Dale Curtis 01763144dc Avoid corrupting diagnostic state with _Pragma changes. 
The macros for ICC and MSVC correctly push and pop the diagnostic
state of the compiler when disabling deprecation warnings. The
ones for clang/gcc should do the same. Without this, if a blanket
deprecation warning is applied to the code base it'll be flipped
back on incorrectly with FF_ENABLE_DEPRECATION_WARNINGS.

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.
