Ganesh Ajjanagadde 254c64c574 cmdutils: silence unused warnings under --disable-swscale, --disable-swresample 
This patch silences such warnings by placing initializations under a header guard,
see e.g
http://fate.ffmpeg.org/log.cgi?time=20150919095430&log=compile&slot=x86_64-archlinux-gcc-disableswscale,
http://fate.ffmpeg.org/log.cgi?time=20150919095048&log=compile&slot=x86_64-archlinux-gcc-disableswresample
for examples of such warnings.
It also has the benefit of placing library specific #defines next to each other.

FFmpeg README

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

Libraries

  • libavcodec provides implementation of a wider range of codecs.
  • libavformat implements streaming protocols, container formats and basic I/O access.
  • libavutil includes hashers, decompressors and miscellaneous utility functions.
  • libavfilter provides a mean to alter decoded Audio and Video through chain of filters.
  • libavdevice provides an abstraction to access capture and playback devices.
  • libswresample implements audio mixing and resampling routines.
  • libswscale implements color conversion and scaling routines.

Tools

  • ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
  • ffplay is a minimalistic multimedia player.
  • ffprobe is a simple analysis tool to inspect multimedia content.
  • ffserver is a multimedia streaming server for live broadcasts.
  • Additional small tools such as aviocat, ismindex and qt-faststart.

Documentation
