Depending on the font used and the size of it, an 'm' and 'rn' can
easily look the same.  Of course, if someone was copying a list of
codecs for this GUI they may have made this mistake too.

Also, I don't think there is a codec called "libopencore_ammb" anyway,
certainly not one in ffmpeg, so I can only assume it is what you are
looking for.
