Marvin Scholz e62824835d lavfi/vf_xfade: rewrite activate inputs handling 
The old code was not properly handling a bunch of edge-cases with
streams terminating earlier and also did not properly report back EOF
to the first input.

This fixes at least one case where the filter could stop doing
anything:

ffmpeg -f lavfi -i "color=blue:d=10" -f lavfi -i "color=aqua:d=0" -filter_complex "[0][1]xfade=duration=2:offset=0:transition=wiperight" -f null -

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.

Documentation
