Anton Khirnov 70ecb8238c lavd: deprecate the bktr device 
It implements BSD-specific support for very old analog capture cards,
which are highly unlikely to be useful today. After being added in 2005,
there were never any commits to it beyond compilation fixes and generic
maintenance. There have also been zero trac tickets for this device, and
the only related web search result I found concludes that it does not
work.

The code also does some unacceptable things, like messing with signal
handlers and storing its state in global variables.

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.
