Yeah, avidemux does it all. I have used for mp4, flv, avi, mpg and recently
some MKVs (it doesn't have this one down pat, though, quite some options to
fudge with it for optimal results).

Just hit "copy" for video and audio encoding options. IIRC, it simply passes
the file to mplayer, reads the output and resets the encoding options to as
close as possible-- if not exactly as-- the original.
