FFmpeg
FFmpeg是一套开源的跨平台音视频处理框架，广泛应用于音视频的录制、转换、编解码、流媒体传输及后期处理等场景。它支持几乎所有主流的音视频格式与编解码协议，提供命令行工具及可供开发者调用的函数库（如libavcodec、libavformat等），是众多多媒体软件和平台的底层基础组件。
核心事实
时间轴 (近 90 天)
yt-dlp 下载的音频和视频通常是分离的独立流，需要通过 FFmpeg 进行混流合并
关闭 ModelStack 的局域网访问后，Harness 会立即失去本地音视频生成能力，转而尝试从免费网站爬取图片或用 FFmpeg 模拟视频
文件转换服务的系统依赖包括：文档转换需要 LibreOffice、图像处理需要 ImageMagick 或 GraphicsMagick、音视频转码依赖 FFmpeg
FFmpeg is used across Chrome browser, VLC player, YouTube backend processing systems, and built-in media frameworks of various operating systems
FFmpeg has over a million lines of C code and extensive hand-written SIMD assembly optimizations
Cursor gave free usage credits to developers of the open-source project FFmpeg
Offering free credits to FFmpeg developers serves as a high-value real-world test and brand endorsement for Cursor
FFmpeg's codebase involves low-level C code, assembly optimizations, platform-specific conditional compilation, and performance-critical codec algorithms, making it a demanding test for AI tools' comprehension
FFmpeg was created in 2000 by French programmer Fabrice Bellard, with 'FF' standing for 'Fast Forward'
FFmpeg includes core components like libavcodec (codec library), libavformat (container format library), and libavfilter (filter library), supporting hundreds of audio/video codec formats under an LGPL/GPL dual license
