Thanks to a major refactoring of the ffmpeg command-line tool, all the major components of the transcoding pipeline (demuxers, decoders, filters, encodes, muxers) now run in parallel. This should improve throughput and CPU utilization, decrease latency, and open the way to other exciting new feature…
The libavformat library can now read and write IAMF (Immersive Audio) files. The ffmpeg CLI tool can configure IAMF structure with the new -stream_group option. IAMF support was written by James Almer.
The libavcodec library now contains a native VVC (Versatile Video Coding) decoder, supporting a large subset of the codec's features. Further optimizations and support for more features are coming soon. The code was written by Nuo Mi, Xu Mu, Frank Plowman, Shaun Loo, and Wu Jianhua.
A new major release, FFmpeg 7.0 "Dijkstra", is now available for download. The most noteworthy changes for most users are a native VVC decoder (currently experimental, until more fuzzing is done), IAMF support, or a multi-threaded ffmpeg CLI tool. This release is not backwards compatible, removing A…
The FFmpeg community is excited to announce that Germany's Sovereign Tech Fund has become its first governmental sponsor. Their support will help sustain the maintainance of the FFmpeg project, a critical open-source software multimedia component essential to bringing audio and video to billions aro…
FFmpeg now implements a native xHE-AAC decoder. Currently, streams without (e)SBR, USAC or MPEG-H Surround are supported, which means the majority of xHE-AAC streams in use should work. Support for USAC and (e)SBR is coming soon. Work is also ongoing to improve its stability and compatibility. Durin…
The number of issues FFmpeg has in Coverity (a static analyzer) is now lower than it has been since 2016. Our defect density is less than one 30th of the average in OSS with over a million code lines. All this was possible thanks to a grant from the Sovereign Tech Fund.
FFmpeg 7.1 "Péter", a new major release, is now available! A full list of changes can be found in the release changelog. The more important highlights of the release are that the VVC decoder, merged as experimental in version 7.0, has had enough time to mature and be optimized enough to be declared …
A new major release, FFmpeg 8.0 "Huffman", is now available for download. Thanks to several delays, and modernization of our entire infrastructure, this release ended up being one of our largest releases to date. In short, its new features are: Native decoders: APV, ProRes RAW, RealVideo 6.0, Sanyo …
A new minor release, FFmpeg 8.1 "Hoare", is now available for download. Here are some of the highlights: Decoders: xHE-AAC Mps212 (experimental) MPEG-H decoding via libmpeghdec EXIF Metadata Parsing LCEVC: support for parsing and forwarding metadata Vulkan compute-based codecs: ProRes encoding and d…
Ampere has generously donated a server to FFmpeg: an AmpereOne® (Mt. Mitchell) 2U system with 192 Arm cores, 512 GB of RAM, 24 NVMe bays and 2×25G networking, weighing in at 28 kg. Thank you, Ampere! To celebrate, Dascha (daschasara) answered FFmpeg's call for non-AI artwork and drew this piece for …
在人工智能和大语言模型（LLM）的语境下，RAG、知识库和上下文是构建智能问答系统的三个核心概念。 它们的目的都是为了让 AI 获取外部信息，但各自的角色、范围和工作阶段有所不同。 核心概念定义 1. 知识库（Knowledge Base） 本质：结构化信息管理系统，核心目标是知识的存储和检索 形态：可以是结构化图谱/规则引擎，也可以是非结构化文档 特点：静态存储系统，需要定期更新维护 2. RAG（Retrieval-Augmented Generation） 本质：检索增强生成技术框架 核心思想：让大模型在回答问题时，先从外部知识库中检索相关内容，再基于检索结果生成回答 组成：由离线索引流…
位数和长度对比 IPv4 位数：32位 字节数：4字节 地址数量：约43亿个（2³² ≈ 4.3×10⁹） 表示方式：点分十进制（如：192.168.1.1） 格式：共4段，每段0-255 IPv6 位数：128位 字节数：16字节 地址数量：约3.4×10³⁸个（几乎无限） 表示方式：冒号分隔的十六进制（如：2001:0db8:85a3::8a2e:0370:7334） 格式：共8组，每组4个十六进制数字 关键差异 长度对比：IPv6的地址长度是IPv4的4倍（128位 vs 32位） 地址空间：IPv6的地址空间比IPv4大约10²⁸倍，可以为地球上每一粒沙子都分配多个IP地址 表示方法：…
