Doesn't -c enable encoding or decoding (as well as the certainly trivial
'copy') of a stream, depending upon the choice and the existing stream's
codec?  Encoding is not a trivial workload :-)  Can you clarify that a
bit more? *I learn more from ffmpeg-user mail than my best efforts using

This is great to know!

What you are saying is:  ffmpeg reads in the entire serial string of
commands/actions and, when duplicate commands/actions are identified,
programmatically uses the last entry. 

Is this the case with all commands?
