Unfortunately, I can't install ffmpeg>=5 to reproduce that and write a patch.

I'm asking timeout until ffmpeg will be at least in ~amd64

Or, I'd also be glad if someone will contribute the patch (and test it with ffmpeg>=5. and I'll check for compatibility with ffmpeg<5)

NB: (ideas about how to patch it)
Comment 9 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2023-04-13 23:14:16 UTC
You can't unmask ffmpeg 5 in a chroot to try it? If everybody said that, then we'd never be able to unmask it, as no packages would be ready.

Unfortunately, I don't, at least, until next month or so.

But, I'm doing all my best to do something with that as fast as possible.

I'll try to buy VPS for that purpose next week, and I hope to make a patch in next holidays.

I couldn't find any fix for this. I doubt there will be any as upstream is dead for years and only a few distributions are still providing it (and it's broken for them too when trying to enable ffmpeg support).

I would simply unconditionally disable ffmpeg support then
