man is always your friend ;-)
On my system xubuntu 13.2 with this version of ffmpeg installed:
ffmpeg version 0.8.6-4:0.8.6-0ubuntu0.12.04.1, Copyright (c) 2000-2013
the Libav developers
built on Apr 2 2013 17:00:59 with gcc 4.6.3
*** THIS PROGRAM IS DEPRECATED ***
This program is only provided for compatibility and will be removed in a
future release. Please use avconv instead.
man ffmpeg gives this information (several screens down):
-target type
Specify target file type ("vcd", "svcd",
"dvd", "dv", "dv50", "pal-vcd", "ntsc-svcd", ... ).
All the format options (bitrate, codecs, buffer sizes) are
then set automatically. You can just type:
ffmpeg -i myfile.avi -target vcd /tmp/vcd.mpg
Nevertheless you can specify additional options as long
as you know they do not conflict with the standard, as in:
ffmpeg -i myfile.avi -target vcd -bf 2 /tmp/vcd.mpg
