I have had some success using ogg vorbis files (with ".ogg"
extension). Some success, but also some segfaults.

If I had stuck with using audio, I would have tried making a file with
a blank video channel, like this:

 gst-launch-1.0 videotestsrc pattern=2 ! theoraenc ! oggmux name=mux \
    ! filesink location=video.ogv filesrc location=audio.ogg \
    ! oggdemux ! mux.

BTW, the list of extensions that trigger gstreamer magic is:

  char *video_extensions[] =
    {".avi", ".ogg", ".ogv", ".mpg",  ".flv", ".mpeg",
     ".mov", ".mp4", ".wmv", ".webm", ".mkv", ".3gp", ".gif", NULL};

You could try just renaming your audio to one of these, and see what
happens.
