Niklas Haas 5f4cbb5617 fftools/ffmpeg_sched: choke inputs during filtergraph configuration 
Currently, while the filter graph is being initially created, the scheduler
continues demuxing frames on the last input that happened to be active before
the filter graph was complete.

This can lead to an excess number of decoded frames "piling" up on this input,
regardless of whether or not it will actually be requested by the configured
filter graph. Suspending the filter graph during this initialization phase
reduces the amount of wasted memory.

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.
