[FFmpeg-user] Difference between ffmpeg command line and shared object?

[Brian Rasmusson]

I'm researching a project where I need to use a command line version of 
FFmpeg instead of the shared libraries directly.

I have a programmer lined up to do it, but he says that the options you 
can set using the shared library directly cannot all be set using 
command line parameters to the ffmpeg executable. Is this really so, or 
is there a way to build up a long command string and have ffmpeg.exe 
parse it, if not all options are available as separate command line 
parameters?

Thanks,
Brian
