Comment (by cehoyos):

 -dn means "do not process data streams" - if you try the command line
 without -dn, FFmpeg will protest that the data stream cannot be copied.

 Allow me to repeat that - depending on your use case - -map 0 -codec copy
 may not be the best option: It copies large audio tracks that are silent.
