# Fabrice Bellard ![[50 Resources/51 Attachments/51.03 Public/2026-03-18 Fabrice Bellard.jpg|400]] Fabrice Bellard is a French computer scientist renowned for creating foundational [[Open Source]] projects including [[FFmpeg]], QEMU, and the Tiny C Compiler (TCC). His work is characterized by exceptional technical depth and efficiency—single-handedly building systems that entire teams struggle to replicate. He has been called one of the most productive programmers in history. Beyond his major projects, Bellard has set records in computing pi digits (using a desktop PC to beat supercomputers), created a JavaScript PC emulator that runs Linux in browsers, and developed QuickJS (a small embeddable JavaScript engine). His projects demonstrate mastery across domains: multimedia, virtualization, compilers, numerical algorithms, and telecommunications (he wrote a 4G LTE base station implementation). ## Major Projects | Project | Year | Description | | -------------------- | ---- | ------------------------------------------------- | | **FFmpeg** | 2000 | Multimedia framework used by YouTube, VLC, Chrome | | **QEMU** | 2003 | Machine emulator and virtualizer | | **TCC** | 2001 | Tiny C Compiler (compiles C in milliseconds) | | **QuickJS** | 2019 | Small, embeddable JavaScript engine | | **JSLinux** | 2011 | JavaScript PC emulator running Linux in browser | | **LZEXE** | 1989 | DOS executable compressor | | **BPG** | 2014 | Better Portable Graphics image format | | **LTE Base Station** | 2014 | Software-defined 4G implementation | ## Achievements - **1997**: Won International Obfuscated C Code Contest (IOCCC) - **2000**: Computed pi to 2.7 trillion digits using a desktop PC - **2009**: Broke pi record again with 2.7 trillion digits - **2011**: Created JSLinux—Linux running in JavaScript - **2019**: Released QuickJS with near-complete ES2020 support ## Philosophy Bellard's work exemplifies: - **Efficiency**: Minimal code, maximum capability - **Solo development**: Most projects developed single-handedly - **Deep understanding**: Builds from first principles - **Practical impact**: Projects widely adopted in industry ## Impact His software runs on billions of devices: - FFmpeg libraries power most video playback worldwide - QEMU underlies KVM virtualization in cloud computing - TCC enables fast C compilation for development/scripting ## References - https://bellard.org - https://en.wikipedia.org/wiki/Fabrice_Bellard - https://ffmpeg.org - https://www.qemu.org ## Related - [[FFmpeg]] - [[Open Source]]
