Andreas Rheinhardt cb92b4bd83 avutil/hwcontext: Clarify documentation of AVHWFramesContext.hwctx 
Correct the names of the format-specific headers (not hwframe_*.h)
and clarify that the user shall ignore this field if there is no
public context associated with it.
In particular, this allows to use this field for the private context
alone if there is no public context. This can't break conforming
API users, because they always have to live with the possibility
that a new public context has been introduced.

  • 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.
