Andreas Rheinhardt ee485b4051 avformat/internal: Don't auto-include os_support.h 
It includes various Windows-specific headers when compiling
for Windows and these sometimes cause issues: E.g. winbase.h
defines IGNORE, which clashes with a macro used in the Matroska
muxer (since 884653ee5b) and demuxer.

This header provides fallback defines for various stuff that is
mostly not used directly by (de)muxers at all:
mkdir, rename, rmdir, unlink, access, poll, pollfd, nfds_t,
closesocket, socklen_t, fstat, stat, lseek, SHUT_(RD|WR|RDWR)
and various POLL* constants.

Ergo fix this issue by not auto-including this header in lots
of places via an inclusion in internal.h and instead include
it everywhere where the above stuff is used (most of these
translation units already included os_support.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.
