[FFmpeg-user] concat demuxer filter_complex (fade)

I'm not quite sure if my previous message was sent (it doesn't appear on
ffmpeg-archive.org so I'll write this message to be comprehensive even
without my message sent on 2020-04-13 12:54 UTC

Since I'd like to add the feature to my script to be able to add transitions
between the elements and since when using the concat demuxer for making the
slideshow the different images
indistinguishable for the filter chain, I have to think of another way to
make a slideshow while still having the images distinguishable for the
filter chain
(I don't like it to preprocess the Images by making a Video of each Image
because of various reasons).

A fact that makes this even harder, is that I'd like to be still able to set
different durations for different images (like it is possible in the input
file for the concat demuxer (see  https://trac.ffmpeg.org/wiki/Slideshow
<https://trac.ffmpeg.org/wiki/Slideshow>  ).

Since I didn't found a solution that meets that kind of requirements, I'm
asking you if someone of you might have an Idea how to do this. 

With kind regards and thanks in advance
