I started testing last sunday, and for the life of me I could not reproduce the issue.
(My Windows did do an update that morning.)
Today the problem was back, and I narrowed it down to running FFmpeg.exe from (a subfolder) from the desktop.
I am totally clueless how this can happen. (The previous tests from last sunday where the problem did not occur also was from the desktop.)
(Again, it’s a delay introduced before ANY transcoding, but no delay in starting FFmpeg itself.)
Same FFmpeg version run from another location is fine.
Very, very strange.
