Andreas Rheinhardt 76f244b84e avformat/internal: Use forward declaration for AVCodecDescriptor 
This avoids including lavc/codec_desc.h everywhere and thereby
forces users to include it directly instead of lazily and potentially
unknowingly relying on indirect inclusions.

Also add the proper inclusion to libavformat/demux.c, one of the
two files that actually use the new field.

FFmpeg README

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

  • 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.
