, which is compatible with the
|
||
navigation event protocol supported by webrtcsink.
|
||
|
||
- webrtcsink supports encoded streams as input. Using encoded streams will disable webrtcsinks congestion control changing any
|
||
encoded stream parameters.
|
||
|
||
- webrtcsink and webrtcsrc have a new signal ‘request-encoded-filter’ to allow transformations of the encoded stream. This can
|
||
be used, for example, for the same use-cases as the WebRTC Insertable Streams API.
|
||
|
||
- gstwebrtc-api: JavaScript API for interacting with the default signalling protocol used by webrtcsink / webrtcsrc.
|
||
|
||
… and various other smaller improvements!
|
||
|
||
### RTSP
|
||
|
||
- New rtspsrc2 element. Only a subset of RTSP features are implemented so far:
|
||
- RTSP 1.0 support
|
||
- TCP, UDP, UDP-Multicast lower transports
|
||
- RTCP SR, RTCP RR, RTCP-based A/V sync
|
||
- Tested for correctness in multicast cases too
|
||
- Lower transport selection and order (NEW!)
|
||
- The existing rtspsrc has a hard-coded order list for lower transports
|
||
- Many advanced features are not implemented yet, such as non-live support. See the README for the current status.
|
||
|
||
### GTK4
|
||
|
||
- Support for rendering GL textures on X11/EGL, X11/GLX, Wayland, macOS, and WGL/EGL on Windows.
|
||
|
||
- Create a window for testing purposes when running in gst-launch-1.0 or if GST_GTK4_WINDOW=1 is set.
|
||
|
||
- New background-color property for setting the color of the background of the frame and the borders, if any. This also allows
|
||
setting a fully transparent background.
|
||
|
||
- New scale-filter property for defining how to scale the frames.
|
||
|
||
- Add Python example application to the repository.
|
||
|
||
- Various bugfixes, including support for the new GTK 4.14 GL renderer. The plugin needs to be built with at least the
|
||
gtk_v4_10 feature to work with the new GTK 4.14 GL renderer, and will work best if built with the gtk_v4_14 feature.
|
||
|
||
### Closed Caption
|
||
|
||
- Add cea608tocea708 element for upconverting CEA-608 captions to their CEA-708 representation.
|
||
|
||
- Add support for translations within transcriberbin.
|
||
|
||
- awstranscriber supports translating the transcribed text into different languages, including multiple languages at the same
|
||
time.
|
||
|
||
- awstranscriber is using the new HTTP/2-based API now instead of the WebSocket-based one.
|
||
|
||
### Other new elements
|
||
|
||
- New awss3putobjectsink that works similar to awss3sink but with a different upload strategy.
|
||
|
||
- New hlscmafsink element for writing HLS streams with CMAF/ISOBMFF fragments.
|
||
|
||
- New inter plugin with new intersink and intersrc elements that allow to 1:N connect different pipelines in the same process.
|
||
This is implemented around the appsrc / appsink-based StreamProducer API that is provided as part of the GStreamer Rust
|
||
bindings, and is also used inside webrtcsrc and webrtcsink.
|
||
|
||
- New livesync element that allows maintaining a contiguous live stream without gaps from a potentially unstable source.
|
||
|
||
- New isomp4mux non-fragmented MP4 muxer element.
|
||
|
||
### Other improvements
|
||
|
||
- audiornnoise
|
||
- Attach audio level meta to output buffers.
|
||
- Add voice detection threshold property
|
||
- fmp4mux
|
||
- Add support for CMAF-style chunking, e.g. low-latency / LL HLS and DASH
|
||
- Add support for muxing Opus, VP8, VP9 and AV1 streams
|
||
- Add ‘offset-to-zero’ property and make media/track timescales configurable
|
||
- hlssink3
|
||
- Allow adding EXT-X-PROGRAM-DATE-TIME tag to the manifest.
|
||
- Allow generating I-frame-only playlist
|
||
- ndi
|
||
- Closed Caption support in ndisrc / ndisink
|
||
- Zero-copy output support in ndisrc for raw video and audio
|
||
- spotifyaudiosrc: Support configurable bitrate
|
||
|
||
For a full list of changes in the Rust plugins see the gst-plugins-rs ChangeLog between versions 0.9 (shipped with GStreamer
|
||
1.22) and 0.12 (shipped with GStreamer 1.24).
|
||
|
||
## Cerbero Rust support
|
||
|
||
- As of GStreamer 1.24, the GStreamer Rust plugins are shipped as part of our binary packages on all major platforms. This
|
||
includes Android and iOS now in addition to macOS and Windows/MSVC.
|
||
|
||
## Build and Dependencies
|
||
|
||
- Meson >= 1.1 is now required for all modules
|
||
|
||
- The GLib requirement has been bumped to >= 2.64
|
||
|
||
- liborc >= 0.4.38 is strongly recommended
|
||
|
||
- libnice >= 0.1.22 is strongly recommended, as it is required for WebRTC ICE consent freshness (RFC 7675).
|
||
|
||
- gst-libav was updated for FFmpeg API deprecations and removals
|
||
|
||
- libwebpmux is required for the animated WebP support
|
||
|
||
- The wpe plugin gained support for the WPEWebKit 2.0 API version
|
||
|
||
- Bumped minimum libva version to 1.12 for the va plugin.
|
||
|
||
- zxing: added support for the zxing-c++ 2.0 API
|
||
|
||
- The ptp-helper for Precision Time Protocol (PTP) support in GStreamer core has been rewritten in Rust, and the minimum
|
||
required Rust version for building this is 1.48, i.e. the version currently in Debian oldstable. On Windows, at least Rust
|
||
1.54 is needed. There is a new ptp-helper Meson feature option that can be used to make sure everything needed for PTP
|
||
support is available (if set to ptp-helper=enabled). cargo is not required for building.
|
||
|
||
- gst-plugins-rs requires Rust 1.70 or newer.
|
||
|
||
- Link to libsoup at build time in all cases on non-Linux, and only load it dynamically on Linux systems where we might need
|
||
to support a mix of applications with dependencies that might be using libsoup2 or libsoup3. A “soup-version” meson build
|
||
option was added to prefer a specific version. Distros should make sure that libsoup is still a package dependency, since
|
||
it’s still required at runtime for the soup and adaptivedemux2 plugins to function.
|
||
|
||
- libjack is now dynamically loaded at runtime by the JACK audio plugin, and no longer a hard build dependency. However, it
|
||
still is a runtime dependency, so distros should make sure it remains a package dependency.
|
||
|
||
Monorepo build (née gst-build)
|
||
|
||
- There is now a top-level meson build option to enable/require webrtc
|
||
|
||
- The FFmpeg subproject wrap was udpated to 6.1
|
||
|
||
- A libvpx wrap was added (for VP8/VP9 software encoding/decoding)
|
||
|
||
gstreamer-full
|
||
|
||
- Add full static build support, including on Windows: Allow a project to use gstreamer-full as a static library and link to
|
||
create a binary without dependencies. Introduce the meson build option gst-full-target-type to select the build type:
|
||
dynamic (default) or static.
|
||
|
||
- Registers all full features in a plugin now to offer the possibility to get information at the plugin level and get it from
|
||
the registry. All the full features are now registered in a fullstaticfeatures meta plugin instead of having a NULL plugin.
|
||
|
||
Development environment
|
||
|
||
- add VSCode IDE integration
|
||
|
||
- gst-env.py: Output a setting for the prompt with --only-environment
|
||
|
||
### 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.
|
||
|
||

|
||
- New qml6 plugin can be built on Windows with the qt6 variant enabled
|
||
- Similar to qt5, this plugin cannot be included in the official binaries
|
||
- GLib process handling helpers for Windows are now shipped
|
||
- Windows 11 SDK is now required for builds
|
||
- Visual Studio 2019 and newer ship this SDK
|
||
- MSYS is now deprecated for building Windows binaries, will be removed in the next release
|
||
- MSYS2 is required, and the bootstrap script tools/bootstrap-windows.ps can install it for you
|
||
- Windows bootstrap script tools/bootstrap-windows.ps1 is much more interactive and user-friendly now
|
||

|
||
- tremor and ivorbisdec plugins are no longer shipped on Android
|
||
- openh264 plugin no longer enables ASM optimizations on Android x86 due to relocation errors
|
||
|
||
## Platform-specific changes and improvements
|
||
|
||
### Android
|
||
|
||
- Add NDK implementation of Android MediaCodec. This reduces the amount of Java <-> native calls, which should reduce
|
||
overhead.
|
||
|
||
- Add support for AV1 to the androidmedia video encoder and decoder.
|
||
|
||
### Apple macOS and iOS
|
||
|
||
- osxaudio: audio clock improvements (interpolate based on system time)
|
||
|
||
- Set activation policy in gst_macos_main() and in osxvideosink and glimagesink. Setting the policy to
|
||
NSApplicationActivationPolicyAccessory by default makes sure that we can activate windows programmatically or by clicking on
|
||
them. Without that, windows would disappear if you clicked outside them and there would be no way to bring them to front
|
||
again. This change also allows osxvideosink to receive navigation events correctly.
|
||
|
||
### Windows
|
||
|
||
- New DirectWrite text rendering plugin with dwriteclockoverlay, dwritetimeoverlay, dwritetextoverlay, dwritesubtitlemux, and
|
||
dwritesubtitleoverlay elements, including closed caption overlay support in dwritetextoverlay.
|
||
|
||
- PTP clock support is now also available on Windows
|
||
|
||
- qml6d3d11sink is a new Direct3D11 Qt6 QML sink for Windows as an alternative to the existing qml6glsink.
|
||
|
||
- wasapi2 audio plugin:
|
||
|
||
- Added an option to monitor a loopback device’s mute state
|
||
- Allows process loopback capture on Windows 10
|
||
|
||
- win32ipc supports zero-copy rendering now through a shared bufferpool.
|
||
|
||
- Add a Windows-specific plugin loader implementation (gst-plugin-scanner), so plugin loading during registry updates happens
|
||
in an external process on Windows as well.
|
||
|
||
- gst_video_convert_sample() which is often used for thumbnailing gained a D3D11 specific conversion path.
|
||
|
||
- d3d11 plugin:
|
||
|
||
- d3d11mpeg2dec element is promoted to PRIMARY + 1 rank
|
||
- Added d3d11ipcsrc and d3d11ipcsink elements for zero-copy GPU memory sharing between multiple processes.
|
||
- Added HLSL shader pre-compilation (at binary build time) support in MSVC build.
|
||
- d3d11videosink and d3d11convert elements support 3D transform, MSAA (MultiSampling Anti-Aliasing) and anisotropic
|
||
sampling method.
|
||
- Added support for more raw video formats by using compute shader. A list of supported raw video formats can be found in
|
||
the d3d11videosink plugin documentation.
|
||
- Added d3d11overlay element for applications to be able to draw/blend an overlay image on Direct3D11 texture directly.
|
||
|
||
- New Direct3D12 plugin: From a video decoding, conversion, composition, and rendering point of view, this new d3d12 plugin is
|
||
feature-wise near equivalent to the d3d11 plugin. Notable differences between d3d12 and d3d11 are:
|
||
- The GStreamer Direct3D12 integration layer is not exposed as a GStreamer API yet. Thus, other plugins such as amfcodec,
|
||
nvcodec, qsv, and dwrite are not integrated with d3d12 yet.
|
||
- H.264 video encoding support via d3d12h264enc element.
|
||
- Direct3D12 video encoding API requires Windows 11 or DirectX 12 Agility SDK
|
||
- IPC, overlay, and deinterlace elements are not implemented in d3d12
|
||
- Windows Graphics Capture API based screen capturing is not implemented in d3d12
|
||
- In this release, MSVC is the only officially supported toolchain for the d3d12 plugin build.
|
||
- All d3d12 elements are zero ranked for now. Users will need to adjust rank of each d3d12 element via GST_PLUGIN_RANK
|
||
environment or appropriate plugin feature APIs if they want these elements autoplugged.
|
||
|
||
## Documentation improvements
|
||
|
||
- hotdoc has been updated to the latest version, and the theme has also been updated, which should fix various usability
|
||
issues.
|
||
|
||
## Possibly Breaking Changes
|
||
|
||
- gst_plugin_feature_check_version() has been updated to fix unexpected version check behaviour for git versions. It would
|
||
return TRUE if the plugin version is for a git development version (e.g. 1.24.0.1) and the check is for the “next” micro
|
||
version (1.24.1). Now it no longer does this. This just brings the runtime version check in line with the build time version
|
||
checks which have been fixed some time ago.
|
||
|
||
- GstAudioAggregator and subclasses such as audiomixer now sync property values to output timestamp, which is what
|
||
GstVideoAggregator has been doing already since 2019, and which makes sense, as the properties need to change at every
|
||
output frame based on the output time because they may change even though the input frame is not changing.
|
||
|
||
- rtpac3depay now outputs audio/x-ac3 instead of audio/ac3 as that is the canonical media format in GStreamer. audio/ac3 is
|
||
still sometimes accepted as input format for backwards compatibility (e.g. in rtpac3pay or ac3parse), but shouldn’t be
|
||
output.
|
||
|
||
- timecodestamper: The “drop-frame” property now defaults to TRUE
|
||
|
||
- The NVIDIA desktop GPU decoders nvh264sldec, nvh265sldec, nvvp8sldec and nvvp9sldec were renamed to nvh264dec, nvh265dec,
|
||
nvvp8dec and nvvp9dec, respectively.
|
||
|
||
## Known Issues
|
||
|
||
- There are known issues with FFmpeg version 6.0.0 due to opaque passing being broken in that version. This affects at least
|
||
avdec_h264, but may affect other decoders as well. Versions before 6.0.0, and 6.0.1 or higher are not affected.
|
||
|
||
- gst-libav currently doesn’t build against the latest FFmpeg 7.0 release. This is being worked on and tracked in this “libav:
|
||
Fix compatibility with ffmpeg 7” Merge Request.

Schedule for 1.26
|
||
|
||
Our next major feature release will be 1.26, and 1.25 will be the unstable development version leading up to the stable 1.26
|
||
release. The development of 1.25/1.25 will happen in the git main branch of the GStreamer mono repository.
|
||
|

||
|
||
1.26 will be backwards-compatible to the stable 1.24, 1.22, 1.20, 1.18, 1.16, 1.14, 1.12, 1.10, 1.8, 1.6, 1.4, 1.2 and 1.0
