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
-

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.

-
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

-
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.

-
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:
-
Planar 16-bit 4:4:4 RGB formats:
-
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:
-
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
New tracers
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 GstValidateActionParameter s 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 webrtcsink s 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
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
Cerbero
Cerbero is a meta build system used to build GStreamer plus dependencies

- 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

- Windows bootstrap script
tools/bootstrap-windows.ps1 is much more interactive and user-friendly now
- Fixed Pango crash on 32-bit Windows
- WiX packaging now works with cross-windows builds from linux
Linux
- Linux packages will now also include static libs for the GStreamer Rust plugins

- The Android binary packages now include the GStreamer Rust plugins
-
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.
- 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.
The schedule for 1.26 is yet to be decided.
