Mencoder basically uses the same libraries as ffmpeg (and a few more,
IIRC). Having used both for years for standard (ripping, replaying,
recencoding) tasks as well as for somewhat exotic stuff like streaming
video sources from gadgets live into VJ mixers using all kind of filter
in between I would say that mencoder is the app of choice if it gets the
job done because it has much simpler options.
FFMPEG comes into play whenever simpler options fail. As you noticed
there are more options than anyone could memorize trying to cover even
the most exotic use-cases.
Your command line, BTW, looks very much like my standard section in
.mplayer/config for live streaming/encoding from a webcam. I'd suppose
reading the extra HTML-doc for mplayer. It's a relatively easy read.
Getting into FFMPEG is certainly worth it, too - if you have specific
needs.
