Andreas Rheinhardt d4e29d9c5e avfilter/fifo: Remove unused functions and headers 
The functions were forgotten in 03c8fe49ea3f2a2444607e541dff15a1ccd7f0c2;
removing them also means that the avassert.h and samplefmt.h headers are
no longer used any more, so they have been removed, too.

Moreover, video.h is unused since b077d8d908
and channel_layout.h is since fdd9663781.
Both headers have therefore been removed, too.

FFmpeg README

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

Libraries

  • 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.
  • Additional small tools such as aviocat, ismindex and qt-faststart.
