Please always paste your console output, no external links please.

I don't understand above as you asked for conversion in your command
line (there should be no cpu issue if you are not converting).
In your command line, not FFmpeg but x264 is used for the conversion,
look at the presets (ultrafast, superfast, veryfast, faster etc.) to
reduce cpu usage.
