Anton Khirnov d234b4b193 lavfi/avfilter: simplify process_options() 
This function currently treats AVFilterContext options and
filter-private options differently: the former are immediately applied,
while the latter are stored in a dictionary to be applied later.

There is no good reason for having two branches - storing all options in
the dictionary is simpler and achieves the same effect (since it is
later applied with av_opt_set_dict()).

This will also be useful in future commits.

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.
