FFglitch: when bugs become features (Ramiro)

• Prior knowledge: Slightly nerdy (linux terminal, ffmpeg related) but still cool if you don’t need to understand it all
• Format: Demotime
• Language: English

In this talk I will present FFglitch, a multimedia bitstream editor. As a former FFmpeg developer, I was always amazed by the glitches that were created when we got something wrong in the code. But since those glitches were considered bugs, and not features, we had to fix the bugs and get rid of the glitches. FFglitch was born as a project where those glitches are features, and not bugs. FFglitch leverages the FFmpeg codebase to turn decoders into bitstream editors. It allows precise editing of bitstream values, along with built-in scripting support, real-time input from HID and MIDI controllers, and network communication. Incredibly overengineered and vastly underdocumented since its inception, this glitch art project is finding new uses in codec vulnerability research.

Bio: Hi, I’m Ramiro Polla.

• I have always loved hacking things to learn and understand how they work.
• I have always loved the technical aspects of any music-making or video-making thing.
• I have been involved in Open Source development since the early 2000s.
• I have been part of hackerspaces for over a decade.
• I love working on useless projects that make people tilt their heads and ask “but why?”.
• Lately I have been focussing mostly on FFglitch.
