I was expecting a lot more comments on if this is a necessary feature or if this even belongs in a library like ffmpeg. I think this is bloat, especially when the feature doesn't work flawless, whisper is very limited.

The only item that was discussed was that the subtitle workflow does not seem to be that good, afaict:

You'd be surprised what's in there, a few forms of NNs are already supported for denoising, speech detection.

I think having this flow out to all of the deps of libav is a greater good than notions of lib purity.
