Merge @chapter Introduction and @chapter Description into a single

Browse Source 
section, and make the whole rendered in the man output.

Simplify layout, and make it more consistent with that of the other
man pages. Also I cannot see a good reason for keeping split the two
sections.

@c man begin DESCRIPTION
FFmpeg is a very fast video and audio converter. It can also grab from
a live audio/video source.
@ -21,6 +21,35 @@ bitrate you want.
FFmpeg can also convert from any sample rate to any other, and resize
video on the fly with a high quality polyphase filter.
As a general rule, options are applied to the next specified
file. Therefore, order is important, and you can have the same
option on the command line multiple times. Each occurrence is
then applied to the next input or output file.
* To set the video bitrate of the output file to 64kbit/s:
@example
ffmpeg -i input.avi -b 64k output.avi
@end example
* To force the frame rate of the output file to 24 fps:
@example
ffmpeg -i input.avi -r 24 output.avi
@end example
* To force the frame rate of the input file (valid for raw formats only)
to 1 fps and the frame rate of the output file to 24 fps:
@example
ffmpeg -r 1 -i input.m2v -r 24 output.avi
@end example
The format option may be needed for raw input files.
By default, FFmpeg tries to convert as losslessly as possible: It
uses the same audio and video parameters for the outputs as the one
specified for the inputs.
