Some (but not all) of the resulting files show every track twice in ffmpeg. I posted an example file and output at https://ffmpeg.org/trac/ffmpeg/ticket/1378.

VLC shows correct number of tracks.
mediainfo shows the correct number of tracks.
Quicktime shows the correct number of tracks.
muxmovie shows the correct number of tracks.
Dumpster (Quicktime tool to review container structure) shows the correct number of tracks.
... and ...
ffmbc shows the correct number of tracks.

ffmpeg doubles all tracks.
