Version 2.1, February 1999

Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
[This is the first released version of the Lesser GPL. It also counts
as the successor of the GNU Library Public License, version 2, hence
the version number 2.1.]
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
Licenses are intended to guarantee your freedom to share and change
free software--to make sure the software is free for all its users.
This license, the Lesser General Public License, applies to some
specially designated software packages--typically libraries--of the
Free Software Foundation and other authors who decide to use it. You
can use it too, but we suggest you first think carefully about whether
this license or the ordinary General Public License is the better
strategy to use in any particular case, based on the explanations
below.
When we speak of free software, we are referring to freedom of use,
not price. Our General Public Licenses are designed to make sure that
you have the freedom to distribute copies of free software (and charge
for this service if you wish); that you receive source code or can get
it if you want it; that you can change the software and use pieces of
it in new free programs; and that you are informed that you can do
these things.
To protect your rights, we need to make restrictions that forbid
distributors to deny you these rights or to ask you to surrender these
rights. These restrictions translate to certain responsibilities for
you if you distribute copies of the library or if you modify it.
For example, if you distribute copies of the library, whether gratis
or for a fee, you must give the recipients all the rights that we gave
you. You must make sure that they, too, receive or can get the source
code. If you link other code with the library, you must provide
complete object files to the recipients, so that they can relink them
with the library after making changes to the library and recompiling
it. And you must show them these terms so they know their rights.
We protect your rights with a two-step method: (1) we copyright the
library, and (2) we offer you this license, which gives you legal
permission to copy, distribute and/or modify the library.
To protect each distributor, we want to make it very clear that
there is no warranty for the free library. Also, if the library is
modified by someone else and passed on, the recipients should know
that what they have is not the original version, so that the original
author's reputation will not be affected by problems that might be
introduced by others.
Finally, software patents pose a constant threat to the existence of
any free program. We wish to make sure that a company cannot
effectively restrict the users of a free program by obtaining a
restrictive license from a patent holder. Therefore, we insist that
any patent license obtained for a version of the library must be
consistent with the full freedom of use specified in this license.
Most GNU software, including some libraries, is covered by the
ordinary GNU General Public License. This license, the GNU Lesser
General Public License, applies to certain designated libraries, and
is quite different from the ordinary General Public License. We use
this license for certain libraries in order to permit linking those
libraries into non-free programs.
When a program is linked with a library, whether statically or using
a shared library, the combination of the two is legally speaking a
combined work, a derivative of the original library. The ordinary
General Public License therefore permits such linking only if the
entire combination fits its criteria of freedom. The Lesser General
Public License permits more lax criteria for linking other code with
the library.
We call this license the "Lesser" General Public License because it
does Less to protect the user's freedom than the ordinary General
Public License. It also provides other free software developers Less
of an advantage over competing non-free programs. These disadvantages
are the reason we use the ordinary General Public License for many
libraries. However, the Lesser license provides advantages in certain
special circumstances.
For example, on rare occasions, there may be a special need to
encourage the widest possible use of a certain library, so that it
becomes a de-facto standard. To achieve this, non-free programs must
be allowed to use the library. A more frequent case is that a free
library does the same job as widely used non-free libraries. In this
case, there is little to gain by limiting the free library to free
software only, so we use the Lesser General Public License.
In other cases, permission to use a particular library in non-free
programs enables a greater number of people to use a large body of
free software. For example, permission to use the GNU C Library in
non-free programs enables many more people to use the whole GNU
operating system, as well as its variant, the GNU/Linux operating
system.
Although the Lesser General Public License is Less protective of the
users' freedom, it does ensure that the user of a program that is
linked with the Library has the freedom and the wherewithal to run
that program using a modified version of the Library.
The precise terms and conditions for copying, distribution and
modification follow. Pay close attention to the difference between a
"work based on the library" and a "work that uses the library". The
former contains code derived from the library, whereas the latter must
be combined with the library in order to run.
GNU LESSER GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library or other
program which contains a notice placed by the copyright holder or
other authorized party saying it may be distributed under the terms of
this Lesser General Public License (also called "this License").
Each licensee is addressed as "you".
A "library" means a collection of software functions and/or data
prepared so as to be conveniently linked with application programs
(which use some of those functions and data) to form executables.
The "Library", below, refers to any such software library or work
which has been distributed under these terms. A "work based on the
Library" means either the Library or any derivative work under
copyright law: that is to say, a work containing the Library or a
portion of it, either verbatim or with modifications and/or translated
straightforwardly into another language. (Hereinafter, translation is
included without limitation in the term "modification".)
"Source code" for a work means the preferred form of the work for
making modifications to it. For a library, complete source code means
all the source code for all modules it contains, plus any associated
interface definition files, plus the scripts used to control
compilation and installation of the library.
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running a program using the Library is not restricted, and output from
such a program is covered only if its contents constitute a work based
on the Library (independent of the use of the Library in a tool for
writing it). Whether that is true depends on what the Library does
and what the program that uses the Library does.
1. You may copy and distribute verbatim copies of the Library's
complete source code as you receive it, in any medium, provided that
you conspicuously and appropriately publish on each copy an
appropriate copyright notice and disclaimer of warranty; keep intact
all the notices that refer to this License and to the absence of any
warranty; and distribute a copy of this License along with the
Library.
You may charge a fee for the physical act of transferring a copy,
and you may at your option offer warranty protection in exchange for a
fee.
2. You may modify your copy or copies of the Library or any portion
of it, thus forming a work based on the Library, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) The modified work must itself be a software library.
b) You must cause the files modified to carry prominent notices
stating that you changed the files and the date of any change.
c) You must cause the whole of the work to be licensed at no
charge to all third parties under the terms of this License.
d) If a facility in the modified Library refers to a function or a
table of data to be supplied by an application program that uses
the facility, other than as an argument passed when the facility
is invoked, then you must make a good faith effort to ensure that,
in the event an application does not supply such function or
table, the facility still operates, and performs whatever part of
its purpose remains meaningful.
(For example, a function in a library to compute square roots has
a purpose that is entirely well-defined independent of the
application. Therefore, Subsection 2d requires that any
application-supplied function or table used by this function must
be optional: if the application does not supply it, the square
root function must still compute square roots.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Library,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Library, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote
it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Library.
In addition, mere aggregation of another work not based on the Library
with the Library (or with a work based on the Library) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may opt to apply the terms of the ordinary GNU General Public
License instead of this License to a given copy of the Library. To do
this, you must alter all the notices that refer to this License, so
that they refer to the ordinary GNU General Public License, version 2,
instead of to this License. (If a newer version than version 2 of the
ordinary GNU General Public License has appeared, then you can specify
that version instead if you wish.) Do not make any other change in
these notices.
Once this change is made in a given copy, it is irreversible for
that copy, so the ordinary GNU General Public License applies to all
subsequent copies and derivative works made from that copy.
This option is useful when you wish to copy part of the code of
the Library into a program that is not a library.
4. You may copy and distribute the Library (or a portion or
derivative of it, under Section 2) in object code or executable form
under the terms of Sections 1 and 2 above provided that you accompany
it with the complete corresponding machine-readable source code, which
must be distributed under the terms of Sections 1 and 2 above on a
medium customarily used for software interchange.
If distribution of object code is made by offering access to copy
from a designated place, then offering equivalent access to copy the
source code from the same place satisfies the requirement to
distribute the source code, even though third parties are not
compelled to copy the source along with the object code.
5. A program that contains no derivative of any portion of the
Library, but is designed to work with the Library by being compiled or
linked with it, is called a "work that uses the Library". Such a
work, in isolation, is not a derivative work of the Library, and
therefore falls outside the scope of this License.
However, linking a "work that uses the Library" with the Library
creates an executable that is a derivative of the Library (because it
contains portions of the Library), rather than a "work that uses the
library". The executable is therefore covered by this License.
Section 6 states terms for distribution of such executables.
When a "work that uses the Library" uses material from a header file
that is part of the Library, the object code for the work may be a
derivative work of the Library even though the source code is not.
Whether this is true is especially significant if the work can be
linked without the Library, or if the work is itself a library. The
threshold for this to be true is not precisely defined by law.
If such an object file uses only numerical parameters, data
structure layouts and accessors, and small macros and small inline
functions (ten lines or less in length), then the use of the object
file is unrestricted, regardless of whether it is legally a derivative
work. (Executables containing this object code plus portions of the
Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may
distribute the object code for the work under the terms of Section 6.
Any executables containing that work also fall under Section 6,
whether or not they are linked directly with the Library itself.
6. As an exception to the Sections above, you may also combine or
link a "work that uses the Library" with the Library to produce a
work containing portions of the Library, and distribute that work
under terms of your choice, provided that the terms permit
modification of the work for the customer's own use and reverse
engineering for debugging such modifications.
You must give prominent notice with each copy of the work that the
Library is used in it and that the Library and its use are covered by
this License. You must supply a copy of this License. If the work
during execution displays copyright notices, you must include the
copyright notice for the Library among them, as well as a reference
directing the user to the copy of this License. Also, you must do one
of these things:
a) Accompany the work with the complete corresponding
machine-readable source code for the Library including whatever
changes were used in the work (which must be distributed under
Sections 1 and 2 above); and, if the work is an executable linked
with the Library, with the complete machine-readable "work that
uses the Library", as object code and/or source code, so that the
user can modify the Library and then relink to produce a modified
executable containing the modified Library. (It is understood
that the user who changes the contents of definitions files in the
Library will not necessarily be able to recompile the application
to use the modified definitions.)
b) Use a suitable shared library mechanism for linking with the
Library. A suitable mechanism is one that (1) uses at run time a
copy of the library already present on the user's computer system,
rather than copying library functions into the executable, and (2)
will operate properly with a modified version of the library, if
the user installs one, as long as the modified version is
interface-compatible with the version that the work was made with.
c) Accompany the work with a written offer, valid for at least
three years, to give the same user the materials specified in
Subsection 6a, above, for a charge no more than the cost of
performing this distribution.
d) If distribution of the work is made by offering access to copy
from a designated place, offer equivalent access to copy the above
specified materials from the same place.
e) Verify that the user has already received a copy of these
materials or that you have already sent this user a copy.
For an executable, the required form of the "work that uses the
Library" must include any data and utility programs needed for
reproducing the executable from it. However, as a special exception,
the materials to be distributed need not include anything that is
normally distributed (in either source or binary form) with the major
components (compiler, kernel, and so on) of the operating system on
which the executable runs, unless that component itself accompanies
the executable.
It may happen that this requirement contradicts the license
restrictions of other proprietary libraries that do not normally
accompany the operating system. Such a contradiction means you cannot
use both them and the Library together in an executable that you
distribute.
7. You may place library facilities that are a work based on the
Library side-by-side in a single library together with other library
facilities not covered by this License, and distribute such a combined
library, provided that the separate distribution of the work based on
the Library and of the other library facilities is otherwise
permitted, and provided that you do these two things:
a) Accompany the combined library with a copy of the same work
based on the Library, uncombined with any other library
facilities. This must be distributed under the terms of the
Sections above.
b) Give prominent notice with the combined library of the fact
that part of it is a work based on the Library, and explaining
where to find the accompanying uncombined form of the same work.
8. You may not copy, modify, sublicense, link with, or distribute
the Library except as expressly provided under this License. Any
attempt otherwise to copy, modify, sublicense, link with, or
distribute the Library is void, and will automatically terminate your
rights under this License. However, parties who have received copies,
or rights, from you under this License will not have their licenses
terminated so long as such parties remain in full compliance.
9. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Library or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Library (or any work based on the
Library), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Library or works based on it.
10. Each time you redistribute the Library (or any work based on the
Library), the recipient automatically receives a license from the
original licensor to copy, distribute, link with or modify the Library
subject to these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties with
this License.
11. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Library at all. For example, if a patent
license would not permit royalty-free redistribution of the Library by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Library.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply, and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
12. If the distribution and/or use of the Library is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Library under this License
may add an explicit geographical distribution limitation excluding those
countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
13. The Free Software Foundation may publish revised and/or new
versions of the Lesser General Public License from time to time.
Such new versions will be similar in spirit to the present version,
but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Library
specifies a version number of this License which applies to it and
"any later version", you have the option of following the terms and
conditions either of that version or of any later version published by
the Free Software Foundation. If the Library does not specify a
license version number, you may choose any version ever published by
the Free Software Foundation.
14. If you wish to incorporate parts of the Library into other free
programs whose distribution conditions are incompatible with these,
write to the author to ask for permission. For software which is
copyrighted by the Free Software Foundation, write to the Free
Software Foundation; we sometimes make exceptions for this. Our
decision will be guided by the two goals of preserving the free status
of all derivatives of our free software and of promoting the sharing
and reuse of software generally.
NO WARRANTY
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Libraries
If you develop a new library, and you want it to be of the greatest
possible use to the public, we recommend making it free software that
everyone can redistribute and change. You can do so by permitting
redistribution under these terms (or, alternatively, under the terms
of the ordinary General Public License).
To apply these terms, attach the following notices to the library.
It is safest to attach them to the start of each source file to most
effectively convey the exclusion of warranty; and each file should
have at least the "copyright" line and a pointer to where the full
notice is found.
<one line to give the library's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This library is free software; you can redistribute it and/or
modify it under the terms of the GNU Lesser General Public
License as published by the Free Software Foundation; either
version 2.1 of the License, or (at your option) any later version.
This library is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU

You should have received a copy of the GNU Lesser General Public
License along with this library; if not, write to the Free Software
Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Also add information on how to contact you by electronic and paper mail.
You should also get your employer (if you work as a programmer) or
your school, if any, to sign a "copyright disclaimer" for the library,
if necessary. Here is a sample; alter the names:

## Major new features and changes
### H.266 Versatile Video Coding (VVC) codec support
- The H.266 / VVC video codec is a successor to H.265 / HEVC and is standardised in ISO/IEC 23090-3.
- A new h266parse element was added, along with parsing API, typefinding support and some codec utility functions in the
gst-plugins-base utility library.
- A H.266 decoder base class for hardware-accelerated decoders was added and used to implement a VA-API-based
hardware-accelerated H.266 decoder.
- The FFmpeg H.266 decoder is exposed now (from FFmpeg 7.0 onwards).
- H.266 / VVC muxing and demuxing support was implemented for MP4, Matroska and MPEG-TS containers.
- A VVdeC-based H.266 decoder element was added to the Rust plugins, based on the Fraunhofer Versatile Video Decoder library.
### JPEG XS image codec support
- JPEG XS is a visually lossless, low-latency, intra-only video codec for video production workflows, standardised in ISO/IEC
21122.
- JPEG XS encoder and decoder elements based on the SVT JPEG XS library were added, including support for muxing JPEG XS into
MPEG-TS and demuxing it. Both interlaced and progressive modes are supported.
### Low Complexity Enhancement Video Coding (LCEVC) support
- LCEVC is a codec that provides an enhancement layer on top of another codec such as H.264 for example. It is standardised as
MPEG-5 Part 2.
- LCEVC encoder and decoder elements based on V-Nova’s SDK libraries were added, including support in h264parse for extracting
the enhancement layer from H.264 and decoding it via a lcevch264decodebin element.
### Closed captions improvements
- New H.264 and H.265 closed captions extractor and inserter elements.
- These extractor elements don’t actually extract captions from the bitstream, but rely on parser elements to do that and
add them to buffers in form of caption metas. The problem is that streams might contain B-frames, in which case the
captions in the bitstream will not be in presentation order and extracting them requires frame-reordering in the same
way that a decoder would do. These new elements will do exactly that and allow you to extract captions in presentation
order without having to decode the stream.
- The inserter elements do something similar and insert caption SEIs into the H.264 or H.265 bitstream, taking into
account frame ordering.
- This is useful if one wants to extract, process and re-insert captions into an existing video bitstream without decoding
and re-encoding it (in which case the decoder and encoder would handle the caption reordering).
- cdpserviceinject: New element for injecting a CDP service descriptor into closed caption CDP packets
- cea708overlay: New element for overlaying CEA608 / CEA708 closed captions over video streams.
- The cc708overlay element has been deprecated in favour of the cea708overlay element from the Rust plugins set.
- cea608mux gained a "force-live" property to make it always in live mode and aggregate on timeout regardless of whether any
live sources are linked upstream.
- cea708mux: New element that allows to mux multiple CEA708 services into a single stream.
- cccombiner has two new properties:
- "input-meta-processing" controls how input closed caption metas are processed and can be used to e.g. discard closed
captions from the input pad if the matching video buffer already has closed caption on it.
- "schedule-timeout" to support timing out captions without EOS
- tttocea708: New element for converting timed-text to CEA708 closed captions
- Miscellaneous improvements and spec compliance fixes
### Speech to Text, Translation and Speech Synthesis
- awstranscriber2, awstranslate: New elements around the AWS transcription and translation services.
- polly: New element around the AWS text-to-speech polly services
- speechmatics: New transcriber / speech-to-text and translation element
- translationbin: Helper bin around translation elements, similar to the already existing transcriberbin for transcriptions.
### HLS DASH adaptive streaming improvements
- The adaptivedemux2 client implementation gained support for file:// URIs and as such the ability to play HLS and DASH from
local files. It also no longer sends spurious flush events when it loses sync in live streams, as that is unexpected and
will be handled poorly in non-playback scenarios. Lastly, support for HTTP request retries was added via the "max-retries"
property, along with some exponential backoff logic which can be fine-tuned via properties.
- dashsink has received period duration fixes for dynamic MPDs and some memory leak fixes.
- hlscmafsink, hlssink3: New single-variant HLS sink elements that can output CMAF (fMP4) or MPEG-TS fragments.
- hlsmultivariantsink: New sink element that can output an HLS stream with multiple variants
### splitmuxsrc, splitmuxsink: lazy loading and dynamic fragment addition
- splitmuxsrc and splitmuxsink were originally designed to handle a small number of large file fragments, e.g. for situations
where one doesn’t want to exceed a certain file size when recording to legacy file systems. It was also designed for playing
back a static set of file fragments that have been created by an earlier recording session and no longer changes. Over time
people have found more applications and use cases for the splitmux elements and have been deploying them in different
scenarios, exposing the limits of the current implementation.
- In this release, splitmuxsink and splitmuxsrc gained new abilities aimed at improving support for recordings with a large
number of files, and for adding fragments on the fly to allow playback of ongoing recordings:
- You can now add fragments directly to splitmuxsrc and provide the offset and duration in the stream:
- Providing offset and duration means splitmuxsrc doesn’t need to scan the file to measure it and calculate it. That
makes for much faster startup.
- The new "add-fragment" signal can be used to add files to the set dynamically - allowing to be playing an ongoing
recording and adding files to the playback set as they are finished.
- splitmuxsrc no longer keeps all files open, but instead only keeps 100 files open by default, configurable with the
"num-open-fragments" property.
- There is a new "num-lookahead" property on splitmuxsrc to trigger (re)opening files a certain distance ahead of the play
position.
- splitmuxsink will report fragment offset and fragment duration via a message on the bus when closing a file. This
information can then be used to add the new fragment to a splitmuxsrc.
### MPEG-TS container format improvements
- The MPEG-TS muxer and demuxer gained support for
- H.266 / VVC video muxing and demuxing
- JPEG-XS video muxing and demuxing
- VP9 video muxing and demuxing (using a custom mapping)
- AV1 video muxing and demuxing (using a custom mapping, since the work-in-progress specification effort doesn’t seem to
be going anywhere anytime soon)
- SMPTE ST-2038 ancillary metadata streams (see section above)
- mpegtsmux gained support for muxing ID3 metadata into the TS stream, as well as SMPTE 302M audio.
- It’s also possible to disable sending SCTE-35 null (heartbeat) packets now in mpegtsmux by setting the
"scte-35-null-interval" to 0.
- tsparse now handles 192-byte M2TS packets
- mpegtslivesrc: New source element that can wrap a live MPEG-TS source (e.g. SRT or UDP source) and provides a clock based on
the PCR.
### Matroska container format improvements
- H.266 / VVC video muxing and demuxing support
- matroskamux
- was ported to the GstAggregator base class, ensuring defined-latency muxing in live streaming pipelines.
- gained rotation tag support
- matroskademux now also supports seeks with a stop position in push mode.
### ISO MP4 container format improvements
- can mux and demux H.266 / VVC in MP4 now
- can demux Hap video now, as well as Lagarith lossless video and ISO/IEC 23003-5 raw PCM audio.
- qtdemux handles keyunit-only trick mode also in push mode now
- support for ISO/IEC 23001-17 raw video in MP4 in qtdemux and isomp4mux.
- support for rotation tags in the muxers and demuxers was improved to correctly handle per-media and per-track rotations, and
support for flips was added as well.
SMPTE 2038 ancillary data streams
- SMPTE 2038 (pdf) is a generic system to put VBI-style ancillary data into an MPEG-TS container. This could include all kinds
of metadata such as scoreboard data or game clocks, and of course also closed captions, in this case in form of a distinct
stream completely separate from any video bitstream.
- A number of new elements in the GStreamer Rust closedcaption plugin add support for this, along with mappings for it in the
MPEG-TS muxer and demuxer. The new elements are:
- st2038ancdemux: splits SMPTE ST-2038 ancillary metadata (as received from tsdemux) into separate streams per DID/SDID
and line/horizontal_offset. Will add a sometimes pad with details for each ancillary stream. Also has an always source
pad that just outputs all ancillary streams for easy forwarding or remuxing, in case none of the ancillary streams need
to be modified or dropped.
- st2038ancmux: muxes SMPTE ST-2038 ancillary metadata streams into a single stream for muxing into MPEG-TS with
mpegtsmux. Combines ancillary data on the same line if needed, as is required for MPEG-TS muxing. Can accept individual
ancillary metadata streams as inputs and/or the combined stream from st2038ancdemux.
If the video framerate is known, it can be signalled to the ancillary data muxer via the output caps by adding a
capsfilter behind it, with e.g. meta/x-st-2038,framerate=30/1.
This allows the muxer to bundle all packets belonging to the same frame (with the same timestamp), but that is not
required. In case there are multiple streams with the same DID/SDID that have an ST-2038 packet for the same frame, it
will prioritise the one from more recently created request pads over those from earlier created request pads (which
might contain a combined stream for example if that’s fed first).
- st2038anctocc: extracts closed captions (CEA-608 and/or CEA-708) from SMPTE ST-2038 ancillary metadata streams and
outputs them on the respective sometimes source pad (src_cea608 or src_cea708). The data is output as a closed caption
stream with caps closedcaption/x-cea-608,format=s334-1a or closedcaption/x-cea-708,format=cdp for further processing by
other GStreamer closed caption processing elements.
- cctost2038anc: takes closed captions (CEA-608 and/or CEA-708) as produced by other GStreamer closed caption processing
elements and converts them into SMPTE ST-2038 ancillary data that can be fed to st2038ancmux and then to mpegtsmux for
splicing/muxing into an MPEG-TS container. The line-number and horizontal-offset properties should be set to the desired
line number and horizontal offset.
### Analytics
- Added a GstTensorMeta: This meta is designed to carry tensors from the inference element to the model-specific tensor
decoder. This also includes a basic GstTensor class containing a single tensor. The actual tensor data is a GstBuffer.
- Add N_TO_N relationship to GstAnalyticsRelationMeta: This makes it possible to describe N-to-N relationships. For example,
between classes and regions in an instance segmentation.
- Add a new analytics Mtd to carry segmentation masks: Being part of the GstAnalyticsMeta, it can be in relationship with the
other Mtd, such as the classification and object detection bounding boxes.
- onvifmetadataextractor: New element that can extract ONVIF metadata from GstMetas into a separate stream
- originalbuffer: New plugin with originalbuffersave / originalbufferrestore elements that allow saving an original buffer,
modifying it for analytics, and then restoring the original buffer content while keeping any additional metadata that was
added.
- relationmeta: New plugin with elements converting between GstRelationMeta and ONVIF XML metadata.
- Improved Python bindings for a more Pythonic interface when iterating over GstRelationMeta’s mtd

- gldownload can import DMABufs from a downstream pool
- glupload gained a DRM raw uploader
### Qt5 + Qt6 QML integration improvements
- qmlglsink, qml6glsink now support external-oes textures, which allows direct DMABuf import from hardware decoders. Both also
support NV12 as an input format now.
- qmlglsink gained support for RGB16/BGR16 as input format
- qmlgl6src can now use a downstream buffer pool when available
- qmlgloverlay make the depth/stencil buffer optional, which reduces memory bandwidth on Windows.
### CUDA / NVCODEC integration and feature additions
- Added AV1 video encoder nvav1enc
- CUDA mode nvcuda{CODEC}enc encode elements are renamed to nv{CODEC}enc and old nv{CODEC}enc implementations are removed
- Added support for CUDA Stream-Ordered allocator
- Added cudacompositor element which is equivalent to the software compositor element but uses CUDA
- Added support for CUDA kernel precompile at plugin build time using nvcc and NVCODEC plugin can cache/reuse compiled CUDA
CUBIN/PTX
- cudaupload and cudadownload elements can support Jetson platform’s NVMM memory in addition to already supported desktop NVMM
memory
- Introduced nvdswrapper plugin which uses NVIDIA DeepStream SDK APIs with gst-cuda in an integrated way:
- nvdsdewarp: NVIDIA NVWarp360 API based dewarping element
### GStreamer Direct3D12 integration
- New gst-d3d12 public library. The following elements are integrated with the gst-d3d12 library:
- NVIDIA NVCODEC decoders and encoders can support D3D12 memory
- Intel QSV encoders can accept D3D12 memory
- All elements in dwrite plugin can support D3D12 memory
- The d3d12 library and plugin can be built with MinGW toolchain now (in addition to MSVC)
- D3D12 video decoders and d3d12videosink are promoted to have higher rank than D3D11 elements
- Added support for multiple mip-levels D3D12 textures:
- Newly added d3d12mipmapping element can generate D3D12 textures with multiple mip-levels
- max-mip-levels property is added to d3d12convert, d3d12videosink, and d3d12swapchainsink element, so that the elements
can generate an intermediate texture with multiple mip-levels in order to reduce downscale aliasing artifacts
- d3d12convert, d3d12videosink, and d3d12swapchainsink support the GstColorBalanceInterface to offer color balancing functions
such as hue, saturation, and brightness adjustment
- Added d3d12ipcsink and d3d12ipcsrc elements for zero-copy GPU memory sharing between processes
- d3d12upload and d3d12download support direct GPU memory copy between D3D12 and D3D12 resources
- Added d3d12swapchainsink element to support DirectComposition or UWP/WinUI3 SwapChainPanel based applications

- The Blackmagic Decklink plugin gained support
- for HDR output and input (PQ + HLG static metadata)
- all modes of Quad HDMI recorder
- scheduling frames before they need to be displayed in decklinkvideosink
### RTP and RTSP stack improvements
- rtspsrc now supports client-managed MIKEY key management. Some RTSP servers (e.g. Axis cameras) expect the client to propose
the encryption key(s) to be used for SRTP / SRTCP. This is required to allow re-keying. This mode can be enabled by enabling
the "client-managed-mikey-mode" property and comes with a number of new signals ("request-rtp-key" and "request-rtcp-key"),
action signals ("set-mikey-parameter" and "remove-key") and properties ("hard-limit" and "soft-limit").
- rtpbin: Add new “never” and “ntp” RTCP sync modes
- Never is useful for some RTSP servers that report plain garbage both via RTCP SR and RTP-Info, for example.
- NTP is useful if synchronization should only ever happen based on RTCP SR or NTP-64 RTP header extensions.
This is part of a bigger refactoring of the synchronization / offsetting code in rtpbin, which also makes it regularly emit
the sync signal even if no new synchronisation information is available, controlled by the new "min-sync-interval" property.
- rtpjitterbuffer: add RFC7273 active status to jitterbuffer stats so applications can easily check whether RFC7273 sync is
active.
- rtph265depay: Add "wait-for-keyframe" "request-keyframe" properties and improve request keyframe logic
- rtppassthroughpay gained the ability to regenerate RTP timestamps from buffer timestamps via the new "retimestamp-mode"
property. This is useful in a relay RTSP server if one wants to do full drift compensation and ensure that the stream coming
out of gst-rtsp-server is not drifting compared to the pipeline clock and also not compared to the RTCP NTP times.
- New Rust RTP payloaders and depayloaders for AC3, AMR, JPEG, KLV, MPEG-TS (MP2T), MPEG-4 (MP4A, MP4G), Opus, PCMU (uLaw),
PCMA (aLaw), VP8, VP9.
- New rtpbin2 based on separate rtprecv and rtpsend elements
### WebRTC improvements
- webrtcbin improvements
- Make basic rollbacks work
- Add "reuse-source-pads" property: When set to FALSE, if a transceiver becomes send-only or inactive then pre-existing
source pads will receive an EOS event and no further traffic even after further renegotiation. When TRUE, pads will
simply not receive any output when the negotiated transceiver state doesn’t have incoming traffic. If renegotiated
later, the pad will receive data again.
- Early CNAME support (RFC5576): Have CNAME available to the jitterbuffer before the the first RTCP SR is received, for
rapid synchronization.
- New "post-rtp-aux-sender" signal to allow for placement of an object after rtpbin, before sendbin. This is useful for
objects such as congestion control elements, that don’t want to be burdened by the synchronization requirements of
rtpsession.
- Create and associate transceivers earlier in negotiation, and other spec compliance improvements
- Statistics generation improvements for bundled streams
- webrtcsink improvements:
- Support for more encoders: nvv4l2av1enc, vpuenc_h264 (for imx8mp), nvav1enc, av1enc, rav1enc and nvh265enc.
- The new "define-encoder-bitrates" signal allows applications to fine-tune the bitrate allocation for individual streams
in cases where there are multiple encoders. By default the bitrate is split equally between encoders.
- A generic mechanism was implemented to forward metas over the control channel.
- Added a mechanism for SDP munging to handle server-specific quirks.
- Can expose a built-in web server and signalling server for prototyping and debugging purposes.
- webrtcsink and webrtcsrc enhancements:
- Support for raw payloads, i.e. uncompressed audio and video
- NTP & PTP clock signalling and synchronization support (RFC 7273)
- Generic data channel control mechanism for sending upstream events back to the sender (webrtcsink)
- webrtcsrc now has support for multiple producers
## New elements and plugins
- Many exciting new Rust elements, see Rust section below.
- webview2src: new Microsoft WebView2 based web browser source element
- h264ccextractor, h264ccinserter: H.264 closed caption extractor / inserter
- h265ccextractor, h265ccinserter: H.265 closed caption extractor / inserter
- h266parse
- lcevch264decodebin
- New VA elements (see below): vah266dec, vavp8enc, vajpegenc, vavp8alphadecodebin, vavp9alphadecodebin
- svtjpegxsdec, svtjpegxsenc: SVT JPEG XS decoder/encoder
- Many other new elements mentioned in other sections (e.g. CUDA, NVCODEC, etc.)
## New element features and additions
- audioconvert enhancements:
- Add possibility to reorder input channels when audioconvert has unpositionned audio channels as input. It can now use
reordering configurations to automatically position those channels via the new "input-channels-reorder" and
"input-channels-reorder-mode" properties.
- Better handling of setting of the mix matrix at run time
- handles new GstRequestMixMatrix custom upstream event
- audiorate: Take the tolerance into account when filling gaps; better accounting of the number of samples added or dropped.
- av1enc: Add "timebase" property to allow configuring a specific time base, in line with what exists for vp8enc and vp9enc
already.
- av1parse can parse annexb streams now, and typefinding support has been added for annexb streams as well.
- The GTK3 plugin has gained support for OpenGL/WGL on Windows
- fdsrc has a new "is-live" property to make it act like a live source and timestamp the received data with the clock running
time.
- imagefreeze: Add support for JPEG and PNG
- kmssink: Extended the functionality to support buffers with DRM formats along with non-linear buffers
- pitch now supports reverse playback
- queue can emit the notify signal on queue level changes if the "notify-levels" property has been set.
- qroverlay: the "pixel-size" property has been removed in favour of a new "size" property with slightly different semantics,
where the size of the square is expressed in percent of the smallest of width and height.
- rsvgdec: Negotiate resolution with downstream and scale accordingly
- rtmp2: server authentication improvements
- Mimic librtmp’s behaviour and support additional connection parameters for the connect packet, which are commonly used
for authentication, via the new "extra-connect-args" property.
- Add support for Limelight CDN (llnw) authentication
- scaletempo has gained support for a “fit-down” mode: In fit-down mode only 1.0 rates are supported, and the element will fit
audio data in buffers to their advertised duration. This is useful in speech synthesis cases, where elements such as
awspolly will generate audio data from text, and assign the duration of the input text buffers to their output buffers.
Translated or synthesised audio might be longer than the original inputs, so this makes sure the audio will be sped up to
fit the original duration, so it doesn’t go out of sync.
- souphttpsrc: Add the notion of "retry-backoff" and retry on 503 (service unavailable) and 500 (internal server error) http
errors.
- taginject now modifies existing tag events of the selected scope, with the new "merge-mode" property allowing finer control.
- timecodestamper gained a new running-time source mode that converts the buffer running time into timecodes.
- playbin3, uridecodebin3, parsebin
- lots of stream-collection handling and stability/reliability fixes
- error/warning/info message now include the URI (if known) and stream-id
- missing plugin messages include the stream-id
- videocodectestsink gained support for GBR_10LE, GRAY8 and GRAY10_LE{16,32} pixel formats
- videoflip gained support for the Y444_16LE and Y444_16BE pixel formats
- videoconvertscale:
- Handle pixel aspect ratios with large numerators or denominators
- Explicitly handle the overlaycomposition meta caps feature, so it doesn’t get dropped unnecessarily
- waylandsink prefers DMABuf over system memory now
- x264enc has a new "nal-hrd" property to make the encoder signal HRD information, which is required for Blu-ray streams,
television broadcast and a few other specialist areas. It can also be used to force true CBR, and will cause the encoder to
output null padding packets.
- zbar: add support for binary mode and getting symbols as raw bytes instead of a text string.
## Plugin and library moves
- macOS: atdec was moved from the applemedia plugin in -bad to the osxaudio plugin in -good, in order to be able to share
audio-related helper methods.
## Plugin and element removals
- None in this cycle
## Miscellaneous API additions
### GStreamer Core
- gst_meta_api_type_set_params_aggregator() allows setting an GstAllocationMetaParamsAggregator function for metas, which has
been implemented for GstVideoMeta and is used to aggregate alignment requirements of multiple tee branches.
- gst_debug_print_object() and gst_debug_print_segment() have been made public API. The can be used to easily get string
representations of various types of (mini)objects in custom log handlers.
- Added gst_aggregator_push_src_event(), so subclasses don’t just push events directly onto the source pad bypassing the base
class without giving it the chance to send out any pending serialised events that should be sent out before.
- GstMessage has gained APIs to generically add “details” to messages:
- gst_message_set_details()
- gst_message_get_details()
- gst_message_writable_details()
- gst_message_parse_error_writable_details()
- gst_message_parse_warning_writable_details()
- gst_message_parse_info_writable_details() This is used in uridecodebin3 to add the triggering URI to any INFO, WARNING
or ERROR messages posted on the bus, and in decodebin3 to add the stream ID to any missing plugin messages posted on the
bus.
- gst_util_floor_log2() returns smallest integral value not bigger than log2(v).
- gst_util_fraction_multiply_int64() is a 64-bit variant of gst_util_fraction_multiply().
#### GstIdStr replaces GQuark in structure and caps APIs
- GQuarks are integer identifiers for strings that are inserted into a global hash table, allowing in theory for cheap
equality comparisons. In GStreamer they have been used to represent GstStructure names and field names. The problem is that
these strings once added to the global string table can never be freed again, which can lead to ever-increasing memory usage
for processes where such name identifiers are created based on external input or on locally-created random identifiers.
- GstIdStr is a new data structure made to replace quarks in our APIs. It can hold a short string inline, a static string, or
a reference to a heap-allocated longer string, and allows for cheap storage of short strings and cheap comparisons. It does
not involve access to a global hash table protected by a global lock, and as most strings used in GStreamer structures are
very short, it is actually more performant than quarks in many scenarios.
- GQuark-using APIs in GstStructure or GstCaps have been deprecated and equivalent APIs using GstIdStr have been added
instead. For more details about this change watch Sebastian’s GStreamer Conference presentation “GQuark in GStreamer
structures - what nonsense!”.
- Most applications and plugins will have been using the plain string-based APIs which are not affected by this change.
#### GstVecDeque
- Moved GstQueueArray as GstVecDeque into core for use in GstBus, the ringbuffer logger and in GstBufferPool, where an overly
complicated signaling mechanism using GstAtomicQueue and GstPoll was replaced with GstVecDeque and a simple mutex/cond.
- GstQueueArray in libgstbase was deprecated in favour of GstVecDeque.
- GstAtomicQueue will be deprecated once all users in GStreamer have been moved over to GstVecDeque.
### Audio Library
- Added gst_audio_reorder_channels_with_reorder_map() which allows reordering the samples with a pre-calculated reorder map
instead of re-calculating the reorder map every time.
- Add top-surround-left and top-surround-right channel positions
- GstAudioConverter now supports more numerical types for the mix matrix, namely double, int, int64, uint, and uint64 in
addition to plain floats.
### Plugins Base Utils Library
- New AV1 caps utility functions for AV1 Codec Configuration Record codec_data handling
- The GstEncodingProfile (de)serialization functions are now public
- GstEncodingProfile gained a way to specify a factory-name when specifying caps. In some cases you want to ensure that a
specific element factory is used while requiring some specific caps, but this was not possible so far. You can now do
e.g. qtmux:video/x-prores,variant=standard|factory-name=avenc_prores_ks to ensure that the avenc_prores_ks factory is used
to produce the variant of prores video stream.
### Tag Library
- EXIF handling now support the CAPTURING_LIGHT_SOURCE tag
- Vorbis tag handling gained support for the LYRICS tag
### Video Library and OpenGL Library
- gst_video_convert_sample(), gst_video_convert_sample_async() gained support for D3D12 conversion.
- GstVideoEncoder: gst_video_encoder_release_frame() and gst_video_encoder_drop_frame() have been made available as public
API.
- Navigation: gained mouse double click event support
- Video element QoS handling was improved so as to not overshoot the QoS earliest time by a factor of 2. This was fixed in the
video decoder, encoder, aggregator and audiovisualizer base classes, as well as in the adaptivedemux, deinterlace,
monoscope, shapewipe, and (old) videomixer elements.
- GstVideoConverter gained fast paths for v210 to/from I420_10 / I422_10
- New gst_video_dma_drm_format_from_gst_format() helper function that converts a video format into a dma drm fourcc / modifier
pair, plus gst_video_dma_drm_format_to_gst_format() which will do the reverse.
- In the same vein gst_gl_dma_buf_transform_gst_formats_to_drm_formats() and
gst_gl_dma_buf_transform_drm_formats_to_gst_formats() have been added to the GStreamer OpenGL support library.
- GLDisplay/EGL: Add API (gst_gl_display_egl_set_foreign()) for overriding foreign-ness of the EGLDisplay in order to control
whether GStreamer should call eglTerminate() or not.
- Additional DMA DRM format definitions/mappings:
- NV15, NV20, NV30
- NV12_16L32S, MT2110T, MT2110R as used on Meditek SoCs
- NV12_10LE40
- RGB15, GRAY8, GRAY16_LE, GRAY16_BE
- plus support for big endian DRM formats and DRM vendor modifiers
New Raw Video Formats
- Packed 4:2:2 YUV with 16 bits per channel:
- Y216_LE, Y216_BE
- Packed 4:4:4:4 YUV with alpha, with 16 bits per channel:
- Y416_LE, Y416_BE
- 10-bit grayscale, packed into 16-bit words with left padding:
- GRAY10_LE16
### GstPlay Library
- Add stream-id based selection of streams to better match playbin3’s API:
- Add accessors for the stream ID and selection API based on the stream ID:
- gst_play_stream_info_get_stream_id()
- gst_play_set_audio_track_id()
- gst_play_set_video_track_id()
- gst_play_set_subtitle_track_id()
- gst_play_set_track_ids()
- Deprecate the old index-based APIs:
- gst_play_stream_info_get_index()
- gst_play_set_audio_track()
- gst_play_set_video_track()
- gst_play_set_subtitle_track()
- Remove old playbin support
- Implement the track enable API based on stream selection
- Distinguish missing plugin errors and include more details (uri, and stream-id if available) in error/warning messages:
- gst_play_message_get_uri()
- gst_play_message_get_stream_id()
- GST_PLAY_ERROR_MISSING_PLUGIN
- gst_play_message_parse_error_missing_plugin()
- gst_play_message_parse_warning_missing_plugin()
- Improve play message API inconsistencies:
- Consistently name parse functions according to their message type:
- gst_play_message_parse_duration_changed()
- gst_play_message_parse_buffering()
- Deprecate the misnamed functions:
- gst_play_message_parse_duration_updated()
- gst_play_message_parse_buffering_percent()
- Add missing parse functions:
- gst_play_message_parse_uri_loaded()
- gst_play_message_parse_seek_done()
- Support disabling the selected track at startup
## Miscellaneous performance, latency and memory optimisations
- dvdspu: use multiple minimal sized PGS overlay rectangles instead of a single large one to minimise the total blitting
surface in case of disjointed rectangles.
- video-frame: reduce number of memcpy() calls on frame copies if possible
- video-converter: added fast path conversions between v210 and I420_10 / I422_10
- As always there have been plenty of performance, latency and memory optimisations all over the place.
## Miscellaneous other changes and enhancements
- netclientclock: now also emits the clock synced signal when corrupted to signal that sync has been lost.
- GstValue, GstStructure: can now (de)serialize string arrays (G_TYPE_STRV)
## Tracing framework and debugging improvements
- dot files (pipeline graph dumps) are now written to disk atomically
- tracing: add hooks for gst_pad_send_event_unchecked() and GstMemory init/free
- tracers: Simplify params handling using GstStructure and object properties and move tracers over to property-based
configuration (leaks, latency).
- textoverlay, clockoverlay, timeoverlay: new "response-time-compensation" property that makes the element render the text or
timestamp twice: Once in the normal location and once in a different sequentially predictable location for every frame. This
is useful when measuring video latency by taking a photo with a camera of two screens showing the test video overlayed with
timeoverlay or clockoverlay. In these cases, you will often see ghosting if the display’s pixel response time is not great,
which makes it difficult to discern what the current timestamp being shown is. Rendering in a different location for each
frame makes it easy to tell what the latest timestamp is. In addition, you can also use the fade-time of the previous frame
to measure with sub-framerate accuracy when the photo was taken, not just clamped to the framerate, giving you a higher
precision latency value.
New tracers
- memory-tracer: New tracer that can track memory usage over time
- pad-push-timings: New tracer for tracing pad push timings
- pcap-writer: New tracer that can store the buffers flowing through a pad as PCAP file
Dot tracer/viewer
- New dots tracer that simplifies the pipeline visualization workflow:
- Automatically configures dot file directory and cleanup
- Integrates with the pipeline-snapshotS tracer to allow dumping pipeline on demand from the gst-dots-viewer web interface
- Uses GST_DEBUG_DUMP_DOT_DIR or falls back to $XDG_CACHE_HOME/gstreamer-dots
- New gst-dots-viewer web tool for real-time pipeline visualization
- Provides interface to browse and visualize pipeline dot files
- Features on-demand pipeline snapshots via “Dump Pipelines” button
- WebSocket integration for live updates
- Uses GST_DEBUG_DUMP_DOT_DIR or falls back to $XDG_CACHE_HOME/gstreamer-dots
- Simple usage:
- gst-dots-viewer (starts server)
- GST_TRACERS=dots gst-launch-1.0 videotestsrc ! autovideosink (runs with tracer)
- View at http://localhost:3000
Debug logging system improvements
- Nothing major in this cycle.
## Tools
- gst-inspect-1.0 documents tracer properties now and shows element flags
- gst-launch-1.0 will show error messages posted during pipeline construction
## GStreamer FFmpeg wrapper
- Add support for H.266/VVC decoder
- Add mappings for the Hap video codec, the Quite OK Image codec (QOI) and the M101 Matrox uncompressed SD video codec.
- Don’t register elements for which we have no caps and which were non-functional as a result (showing unknown/unknown caps).
- The S302M audio encoder now supports up to 8 channels.
- Various tag handling improvements in the avdemux wrappers, especially when there are both upstream tags and additional local
tags.
- Support for 10-bit grayscale formats
## GStreamer RTSP server
- GstRTSPOnvifMediaFactoryClass gained a ::create_backchannel_stream() vfunc. This allows subclasses to delay creation of the
backchannel to later in the sequence, which is useful in scenarios where the RTSP server acts as a relay and the supported
caps depend on the upstream camera, for example.
- The ONVIF backchannel example now features support for different codecs, including AAC.
## VA-API integration
VA plugin
- New VA elements:
- H.266 / VVC video decoder
- VP8 video encoder
- JPEG encoder
- VP9 + VP8 alpha decodebin
Remember that the availability of these elements depends on your platform and driver.
- There are a lot of improvements and bug fixes, to hightlight some of them:
- Improved B pyramid mode for both H264 and HEVC encoding when reference frame count exceeds 2, optimizing pyramid level
handling.
- Enabled ICQ and QVBR modes for several encoders, including H264, H265, VP9 and AV1.
- Updated rate control features by setting the quality factor parameter, while improving bitrate change handling.
- Improved VP9 encoder’s ability to avoid reopening or renegotiating encoder settings when parameters remain stable.
- Added functionality to adjust the trellis parameter in encoders.
- Optimize encoders throughput with the introduction of output delay.
- Added support for new interpolation methods for scaling and improvements for handling interlace modes.
GStreamer-VAAPI is now deprecated
- gstreamer-vaapi has been deprecated and is no longer actively maintained. Users who rely on gstreamer-vaapi are encouraged
to migrate to the va plugin’s elements at the earliest opportunity.
- vaapi*enc encoders have been demoted to a rank of None, so will no longer be autoplugged in encodebin. They have also no
longer advertise dmabuf caps or unusual pixel formats on their input pad template caps.
## GStreamer Video4Linux2 support
- Implemented DMA_DRM caps negotiation
- Framerate negotiation improvements
- Support for P010 and BGR10A2_LE pixel formats
- The V4L2 stateless decoders now support inter-frame resolution changes for AV1 and VP9
- The V4L2 stateful encoders can now handle dynamic frame rates (0/1), and colorimetry negotiation was also improved.
## GStreamer Editing Services and NLE
- Added support for reverse playback with a new reverse property on nlesource which is exposed child property on GESClip
- Input channels reordering for flexible audio channel mapping
- Added support for transition in the ges-launch-1.0 timeline description format
- Added support for GstContext sharing in GESTimeline
- Added basic support for duplicated children property in GESTimelineElement
- validate: Add an action type to group clips
## GStreamer validate
- Added new action types:
- start-http-server: Start a new instance of our HTTP test server
- http-requests: Send an HTTP request to a server, designed to work with our test http server
- HTTP server control endpoints to allow scenarios to control the server behavior, allowing simulating server failures from
tests
- Improved the select-streams action type, adding support for selecting the same streams several times
- Added support for forcing monitoring of all pipelines in validatetest files
- Enhanced support for expected Error messages on the bus
- Added ways to retrieve HTTP server port in .validatetest files
- Added support for lldb in the gst-validate-launcher
## 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.
- The python Meson build option has been renamed to python-exe (and will yield to the monorepo build option of the same name
if set, in a monorepo build context).
- Added an iterator for AnalyticsRelationMeta
- Implement __eq__ for Mtd classes
- Various build fixes and Windows-related fixes.
## GStreamer C# Bindings
- The C# bindings have been updated for the latest GStreamer 1.26 API
## 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 gtk-rs
release cycle.
The latest release of the bindings (0.23) has already been updated for the new GStreamer 1.26 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 1.26 binaries will be tracking the main branch of gst-plugins-rs for starters and then track the 0.14
branch once that has been released (around summer 2025). After that, fixes from newer versions will be backported as needed to
the 0.14 branch for future 1.26.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++.
### New Rust elements
- awstranscriber2, awstranslate: New elements around the AWS transcription and translation services.
- cea708mux: New element that allows to mux multiple CEA708 services into a single stream.
- cdpserviceinject: New element for injecting a CDP service descriptor into closed caption CDP packets
- cea708overlay: New element for overlaying CEA608 / CEA708 closed captions over video streams.
- gopbuffer: New element that can buffer a minimum duration of data delimited by discrete GOPs (Group of Picture)
- hlscmafsink, hlssink3: New single-variant HLS sink elements that can output CMAF (fMP4) or MPEG-TS fragments.
- hlsmultivariantsink: New sink element that can output an HLS stream with multiple variants
- mpegtslivesrc: New source element that can wrap a live MPEG-TS source (e.g. SRT or UDP source) and provides a clock based on
the PCR.
- onvifmetadataextractor: New element that can extract ONVIF metadata from GstMetas into a separate stream
- originalbuffer: New plugin with originalbuffersave / originalbufferrestore elements that allow saving an original buffer,
modifying it for analytics, and then restoring the original buffer content while keeping any additional metadata that was
added.
- polly: New element around the AWS text-to-speech polly services
- quinn: New plugin that contains various QUIC-based elements for working with raw QUIC streams, RTP-over-QUIC (RoQ) and
WebTransport.
- relationmeta: New plugin with elements converting between GstRelationMeta and ONVIF XML metadata.
- New Rust RTP payloaders and depayloaders for AC3, AMR, JPEG, KLV, MPEG-TS (MP2T), MPEG-4 (MP4A, MP4G), Opus, PCMU (uLaw),
PCMA (aLaw), VP8, VP9.
- New rtpbin2 based on rtprecv / rtpsend elements
- speechmatics: New transcriber / speech-to-text and translation element
- New spotifylyricssrc element for grabbing lyrics from Spotify.
- streamgrouper: New element that takes any number of streams as input and adjusts their stream-start events in such a way
that they all belong to the same stream group.
- translationbin: Helper bin around translation elements, similar to the already existing transcriberbin for transcriptions.
- tttocea708: New element for converting timed-text to CEA708 closed captions
- A VVdeC-based H.266 decoder element was added to the Rust plugins, based on the Fraunhofer Versatile Video Decoder library.
For a full list of changes in the Rust plugins see the gst-plugins-rs ChangeLog between versions 0.12 (shipped with GStreamer
1.24) and 0.14.x (shipped with GStreamer 1.26).
Note that at the time of GStreamer 1.26.0 gst-plugins-rs 0.14 was not released yet and the git main branch was included instead
(see above). As such, the ChangeLog also did not contain the changes between the latest 0.13 release and 0.14.0.
## Build and Dependencies
- Meson >= 1.4 is now required for all modules
- liborc >= 0.4.41 is strongly recommended
- libnice >= 0.1.22 is strongly recommended, as it is required for WebRTC ICE consent freshness (RFC 7675).
- The ASIO plugin dropped its external SDK header dependency, so it can always be built and shipped more easily.
- Require tinyalsa >= 1.1.0 when building the tinyalsa plugin
- The srtp plugin now requires libsrtp2, support for libsrtp1 was dropped.
Monorepo build
- The FFmpeg subproject wrap was updated to 7.1
- Many other wrap updates
gstreamer-full
- No major changes
Development environment
- Local pre-commit checks via git hooks have been moved over to pre-commit, including the code indentation check.
- Code indentation checking no longer relies on a locally installed copy of GNU indent (which had different outcomes depending
on the exact version installed). Instead pre-commit will automatically install the gst-indent-1.0 indentation tool through
pip, which also works on Windows and macOS.
- A pre-commit hook has been added to check documentation cache updates and since tags.
- Many meson wrap updates, including to FFmpeg 7.1
- The uninstalled development environment should work better on macOS now, also in combination with homebrew (e.g. when
libsoup comes from homebrew).
- New python-exe Meson build option to override the target Python installation to use. This will be picked up by the
gst-python and gst-editing-sevices subprojects.
## Platform-specific changes and improvements
### Android
- The recommended mechanism to build Android apps has changed from Android.mk to CMake-in-Gradle using
FindGStreamerMobile.cmake. Android.mk support has been deprecated and will be removed in the next stable release. For more
information, see below, in the Cerbero section.
- More H.264/H.265 profiles and levels have been added to the androidmedia hardware-accelerated video encoder and decoder
elements, along with mappings for a number of additional pixel formats for P010, packed 4:2:0 variants and RGBA layouts,
which fixes problems with android decoders refusing to output raw video frames with decoders that announce support for these
common pixel formats and only allow the ‘hardware surfaces output’ path.
### Apple macOS and iOS
- atenc: added an Apple AAC audio encoder
- atdec can now decode audio with more than two channels
- vtenc has received various bug fixes as well as a number of new features:
- Support for HEVC with alpha encoding via the new vtenc_h265a element
- additional rate control options for constant bitrate encoding (only supported on macOS 13.0+ and iOS 16.0+ on Apple
Silicon), setting data rate limits, and emulating CBR mode via data rate limits where CBR is not supported.
- HLG color transfer support
- new "max-frame-delay" property (for ProRes)
- Better macOS support for gst-validate tools which now use gst_macos_main() and support lldb
- The osxaudio device provider exposes more properties including a unique id
- osxaudio will automatically set up AVAudioSession on iOS and always expose the maximum number of channels a device supports
with an unpositioned layout.
- The monorepo development environment should work better on macOS now
- CMake apps that build macOS and iOS apps can consume GStreamer more easily now, using FindGStreamer.cmake or
FindGStreamerMobile.cmake respectively.
- In the near future, CMake in Xcode will be the preferred way of building the iOS tutorials. See below, in the Cerbero
section.
### Windows
- webview2src: new Microsoft WebView2 based web browser source element
- The mediafoundation plugin can also be built with MinGW now.
- The GTK3 plugin has gained support for OpenGL/WGL on Windows
- qsv: Add support for d3d12 interop in encoder, via D3D11 textures
### 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.
General improvements
- New features:
- Python bindings support has been re-introduced and now supports Linux, Windows (MSVC) and macOS. Simply downloading the
official binaries and setting PYTHONPATH to the appropriate directory is sufficient.
- This should make it easier for macOS and Windows users to use Python libraries, frameworks, and projects that use
GStreamer such as Pitivi and gst-python-ml.
- Introspection support has been re-introduced on Linux, Windows (MSVC), and macOS.
- New variants assert and checks to disable GLib assertions and runtime checks for performance reasons. Please note that
these are not recommended because they have significant behavioural side-effects, make debugging harder, and should only
be enabled when targeting extremely resource-constrained platforms.
- API/ABI changes:
- Libsoup has been upgraded from 2.74 to 3.6, which is an API and ABI breaking change. The soup and adaptivedemux2 plugins
are unchanged, but your applications may need updating since libsoup-2.4 and libsoup-3.0 cannot co-exist in the same
process.
- OpenSSL has been updated from 1.1.1 to 3.4, which is an ABI and API breaking change. Plugins are unchanged, but your
applications may need updating.
- Plugins added:
- The svt-av1 plugin is now shipped in the binary releases for all platforms.
- The svt-jpeg-xs plugin is now shipped in the binary releases for all platforms.
- The x265 plugin is now shipped in the binary releases for all platforms.
- All gst-plugins-rs elements are now shipped in the binary releases for all platforms, except those that have C/C++
system-deps like GTK4. For a full list, see the Rust section above.
- Plugins changed:
- The rsvg plugin now uses librsvg written in Rust. The only side-effects of this should be better SVG rendering and
slightly larger plugin size.
- The webrtc Rust plugin now also supports aws and livekit integrations .
- Plugins removed:
- webrtc-audio-processing has been updated to 2.0, which means the isac plugin is no longer shipped.
- Development improvements:
- Support for the shell command has been added to cross-macos-universal, since the prefix is executable despite being a
cross-compile target
- More recipes have been ported away from Autotools to Meson and CMake, speeding up the build and increasing platform
support.
#### macOS
- Python bindings support on macOS only supports using the Xcode-provided Python 3
- MoltenVK support in the applemedia plugin now also works on arm64 when doing a cross-universal build.
#### iOS
- CMake inside Xcode will soon be the recommended way to consume GStreamer when building iOS apps, similar to Android apps.
- FindGStreamerMobile.cmake is the recommended way to consume GStreamer now
- Tutorials and examples still use Xcode project files, but CMake support will be the active focus going forward
#### Windows
- The minimum supported OS version is now Windows 10.
- GStreamer itself can still be built for an older Windows, so if your project is majorly impacted by this, please open an
issue with details.
- The Windows MSI installers are now based on WiX v5, with several improvements including a much faster MSI creation process,
improved naming in Add/Remove Programs, and more.
- Windows installer packages: Starting with 1.26, due to security reasons, the default installation directory has changed
from C:\gstreamer to the Program Files folder, e.g. C:\Program Files (x86)\gstreamer for the 32-bit package on 64-bit
Windows. If you upgrade from 1.24 or older versions, the 1.26 installers will NOT keep using the existing folder.
Nevertheless if you were using C:\gstreamer we strongly recommend you double-check the install location.
- Note for MSI packagers: Starting with 1.26, the installers were ported to WiX 5.0. As part of this, the property for
setting the installation directory has been changed to INSTALLDIR, and it now requires a full path to the desired
directory, e.g. C:\gstreamer instead of C:\.
- Cross-MinGW build no longer supports the creation of MSIs. Please use tarballs.
- MinGW:
- MinGW toolchain has been updated from GCC 8.2 → 14.2 and MinGW 6.0 → 12.0
- The mediafoundation plugin is also shipped in the MinGW packages now.
- The d3d12 plugin is also shipped in the MinGW packages now.
- Rust support has been enabled on MinGW 64-bit. Rust support cannot work on 32-bit MinGW due to differences in exception
handling between our 32-bit MinGW toolchain and that used by the Rust project
- The asio plugin is shipped now, since it no longer has a build-time dependency on the ASIO SDK.
- The new plugin webview2 is shipped with MSVC. It requires the relevant component shipped with Windows.
#### Linux
- Preliminary support for Alma Linux has been added.
- RHEL distro support has been improved.
- Cerbero CI now tests the build on Ubuntu 24.04 LTS.
- curl is used for downloading sources on Fedora instead of wget, since they have moved to wget2 despite show-stopper
regressions such as returning a success error code on download failure.
#### Android
- CMake inside Gradle is now the recommended way to consume GStreamer when building Android apps
- FindGStreamerMobile.cmake is the recommended way to consume GStreamer now
- 1.26 will support both CMake and Make inside Gradle, but the Make support will likely be removed in 1.28
- Documentation updates are still a work-in-progress, help is appreciated
- Android tutorials and examples are now built with gradle + cmake instead of gradle + make on the CI
## Documentation improvements
- Tracer objects information is now included in the documentation
## Possibly Breaking Changes
- qroverlay: the "pixel-size" property has been removed in favour of a new "size" property with slightly different semantics,
where the size of the square is expressed in percent of the smallest of width and height.
- svtav1enc: The SVT-AV1 3.0.0 API exposes a different mechanism to configure the level of parallelism when encoding, which
has been exposed as a new "level-of-parallelism" property. The old "logical-processors" property is no longer functional if
the plugin has been compiled against the new API, which might affect encoder performance if application code setting it is
not updated.
- udpsrc: now disables allocated port reuse for unicast to avoid unexpected side-effects of SO_REUSEADDR where the kernel
allocates the same listening port for multiple udpsrc.
- uridecodebin3 remove non-functional "source" property that doesn’t make sense and always returned NULL anyway.
## Known Issues
- GstBuffer now uses C11 atomics for 64 bit atomic operations if available, which may require linking to libatomic on some
systems, but this is not done automatically yet, see issue #4177.

Stable 1.26 branch
After the 1.26.0 release there will be several 1.26.x bug-fix releases which will contain bug fixes which have been deemed
suitable for a stable branch, but no new features or intrusive changes will be added to a bug-fix release usually. The 1.26.x
bug-fix releases will be made from the git 1.26 branch, which is a stable release series branch.

Schedule for 1.28
Our next major feature release will be 1.28, and 1.27 will be the unstable development version leading up to the stable 1.28
release. The development of 1.27/1.28 will happen in the git main branch of the GStreamer mono repository.
The schedule for 1.28 is yet to be decided.
1.28 will be backwards-compatible to the stable 1.26, 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
release series.

gst-python is an extension of the regular GStreamer Python bindings
based on gobject-introspection information and PyGObject.
It provides two things:
1. "syntactic sugar" in form of overrides for various GStreamer APIs
that makes them easier to use in Python and more pythonic; and
2. 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.
## Prerequisites
These libraries are needed to build gst-python:
- gstreamer core
- gst-plugins-base
- pygobject
You will also need pygobject and glib installed. On debian-based distros
you can install these with:
sudo apt build-dep python3-gst-1.0
Only Python 3 is supported.
## Building
meson setup builddir && ninja -C builddir
meson install -C builddir
## Using
Once installed in the right place, you don't need to do anything in order
to use the overrides. They will be loaded automatically on
```python
import gi
gi.require_version('Gst', '1.0')
from gi.repository import GObject, Gst
```
Note that additional imports will be required for other GStreamer libraries to
make use of their respective APIs, e.g. `GstApp` or `GstVideo`.

The GStreamer team is thrilled to announce a new major feature release
of your favourite cross-platform multimedia framework!
As always, this release is again packed with new features, bug fixes and
other improvements.
The 1.26 release series adds new features on top of the 1.24 series and is
part of the API and ABI-stable 1.x release series.
Full release notes can be found at:
https://gstreamer.freedesktop.org/releases/1.26/
Binaries for Android, iOS, Mac OS X and Windows will usually be provided
shortly after the release.
This module will not be very useful by itself and should be used in conjunction
with other GStreamer modules for a complete multimedia experience.
- gstreamer: provides the core GStreamer libraries and some generic plugins
- gst-plugins-base: a basic set of well-supported plugins and additional
media-specific GStreamer helper libraries for audio,
video, rtsp, rtp, tags, OpenGL, etc.
- gst-plugins-good: a set of well-supported plugins under our preferred
license
- gst-plugins-ugly: a set of well-supported plugins which might pose
problems for distributors
- gst-plugins-bad: a set of plugins of varying quality that have not made
their way into one of core/base/good/ugly yet, for one
reason or another. Many of these are are production quality
elements, but may still be missing documentation or unit
tests; others haven't passed the rigorous quality testing
we expect yet.
- gst-libav: a set of codecs plugins based on the ffmpeg library. This is
where you can find audio and video decoders and encoders
for a wide variety of formats including H.264, AAC, etc.
- gstreamer-vaapi: hardware-accelerated video decoding and encoding using
VA-API on Linux. Primarily for Intel graphics hardware.
(Deprecated, use the new "va" plugin instead)
- gst-rtsp-server: library to serve files or streaming pipelines via RTSP
- gst-editing-services: library an plugins for non-linear editing
- gst-plugins-rs: an exciting collection of well-maintained plugins written
in the Rust programming language (usable from any language)
