Nicolas Gaullier de976eaf30 avfilter/framesync: fix forward EOF pts 
Note1: when the EOF pts is not accurate enough, the last frame
can be dropped by vf_fps with default rounding.

Note2: vf_scale use framesync since e82a3997cd,
so this is a very commonplace scenario.

For example:
./ffprobe -f lavfi testsrc=d=1,scale,fps -of flat \
  -count_frames -show_entries stream=nb_read_frames

Before:
streams.stream.0.nb_read_frames="24"

After:
streams.stream.0.nb_read_frames="25"

  • 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.
