Your version of ffmpeg is ancient. Your issue may have long been
solved. Please get hold of a recent version of ffmpeg. If you can't
find a Ubunuto repository which provides latest builds, grab a binary
from here:
https://johnvansickle.com/ffmpeg/
(Preferred: Left column, git builds - not the releases.)
I have no idea whether the file creation or the interpretation of the
created file is different in recent ffmpeg (I assume the former), but
it just works with webm.
