What is FFmpeg?

FFmpeg is a widely used open-source multimedia framework, integral to video and audio processing pipelines. According to Jean-Baptiste Kempf, as of May 2026, FFmpeg’s core community is small, and the project faces challenges from AI-generated security reports and volunteer burnout.

  • May 2026 - Jean-Baptiste Kempf said the core community of FFmpeg is ten to fifteen people, who are responsible for maintaining the code.
  • May 2026 - Kempf mentioned that VLC WebAssembly compiles all VLC and FFmpeg to run inside a JavaScript virtual machine.
  • May 2026 - Kempf estimated that 80-plus percent of multimedia pipelines are dependent on a VideoLAN project, which includes FFmpeg.
  • May 2026 - Kempf observed that teenagers have written more assembly in FFmpeg than Google engineers, highlighting the project’s reliance on volunteer contributions.

In the evidence

By the numbers

The core maintainer communities for VLC and FFmpeg are tiny: 5 people for VLC, 10-15 for FFmpeg.

“The core community of VLC is five people. The core community of FFmpeg is ten to fifteen, and we are the ones who are going to maintain your code.”

Contrarian take

Google AI-generated security reports on FFmpeg before fixes were ready, burdening unpaid volunteers while Google publicized its AI's performance to the press.

“Recently what changed was Google started using AI to create security reports on an open source project, FFmpeg. Volunteers had to deal with that. They did, they provided very limited funding, and they even went to the media first announcing how good their AI was before the issues could be fixed.”

Company & tool watch

VLC WebAssembly: VLC and FFmpeg are now being compiled to WebAssembly to run entirely inside a browser's JS VM, reversing the prior model of embedding a browser inside VLC.

“Today we have the opposite, where we have VLC WebAssembly, where we compile all VLC and FFmpeg to decode, to run VLC in inside the JavaScript virtual machine with WebAssembly.”

By the numbers

Only 1% of open source contributors to projects like FFmpeg and VLC stay long-term.

“One percent chance that someone comes and stays. One percent.”

By the numbers

FFmpeg is running on an estimated 100 million to 1 billion CPUs simultaneously at any given moment.

“As we speak easily 100 mil- order of magnitude 100 million, maybe even a billion CPUs as we speak.”

Worth quoting

Teenagers have written more assembly code in FFmpeg than Google engineers.

“Teenagers have written more assembly in FFmpeg than Google engineers.”
Jean-Baptiste Kempf · 6 May 2026
By the numbers

Over 80% of video-processing pipelines using FFmpeg are dependent on at least one VideoLAN project.

“I would put a finger in the air and say 80-plus percent of those pipelines are dependent on a VideoLAN project.”
