Niklas Haas ae84aa775f swscale/utils: split off format code into new file 
utils.c is getting quite crowded, and I need a new place to dump a lot of
format handling code for the ongoing rewrite. Rather than bloating this file
even more, start splitting format handling helpers off into a new file.

This also renames the existing utils.h header, which didn't really contain
anything except the SwsFormat definition anyway (the prototypes for what should
have been in utils.h are all still in the legacy swscale_internal.h).

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 means to alter decoded audio and video through a directed graph of connected 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.
  • Additional small tools such as aviocat, ismindex and qt-faststart.
