-     asfdemux: Be more lenient towards malformed header

-     VLC counts METADATA as 1 even if the specification states you must not.

-     This leads to asfdemux failing since there are no bytes left when asfdemux

-     tries to extract the "last" header.

-     Do not fail hard in this case and try to proceed when everything else went

-     fine.

-     So at least gst-discoverer will see what's in the file.

+     docs: generate hotdoc configs for libraries with our helper script

+     With this patch, configure time is identical no matter whether doc is

+     enabled or not.

+     The configuration files also now contain explicitly-listed sources with

+     no wildcards.

+     For the four libraries where hotdoc needs to use clang to generate the

+     documentation (as opposed to the rest of the libraries where hotdoc uses

+     the gir), the script will call pkg-config to determine the appropriate

+     C flags.

+     This means a side effect of this patch is that pkg-config files are now

+     generated for the gstadaptivedemux and gstopencv libraries.

-     gstreamer-full: add full static support

-     Allow a project to use gstreamer-full as a static library

-     and link to create a binary without dependencies.

-     Introduce the option 'gst-full-target-type' to

-     select the build type, dynamic(default) or static.

-     In gstreamer-full/static build configuration gstreamer (gst.c)

-     needs the symbol gst_init_static_plugins which is defined

-     in gstreamer-full.

-     All the tests and examples are linking with gstreamer but the

-     symbol gst_init_static_plugins is only defined in the gstreamer-full

-     library. gstreamer-full can not be built first as it needs to know what plugins

-     will be built.

-     One option would be to build all the examples and tests after

-     gstreamer-full as the tools.

-     Disable tools build in subprojects too as it will be built at the end of

-     build process.

 ## Major new features and changes

-### Discourse forum and Matrix chat space

+### H.266 Versatile Video Coding (VVC) codec support

--   The new Discourse forum and Matrix chat space are now our preferred communication channels for support and developer chat.

+-   The H.266 / VVC video codec is a successor to H.265 / HEVC and is standardised in ISO/IEC 23090-3.

--   The mailing lists and IRC channel are on their way to being phased out, but Discourse can be used via e-mail as well.

+-   A new h266parse element was added, along with parsing API, typefinding support and some codec utility functions in the

+    gst-plugins-base utility library.

--   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.

+-   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.

-### Playbin3, decodebin3 now stable and default

+-   The FFmpeg H.266 decoder is exposed now (from FFmpeg 7.0 onwards).

--   After a year of stability, testing and more improvements, playbin3, and its various components (uridecodebin3, decodebin3

-    and urisourcebin), are now the recommended playback components.

+-   H.266 / VVC muxing and demuxing support was implemented for MP4, Matroska and MPEG-TS containers.

--   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.

+-   A VVdeC-based H.266 decoder element was added to the Rust plugins, based on the Fraunhofer Versatile Video Decoder library.

-Improvements in this cycle:

+### JPEG XS image codec support

--   Better support missing/faulty decoders, attempt to use another one or gracefully un-select the stream.

+-   JPEG XS is a visually lossless, low-latency, intra-only video codec for video production workflows, standardised in ISO/IEC

+    21122.

--   Many fixes for more complex gapless and instant-switching scenarios

+-   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.

--   Lower latency for live pipelines

+### Low Complexity Enhancement Video Coding (LCEVC) support

--   Fix for “chained” streams (ex: Ogg, or PMT update in MPEG-TS)

+-   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.

--   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).

+-   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.

-### GstMeta serialization/deserialization and other GstMeta improvements

+### Closed captions 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.

+-   New H.264 and H.265 closed captions extractor and inserter elements.

--   Simplified GstCustomMeta registration with gst_meta_register_custom_simple() for the simple case where tags and transform

-    functions are not needed.

+    -   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.

--   GstMetaClearFunction clears the content of the meta. This will be called by buffer pools when a pooled buffer is returned to

-    the pool.

+    -   The inserter elements do something similar and insert caption SEIs into the H.264 or H.265 bitstream, taking into

+        account frame ordering.

--   Add gst_meta_info_new() and gst_meta_info_register() to register a GstMeta in two steps for easier extensibility.

+    -   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).

-### New unixfd plugin for efficient 1:N inter-process communication on Linux

+-   cdpserviceinject: New element for injecting a CDP service descriptor into closed caption CDP packets

--   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.

+-   cea708overlay: New element for overlaying CEA608 / CEA708 closed captions over video streams.

--   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.

+-   The cc708overlay element has been deprecated in favour of the cea708overlay element from the Rust plugins set.

-### New GstMeta for SMPTE ST-291M HANC/VANC Ancillary Data

+-   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.

--   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.

+-   cea708mux: New element that allows to mux multiple CEA708 services into a single stream.

--   Add with gst_buffer_add_ancillary_meta() and retrieve with gst_buffer_get_ancillary_meta() or

-    gst_buffer_iterate_ancillary_meta().

+-   cccombiner has two new properties:

--   Supported by the newly added AJA sink and source elements

+    -   "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.

-### DSD audio support

+    -   "schedule-timeout" to support timing out captions without EOS

--   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.

+-   tttocea708: New element for converting timed-text to CEA708 closed captions

--   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.

+-   Miscellaneous improvements and spec compliance fixes

-### Analytics and Machine Learning

+### Speech to Text, Translation and Speech Synthesis

--   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.

+-   awstranscriber2, awstranslate: New elements around the AWS transcription and translation services.

--   Three types of metadata are already defined in the library: object detection, classification and tracking.

+-   polly: New element around the AWS text-to-speech polly services

--   A new objectdetectionoverlay element has been merged that draws the bounding boxes and the classes from the object detection

-    and classification metadata types.

+-   speechmatics: New transcriber / speech-to-text and translation element

--   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.

+-   translationbin: Helper bin around translation elements, similar to the already existing transcriberbin for transcriptions.

--   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.

+### HLS DASH adaptive streaming improvements

--   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.

+-   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.

-### Qt5 + Qt6 QML integration improvements

+-   dashsink has received period duration fixes for dynamic MPDs and some memory leak fixes.

--   The Qt5 qmlglsink, qmlgloverlay, qmlglmixer received support for directly consuming BGRA and YV12 video frames without a

-    prior glcolorconvert.

+-   hlscmafsink, hlssink3: New single-variant HLS sink elements that can output CMAF (fMP4) or MPEG-TS fragments.

--   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.

+-   hlsmultivariantsink: New sink element that can output an HLS stream with multiple variants

--   qml6d3d11sink is a new Direct3D11 Qt6 QML sink for Windows as an alternative to the existing qml6glsink.

+### splitmuxsrc, splitmuxsink: lazy loading and dynamic fragment addition

-### DRM Modifier Support for dmabufs on Linux

+-   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.

-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 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:

-In GStreamer, it’s used on the capture side (v4l2src, pipewire), hardware-accelerated video decoders and encoders, OpenGL

-integration, Wayland renderers, etc.

+    -   You can now add fragments directly to splitmuxsrc and provide the offset and duration in the stream:

-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”.

+        -   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.

-With GStreamer 1.24 there is now full DRM modifier support and complex non-linear formats can be supported and negotiated

-between components.

+        -   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.

-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.

+    -   splitmuxsrc no longer keeps all files open, but instead only keeps 100 files open by default, configurable with the

+        "num-open-fragments" property.

-See the GStreamer DMA buffers design documentation for more details.

+    -   There is a new "num-lookahead" property on splitmuxsrc to trigger (re)opening files a certain distance ahead of the play

+        position.

-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.

+    -   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.

-New API has been added for easy handling of these new caps:

+### MPEG-TS container format improvements

--   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()

+-   The MPEG-TS muxer and demuxer gained support for

--   GST_VIDEO_DMA_DRM_CAPS_MAKE

+    -   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)

--   GST_VIDEO_FORMAT_DMA_DRM

+-   mpegtsmux gained support for muxing ID3 metadata into the TS stream, as well as SMPTE 302M audio.

-### OpenGL integration enhancements

+-   It’s also possible to disable sending SCTE-35 null (heartbeat) packets now in mpegtsmux by setting the

+    "scte-35-null-interval" to 0.

--   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.

+-   tsparse now handles 192-byte M2TS packets

--   Improved support for dmabuf use cases. The glupload element now supports the new and improved dmabuf negotiation with

-    explicit modifiers.

+-   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.

--   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.

+### Matroska container format improvements

--   Add support for a ‘surfaceless’ EGL context using EGL_MESA_platform_surfaceless.

+-   H.266 / VVC video muxing and demuxing support

--   Expose Vivante Framebuffer build-related files (pkg-config, gir) as public API

+-   matroskamux

--   Add support for more video formats:

+    -   was ported to the GstAggregator base class, ensuring defined-latency muxing in live streaming pipelines.

+    -   gained rotation tag support

-    -   A420 8/10/12/16-bit.

-    -   A422 8/10/12/16-bit.

-    -   A444 8/10/12/16-bit.

-    -   I420 10/12 bit.

-    -   RBGA.

+-   matroskademux now also supports seeks with a stop position in push mode.

--   Add support for tiled video formats

+### ISO MP4 container format improvements

-    -   NV12_16L32S (Mediatek format)

-    -   NV12_4L4 (Verisilicon Hantro format)

+-   can mux and demux H.266 / VVC in MP4 now

--   glcolorconvert now has API for retrieving shader strings for:

+-   can demux Hap video now, as well as Lagarith lossless video and ISO/IEC 23003-5 raw PCM audio.

-    -   swizzling (reordering components).

-    -   YUV->RGB conversion.

-    -   RGB->YUV conversion.

+-   qtdemux handles keyunit-only trick mode also in push mode now

--   Add more helpers for information about a particular video and/or GL format e.g. number of components, bytes used, or pixel

-    ordering.

+-   support for ISO/IEC 23001-17 raw video in MP4 in qtdemux and isomp4mux.

--   glvideomixer has new sink pad properties sizing-policy, xalign, yalign matching compositor.

+-   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.

--   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.

+SMPTE 2038 ancillary data streams

-### Vulkan integration enhancements

+-   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.

--   Add support for the Vulkan H.264 and H.265 decoders.

+-   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:

--   Add support for timeline semaphores.

+    -   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.

--   Optionally use newer Vulkan functions for format selection.

+    -   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.

--   Add support for GPU-assisted validation.

+        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.

--   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.

+        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).

-### CUDA / NVCODEC integration and feature additions

+    -   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.

--   New cudaipcsrc and cudaipcsink elements for zero-copy CUDA memory sharing between processes

+### Analytics

--   New nvJPEG library based nvjpegenc JPEG encoder element

+-   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.

--   The NVIDIA desktop GPU decoder nvh264sldec, nvh265sldec, nvvp8sldec, and nvvp9sldec elements were renamed to nvh264dec,

-    nvh265dec, nvvp8dec, and nvvp9dec, respectively.

+-   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.

--   GStreamer NVIDIA H.264 and H.265 encoders except for nvh264enc and nvh265enc gained support for CEA708 Closed Caption

-    inserting.

+-   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.

--   OpenGL memory support is added to nv{cuda,autogpu}h264enc and nv{cuda,autogpu}h265enc elements

+-   onvifmetadataextractor: New element that can extract ONVIF metadata from GstMetas into a separate stream

--   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.

+-   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.

-### RTP stack improvements

+-   relationmeta: New plugin with elements converting between GstRelationMeta and ONVIF XML metadata.

--   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.

+-   Improved Python bindings for a more Pythonic interface when iterating over GstRelationMeta’s mtd

--   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.

+### Vulkan integration enhancements

--   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.

+-   Vulkan Integration Improvements:

--   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:

+    -   Memory Management: Non-coherent memory is now invalidated when mapping for read in vkmemory.

-    -   “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.

+    -   Color Space Selection: The vkswapper component now chooses the correct color space based on the format.

-    -   “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.

+    -   Vulkan Plugin Compatibility: Support added for cases where glslc is not available for building Vulkan plugins, along

+        with GLSL compiler support for glslang.

--   RTP payloaders and depayloaders now have an “extensions” property for retrieving the list of currently enabled RTP header

-    extensions.

+    -   Fullscreen Quad Updates: Improved support for setting NULL input/output buffers and added checks for unset video info.

--   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.

+    -   Vulkan Buffer Pool Enhancements: Buffer pool access flags and usage configurations have been refined, offering better

+        performance for video decoding and encoding.

--   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.

+-   Decoder/Encoder Improvements:
