Anton Khirnov 577708a70a fftools/ffplay: stop using avfilter_graph_create_filter() incorrectly 
This function creates AND initializes a filter, so setting any filter
options after it is wrong. It happens to work when the filter's init
function does not touch the options in question, but is forbidden by the
API and is not guaranteed to remain functional.

Instead, use avfilter_graph_alloc_filter(), followed by setting the
options, and avfilter_init_dict().

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.
