FFglitch: the multimedia bitstream editor

In this talk I will present FFglitch, a multimedia bitstream editor written to create glitch art and codec art.

As an FFmpeg developer, I have always been amazed by the visual glitches that are created when we get something wrong in the code. But since those glitches are considered bugs, and not features, we have 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.
