Then why does `mplayer file.mpeg` works ?? why doesn't it require the
-demuxer option ? There is also multiple demuxer available for the
same format. But for every format, there is a prefered one.

The same as when you simply specify -of mpeg.

Sure. It's also not enough to deduce the desired video bitrate, etc...
But when no format is specified, and that a well know extension
is used, we can decide to automaticaly select the most common format
for this extension, instead of simply failing.
