Ok, thanks to the FAQ, it's done.
But now I have a file size problem.

I joined 7 .flv videos that in total make 285M.
The total file is a
812M avi file or
892M flv file or
891 mpg file.

I did:
ffmpeg -i vision-1.flv -sameq i1.mpg
...
cat i* > t.mpg
ffmpeg -i t.mpg -sameq o.avi
ffmpeg -i t.mpg -sameq o.flv
