  I somehow agree. Also changing the default output file eliminates
some backward compatibility (not that i think so many made use of it).
So if we can avoid it i would rather vote for not changing atm.

  Also it is abuse of the option scheme (assuming every arg starting with
`-' is an option):
If you _must_ specify `-o <outfile>' where is this _optional_ then? ;)

  Well maybe it is the best of the ones listed maybe not;
i dunno. As i said above i would rather not change it.

  Maybe it would also be better to use the extension specified
to detect which muxer to use for output similar to ffmpeg/lavf.
AFAICT that would still hold backward compatibility when done
correctly, meaning if default output stays test.avi the default
muxer chosen would be mplayer avi muxer and -of would generally
only be needed when you want to use lavf or you want to use
an exotic outputname (with non lavf muxer) or just backward
compatibility. Am i missing something? Well, at least i won't
implement it as i have still way to much other things waiting
to be finished or reviewed.
