also id like to say that people should try to move code from soc to
main svn. The bigger the code in soc becomes the harder it will
be to ever move this into main svn.
Changes like this patch make the code less acceptable not more.
Ive said it already, and i say it again, parameter parsing must be
done cleanly, AVOptions are there and can be used, if you implement the
same in 5 times as much code with strcmp & scanf you just added yourself
reverting work if the code is supposed to reach main svn
