I would give you several recommendadtions for this command, but I'm not
totally sure what you're trying to do. I assume you want to take a
variety of inputs and resize them all to be 480 pixels wide while
keeping the aspect ratio, and then playing these outputs on your web site
with a Flash player such as JW Player or Flowplayer.

What distro/OS/system are you using? Can you show the output of "ffmpeg"?

What is "everything"? Can you be more specific than "not getting the same
result"?
