Don't be sorry! This is a peer-to-peer list AFAIK and anyone can pop
in at their leisure. Noone is *required* to comment.
But thanks for your comments!

I have added a video recoding function to my existing non-threaded
application now. And as I feared it is not very good because it
disappears out into nothing-land for 5 minutes when it recodes a 5
minute test video.
Looks like ffmpeg is actually "playing" the video at normal speed and
saving a modified stream to the file.
So it would be 45 minutes to recode a 45 min video with the wrong
codec to begin with...

So I will try my hand at using the hints from the article I linked to
in order to have some user feedback. Maybe just write a period to the
console every second and add a linefeed and the time in minutes every
minute.
This way the user can see something is happening at least.
But it requires me to run the actual process in a separate thread of
course.
