ffmpeg: ignore extra data streams with `-dn` (fixes #2) 

Sometimes, video files will arrive with a timecode data stream
that causes `-map 0` to error out due to the stream not being
supported in the output container. These data streams generally do
not matter, so tell ffmpeg to ignore them rather than choking on
them.
