end of file is misleading, you are simply using the input duration as far
as I see. So write that in the help text. Also what happens if the
output is generated from multiple inputs?
Also I am not sure your use case needs a separate option. Anybody willing
to use this in an automated way can also get the input duration with
ffprobe and use the good old -timestamp option to achieve the same result.
