Maybe not.. Anyways I downloaded the latest version (I believe). I ran the original command line (w/o "-dn"), same error message. (BTW: why does it say "Tag mp4s incompatible with output codec id '0'" ? I don't see where I am setting a tag 'mp4s'.) Then I ran the command again, with "-dn" . This seems to work. Complete command line below. One question regarding option "-dn": I checked the manual and it says "Disable data recording". So what is "data recording"? Are subtitles also a kind of data? What about meta data, will that be killed by "-dn" ? Thanks a lot in advance.
