OK, I thought so.

OK, I found these already, but not all of them.

I know that site. My problem is, that I don't find some options from the
mplayer site in the ffmpeg man pages or ffmpeg-documentation. 

So my concrete question is: what is ffmpeg-syntax-equivalent for

profile=htdxnpal
me_quality=6
quant_type=mpeg
trellis
interlacing
chroma_me
chroma_opt
vhq=4

Additional questions are:

Where should I look for the syntax of these parameters?

Exists a rule to deduce the commandline like e.g. "if you have a=b in
mencoder, then the ffmpeg-commandline is X=Y" or "look in the xvid
sourcefile bla.h, get the name of the xvid parameter there and write x=y
in the ffmpeg-commandline."?

the question in general behind this is: How to transport parameters to
an external encoding lib (like e.g. x264, although this part seems to be
way better documented.)

Thanks for this useful hint!
