I know there are JavaScript ports of FFmpeg and I would love to use them. But so far, I never got it working. I tried it with AI and this prompt:

    Make a simple example of speeding up an mp4
    video in the browser using a version of ffmpeg
    that runs in the browser. Don't use any server
    side tech like node. Make it a single html file.

But so far every LLM I tried failed to come up with a working solution.
