doc/ffmpeg: slightly rework introductory examples
In particular, add a sentence to introduce the example, and add a simpler starting example with no options. Also use different format for input.avi and output.mp4, to convey that the conversion also works on the container format. Address issue: http://trac.ffmpeg.org/ticket/8730
