Short answer: In ffmpeg terms, the format is called "matroska". Try "-f
Long answer: I too was confused a few times initially, and I assume
other users will be, like you. I tried to see whether format names
could be "aliased" within ffmpeg, but failed to get it correct
quickly[*]. Otherwise, I would have submitted a patch.
[*] The aliases I define are apparently coded into matroska_doctypes,
ffprobe on the resulting file gives:
[matroska,webm @ 0xa108180] Unknown EBML doctype 'matroska,mkv'
