Efter ett \u00e5rs utveckling sl\u00e4pps GStreamer 1.26, en plattformsoberoende upps\u00e4ttning komponenter f\u00f6r att skapa ett brett spektrum av multimediaapplikationer, fr\u00e5n mediaplayer och konverterare av ljud-\/videofiler till VoIP-applikationer och str\u00f6mningstj\u00e4nster. Koden f\u00f6r GStreamer distribueras under LGPLv2.1-licensen. Separata uppdateringar utvecklas f\u00f6r plugins som gst-plugins-base, gst-plugins-good, gst-plugins-bad, gst-plugins-ugly, samt omslutningen gst-libav och str\u00f6mservicen gst-rtsp-server. N\u00e4r det g\u00e4ller API och ABI \u00e4r den nya versionen bak\u00e5tkompatibel med version 1.0. Binaries kommer snart att f\u00f6rberedas f\u00f6r Android, iOS, macOS och Windows (i Linux rekommenderas att anv\u00e4nda paket fr\u00e5n distributionen). <\/p>\n
Nyckelf\u00f6rb\u00e4ttringar i GStreamer 1.26: <\/p>\n
\n
Kodare och dekodare f\u00f6r videoinstruktionen VVC (Versatile Video Coding), \u00e4ven k\u00e4nd som komprimeringsstandarden H.266, har lagts till. Denna standard har utvecklats i samarbete mellan MPEG-arbetsgrupper (ISO\/IEC JTC 1) och VCEG (ITU-T), med deltagande av f\u00f6retag som Apple, Ericsson, Intel, Huawei, Microsoft, Qualcomm och Sony. H.266 ers\u00e4tter H.265 (HEVC) och erbjuder h\u00f6g effektivitet f\u00f6r \u00f6verf\u00f6ring och lagring av alla sk\u00e4rmuppl\u00f6sningar (fr\u00e5n SD och HD till 4K och 8K), st\u00f6der video med ut\u00f6kat dynamiskt omf\u00e5ng (HDR, High Dynamic Range) och panoramavideo i 360 grader.\n
Kodare och dekodare f\u00f6r videokomprimeringsstandarden LCEVC (Low Complexity Enhancement Video Coding) har lagts till, vilket implementerar ett extra lager med metadata f\u00f6r att f\u00f6rb\u00e4ttra kvaliteten p\u00e5 redan existerande codecs H.26x och MP4\/ISOBMFF.\n
Kodare och dekodare f\u00f6r JPEG XS-bildformatet har lagts till, som marknadsf\u00f6rs som ett l\u00e4ttviktsystem f\u00f6r bildkodning och s\u00e4kerst\u00e4ller minimala f\u00f6rseningar vid kodning och avkodning, och som \u00e4r inriktat p\u00e5 att optimera \u00f6verf\u00f6ringen av sekvenser av bilder med mycket h\u00f6g kvalitet (upp till 8K). JPEG XS g\u00f6r det m\u00f6jligt att avsev\u00e4rt minska den erforderliga bandbredden utan m\u00e4rkbara kvalitetsf\u00f6rluster f\u00f6r det m\u00e4nskliga \u00f6gat.\n
M\u00f6jlighet att substituera och extrahera dolda undertexter f\u00f6r H.264- och H.265-format har lagts till.\n
St\u00f6det f\u00f6r adaptiv str\u00f6mning baserat p\u00e5 HLS (HTTP Live Streaming) och DASH (Dynamic Adaptive Streaming over HTTP) har f\u00f6rb\u00e4ttras. Nya mottagare f\u00f6r multimedia (sink) hlscmafsink och hlssink3 har lagts till f\u00f6r utg\u00e5ng av fragment av CMAF (fMP4) och MPEG-TS, samt hlsmultivariantsink f\u00f6r variabel utg\u00e5ng.\n
MPEG-TS multimedia container packer and unpacker now supports codecs H.266, JPEG XS, AV1, and VP9, as well as SMPTE ST-2038 and ID3 metadata.\n
Packers and unpackers for H.266\/VVC codec have been added to Matroska and ISO MP4 formats. In MP4, unpackers for Hap and Lagarith video formats have been added.\n
Support for SMPTE 2038 has been added, a system for attaching additional data and metadata to multimedia containers.\n
Improved integration with the Vulkan graphics API. Enhanced memory management, color space selection, device management, and fullscreen capabilities. Added support for Vulkan extensions to accelerate H264 and H265 video decoding. Encoder performance using Vulkan has been improved.\n
Enhanced integration with OpenGL. Support for additional color conversion formats and pixel formats has been added. Support for importing streams using DMABufs has been added.\n
Improved integration with the Qt6 library and QML.\n
Expanded components for integration with CUDA and NVIDIA Video Codec SDK. An AV1 encoder based on the NVCODEC API has been added.\n
The gst-d3d12 library with encoders and decoders based on the Direct3D 12 API has been implemented.\n
Support for MIKEY key management on the client side has been added to the RTSP stack.\n
Support for reordering audio channels has been added to audioconvert.\n
Support for OpenGL\/WGL on the Windows platform has been added to the GTK3-based plugin.\n
Support for JPEG and PNG formats has been added to the imagefreeze element.\n
The pitch element has been enhanced to support reverse playback.\n
In the rtmp2 element, authentication mechanisms on RTP servers have been improved. Support for authentication in Limelight CDN has been added.\n
Elements for accelerating H.266 (VVC) decoding, as well as encoding VP8 and JPEG, have been added to the VA-API integration plugin.\n
Elements for working with streams based on the QUIC protocol (raw QUIC, RTP-over-QUIC, and WebTransport) have been added.\n
The gst-plugins-rs set has added 23 new elements or plugins written in Rust. Plugins written in Rust can be used in programs in any language, and working with them is similar to using plugins in C and C++. <\/ul>\n
