The file exists, so why aren't you trying to execute it?  "./ffmpeg"
means a file called "ffmpeg" in the current directory.  Type that into
the shell and press enter.

If you are more familiar with how Windows operates, be aware that most
other systems do not have the current directory as part of their path
variable.  This means you cannot execute a file in the current directory
by simply calling its name, you need to tell the system which file you
want it to execute.

When you finally manage to run it, you should see something like:
