The question is, why shouldn't it?
cat *.jpg | ffmpeg -f image2pipe -c:v mjpeg -i - works as far as I know,

No, in fact image2pipe isn't officially documented anywhere in FFmpeg.
(Note to self: Create a ticket for that.)
So maybe I'm missing something about how the image2pipe demuxer works.

This works perfectly, thanks.
