Invalid rational "--fps" forwarding.

Hello.

I use x264 command-line tool with rational "--fps" argument. I've found that the tool can't understand long integers and proceed with error silently.

In my case --sar and --fps arguments are received from a Python application. (Python can operate large integers)
