Anton Khirnov 156a0217d1 lavu/opt: consolidate common prologue for av_opt_set*() 
The options-setting functions share several operations at their
beginnings - locating the option and the object to operate on, handling
the read-only and deprecated flags, and constructing the pointer to the
target value. Some of the functions also do not perform some of the
checks, although they should. E.g. a deprecation warning is currently
only printed for av_opt_set().

Introduce a prologue function that is called from every av_opt_set*()
and performs all these common initialization operations.

Librempeg README

Librempeg 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.

Documentation
