my scripts for transcoding into mp3 format have stopped working after upgrade from media-video/ffmpeg-6.1.2 to media-video/ffmpeg-6.1.2-r1. specific error message is "Encoder not found". there was no change in USE flags, nor any warnings from emerge.

Flag was renamed from mp3 to lame in https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=00eddc65d7bd9ecaa9973fd46e544bbbfe5c9479 and then trickled down to 6.*. See --disable-libmp3lame in your config flags.
Did worry that it'd affect a few users given it came without warning, but yes, just enable USE=lame instead as noted in comment #2 (sorry for the inconvenience). The USE was often confused as being required for playback, thus the renaming alongside other refactoring.

(maybe could add it anyway, albeit only tomorrow, can't right now)
(In reply to Ionen Wolkens from comment #6) > (maybe could add it anyway, albeit only tomorrow, can't right now) thank you. and please do not forget to update USE flag description, it still says "prefer" and not "required".

That's the global USE description (ffmpeg does not have its own), honestly I don't see why it mentions prefers (it shouldn't say required either, it should be something more neutral). Technically an alternative exists, but it's not packaged (libshine), so it could've made sense in that context.
