Wow! Is there an easy way to combine these subtitles with the video in the browser?

It looks pretty easy, but I'm not going to do it, if someone else wants to.

Not a format I would recognize, but I am not an expert in the area. Two lines of awk would convert it to srt I guess.

It's even closer to WebVTT, just had to add the line "WEBVTT" to the top and replace all square brackets with line breaks:

    curl https://jonatron.github.io/fosdem2023whisper/files/celebrating_25_years_of_open_source.webm.txt | ( echo "WEBVTT"; sed -e 's/^\[\|\]  \?/\n/g' ) >celebrating_25_years_of_open_source.webm.vtt

Plays in the browser with HTML like this:

    <video
        controls
        src="https://video.fosdem.org/2023/Janson/celebrating_25_years_of_open_source.webm"
    >
        <track
            default
            srclang="en"
            src="celebrating_25_years_of_open_source.webm.vtt"
        >
    </video>

A sidenote, but adding subtitles to pure audio in HTML is surprisingly difficult!

Does it not work to put a track element inside an audio element?

You can try to fake it as a video, but in my experience, it is difficult to properly format the element so that the subtitles or captions actually shows

https://developer.mozilla.org/en-US/docs/Web/HTML/Element/au...

> The <audio> element doesn't directly support WebVTT. You will have to find a library or framework that provides the capability for you, or write the code to display captions yourself. One option is to play your audio using a <video> element, which does support WebVTT.

Is my version of sed dumb, or is 's/^\[\|\] \?/\n/g' effectively a no-op? Or did HN garble something?

I used GNU sed on Ubuntu. The only difference I notice is that you have one space where I had two, but that difference shouldn't matter actually. Perhaps your sed has a different opinion on which of the backslashes should be there.

You can access the resulting WebVTT files here: https://github.com/tuukka/fosdem2023whisper/tree/feat/webvtt...

Once again macOS non-standard utilities bite me.

     -E      Interpret regular expressions as extended (modern) regular expressions rather than basic regular expressions (BRE's)

    -r      Same as -E for compatibility with GNU sed.

Thanks for providing the complete set of vtt files. I found some interesting transcription errors in the talk on Elliptic curves in FOSS. For example "jealous two curves" instead of "genus two curves" and "ethyl curbs" instead of "elliptical curves"
