Niklas Haas 2d1aeba8f2 avfilter/vf_scale: fix interlaced chroma for other formats 
This logic only covers the case of yuv420p. Extend this logic to cover
*all* vertically subsampled YUV formats, which require the same
interlaced scaling logic.

Fortunately, we can get away with re-using the same code for both JPEG
and MPEG range YUV, because the only difference here is the horizontal
alignment. (Which I omit touching for now, to avoid introducing possibly
unintended changes in default behavior)

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
