[FFmpeg-user] Tag mp4s incompatible with output codec ?

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.

Best regards, Gabriel
