No time to try this at the moment, but might that be an artifact of using
the lavfi device? I wouldn't think so, but maybe.

However, now that I understand that for 4 seconds transition you need 4
seconds on each video, I don't understand why you need two parameters,
duration and offset. Why not simply define the duration, and have ffmpeg
calculate the offset as videoDuration minus transitionDuration?
I think
to create the transition.
Again, thanks a lot for your help.
