The point is that ffmpeg does not copy the input file to the output file
and stop when "something" says 5 minutes.  ffmpeg will read and parse
until it finds the "start" then it'll demux the streams and start
providing frames.  At this point ffmpeg will select what streams are put
into the output.  The output then starts receiving frames and begins to
mux them.

If you want to provide a sample of the *input file*, why would you want
all that ^ done to it?
