Also, the only codec that works is the MJPEG, any other codec produces

I can't comment on slow-to-process images, but there's a section on the
readability. It's not obvious, so thanks for asking. ;-)
https://www.ffmpeg.org/ffmpeg-bitstream-filters.html#mjpeg2jpeg
So please check whether adding "-bsf:v mjpeg2jpeg" (after the input
file, before the output file - just saying this to be sure) solves that
issue.

I'm sorry but even with your help seems impossible to properly convert
my images.
Actually I'm using ImageMagick with success for both quality
(non-blocky) and chroma-subsampling 4:4:4 (or 4:2:2).
Thanks a lot for your help to better understand ffmpeg :-)
