Is it possible to manually (through commandline args)
tell it to copy all streams across without the

How is this option bugged?




Perhaps I am reading what you wrote incorrectly:

"Note that if you specify -map 0 (to copy all streams), all
output audio tracks except the first one will be silent....This is probably trivial to fix "

If when asked to copy all the streams with -map 0 (implying they will be copied as is) they are copied silent (without sound?) doesn't that imply that it does not work correctly? Shouldn't they be copied *with sound* and not silent? Or why would it need to be "fixed"? To me, this implies "bugged"? Am I reading this incorrectly?
